I have a solar-charger gives 5V AC and want to connect to my Nexto M1. Please can you tell me the polary of the external power-adapter-plug? wich is +? (needed for trip) thx!
Do you have a electric tester? M1's adapter jack have a "Ground" in the outside and "+5V" in the inside. Also the M1's electric Specification for the DC adapter have a 5V/2A output to operate the M1 and be charged. If you satisfy the conditions, you can use anything.
