The battery of a smartphone or tablet always runs out at the wrong time, and not in all cases there is an outlet nearby to charge the gadget. For such situations, there are portable chargers with which you can charge your battery anywhere. How do they differ from each other, and how to choose a portable charger?
Instructions
Step 1
The most important technical characteristic for a portable charger (also called PowerBank) is its capacity. It is measured in milliampere-hours, and the more the better. If, for example, you use this device to charge your smartphone, it is desirable that the capacity of the portable battery is two to three times the capacity of your own battery of your gadget. This will allow you to fully charge your mobile phone again twice or three times, which is especially convenient when traveling.
Step 2
True, the larger the capacity of the portable charger, the more it weighs and takes up space. So, if this is what matters to you, look for a balance between compactness and milliampere-hours. For some devices, such as an mp3 player or wireless headphones, a large external battery may not be needed.
Step 3
The charging speed can also be different, it depends on the current strength. Find out how many amps you need to charge your device and do not forget about this figure when choosing a portable charger. Most modern smartphones that support the Quick Charge function require a current of 1 A or even 2 A, and if you charge them from a source with a current of 0.5 A, it will take a lot of time.
Step 4
The number of connectors on the portable charger may also matter. Suddenly you want to connect two gadgets to it at the same time, or even three!
Step 5
Some portable chargers have a solar panel that allows them to recharge while away from a wall outlet. This is an additional plus of such a device. However, do not entertain illusions: the solar battery is not able to charge it quickly. If you will be resting somewhere in nature and decide to take the opportunity to replenish the charge from the sun's rays, take care of this in advance and leave the charger in the light for a long time.
Step 6
The convenience of the indicators, the design of the case, the manufacturing company and the presence of any additional features may also be important when choosing. For example, some models have built-in flash drives, flashlights, card readers.
