Hey I got my GS2 from the UK off ebay and had it shipped to the US. I love it but I don't have a transformer to deal with the current differences and really don't want one anyway but charging this thing off a computers usb is painfully slow. I ordered an OEM charger and USB cable cable from Samsung that should get here Monday. Can I use those without having to worry about it damaging my phone because of Samsung's smart chip charging or do I need to do something else? Also will it work with any usb car charger or do I need something special for that too?
