Front USB ports

[stevedee]

I think the USB port is 20w (10v @ 2 amps) so that should be more than enough but I guess you could be right, the cabin camera add-on might be demanding too much power. I charged it up last night so I'll check it later and see if it works then.

USB ports are always 5Volts.

The 'mirror' ports are 2A, so 10W.

The rear port (back seats) is 3A, so 15W.

This info is from the User Manual. I hope this helps.
