Cool voltmeter/USB port

[zman]

Maybe nothing new but new to me,would be nice for a direct and more accurate voltage reading plus USB.

I like it! I have been trying to figure out where to re-install my 2" analogue voltmeter since I pulled my Vetter faring. Just can't seem to find a place and waterproof the installation.

USB 1 amp and USB 2.1 amp both being powered by the same pos and neg, how does that work that they'd be different capacity?

They are a 12v to 5v reducer and I assume that there are 2 circuits in them. Most reducers/ car adapters that I am buying are 3+ amp but it usually means two ports of varying current output like this one.

Use charger voltmeter and thermometer

I had bought a new voltmeter like the one with the usb charger in it to replace one of my cig/accessory sockets on the Rats Nest but instead I am using this combo adaptor with alternating temp and volt readings.

Plugged in to my left hand cigarette lighter plug socket with charge lead running up to the dash mounted iphone.

After a while it scrolls to voltage then back to temp etc
