A few minutes ago I needed to charge my iphone 4. I had the apple USB cable but not my wall adapter (sorry, I'm from Portugal and I don't master all the terms!).
I found that my eGo cigarette charger had just that missing part, just on a different collor. It seemed to me that the pecs where the same, so I tried it.
A few minutes latter I hear a click and the iphone stopped charging and a slight burn sent got in the air. The e-cigarette stoped working. Probably broke!
The question is. Do you think my iphone battery got compromised with this? I ended up charging the rest directly from the PC USB port.
PS: Specs on e-cigarette charger Input: 100 - 240V - 50/60 Hz 0.15A Output: 5V ---500mA
