How to choose a portable battery. Comparison and selection of an external battery: selection criteria, recommendations, tips. External battery - what types are there, what to look for

Everyone calls this item differently, but they miss it just as much when the battery is low and there is no outlet nearby. The arsenal of gadgets is now not limited to the smartphone; it often comes with wireless headphones, smart watches, fitness bracelets, Bluetooth speakers... For their owners, the question of how to feed this entire menagerie is especially acute. We'll 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?

We need to start by answering exactly this question: after all, an amateur climber shooting with a GoPro camera and editing video on a tablet while mountain hiking 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 these 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 advisable to multiply this number by another 20 percent to compensate for losses from heating, the influence of low temperatures outside and other factors. That turns out to be 5000 mAh.

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

In general, portable chargers are divided into five categories.

Such chargers are a chic addition to a car’s glove compartment, 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 more charge to your smartphone or power up your action camera. You can choose a compact charger based on your design preferences, and it is not at all necessary to study the characteristics of the output current: often the actual output current is 1 A, which means the charging time will be about three hours.

The power bank can be safely charged for future use so that it is kept just in case. The self-discharge of such devices is very slow, within a year your portable accumulator It will only drop by 10-15 percent.

Workers for every day

How to calculate: capacity about 5000 mAh

These everyday chargers are most often found in the hands of passers-by and in the car interior, where it is possible to recharge the battery from the cigarette lighter. Convenient, compact and effective 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 from 2.1 A, and also give preference - the coolest battery cells are shaped like thick batteries.

If you are a gadget addict and pay for purchases in the store not even with a smartphone, but with a watch, your collection of equipment can be fed with more powerful chargers. This capacitive group has a strong output current, and even accelerated charging technologies, so the design and number of ports for simultaneous recharge become the determining factor when choosing. Please note: often the second USB output is weaker than the first, so we recommend that you check this parameter in the specifications.

Ttec Powerslim 10,000 mAh with a current of 2.1 A

Accelerated charging technology significantly reduces the time to reach the cherished 100 percent on a smartphone battery. An hour, a maximum of one and a half - and the phone is completely ready for use. However, pay attention to what accelerated charging technology your gadget supports. QuickCharge, SuperCharge, Adaptive Fast Charging - all this different types, which are not compatible with each other. Thus, the smartphone can be quickly charged using SuperCharge (if it is Huawei P10), and Power Bank support QuickCharge. In this case, you will be able to power the gadget, but the charging time will be normal.

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

Wireless portable chargers

Apply your smartphone and see

More and more new smartphones are equipped with wireless charging modules of the Qi standard and analogues - for example, Samsung Galaxy S7, S8, iPhone 8, X. Just put these smartphones on wireless charging, and the battery will start charging automatically. No wires or confusion, because the technology is based on magnetic induction. Most of the smartphones that support wireless charging operate 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 capacity reserve in order to compensate for the loss of energy for such an effective transfer process. By the way, such chargers themselves can be charged from stationary platforms.

Instead of output

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

Contrary to popular belief, Power Bank does not damage the smartphone battery. Simply 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 charging cycles, which is limited for each battery.

Briefly about the main thing No need to purchase external battery from a well-known brand, since it is no different in reliability and performance from models from lesser-known manufacturers. That is why we chose the most affordable devices that will never let the user down.

Best power bank with flashlight If it is important for you to purchase a model with a flashlight, but so that it also has high technical performance, then you can give preference. Although its battery capacity is slightly smaller than that of the Xiaomi model.

Modern people prefer to use smartphones instead of tablets and laptops because they are just as productive and at the same time more compact. But due to their small dimensions, their time is reduced. battery life: It is impossible to install a high-capacity battery in a small case.

To solve the problems that arise due to this, you can purchase an external battery for your phone. You will learn in the article how to choose, what characteristics to pay attention to and which models are the most popular today.

Why is it needed?

An external battery (another name for Power Bank) is designed to charge a smartphone or other mobile device if there is no access to power supply networks. To do this, the device is connected to a mobile gadget using a special adapter cable.

Using a second battery to replace the main one is not always convenient. In addition, many modern flagship smartphones have a die-cast case in which the battery is non-removable. In this case, using a Power Bank is the best option.

Principle of operation

An external battery is a set of batteries interconnected and enclosed in a case that has a universal output (usually a USB port) for connecting an adapter. The case is made from plastic (cheap models) or aluminum.

