A: Micro Usb.

**Q: Can it turn on/off if plugged into a timer? (Basically I would like it to turn on for 5 minutes once an hour). Or can it be programmed for this?**

A: Return it, need the spring to enable the wick to maintain contact with the plate. Could utilise a piece of sponge to enable the necessary pressure.
