Below are the power plug size for the iFly 700/720 and the smaller 12V out of the Battery. I also included the USB type as well. It's not in the manual as we don't want to promote a lot of splicing of wires. We do offer extra AC and DC cords on our store and using the wrong plug might void your warranty or damage your unit.
- iFly Unit and Battery: Power IN : 3.5mm OD x 1.35mm ID
- Battery Power OUT : 2.5mm OD x 0.65mm ID
The USB is a Host 2. It's not your typical USB port on tablets. I hope this helps.
