Wanted to buy a second AC adapter for my iPhone 4. Since for most no-name power supply bad reviews give, I opted for this original Apple product! But the cable does not fit (USB side) into the adapter, can be pressed by force into the adapter. For subsequent connection on the network of charging does not start! Did the cable connected to the PC: recognized connection and battery is charging. Connect the cable to the adapter At repeated attempt when unplugging the cable part of the USB connector is broken from the adapter! Conclusion normal USB plug does not fit into the supplied adapter. Possibly Individual cases. But is a genuine Apple product (or good fake). After all cables and adapters have the same names as in my original. I'm really disappointed! Perhaps the replacement is better!
