Powering a Wi-Fi router from USB Answered
Few days ago I bought a Huawei B260a 3G Wifi Router (http://www.mobilityminded.com/6685/huawei-b260-3g-gateway-review-routing-a-cellular-data-connection). The power supply has an output of 5V/2A and is connected to the router with a USB B plug.
In my car I have a Belkin USB charger with 2,1A output. So it would be nice if I could use the router in my car.
I tried to connect the Router to a USB wall charger (5,1V/2,1A) with a standard USB A to B cable, but this didn't work. Furthermore I tried to cut the cable and connect only the black and red wires, this also didn't work.
Somebody told me that the layout of the plug is different (as far as I've seen, at least the contacts match to the standard), can this be true? And is there a possibility to realize my idea of a hotspot in my car?
Thanks for your help!
