Good question. I was following the recommendation from Aironboard to only use their dash switches with relay connections. Was also using the Garmin hardwire kit specs rather than the Mini 2 itself. Not planning to use the Garmin kit, just a single cable 3rd party kit.
Looking at specs:
- Aironboard switch is rated at 12V 3A
- Max rating for micro usb power charging looks like 5V 1.8A
- Garmin’s own hardwire kit has a max output of 5V 1.5A and input of 12V 0.8A per channel.
- Non power charging usages micro usb should top out at 5V 1A.
Seems like I should be okay directly wiring the Aironboard dash switch on the 12V side of a dash cam cable kit with a 2A fuse. That should be enough for usb power while protecting from a short that would exceed the dash switch rating.
Planning to use this switch:
