All about power banks

A power bank, who does not have this in their backpack, laptop bag or precisely at their workplace? No one gets enthusiastic about a flat battery just at that important moment. When you choose to carry a power bank this will be definitely be a thing of the past.  

What is a power bank?

The power bank is an externally chargeable battery to which you can connect other equipment to then charge it. The simple and portable device is therefore very suitable for carrying in your pocket if the battery charge of your smartphone or tablet goes down quickly. With the diversity of models there are even power banks which can charge your laptop or camera, which is useful if you have forgotten the cable.

Maximum capacity of a power bank

The capacity of the power bank is decisive for the question of how often a smartphone or tablet can be charged. For an average smartphone, a power bank of 5000 mAh (milliampère-hour) is enough for about two full charges. For a tablet, you often need double that in order to charge the whole device fully at least once. For a laptop you also need a special power bank with a capacity of at least 12,500 mAh. You must take into account that a power bank with more capacity will be larger and heavier and will therefore take up more space.

Charging time of the power bank

In addition to the capacity, the charging time of the power bank plays an important role when purchasing such a battery. A power bank with more capacity of course needs more time to fully charge than a battery with less capacity. Current is also always lost by the use of an adapter. A power bank therefore easily needs 5 to 10 hours to completely charge. The power bank itself is often charged via a USB, to be connected with the power socket or the computer.

Ease of use

The ease of use of a power bank depends on various factors. Firstly, it is important to take account of the capacity: the higher it is, the larger the system will be. Carrying it in your trouser pocket will then be difficult. Secondly, you must consider the amount of USB ports. If there are several, various devices can be charged at the same time. Some models even have a pocket torch for connecting in a dark environment. Finally, power banks with a fast charger can be charged in just a few hours.
