Q: Does this unit have auto shut off?
A: It seems to shut down once you remove the device you are charging. So far I have only used it with devices which were powered on during the changing cycle, so they were never "done", so I don't know if it can sense when the device being charged it full and might shut itself off. However, if you just turn it on with no load it will turn itself off after a short while.
