What is a portable phone charger called? Portable battery for phone: models, rating, tips for choosing. Main technical characteristics
How many times have you suffered from your smartphone running out of power at the most inopportune moment? What if you need to make an urgent call or wait for an important message? It’s good if there is an outlet or computer nearby that you can quickly charge your device from. But what if they are not there? The solution is to use an external battery (power bank). The Internet project “Be Mobile” has collected tips that will help you choose the best option for you.
First, let’s define what an external battery is and what its advantages are. An external battery or Power Bank is a portable high-capacity lithium-ion battery that can be used to charge a variety of mobile devices: phones, smartphones, tablets or e-readers. This battery is capable of storing energy within itself for a long time. You can take it with you to work, school, on a business trip or while traveling.
Portable Charger can be made in various form factors with a body made of plastic, polycarbonate or metal. On sale you can find models in the form of boxes, bars, disks, cones and tubes in a variety of colors.
The Power Bank is charged from the electrical network or from any device with a USB output (for example, a computer or laptop).
All external batteries are equipped with one or more USB ports. Modern phones, smartphones or tablets can be charged using a USB cable, which in most cases is included with the device.
id="sub0">The main parameter when choosing an external battery is energy capacity. Everything here is simple and clear. The larger the capacity, the more energy the device stores, and the more expensive it is. Capacity is measured in mAh - milliamp hours.
Currently on sale you can find portable chargers with a capacity ranging from several hundred milliamp hours to several tens of thousands. You can estimate the level of charge you will need based on the battery capacity of your smartphone or tablet.
For example, in an average smartphone the battery has a capacity of 2,000 mAh, in high-performance and expensive models - from 2,500 to 3,000 mAh. This means that a fully charged 5,000 mAh external battery will be enough for 2-2.5 charging cycles. A fully charged 10,000 mAh external battery will last for 4-5 cycles. If portable charging is necessary for your tablet, then you should choose from models with a larger capacity, for example, 20 or 30 thousand mAh.
Currently produced portable power sources use lithium-ion or lithium-polymer batteries. Depending on the type and design, the nominal battery output voltage may vary (3.7, 4.2 or 7.4 V), while the standard USB power bus voltage is 5 V direct current. Obviously, in this case, a battery with a capacity of 2000 mAh with a nominal voltage of 3.7 V, even under ideal conditions, will not work for even an hour and a half when powering an external load connected via a USB bus and consuming a current of 1 A. In addition, the amount of electricity that can be stored Batteries having the same capacity but different voltage will vary.
Tip 2: look at the current strength, it affects the charging speed
id="sub1">Another factor that affects the charging speed is the current strength. The more amps, the faster the charging speed. For phones and smartphones, this figure should be at least 1 ampere. Otherwise, the process itself will occur extremely slowly. To fully charge, it will take 3 or 4 times longer than from the mains.
For tablets, devices with a current of 3 A or more are preferable. The ideal option is 4 A.
Tip 3: trust, but check, because the declared capacity does not always coincide with the real one
id="sub2">Another important point is the actual capacity of the Power Bank. The fact is that many manufacturers embellish the performance of their products. Of the 50 models of portable chargers that we tested over the past year, 46 had a capacity significantly less than stated. On average the difference was 25%.
For example, the manufacturer indicated that the external battery has a capacity of 10,000 mAh, but in reality it is 7,800 mAh. The difference is due to both the dishonesty of the developers and the improper storage of batteries during transportation and subsequent sale.
The actual capacity is also affected by such an indicator as self-discharge.
On average, external batteries with a full charge are discharged by 5% within two weeks. This is worth considering if you do not use Power Bank for a long time. To activate electrolytic reactions, you should charge the device before use.
Keep in mind that the battery capacity will decrease over time. Our measurements show that with active use, a high-quality battery loses its capacity by 15% per year, the cheapest models - 35%.
To monitor the charge level, almost all Power Banks use LED indicators. And some external batteries are equipped with LED displays that show the exact state of charge in percentage.
Tip 5: choose a power bank with multiple USB ports to simultaneously charge your friends’ smartphones
id="sub4">Some models of portable chargers have several USB ports for connecting two, three or even more mobile devices at once. This option is suitable for simultaneous recharging, for example, when you go on a trip with friends. It's comfortable. You can all charge your phones, smartphones and even tablets together.
You often ask us where you can be guaranteed to buy a high-quality external battery cheaply. We cannot give a definite answer. Of course, the reliability of purchasing from a large Russian online store or retail chain is higher, but the prices there are also higher. It is worth remembering that little-known Chinese sellers have a peculiarity: they can deceive. Their external batteries are much cheaper than their branded counterparts; they often indicate a capacity 2 or 3 times higher than the real one. Prices that are too low can be a trap. Although branded Power Banks in such stores can be fakes.
Compact
id="sub5">If you need compactness, you can pay attention to ergonomic models, for example, Anker Astro E1. This battery will not take up much space in your bag or pocket.
Universal
id="sub6">The ideal option would be batteries with a capacity of about 10,000 mAh. This is approximately three times more than the battery of a modern smartphone, which means that even taking into account the loss of energy during charging, it will be enough to fully restore the gadget’s charge several times. A high-quality example of such a power bank is the Anker PowerCore 10400 mAh model.
Another option for a high-quality external battery with universal functionality is the Aukey PB-N42 10,000 mAh.
Supports fast and wireless charging
id="sub7">If universal options are not your option, then you should pay attention to models with additional functions. For example, a power bank with fast charging support will be able to charge compatible gadgets much faster than usual. If the battery is capable of delivering a consistently high current (about 2A), then even without fast charging support, your gadgets will charge stably and relatively quickly.
Among the ones we recommend is the Baseus Wireless Charge Power Bank 8000 mAh external battery. Its main feature is the presence wireless charging Qi standard. That is, to charge a smartphone, you don’t need to connect a wire to it, just put it on an external battery and that’s it. Charging started. In addition to wireless charging with a current of 1A, the device supports a wired USB connection of two compatible devices, while the output current to the USB connectors is 2A.
A good option for iPhone is the Zikko PowerBag 6000 mAh external battery. The main difference from popular Xiaomi external batteries is MFI certification, which means the battery is compatible with all Apple devices. The device supports fast charging - the output current to the USB connectors is 2.4 A. In order to monitor the battery capacity, there are special LED indicators at the end. A nice bonus is that the smartphone is connected to the battery using the included Lightning cable.
With record capacity
id="sub8">If you need a strategic boost of power, check out the HyperJuice 26,000mAh AC Battery Pack. This giant can quickly charge absolutely any device, including a tablet, other portable equipment and even a laptop. There are 2 USB output connectors here. One provides a maximum charging power of 3A at a voltage of 5W, and the other provides a current of 2.4A. A nice bonus is the ability to provide 220W power to any electrical appliances with a power consumption of up to 100W. You can connect a laptop, a flashlight, and even a blender to this battery.
The HyperJuice AC Battery Pack case is made of aluminum alloy, which perfectly protects the device from external mechanical influences.
We hope that our tips will help you buy a truly high-quality external battery and charge your phone, smartphone, laptop or e-reader without any problems.

Why do you need an external battery?
How often have each of us encountered the battery on our favorite smartphone running out at the most crucial moment? With the development of technology, this question has become rhetorical. Just ten years ago, few people could be surprised weekly time battery life apparatus. You won't see this now.
As a rescue in a situation "Battery low" and the guests of my story today were invented - external batteries. What are these things and what do they eat them with?
*they are not eaten
How does an external battery work?
External battery– it’s like an internal battery, only external (your Captain Obvious). Several batteries are soldered to a small controller board, to which, in turn, connectors are attached for charging our gadgets and the battery itself. The reliability of the entire structure depends mainly on the use of high-quality components and adherence to the manufacturing process.
From this follows the main rule - do not buy extremely cheap portable batteries. In the vast majority of cases, they will be assembled as crookedly as possible, from the lowest quality components. I’ll tell you a little later about the minimum price a high-quality external battery can have.
Main characteristics of a portable battery
Their three, these are the ones you should pay attention to when choosing (and only then look at the design).
1. Capacity
The most important characteristic that determines how long a battery can provide energy to a particular device. To put it simply, this is the operating time of the battery without additional recharging. It is measured in ampere hours, in our case – in milliampere hours (mAh, mAh).
