How many full phone charges for a Galaxy S22+ can the Nitecore NB ultra lightweight power bank do?

A Galaxy S22+ has a 4500mAh battery and the Nitecore NB10000 powerbank has a capacity of 10000mAh.

This means that you should be able to fully charge your phone more than 2 times.

Dividing the capacity of your powerbank by the capacity of the device you want to charge (in this case around 2.2) gives you the approximate number of charges but there is always some lose.