After connecting the smartphone to the Power Bank, the standard charging process will begin. These steps can be repeated until the external battery is completely discharged. Due to the fact that it has a large capacity, you can simultaneously or alternately charge two or more gadgets, or one mobile device several times in a row.

Characteristics

When choosing an external battery for your smartphone, pay attention to the main characteristics that will help you choose a high-quality and durable device.

Capacity

This is the main characteristic that determines the performance of an external battery. It shows how long the device will provide the mobile gadget with energy.

This parameter is measured in ampere hours (Ah) or milliamp hours (mAh). In order for a Power Bank to work effectively and not cause any problems with it, its volume must be at least 2 times the battery capacity of the device it charges. But the larger this parameter, the better.

The larger the capacity of the external battery, the longer its operating period. But this increases the recharging time.

In addition, it is worth considering that the larger the capacity of the selected device, the more expensive it will be. The golden mean is 6000 mAh models. A Power Bank with a capacity of 15,000 mAh or more is suitable for charging a smartphone or even a tablet.

Current strength

The strength of the outgoing current affects the charging time of the device. The higher it is, the faster the smartphone will charge. For a mobile phone, the standard indicator is 800-1200 mA, for tablets 1500-2000 mA.

Good to know! It is advisable that this parameter coincide with the recommendations of the smartphone or tablet manufacturer.

Dimensions

Please note that the greater the capacity of the external battery, the larger it is, because more batteries are placed inside. But in this case, everyone chooses a model for themselves depending on the requirements that they place on it.

For fans of hiking, a Power Bank with large capacity and dimensions is suitable. And for users who recharge their smartphone in order to “sit” in in social networks A compact and less capacious option is suitable.

Avoid buying models that offer large capacity in a compact package. These are tricks that are used to increase sales.

Peculiarities

Different Power Bank models may have their own characteristics.

Number of slots. Some models have several sockets for simultaneously connecting two or more gadgets. In most cases, they have different output current strengths: 1000 and 2000 mA for charging smartphones and tablets, respectively.
Cable with adapter set. Such devices are suitable for new as well as old smartphones that use connectors other than Micro-USB or USB Type-C.
External battery charging method. When buying an external battery, choose a model that charges via a Micro-USB socket. This will allow you to use a regular Charger from a smartphone.
There are Power Bank models with solar panels installed on the body. Basically, they compensate for the effect of self-charging of batteries, but they are not suitable for fully charging the external battery itself.
Battery level indication. The indicator will tell you how much energy is left in the external battery and when it needs to be connected to the network for charging. This is a convenient option, but it affects the cost of the model.

The best choice

The best choice!

The main advantage of the model is excellent quality, high reliability and affordable cost. Thanks to the metal case and large battery capacity, you can easily charge the same gadget several times in a row (5 times or more).

The presence of two USB ports allows you to simultaneously charge several devices, but their close location will not allow you to connect two massive plugs at the same time. In general, this is where the disadvantages of the model end, so it is best choice for purchase.

In addition, the Power Bank comes with a charger and adapters for iPhone.

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? important point due to 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 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 port 2.0, 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 are put on the device and also perform a protective function. But they have a big, as for me, minus - they are made only under specific model smartphones, 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

The most important parameter that determines the lifespan of a battery on a single 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: container for comfortable use external source The power supply must be at least twice the capacity of the battery in your device.

For example, the Samsung Galaxy S5 has a 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.

Every year new smartphones appear, more and more powerful and voracious. Innovations in the field of batteries are not yet expected, which means that a power bank (power bank, external battery, portable battery) remains the only solution for those who often live far from outlets.

What are the differences between external batteries?

Portable power supplies, unlike smartphones and other types of advanced technology, cannot boast of much variety. And this is quite logical. Batteries - they are batteries, but you still need to know something about them.

Capacity and related dimensions

The most important parameter of an external battery is its capacity, which the manufacturer usually indicates in milliamp-hours (mAh). Roughly speaking, this is the amount of energy that a battery can store (but not transmit).

Please note: due to the fundamental laws of physics, no external battery can transfer 100% of the stored energy and no smartphone can fully absorb the energy received. Part of the resource is always lost during voltage conversion, and a certain amount goes into heat.

On average, total losses range from 30 to 40%, although some (and usually more expensive) models of external batteries and smartphones can boast efficiency of about 90%.

Thus, it is incorrect to determine the number of possible charges of a smartphone with a known capacity of the built-in battery from a power bank with a known capacity using simple division. The loss factor must be taken into account. Moreover, for reinsurance, it is better to take it at the upper limit, that is, at least 35%.

