NPB2 Waterproof Powerbank (10,000mAh 36.4W QC3)
Just the right size and capacity between the 5k and the 20k ones ...
Fits my current needs ...
Got the 5k one which is portable enough and not too heavy in the pocket
Got the 10k one to bring along for those long trips which requires a bag; and of course backup battery juice
Still considering the 20k ones ...