Basic rule: for comfortable use, the capacity of the external battery must be at least 2 times more than the battery capacity of the device being recharged.
For example, the iPhone 6 has a battery capacity of 1 810 mAh. In order not to be afraid of being left without communication for a day when constantly using a smartphone, you should choose a battery for it 3 500-4 000 mAh. This is guaranteed to be enough for one full battery charge.
Golden mean batteries with a capacity of about 6,000 mAh can be considered for comfortable use of a smartphone for several days. A capacity of more than 12,000 mAh is extremely versatile and is suitable for users of smartphones and tablets, including at the same time.
2. Current strength when discharging
The standard is a connector with a current of 1 A for charging smartphones and 1.5 - 2 A for charging tablets. If we talk in simple words, the current strength in the battery indirectly affects the charging speed of the connected device.
In this case advice already two. First, keep an eye on matching battery current and your smartphone manufacturer's specifications. The best indicator for this will be the included charger. For example, with iPhones, Apple charges with a current of 1A. With iPad – already 2A.
Accordingly, it is advisable to charge the iPhone from the 1A port in your battery, and the tablet from 2A.
The second tip concerns primarily tablet owners Apple: You need a 2A portable battery. Don't even look at 1A, it's simply not strong enough to power the huge battery in your iPad. To find out the amperage before purchasing a battery, simply look at the markings next to its USB port. In 99% of cases everything is clearly written there.
3. Size and weight
Golden Rule: the higher the capacity and the more ports, the larger there will be a battery.
There are again two pieces of advice. First - choose a battery to suit your regime using a smartphone or tablet. It’s one thing to be a fragile girl who just wants to sit on social networks and chat with a guy for one or two hours. And it’s completely different when a stern bearded man – a lover of hiking and bard songs – wants to listen to these songs in the forest, also with clips on YouTube, for two or three days. A small and portable battery is enough for a girl, but a bearded man should immediately buy a “tank” with 15 thousand mAh, no less.
Second tip - don't be fooled by the huge capacity battery in a small or amazingly cheap device. This does not happen and will never happen. Stay realistic.
All other “goodies”, such as the presence of a flashlight, a solar battery, a shock-resistant case, etc., are not necessary for daily use (although sometimes useful), and only add an extra penny to the price of the product. The only really necessary option is a battery charge indicator, but almost all models have it, so we won’t focus on it.
So, which external battery would be ideal for a modern gadget? To play games, watch a movie, and not be left without communication for several days...
- Capacity: 6,000 mAh for a smartphone and from 12,000 mAh for a tablet;
- Current strength: one connector for 1A, or two connectors for 1A and 2A;
- Weight no more than 250 grams (but if you are a stern bearded man, then this is not so important);
- Necessary options: charge indicator and power button recessed into the body.
Everything else is up to you, there are a lot of different design solutions and interesting options.
Minimum price for a quality battery
Let's look at a high-quality battery from one well-known manufacturer. Capacity – 10 400 mAh. Many people consider this battery a reference, and it’s hard to argue with them. Its approximate price consists of:
- 4 samsung batteries ICR18650-26F – $20.
- Electronics, assembly and packaging – $5-10.
- Logistics and seller’s interest – $5-10.
Total – $30-40 or about 1200-2000 rubles(at the current exchange rate). This figure may fluctuate, but the point is different...
A 10,000 mAh battery from eBay for 600 rubles is too much good to be true. Not to mention 20 thousand mAh for the same money - and other nonsense that Russian buyers willingly believe in, flaunting “savings” left and right. Don’t be fooled by cheap prices, trust products from well-known brands, read reviews and, above all, think. It's the most important.

External Battery - portable phone charger
What is Power Bank
Essentially, a Power Bank is a battery. An additional battery that has a larger capacity and can store more charge. Thanks to the charge distribution function, it is able to transfer it to other mobile devices.
External battery: advantages
Power Bank is an indispensable thing that allows you to charge 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 device.
You can be sure that thanks to this small box, your smartphone or tablet will always have additional charging on long trips. 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.
Do you have enough battery capacity on your smartphone or tablet? If yes, then we are very happy for you. But if you regularly find yourself in a situation where “it’s only 19:00, but your smart phone is already at zero,” we recommend purchasing an external battery. What they are, what to look for, and how to choose the right battery - read our article.
