Smartphone food. Portable battery for phone: models, rating, tips for choosing. Where is the best place to buy Power Bank

Modern mobile devices and all kinds of gadgets are equipped with many fashionable and useful features and applications. Yes, and the most complex mobile games amaze with graphics and capabilities. It is thanks to such applications that any smartphone "sits down" almost during the day. Therefore, you need to learn how to choose a more powerful one for your phone. Or pick up an extra

The main reasons why you just need to choose a new charger

So, the phone began to discharge frequently and quickly. First you need to decide on the main cause, and only then look for the most optimal ways to solve the problem. So what could be the reasons for early discharge?

If the smartphone or tablet is new, the instructions say a certain duration of work, but in fact, the device works several times less, then the reason may lie in the settings. As a rule, on the phone itself, you can adjust the brightness and energy consumption, or turn off several applications that draw power.

Another thing is if the smartphone is set up, it worked quite normally for a long time, but over time it began to discharge much faster. Here, most likely, the internal charger or the external battery of the phone is to blame. The only solution is to replace the element. To do this, you can use both a proprietary battery and a universal analogue.

Types of external batteries

Despite the prevalence of cell phones and smartphones, there are still only three main types of batteries in the world:

• Li-ion. This is perhaps the most common external battery for charging your phone. It has a more optimal ratio of durability, safety and energy intensity than other analogues. Also, such elements are endowed with a special “memory effect” and are discharged rather slowly. But they quickly age, and even in the case of constant use.
• Nickel-cadmium. Recognized as the most harmful and were put on the shelf. They were used only in the very first phones because of the low cost. In addition, the higher their energy intensity, the higher the physical size.
• Lithium polymer. These are cheaper and improved external batteries for cell phones. Therefore, such elements adopted all the positive aspects of the original sample, and also became more environmentally friendly.

Features of work and operation

A mobile phone is a fairly complex and delicate mechanism. And each of its elements has its own characteristics and requires certain operating conditions, including the battery itself. Therefore, there are several rules, following which, you can significantly extend the life of the telephone battery:

• When using, it is required to strictly follow the operating rules specified by the manufacturer, i.e. do not overheat, do not wet or overcool.
• Try to avoid physical damage to the element.
• External do not endure frequent blows and falls.
• You should not open the batteries yourself for the sake of interest.
• Replace and recharge the battery only when the device is turned off.
• It is not recommended to constantly charge the gadget for a long time (more than a day).
• The more and more often the battery is used, the better.

Myths about mobile batteries

For all the time of its existence, mobile phones have practically acquired a variety of fictions and legends that scare naive users. Several of them touch on their most important detail.

Parameters to pay attention to when choosing chargers

When choosing an additional external battery for your phone, there are many factors to consider (in addition to the manufacturer and the quality of the materials). As a rule, experts identify several main parameters by which these elements differ. Therefore, knowing these features, you can choose the appropriate option.

• The capacity of the presented battery. The operating time without additional recharging directly depends on it. As a rule, 4000-6000 mAh is enough.
• Current strength. If the battery is used to power not only a smartphone, then you need to choose a device with a power of 1-3 A. For a regular phone, a device that produces 1 A is enough.
• Charging method. It is better to choose a gadget that can be powered from several sources at once: an ordinary power supply and via a USB connector.
• Battery indicator. This element is simply necessary in the daily operation of smartphones and phones. There are several options for displaying the charge: by changing the color or numbers. The numerical indicator provides much more accurate information about the state of the battery, but it also costs much more.
• Number of ports used. Thrifty and prudent users choose specimens with the largest number of them. But, as a rule, the need to charge several devices at the same time is quite rare. Therefore, 2-3 ports are sufficient.

A few things to look out for when choosing batteries

In addition to the main parameters that you need to pay special attention to, there are several additional qualities. They can greatly facilitate and extend the operation of the presented gadgets.

It is best to choose an external battery for the phone, on which the power button will not stand out against the background of the case. After all, if you press it by accident, you can get a rather unpleasant surprise. It will also be useful to have a special flashlight in the device to make it easier to find in the dark.

In order to protect a valuable thing from the ingress of all kinds of dust or water, as well as to protect against small bumps, you need to choose devices with a special case. Such devices will cost a little more, but their service life will be clearly longer.

