If you are thinking of buying a power bank, this is a guide to buying portable batteries to charge your cell phone on what to look at when choosing one with some interesting models.

One of the fundamental characteristics when choosing a power bank is its capacity, a parameter that is measured in mAh or milliampere-hours. A quick count may lead us to think that if our phone battery is 3,000 mAh and we buy a 6,000 mAh battery we will be able to charge it twice. Big mistake.

The theoretical mAh provided by the manufacturer does not correspond to reality because of the contribution of factors such as the efficiency of the device itself or the operating temperature. In addition, as is also the case with smartphone batteries, batteries have a finite life cycle. That is, they will progressively lose capacity.

A good estimate of its real capacity is to approximate it to 60-70% of its theoretical capacity. We will have to multiply by 0.65 the value specified by the manufacturer. Thus, if a power bank has a capacity of 10,000 mAh and a performance of 65%, you will be able to charge a 3,000 mAh phone a little more than twice.
