You even posted in the other thread near the top. No need to rehash or have multiple threads on the same subject especially when most AC adapters designed to accept a standard USB cable and produce 5volts will work. Not to mention that most cellular phone AC adapters designed for 5volts with a micro-USB connector will also work, excepting oddball companies like Apple.
