\n\nhi, i'm new owner of Hammer S.
Charger included is very poor in terms of current.
I have measured with usb amperemether and it supply 0,5Ah ..
so the chargins is very low.. i have measured more than 6 hours necessary to fully charge.
i changed charger with the very good aukey quick charge 2 (5V 2A) and Hammer charge with about 1,3Ah and took less than 3 hours for fully charge!

if you using the smartphone during charge, 0,5A given from original supply charger is not enough to charge and you saw discharging..

Yes, thanks for tip. Tried it and it solved problem. Original charger is weak for this battery. Used old tablet charger 1.2A and it was fully recharged overnight.

so definitely bad power supply provided with Hammer S.
ask to UMI to send a good one for free!

UMI has reported this issue to the supplier. They're trying to find a solution to solve this problem.
In my opinion, that's simpler to buy another (1A) charger head.

Hi! I have the Hammer S for 1 week and every time i charged it, even a full night, it stops max to 65%.
Is it a battery or software problem?
Does anyone have the same problem?
Thanks