To put it simply, a power bank with a declared capacity of 10,000 mAh will in practice transfer approximately 7,500 real mAh, which means it will fully charge a smartphone with a battery with a capacity of 2,500 mAh not four times, but only three.

Please note that the above calculation is a very average and quite optimistic. You can only check the real losses when charging a specific smartphone from a specific external battery in practice.

In addition, physics requires a direct relationship between the capacity and mass of the power bank. To store more energy, the battery must be heavier and larger.

Connectors

The vast majority of external batteries, and especially those, are sold without cables. It is assumed that you will use the cord that came with your smartphone. Accordingly, the connectors on the battery and cable must match.

It may seem that you don't need to pay attention to connectors because all smartphones have the same wire with standard full-length USB on one end and microUSB on the other, but this is not so.

For example, the included Nexus 5X cable has USB-C on both sides. And in order not to buy additional wires, you will have to look for an external battery with just such a connector, both output and input, or purchase an adapter.

Kanex GoPower Slim Aluminum USB-C

Some manufacturers, such as Motorola, include a plug with a permanent cord in the package of certain smartphone models. In this case, purchasing an additional cable is inevitable.

There are power banks with a built-in cable. In this case, it is important to make sure that the connector fits your smartphone.

EasyAcc iChoc 5,000 mAh Ultra Slim

External battery current output and fast charging

The external battery charges the smartphone, which is great. Even better if he does it quickly, right? The charging speed depends on many parameters, but the determining factor is the output current of the power bank. It must be no less than that provided by the smartphone manufacturer.

It’s easy to find out the optimal amperage for your smartphone. Take the plug that came with the device and look at the OUTPUT value.

Output current

It will say something like 5 V - 2 A. You need the number next to A because current is measured in amperes.

You can find out the output current of the power bank in the description or instructions. If an external battery has more than one output connector, the current strength is sometimes indicated directly on the case next to each connector.

HP 7,600 mAh Power Pack Slim Portable

If you have two or more connectors, remember that the total current output of the power bank is limited. For example, a battery may have two outputs of 2.5 A each, but produce no more than 4 A in total. Accordingly, when two devices are connected at once, each of them can receive no more than 2 A.

If the output current of the external battery is less than that for which the smartphone is designed (for example, 1 A for a power bank and 1.5 A for a smartphone), then charging will still occur, but noticeably slower.

There is no need to be afraid if the output current of the external battery is higher than that for which the mobile device is designed (for example, 2 A for a power bank and 1 A for a smartphone). Mobile devices have built-in protections that limit the amount of incoming current to an acceptable value. Simply put, your smartphone will not explode or melt.

For the same reason, your mobile device will not charge faster if you use a plug or power bank with an output current higher than that provided by the manufacturer.

Let's say you find an external battery with a suitable output current, but the supplied plug still charges the smartphone faster. What's the matter? Most likely, your smartphone supports some kind of accelerated charging technology like Quick Charge 3.0, Quick Charge 4.0, or an option with its own name from a specific manufacturer (for example, mCharge from Meizu). Look for a power bank that is compatible with the fast charging technology used in your smartphone.

Now power banks with smart fast charging technologies like PowerIQ are gaining popularity. In theory, they recognize the device connected to them and supply the optimal current for it, but in practice this does not always work and not with all smartphone models.

External battery input current

No matter how capacious an external battery you buy, its own energy reserve will sooner or later be exhausted. It’s nice when a power bank quickly charges a smartphone, but it’s even nicer if it charges quickly itself.

The charging speed of a power bank is determined by its input current, voltage and the presence of one or another technology that ensures more rapid replenishment of its own charge. There are now external batteries that can be fully charged in less than 30 minutes.

Please note: the power bank's own charging speed does not affect the speed at which it charges the smartphone.

But lack of understanding of technology and gaps in English knowledge can mislead the user. For example, you see a power bank that says something like 5 minutes charge. You might think that this miracle device charges your smartphone in 5 minutes, but in reality everything is different.

Let's say the capacity of a particular battery is 10,000 mAh and it is fully charged in 20 minutes. In this case, in 5 minutes it will replenish approximately 2,500 mAh. And this charge is really enough to charge a typical smartphone.

The problem is that the charging time of a smartphone is limited by its own maximum input current and the availability of support for one or another fast charging technology.

Simply put, the pretentious phrase 5 minutes charge actually means: “This power bank only needs 5 minutes to get the charge necessary to further fully charge the smartphone.” Don't get caught up in marketing hoaxes and improve your technical literacy.
