Keeppower 21700 5000mAh P5150TC (White-Blue) 2020
![]() Official specifications:
![]() This is a 21700 cell with build-in USB-C charger, the cell is a protected high capacity cell. ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() The two cells match just about perfect and can easily deliver the rated 8A. ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() The USB charging uses a switching regulator to keep the heat down, I measured about 10°C temperature increase at the front of the cell during charge. The USB-C input do not follow any protocols, except signalling it needs power. ![]() Conclusion It is a good battery and the USB charging means it can share charger with a mobile phone, this is very practical when traveling or when having only a few LiIon batteries. Only caveat is that the battery is considerable longer than a standard 21700 cell. Notes and links The batteries was supplied by Keeppower for review. How is the test done and how to read the charts How is a protected LiIon battery constructed More about button top and flat top batteries Graphical comparison to 18650 and other batteries Table with all tested LiIon batteries