Fans of modern innovative technologies will appreciate the presence of such features as Wi-Fi and NAS Server. With the help of them, you can not only freely use and distribute the Internet, but also save various data on a special memory card.

Useful for any battery and After all, in the summer we are not always near any power source.

To purchase a quality battery that will last long enough, you should approach this issue with all seriousness. Before making the final choice, you need to familiarize yourself with the most common options, compare features and reviews. And only then it will be possible to buy for the phone.

1. First of all, this device should be convenient, light and compact enough to fit freely in any bag.
2. A charger from the same company as the main device will fit much better than similar counterparts. In addition, in this way you can protect yourself from low-quality goods.
3. It is better to clarify in advance whether a return of a purchase is possible, and under what conditions. The charger may simply not be corny.

Comparison of the most common external batteries

There are many external telephone batteries. There are probably as many of them as there are mobile devices themselves. In this case, everyone chooses their external battery for the phone. Reviews are what attention is drawn to in the first place. Therefore, here are some subjective opinions about the most popular models:

• Vampire mini. There is a standard USB connector. It is convenient to adjust the current and voltage. Among the shortcomings - low efficiency.
• boost stabilizer. This battery charges almost all known mobile devices, and can also be charged from any power source. The only drawback is that an external battery pack is required.
• Specialized energy storage device "Proglot". Universal battery. It has a variety of dedicated connectors for all kinds of devices, and the internal batteries can be easily replaced. Minus - in the absence of adapters.

Universal external battery

As the world's all-knowing statistics show, almost every city dweller has two or more mobile devices, as well as a laptop and several other gadgets. Therefore, many seek to purchase a universal external battery for the phone, but in such a way that it fits other devices.

Such a choice allows you to kill several "hares" at once: the ability to charge all available gadgets from one device at the same time, saving money and space. At the same time, the operating rules for such devices are the same as for narrowly focused batteries. In addition, modern stores can offer a huge number of different batteries in terms of price, characteristics and quality. Therefore, it is the best choice for any user.

It is not necessary to buy an additional power source for a smartphone. If desired, and with certain abilities, you can easily make a homemade external battery for your phone.

The most common homemade products are charging from batteries and from the sun. Each of them has its own characteristics. In the first case, you need a resistor, a suitable plug, 4 batteries and a special box for them. The principle of operation is simple - a resistor connects the power supply to the plug and transfers the charge to the mobile device. The downside is that the batteries need to be changed constantly.

In the case of solar charging, you can simply buy special flashlights that are charged from the sun, and take the necessary elements from there. Further, a circuit is connected by means of a diode, and the structure is refueled into some box.

External Battery - portable phone charger

What is Power Bank

In essence, a Power Bank is a battery. An additional battery that has a larger volume and is able to accumulate more charge. Thanks to the function of distributing the charge, it is able to transfer it to other mobile devices.

External battery: advantages

Power Bank is an indispensable thing that allows you to charge your mobile device in a situation where there is no access to stationary charging from the network, computer or laptop.

The portable charger is easy to use, small in size and light in weight. It is universal and suitable for any mobile devices.

You can be sure that thanks to this small box, on long trips, your smartphone or tablet will always have an additional recharge. The main thing is not to forget to charge the external battery itself and take a USB cable!

Which Power Bank is better to buy

Where is the best place to buy Power Bank

To search for an online store where you can buy a portable external battery (Power Bank) at a good price, you can use specialized online trading platforms.

Everyone calls this item differently, but they miss it equally much when the battery is at zero and there is no outlet nearby. The arsenal of gadgets is now not limited to a smartphone, it often comes with wireless headphones, smart watches, fitness bracelets, Bluetooth speakers ... For their owners, the question of how to feed this whole menagerie is particularly acute. We tell you how external batteries differ from each other, how to choose the right one for you and how to use them correctly.

How much do your devices consume?

You need to start by answering this very question: after all, an amateur climber shooting on a GoPro camera and editing video on a tablet while hiking in the mountains needs more energy than an office manager swimming with a player in the pool. For clarity, here are the average battery capacities for some types of devices:

action camera: 900 mAh;

wireless headphones: 150 mAh;

music player: 1800 mAh;

wireless speaker: 3000 mAh;

smartphone: 3000 mAh.

Taking approximately such figures as a basis, it is enough to remember which devices you use most often and plan to charge; get something like this: 1800+150+3000=4050 mAh.

