Ok, I have my E7, it charges fine hooked to the computer & to the wall charger.
I have two different style USB Car Chargers, that I have used for my N900, My old Sidekick, iPod, Bluetooth....
Niether of these Car Chargers work, I have tried mutiple USB Cables with these USB chargers & nothing..... how can they work with my N900 & other devices, but yet my E7 does nothing when I plug them in?
I use the same cable I use hooking it to my computer, and even then.. nothing, but I know both these USB car chargers function fine.
Something is wrong with the design of the phone?
E7 wont charge with Car Charger?
I will try to learn it and get back to you
