Customer Review

In decriptif article:
"Its 2 USB ports can charge two devices simultaneously and deliver a maximum power of 2100 mAh each"
It is clear yet, but the tension is not the same on the 2 outputs.
By connecting my laptop to output A with a fairly intensive application (Waze) and nothing on the B, the charge is just enough to keep the keep the same percentage. Output A works well, but with a lower power.
If I switch on the output B, the charge is much more powerful, and I get to 100% in less than 1 hour.

At this price, I will not return, but I am disappointed.
