Portable battery for your phone: models, rating, tips on choosing

Why do I need a portable battery?

As already mentioned above - the battery (that is, the battery) in modern smartphones requires constant recharging. Gadgets are becoming faster, more powerful, more, and in terms of autonomy, almost nothing changes. The average battery life today rarely reaches 8 hours or more, under a serious load, this value is reduced to 5 hours. And even if struggling to stretch the available capacity, to achieve autonomy at least in two days is almost impossible. It sounds sad, but it is true that gadget manufacturers would not say. Naturally, the problem did not remain without a solution, and since it is not possible to significantly improve the autonomy in the gadgets themselves, an additional battery can be used. In the case of old-fashioned phones that are disassembled, having received full access to the battery, you can replace the main battery. But such phones are getting smaller, they were replaced by monolithic cases in the manner of the iPhone. An additional battery in this case is an external portable battery for the phone.

How does a portable battery work?

However obvious it may sound, the external portable battery works just like a regular (internal) battery. Changes relate to a slightly modified design in accordance with the scope of application of such a battery. In fact, this is a series of power cells that are soldered to the power controller (similar to those in smartphones). Then, ports for recharging the battery itself and one or more ports for charging smartphones, tablets, laptops and their ilk are built into this design. Despite the simplified, in comparison with the smartphone, version of the design, the battery works according to the same principles as in the phone, so the battery remains the most dangerous object in any gadget. Like any other device, an external battery has a number of characteristics that you should rely on when choosing a portable battery for your phone. How to choose the right model based on its technical equipment and what is really worth paying attention to?

Portable Battery Capacity

The main parameter that you need to pay attention to when choosing a device.It is from this indicator that how much extra time “life” your smartphone will receive, which means that in fact this figure means the efficiency of the battery as a whole. This value is directly related to the battery capacity of your smartphone. As well as the volume of other compact batteries (smartphone, tablet or smart watch), the battery capacity of an external battery is measured in ampere-hours, namely in milliampere-hours. When choosing the optimal capacity value, you first need to find out the volume of the battery of your smartphone (smartphones or tablet), and then find an external battery with a value of at least 1.5-2 times more so that you can recharge your phone (another gadget) at least once. Suppose you have a 2500 milliamp-hour battery installed on your phone. If you want to get at least one additional recharge cycle, then you should look for an external battery with a capacity of 4000-5000 milliampere hours. It would seem that this is a bust, in fact, the actual battery capacity is always different from the one declared by the manufacturer (this is especially true for solutions from China). And the device loses its charge even inactive.The best option when buying is a 6000 milliamp-hour battery for smartphones and 12,000 milliamp-hour for tablets.

Discharging current

Everything is simple: in order to share electricity with a phone or tablet, a portable battery needs a certain amount of current. Usually one amp (1A) is enough for a smartphone to fully charge. With tablets and their giant batteries, more power is needed, at least two amperes (2A). Some portable batteries are equipped with several ports from one to three amps. This option is suitable for those who plan to charge several devices of different types at once. You can find out the exact information about what kind of current is needed for your gadget by looking at the label of the charger.

Another serious point, which is often overlooked by careless buyers - a way to recharge the portable battery itself. The fact is that some models have a specific socket connection and generally only eat from a computer or laptop, which adversely affects the speed and efficiency of charging.Such devices are outdated and nowadays almost not produced, but they can still get you. It is better to make sure that the purchased gadget is equipped with a standard micro-USB port and is capable of charging from the mains.

Design, size and weight

Anything can be found in this category, manufacturers do not limit themselves to anything and often experiment. There are different variants of cases for portable batteries. Colorful, bright, catchy, big, small, with handles and without them. From giant monsters capable of charging your phone more than 6 times, to tiny ladies' batteries, capable of only briefly extending the life of a smartphone battery. External batteries vary in their form factor. For example, there are interesting solutions, made in the form of a cover for a smartphone. Thanks to these options, the user does not have to carry a cable and allocate a separate space for a portable battery. Often, massive batteries are equipped with a large number of ports, reaching up to 5 different USB ports. Such solutions are suitable for those who want to recharge several gadgets at the same time or share with a friend.There are other chips, for example: a built-in flashlight, displays with indication, straps, locks, and so on, in general, everything that the manufacturer’s imagination is enough for.

When choosing a device design, you should pay attention to two important details:

  • The on / off button must be recessed into the case so that the gadget does not accidentally turn on in the bag or in the pocket and do not begin to supply energy to nowhere;
  • The specified battery capacity must match its size; no one can shove a 12000 milliamp-hour battery into a watch-sized case.

Portable phone battery - how to choose?

Even knowing the specific specifications and features of external batteries, the question of choice remains open, since various companies are engaged in the creation of such devices. Some make batteries exclusively for specific smartphones, someone makes universal options. In some decisions, emphasis is placed on the exterior, in some on the technical aspect and reliability.

If we imagine an average solution that exactly fits all, then it should have the following characteristics:

  • Capacity is from 6000 to 12 000.
  • 1A port or several different ones at once.
  • Weight not more than 500 grams.
  • The price is about 1 000 rubles (all that is much cheaper is also much inferior in quality).

This knowledge is already quite enough to begin an independent search for a suitable battery, but still it is worthwhile to introduce specifics. Next, consider the various portable batteries for your phone. The rating of the most interesting decisions on the market that stand out for their colorful exterior, unusual design or extremely low price is presented below.
