Another mini-project finished: Installed the voltmeter/USB charger. Adding this brings the # of USB charge plugs in our RV up to 12 (8 of them are 2+ Amps)--if you can't find an open spot to charge your device in our unit you aren't looking hard enough. Now I have a permanent 12V meter on the dash (looks like those plugs are connected to the chassis battery).
As a bonus the spade connectors fit the USB charger perfectly--all I had to do was unplug the 12V socket and plug in the USB charger.
Yes the Dremel made quick work of the hole but none of you mentioned the mess it would make LOL. 20,000 RPM shoots that stuff everywhere! We'll be finding black bits of plastic for a few seasons now.
