My powerbank has 2 outputs;
1.0A
2.1A (obviosubly I used this one)
My phone is a Samsung Galaxy S7
My phone has fast charging enabled.
My phone charges faster (fast charging) when its from a wall-socket.
I tried this;
Wall socket (fast charging) ~ 40 min
Powerbank - 61 min
What is the problem?
The USB i'm using is a 0.5m USB 2.0 to MicroUSB
Also;
I charged with the 1.0A, and it also said 61m until fully charged. So what is the problem? The powerbank? The USB?