Just some 10 years ago, anyone mobile phone it held a charge for up to 10 days without any problems, and situations with a “sudden” discharge were rare, and as a rule were the result of a faulty battery. Today, the owner of a smartphone capable of living for more than 10 hours in active use mode is looked at with admiration and envy, and the habit of carrying a charger with you, or keeping several (at home, in the office, and in the car) looks just as normal, like morning coffee. Yes, progress. Yes, new technologies. But how many times have we been left without communication at an important moment due to the fault of a dead smartphone?
Of course, you can continue to use the archaic “dialer” from Nokia or Philips, which needs to be charged once every 2 weeks. Or you can buy yourself a magical device that is indispensable for the owner of a modern phone: an external battery.
External battery, what is it?
External battery, or PowerBank is a portable power source that can “feed” all your gadgets. Structurally, it resembles a regular battery of a portable device: batteries, of which there can be from 2 to 10, are connected to the controller board. On the same board there is a connector for USB connections cables from gadgets. And all this is wrapped in a durable (or not so durable) case. Compatibility with all possible devices is achieved through the use of a universal USB 2.0 port, to which you connect the cable from your smartphone, tablet, MP3 player, camera, and any other device that supports USB charging.
The principle of operation is simple: first you charge the PowerBank itself from a 220V network (you can also via USB from a computer, but from the network it will be much faster), then connect your smartphone or tablet to the battery with a cable. PowerBank begins to release accumulated energy to the connected device. At the end you get a charged smartphone/tablet.
There is an even less common modification - the so-called battery cases. They put on the device and also perform protective function. But they have a big disadvantage, in my opinion - they are made only for a specific smartphone model, and are more expensive than their portable counterparts.
Advice: Do not buy very cheap PowerBanks. As a rule, they not only do not correspond to the capacity stated on the packaging, but are also very poorly assembled. This means their lifespan will be very short.
How to choose the right external battery for phones or smartphones?
In order not to waste your money and buy a good PowerBank, you need to be guided by the three main characteristics of these devices when choosing.
Total battery capacity
Most important parameter, which determines the battery life from one charge. The larger the capacity, the more energy the rechargeable device will receive. Capacity is measured in milliamp-hours (mAh, mAh), and is indicated both on the packaging and on the PowerBank itself.
Advice: for comfortable use, the capacity of the external power source should be at least twice the capacity of the battery in your device.
For example, at Samsung Galaxy S5 battery with a capacity of 2800 mAh. Accordingly, for this device you should choose a PowerBank with a capacity of 5600 mAh and higher. This way you are guaranteed to get 1-1.5 full charges of your smartphone.
If you have not only a smartphone, but also a tablet, you need to focus on the total capacity. For example, a smartphone is 2000 mAh, a tablet is 4400 mAh. The total capacity is 6400 mAh, which means the capacity of the external battery must be at least 10000 mAh.
Current supplied to the USB connector
As a rule, this parameter is indicated on the included charger for your device. For smartphones, players, and cameras, the standard current is one ampere (1A), for tablets - 2A. This does not mean that you cannot charge your smartphone from a 2-amp connector. You can, charging will even happen faster. But it is better to follow the manufacturer’s recommendations to avoid device failure.
Advice: When choosing an external battery, give preference to one with a current of 2A. Even if you don't have a tablet now, that doesn't mean you won't have one in, say, 3 months.
There are some models that have 2 located on the body at once USB connector: one for 1A, the second for 2A, respectively. If you find such an option, and the build quality/manufacturer is not of concern, feel free to buy it.
Size, weight, appearance
Everything is simple here. The larger the battery capacity, the greater its weight and size. Choose PowerBank for your use case. If you need additional power only periodically, for example, in urban conditions, or if you forgot to charge your smartphone before leaving home, then a battery of 2-5 thousand mAh should be enough for you (depending on the capacity of the smartphone’s battery). If you travel regularly, carry your entire fleet of gadgets with you, and actively use resource-intensive applications, then we recommend paying attention to energy monsters from 10,000 mAh and above.