At first glance, this is the capacity that is needed in wireless charging to replenish the battery of all devices. In fact, it is desirable to multiply this number by another 20 percent in order to compensate for losses from heating, the influence of low temperatures outside and other factors. It turns out 5000 mAh.

The second characteristic that you need to pay attention to is the output voltage and current strength. It is not necessary to remember physics, because most chargers have an output current of 1 A or 2.4 A. The greater the current strength (A), the better. After all, smart portable technology can limit the current to the desired value, but get more - no.

In general, portable chargers are divided into five conditional categories.

Pocket Helpers

How to calculate: capacity up to 3000 mAh

Such chargers are a chic addition to the glove compartment of a car, bag and backpack, as well as the inner pocket of a skier's jacket. They are made, and they will help when you need to add a little charge to your smartphone or power an action camera. You can choose a compact charger according to your liking in design, and it is not at all necessary to study the characteristics of the output current: often the real output current is 1 A, which means that the charging time will be about three hours.

Power bank can be safely charged for future use, so that it lies just in case. The self-discharge of such devices is very slow; in a year, your portable battery will sit down only by 10-15 percent.

Workers for every day

How to calculate: capacity is about 5000 mAh

These everyday charges are most often found in passers-by in the hands and in the car, where it is possible to feed the battery from the cigarette lighter. Convenient, compact and efficient assistants for active smartphone owners who are unable to change the battery in non-separable device cases. And at the same time lovers of short trips and trips on their own. You should choose such charges according to the output current strength from 2.1 A, and also give preference - the coolest battery cells are shaped like thick batteries.

How to calculate: capacity from 8,000 to 12,000 mAh

If you are a gadget lover and pay for purchases in a store not even with a smartphone, but with a watch, the collection of equipment will be able to feed more powerful charges. In this capacitive group, they have a strong output current, and even accelerated charging technologies, so the design and number of ports for simultaneous charging becomes the determining factor when choosing. Please note: often the second USB output is weaker than the first, so we recommend that you clarify this parameter in the specifications.

The accelerated charging technology significantly reduces the time to the coveted 100 percent on the smartphone battery. An hour, a maximum of one and a half - and the phone is completely ready for work. However, pay attention to which accelerated charging technology your gadget supports. QuickCharge, SuperCharge, Adaptive Fast Charging - all these are different types that do not combine with each other. Thus, the smartphone can be charged quickly via SuperCharge (if it is Huawei P10), and the Power Bank can support QuickCharge. In this case, it will be possible to power the gadget, but the charging time will be normal.

Pocket Power Plant

How to calculate: by capacity 15,000-20,000 mAh

Many of these are ready to charge even the MacBook 12 and other laptop models with a USB Type-C charging connector. And at the same time distribute energy to several devices at once without power drops on one of the USB outputs. These charging stations are good for everyone, but nothing can hide their size and weight. Such an ailment limits their scope, but if you need confidence in the operation of all the equipment for several days in advance, there is hardly anything that can be compared with them in terms of recoil efficiency.

Wireless portable chargers

Put your smartphone on and see

More and more new smartphones are equipped with Qi standard wireless charging modules and analogues - for example, Samsung Galaxy S7, S8, iPhone 8, X. It is enough to put such smartphones on wireless charging, and the battery will start charging automatically. No wires and confusion, because the technology is based on magnetic induction. Most of the smartphones that support wireless charging work exactly according to the Qi standard, and recently, fast ones suitable for them have begun to appear. When choosing such charges, it is better to slightly increase the margin in capacity to compensate for the loss of energy for such an effective transfer process. By the way, such chargers themselves can be charged from stationary sites.

Instead of output

It is not difficult to deal with the variety of portable chargers if you compare the model you like in terms of parameters and know what kind of capacity you need. It is not advisable to take chargers with a margin, because this will affect the convenience of carrying with you, without bringing much benefit. Having decided on the appearance and capacity, make sure that you have the necessary bonuses - wireless or fast charging, after which you can safely buy a device that is convenient, practical and suitable for you.

Contrary to popular belief, Power Bank does not damage the battery of a smartphone. Just feeling that salvation is always at hand, gadget owners begin to use the device more actively, charge it more often and thereby generally increase the number of charge cycles, which is limited for each battery.

