Picked up one of these "3 way USB charger with a voltmeter"

Charges/runs a bunch of stuff while mobile or at least in the truck. Not yet used it in the camper. Voltmeter seems to be fairly accurate BUT you CAN NOT see the little numbers in the daylight. Voltmeter active anytime the thing is plugged in.

Would likely be more visible in the trailer. Now you don't have to install a voltmeter if you have a 12 volt outlet (Which I had to install) :rolleyes:

$10 or $11 depending on color.

I'll now vouch for the accuracy of the little digital voltmeter.

With engine off it read 12.2 volts. A bit low. Engine running it read 14.6. A bit high. I wrote that off to being a cheap Chinese made voltmeter, which, in fact, it is.

But then the battery in my truck finally died. Replaced a rather expensive Group 65 and low and behold, engine off it reads 12.8 and engine running about 13.8. About where it should be.

Go figure.

Oh, and it does a dandy job of charging my phone while I drive. :)