Advice: Do not believe the claimed high battery capacity in a device with compact dimensions. This, of course, is science fiction, and you will simply be wasting your money.
Portable batteries have many more additional features: built-in flashlight, solar charging panel, protected case, etc. These “buns” are not so necessary for everyday use, but you will have to pay a lot extra for them. Therefore, pay attention to their presence only if you cannot live without them.
What is the minimum cost of a good PowerBank, or how not to lose money?
The cost of any product consists of the cost of components, the cost of assembly and packaging, logistics, manufacturer’s margin and seller’s margin. External batteries are no exception. The average cost of a factory PowerBank is +/- $20. Let’s add here the costs of logistics and the seller’s interest, and we get a price tag of $40. Of course, there are much more expensive examples, but $40 - average cost high-quality external battery.
Advice Note: When ordering a battery from eBay, AliExpress, or other similar international marketplaces, do not be tempted to buy a 20,000 mAh battery for $19.99. This is 100% deception. If you're lucky, there will be about 5000 mAh. The same applies to manufacturers unknown to you and famous brands at a very low price.

People managed to somehow not be late for meetings and, in general, meet! Now it is difficult to imagine how this is possible without communication via smartphone.
He has become so integrated into our lives and accompanies us everywhere. Sometimes solving some problems without it is not possible. Let's say terrain orientation. They cleverly help out with this Google maps. What about a calculator that is always at hand? Application for monitoring health, weight and so on.
People have become too spoiled by technology. When the phone dies, they feel helpless in this world. To avoid this situation, you must have a portable battery with you. Otherwise it is called Power Bank.
A great thing that will save everyone when their battery is running low. will become less tedious if you have a working gadget at hand. With it you can read, listen to music, play games.

So, this product will be useful to everyone. It will not take up much space, but will bring many conveniences.
How to choose a portable battery for a smartphone
The acquisition of this device makes life much easier for modern people. But so that it does not lose its properties within a month, you should take a high-quality model. Therefore, I will help beginners who do not understand electronics not to “miss” with their purchase.
How not to make a mistake with your choice and what to pay attention to?
Battery capacity
One of the important factors in choosing a device is the capacity, which is expressed in milliamps per hour. You should pay attention to the fact that the capacity of the external battery must be greater than the battery of the gadget being charged (about three times). This is logical if you want to use the charging device repeatedly. Usually the capacity of the Power Bank does not match the specified value. That is, it will not be 100% effective. If it says 5,000 mAh, you will not be able to fully charge your smartphone (2,500 mAh) twice.
For small gadgets, a product up to 10 thousand mAh is suitable.
By carefully studying this information, you will understand which portable battery to choose for your smartphone.
The main thing is not to be fooled by the low price. You need to adequately assess the situation and understand that a “powerful” device for little money is unlikely to meet your expectations.
Current strength
When the smartphone battery is low, every user wants it to charge faster. The speed of the process directly depends on the current strength, which is expressed in Amperes (A).
As a rule, smartphones require 1 A. This is what you need to take into account when choosing an external battery. Some models have two USB ports of 1 and 2 A. This option will have a larger volume. Of course, its price will be appropriate.
If the current strength of the power bank is less than that required for a smartphone, then charging will take much longer.
Otherwise, when the current strength is greater than the required value, the smartphone is not at risk. No need to worry about this. Mobile phones have built-in protection that will limit the incoming current to a suitable value. That is, nothing bad will happen to the gadget. But it won’t charge faster either.
Some users choose a Power Bank with one input to save money. This is, let's say, irrational.
But often the “native” charger, powered from an outlet, charges the gadget faster than an external battery. Why is this happening? Surely, your phone has a fast charging function. Then you need to find a product model that supports the same technology.
There are universal power banks. According to the manufacturer, they independently determine the brand of the phone when connected and select the appropriate technology. Whether this is true or just another marketing ploy is difficult to say with complete certainty.
Weight and size
The above parameters will let you know which portable battery to choose. But for many, its weight and design are no less important.
The imagination of manufacturers is so vast that you can find a whole range of different Power Banks on store shelves. From large-sized models that will charge a smartphone five times, to miniature ones that can prolong the battery life for a short time. In addition, their colors are suitable for every taste and color. From bright and eye-catching images to calm, traditional tones.