Once again, my phone ran out of power by lunchtime - a couple of hours on social networks, downloading new 400 MB podcasts using the 3G network, a few photos - and the battery waved at me. Unfortunately, for many people, this scenario is becoming a reality on a daily basis. Sometimes, when talking with acquaintances, I hear a squeak, and then the conversation is interrupted. They call back from the second number and say the sacramental: "The phone is dead." The presence of chargers in the car, at the workplace is by no means a panacea. Someone is used to carrying a charger with them and in restaurants chooses places closer to outlets. As my friend jokes, phones are wired again, but now we're tethered to an electrical outlet.

One of the partial solutions to this problem is the choice of an external charger that you can carry in your bag, take on trips and hikes. The cost of such devices varies in a very wide range, the number of manufacturers is large, and often the eyes run up from the diversity of the offer. This guide will focus on how to choose the right external charger, but before I get to that point, let me dissuade you.

Energy consumption in modern smartphones - how to save energy

In the comments to the Buyer's Guide. Choosing a smartphone” I came across statements in which people claimed that the given operating time for certain devices differs from the real one. For example, the article says that the device can easily work a full day, and it sits down at the commentator's place by lunchtime. An attempt to understand this issue thoroughly showed that many people do not think that their smartphone already has all the tools to reduce power consumption and extend the device's operating time without sacrificing performance. This point of view was also popular - having bought an expensive phone, I am not going to set it up or use it not one hundred percent, I want it to work out every penny. It is impossible to agree with such a view, since any technical device has operating modes, settings that are unnecessary for many consumers, turning them off does not affect the comfort of use. I am sure that people with such a position in life do not need to buy an external battery, they still will not have enough of it for a long time. Marketing often takes the place of common sense - when you hear people say they don't want to downclock the processor in their smartphone, you realize that they don't know or even realize that the processor runs at a very low frequency most of the time. High frequencies are needed for “heavy” computing tasks, for example, three-dimensional graphics in games, in which case the smartphone automatically gives the maximum frequency, otherwise applications will not work.

Therefore, it is possible that you do not need an external battery, but you should deal with the power consumption on your smartphone (for tablets, this is not so critical and important, although exactly the same rules apply there). And having already exhausted all the possibilities for extending the operating time with regular means, it is worth resorting to an external battery.

In the next two videos, I provide power management tips for Android as well as iOS. These tips are universal, you can apply them on different devices, but you should remember that not all settings and features are present on all.

External battery - what types are there, what to look for

When buying an external battery, they often choose the one that comes to hand, not paying attention to technical details, which leads to disappointment in the future. I will try to talk about all the pitfalls and start with the obvious - the size of the device. Unfortunately, there are no miracles in the world, and the larger the battery capacity, the more space it takes. You need to decide what you need the battery for - only for a smartphone or do you still plan to charge the tablet as well. Psychologically, we want to choose universal solutions and very often buy into the fact that on the box they promise us charging not only smartphones, but also tablets. Unfortunately, these promises very often turn out to be wrong or misleading. To charge modern tablets, you need a battery that delivers a current of 1A, and also has a capacity of 12,000 to 16,000 mAh, which will allow you to charge the tablet at least half. Such a device will weigh about 350-400 grams or even more. Calling it compact is a bit of a stretch, although simpler external batteries with a capacity of 4000 mAh may not be small.

Size and weight - this is the first parameter that you need to pay attention to. For myself, I came to the conclusion that I need an external battery only for a smartphone, after all, to put the battery on a tablet, you need a full day of light and continuous play. I admit honestly that I fail faster than the battery in the tablet, I just get tired of playing or watching movies so much. On hikes where I would have time to work on a tablet in the forest, I don’t go either, there are always sockets and time to recharge the tablet. But it is possible that you have a different usage scenario and then you need to look at a universal device or buy two different external batteries.

For a smartphone, I need an external power supply. Given my lifestyle, I was looking for a device that would allow me to charge a smartphone with a 1500-2100 mAh battery or so at least twice a day. Since I was going to wear it both in my hands and in clothes, sometimes in a bag, the size of the device became a priority. In Hong Kong I bought a 6000 mAh battery under the name VTank, I was bribed by the size and metal case. Of the minuses, I note the weight of the device, it delays the pocket (about 250 grams).

