What is a Power Bank? 

A power bank is a portable charger designed to recharge your electronic devices when you're on the move.

Ranging in size from slim, pocket-sized devices up to larger, higher-capacity power banks ‚Äď they can be used to charge smartphones, tablets etc.¬†

Typically, the smallest power banks have a capacity of around 1,000mAh, medium-size units about 3,000 to 5,000mAh, and larger units can reach 10,000mAh or even 20,000mAh!

How Much Battery Capacity is Enough? 

In general, bigger is always better.

The bigger the battery capacity of your power bank, the longer your power bank can supply power to a device without needing to be recharged. 

As a general rule of thumb, a 20,000mAh power bank can actually charge a 5,000mAh smartphone around 2.66 times before needing a recharge itself.

This is because there is inherent inefficiency built into the charging process due to reasons such as electrical resistance in the USB cable and energy being converted from electrical energy to heat energy that is dissipated. 

Of course, this figure will vary according to your power bank or phone, so expect more recharges depending on whether you have a bigger power bank and/or a phone with a smaller battery. 

Is There a Trade-Off? 

Battery capacity almost always comes at the expense of size and portability.

Power banks with bigger battery capacities are usually bulkier/heavier.  

But there are exceptions such as the AUKEY PB-Y37 20,000mAh 65W PD Powerbank which weighs only 370g. 

Final Words 

If you're the kind who uses your device for extended periods on the move, you should get a power bank with a massive battery capacity.