In addition, the product differs in its shape. A particularly practical option is a charging case. It does not take up much space and does not require wires for operation. For some users, this type is much more convenient than traditional power banks. But the fact is that the phone, being in such a case, does not fit so comfortably in the hand. Therefore, this option attracts few.
Additional functions
At this point, the preferences of many users differ. Some people love minimalism. They don’t need anything other than the basic property of the product. Others, on the contrary, want to combine everything in one. What's better? It’s not bad if the selected portable charging model is satisfactory in terms of characteristics and has some useful bells and whistles.
For example, an easy-to-use model that shows the remaining charge using a special indicator. In addition, a flashlight may be useful. In the dark, the battery will not only charge your smartphone, but also illuminate the way.
Another added benefit is the cable comes with different adapters. The fact is that the charging sockets of phones are different. And such a device will become a universal option.
In addition, pay attention to how the device itself is charged. The MicroUSB port will allow you to replenish its energy using a regular smartphone charger. But there are also options with built-in solar panels. However, their effectiveness is in doubt.
The main thing is not to look for a device that combines all possible functions and is inexpensive. As a rule, it is of low quality.
Best models Power Bank
An excellent choice for lovers of rigor. Stylish black design, ultra-thin body will suit everyone's taste. The battery has a capacity of 10,000 mAh. In addition, it has two inputs for charging gadgets with different current strengths of 1 and 2 A. The device can easily fit into your bag. And if necessary, it will charge not only your smartphone, but also your friend’s gadget.
A small external battery (3,000 mAh) will perfectly help you out at school or work. If your smartphone dies at the end of the day and you need to make an important call, this thing will save you. This Power Bank has one USB port. The interesting shape of the product is presented in traditional black and white colors. A good and economical option for people who are not travelers and are not constantly on the move.
Price: 650 - 737 rub.
Power Bank with a high capacity of 20,000 mAh. That is, it will easily replenish the battery of your smartphone several times without requiring additional recharging.

An excellent choice in a stylish and comfortable metal case. Two USB ports and accelerated charging will allow you to quickly “reanimate” two smartphones at the same time. In addition, the capacity of this model is 10,000 mAh. By double pressing the power button, you can safely charge small gadgets. For example, bluetooth headsets, fitness bracelets. You can be sure of the originality of the product. The label on the package has a security code. To check, you should enter it on the manufacturer’s official website.
The sophisticated matte design attracts the attention of every buyer. The slim design allows you to carry a portable charger in your pocket. Its capacity is 20,000 mAh. There is an electronic display showing the charge. The product has inputs for charging two smartphones at the same time. A great additional feature is the built-in flashlight.
Where can I buy
Today, there are more than four thousand different models of this device in the country. The buyer is able to choose it not only according to the necessary characteristics, but also to his taste and color. Digital equipment stores offer a wide range of products. You just need to walk to a large supermarket that sells electronics. However, as you know, their prices are quite high.
Do you want to make your purchase more profitable? Trusted online stores that I recommend will help with this:
With their help, it will not take time to find a retail outlet, as well as a consultant who will hardly describe each model in detail. You will have the opportunity to independently study the characteristics of any option. And then you will give preference to one of them. And most importantly, time and money will be saved.
Remember, before ordering, you should carefully read the reviews and ratings of the product and the seller.
Conclusion
Friends, today it is very important for each of us to always be in touch. To prevent your phone from leaving you at the most inconvenient moment, you should have a Power Bank with you. It will provide you with battery charging without an outlet.
You already know how to choose it so that the price-quality ratio is at the level.
Pay special attention to the characteristics of the product.
This item, like any other electronics, must be chosen responsibly. First of all, focus on battery capacity and amperage. These are the most important points. To make the item more convenient, look for a model with the additional features you need. Appearance leave the goods for later. This is the last criterion from which to build. If several devices suit you according to their characteristics, then stop at the one that suits you best.
The main thing is not to forget that a compact model with a declared large capacity, many additional functions and a low price will not meet your expectations. A good option does not mean the most expensive. You should focus on the average cost - 1,000 rubles. Products for such a price are often of quite good quality.
Approach your choice with all seriousness. And then the purchased item will bring only convenience and will last as long as possible.