I am sure that you will decide on the size and weight of the device on the ground, based on how you will carry it. Even in a lady's bag there is enough space for such a battery. But there is a little trick to keep in mind - when you charge your smartphone, you will most likely want to use it. See how these two devices fit in your hands while charging (or imagine if you can't feel it).

Case materials - this is another parameter that is not very important, but from an aesthetic point of view it warms the soul of many. Metal or plastic case - what to choose? There are no features here, it is worth remembering only that their reliability is approximately the same, but the weight of the metal one is greater.

Battery capacity and current are two main parameters that will be important to you. There is no universal rule, but you need to select a battery with a capacity at least twice as large as the capacity of your battery in a smartphone (for a tablet, this rule does not apply for obvious reasons, there are champion batteries). At the moment, the most common batteries are 4,000 - 6,000 mAh, they are standard. There is no point in choosing batteries of a smaller capacity, their cost is not much lower, and there is almost no sense from them.

When choosing Chinese batteries, there is a high risk of encountering a discrepancy between the declared parameters and the real ones. For example, they will tell you that the battery capacity is 12,000 mAh, but in fact it will be only half. On the other hand, this deception is innocent, since you will not be charged extra money for a “large” capacity. Usually, the seller wants to please you and talks about a larger capacity to convince you that you made a good deal - bought such a good battery for cheap.

There is no point in looking for batteries from unknown companies, there are many offers from different manufacturers on the market, the prices are about the same (I'm not talking about retail, rather about the Internet).

The best choice is a 6,000 mAh battery (this is the middle ground that will suit most people), or a 12,000 mAh battery or higher. It should be borne in mind that external batteries have a discharge current, depending on the design, manufacturer, it can vary greatly.

Batteries often use 3.7 V batteries inside, while 5 V is required at the output. The boost circuit is not ideal and eats up most of the external battery capacity, so this parameter should be taken into account when calculating how many times you can charge your phone. Many external batteries with a capacity of 4,000 mAh can only give 2,000 mAh, that is, one charge of a phone with a battery of 1,500 - 2,000 mAh.

Another important point is the current strength that the battery produces. To charge most smartphones, 0.5 A is enough, this is the minimum current strength in such devices. Often, to charge tablets and a number of smartphones, a current of 1 A or more is required, this parameter should be paid close attention. If the battery has several outputs, then the connected load can vary in the range of 1-3 A. In order to determine what charging current you need, look at the marking of the charger from your tablet or smartphone.

Charging the battery is another non-obvious point that is not paid attention to, but in vain. By and large, all external batteries can be divided into two large classes - those that are charged only from the computer's USB connector, and those that can be charged from the AC mains. In the second case, use a standard miniUSB, microUSB connector, or a charger that is included in the kit. It makes no sense to discuss the first type of devices, they have almost disappeared and are of no interest.

The lack of charging from a regular network is a serious disadvantage, since in this case you will have to recharge the battery only from the computer and it will take much longer, and you will not be able to charge it to its full capacity (the USB port does not provide enough current). It is necessary that the external battery be able to charge from a regular USB connector, but also be able to use ordinary sockets.

Device charging indicators - usually there are three, sometimes four LEDs on the case that show the battery charge. Unfortunately, they give a very rough idea of ​​how long the battery will last. In the case of a battery that has been used for about a year, you can completely forget about the last division, as a rule, the indicator starts to lie and the charge is no longer enough. There are external batteries with digital indicators, they are much clearer and more visual, but you will have to pay 20-30 percent more for them than for similar batteries without such displays. The addition is nice, but it's up to you to decide whether it's worth the money.

The number of USB connectors on the device is an optional parameter, but it should also be taken into account. Many devices have two, and sometimes four, or even five USB ports. This allows you to connect multiple devices to the charger at once. In my opinion, two USB ports are enough for the eyes, and their simultaneous use is a very rare case. In my practice, this is rather an exception, a couple of times I powered the devices of my colleagues like that, but I didn’t use it myself.

On / off button - must be recessed into the case to avoid accidental pressing in pockets and subsequent battery discharge. In most models, this parameter is not given any importance, which is sad.

I hope that, remembering what to look for, you will not get into trouble when choosing an external battery for your smartphone or tablet, although I doubt the second use case. But without recommendations on what to look for and how to buy such batteries, this guide would be incomplete.

