Hi,

I bought this Bush & Müller E-werk to charge my phone while I ride. This is quite important when riding long distances, specially if you don't know the way and has to route.

The manual (http://www.peterwhitecycles.com/down...ERK-Manual.PDF) says to configure it with 4.9V and 0.5A for USB devices.

I've no idea about those things, but on my AC charger says that the output is 5V-2.0A.


With 4.9V-0.5A it charges my phone when I have it on airplane mode and with screen off. Any other configuration, the power is not enough to charge the phone.

The E-werk configuration goes until 1.5A. Will I harm my phone if I configure it to 4.9V-1.5A?
Maybe with this configuration, I can charge it with the screen and internet on (which would be perfect to route the way on my trips).
