How to choose a power bank with fast charge?

When choosing an external battery to charge your gadgets, there are several important parameters that you need to clarify before buying such a device:

Capacity level. For power-hungry devices like a laptop, it is better to give preference to batteries with a capacity of at least 10,000 mAh. In general, the capacity should be selected based on how many full charges you may need in the intervals when the wall outlet is not available. If you usually do not go out into the countryside with tents and you do not need a supply of energy for several days, you can get by with 1-2 charges. This will be enough for you all day. If the outlet may not be available for several days, it is worth considering purchasing a model with a large supply of energy.

Output voltage. The minimum indicator sufficient to recharge the phone is 5 V. For laptops and tablets, higher ratings are required – from 9 to 20 V. In this case, be sure to keep in mind that if you charge several devices at the same time, then the power will be divided between them. That is, in most cases, if you connect two or more devices, then they will charge twice as long as one.

Number of power bank fast charging output. Most portable chargers have one connector, but if you need to charge several small devices, more are better.

Compatibility. Make sure the input voltage required to charge your digital devices matches the output voltage of the external charger model. This is an important parameter, since if the output voltage does not match, the lowest value will be taken into account.

Dimensions and weight. As a rule, powerful and capacious devices are larger and weigh more. Keep in mind that the most capacious devices will not fit in your jeans or shorts pocket. Think in advance in what you will wear the power bank in the summer.

External design. If the classic design of a power bank with laconic geometric lines seems boring to you, you can choose a battery of a more interesting shape, or in a bright color.

Additional functions. In some devices, manufacturers “hide” useful options, such as a solar battery, LED flashlight, battery level indicator, card-reader, etc.

Fast charging. Charging speed is one of the most important indicators if you plan to charge your device other than at night. The Best portable power bank for iPhone on Amazon can charge your smartphone up to 50% in about half an hour. This can be important if your smartphone is using too much power and you need to recharge it quickly throughout the day.