Where and how to buy an external battery - prepare a sled in the summer

Unfortunately, my job of choosing the perfect external battery is complicated by the fact that there are so many of them and it is impossible to describe everything. Models of one manufacturer may be presented in your city, and completely different ones in the next one, there is no universal recipe.

Most of the batteries sold in Russia with a capacity of 4,000 mAh cost in the range of 2 to 3 thousand rubles, batteries with a capacity of 8,000 mAh cost from 3,500 rubles and more, sometimes reaching 5-6 thousand rubles. In my opinion, there is no point in buying such expensive batteries, since you overpay at least two or even three times the real cost of such devices. A reasonable purchase looks like ordering a battery from China or from sites selling electronics, then its price with delivery will be much lower. For information on how to buy abroad, we have a separate Buyer's Guide.

To search for various models of external batteries, you can use the Focalprices website (link is the search result for such devices). A fairly wide selection of such batteries on eBay. Or you can look at such batteries.

If for some reason you do not want to deal with delivery by mail, then you can look for batteries in Russian online stores, the offer is varied, but the prices are higher.

I hope that in this article I have described in detail all the pitfalls and principles for choosing external batteries. It is worth remembering that over the course of a year of use, the battery capacity is reduced to 80 percent of the original face value. You should also treat batteries (both external and built-in phones) as consumables. Once every few years they should be replaced, they, unfortunately, do not last forever.

If one of the manufacturers of external batteries wants reviews of their devices to appear with us, then write to us, we will be happy to test them.

P.S. I would like to express my special thanks to Daniil, who left a very capacious comment about the use of external batteries, much of this comment was included in the "Guide".)

A modern smartphone can be discharged at the most inopportune moment when you do not have access to a power outlet. And during some hike, difficulties are guaranteed - even the best smartphone models cannot work on a single charge for more than three days, while a trip to nature with a tent can drag on for a whole week. Fortunately, this problem can be solved quite simply - just buy an external battery. In this article we will talk about such a device as an external battery for a phone, how to choose.

Which brand to choose an external battery?

This niche of computer technology, of course, has its own production leaders, and these are the brands most often preferred by users.

Hyper

Products under this brand have existed for only a few years, but during this time they have won leading positions in various charts. At first, the manufacturer relied on a large capacity - its main models can charge even a 10-inch tablet, and more than once. But over time, the product line expanded, resulting in less capacious models.

Important! Initially, the batteries of this manufacturer had a rough design, but today the situation has changed - there are models on the shelves with attractive colors and elegant curves.

Remax

Under this brand, the largest number of portable batteries is distributed. The user can easily choose a copy for himself, focusing on his needs. Many models have built-in LEDs that act as a flashlight.

Important! The capacity of such batteries reaches 30,000 mAh - this parameter will be enough to even charge a laptop a couple of times.

Samsung

This is a South Korean company that introduces a large number of unique technologies into its smartphones. It would probably be strange if interesting functions were not found in the external batteries of this manufacturer. The main one is support for relatively fast charging.

Important! If the power is transferred to a compatible device, then recharging up to 50% occurs in just 30 minutes or even faster.

Take a look at the review best samsung smartphones .

Xiaomi

This is a Chinese company that started producing external batteries quite recently. Previously, it specialized only in the production of smartphones. The main feature of Xiaomi products is increased reliability. These batteries are not affected by power surges or any other troubles.

Important! They also protect the device connected to them, which will definitely not get overcharged. We have prepared for you iting phones xiaomi .

Yoobao

The location of this company is located in the city of Ginseng. Like many other Chinese manufacturers, this company relies on a low price for its products. The company also strives to make its range as wide as possible: some external batteries are shockproof, others have increased current and two connectors for connecting devices, and others surprise users with their miniature size.

Important! Here, the Chinese pedigree still makes itself felt - there are a large number of defective products, the capacity of which differs from the declared one.

Rating of the best external batteries - selection criteria

To make it easier for you to choose an external battery for your smartphone, we provide a rating that takes into account the following parameters:

• Price.
• Number of connectors.
• Equipment.
• Dimensions.
• Appearance.
• Real and declared value.

Important! whichever of the batteries you choose, the information will be useful for you, what is the best internet connection for phone .

Best portable laptop batteries

To begin with, consider compact devices for recharging mobile gadgets.
