BlueFire Upgraded Aluminum Alloy Quick Charge 3.0 USB Car Charger Socket & 2.4A USB Port IP66 Waterproof Dual USB Power Outlet with Voltmeter for Car Boat Marine Rv Motorcycle (Red)

Purchased to hide a voltmeter and smart phone charger in the ash tray of my green 1970 Nova. Then my John Deere charging system /battery started going weird. There is a factory knockout in the dash of my JD D110. Drilled a round hole in that location and it fit perfect with view from the seat, the PTO lever cleared when devices plugged in and the charging location works well with a long cord drapped over to the fender pocket. Wired into the yellow ignition on wire and it's a great way to monitor the battery, alternator output and add device charging. Will be buying more for my boat and Nova. Hopefully won't get stuck on the lake or side of the road from running the battery down too far.

This is a pretty neat USB power/voltmeter. I installed it on a sport touring motorcycle, and so far am pretty happy with it.It appears to match the bike's own voltmeter pretty close, though it reads .1 below. A difference that small could be attributed to the wiring, etc, so I'd call it close enough.Upon opening the box, I was annoyed that it looked like the wrong part, as the black plastic cover doesn't look transparent. But I stuck it on 12v, and the voltage reading lit up and became visible beneath the plastic.I like this more than I'd expected, because it basically hides the meter when the bike is off. Not that it would be a huge difference either way, but less busy-ness is always good to me.So if you open the box and think they sent you the version *without* the volt meter, give it power before getting annoyed.Side note...you might wonder why I'd want an outboard digital voltmeter if the bike already has a factory digital one; well, this one is immediately visible at a glance, while my factory meter is on a screen I have to scroll to. Not super important, but I've been broken down enough that I like to keep an eye on as many parameters as possible.Update: with both ports now connected, the meter is pretty hard to see. It would be better if the meter were on top and both USB ports beneath, but that probably wouldn't fit the circular limitations.

Just installed so not much to say on performance but it was easy. NOTE, when connecting it to positive negative wires, the silver is positive and copper is negative. Backwards from how housing outlets are. One way works, the other doesn't so it was easy to figure out.

this functions exactly as it should, voltimeter is acurate against a multimeter, installed it in a marine application so the access plug is greatly appreciated

Lawn tractor, charge phone and action cam. Does what I needed.

Quick and easy install , piggy-backed it off the existing cigarette lighter port in my 1999 Land Rover discovery 1 . Ultra fast charging as advertised!

Easy to install, plus que quick charge really does a quick charge, installed it in a 2002 Toyota Corolla S. (Requires to remove dashboard or console during installation but do a worthy one if you are tired of using and adapter).

If you are looking for a fast charging USB port this is the one to buy. It's built extremely well and the machined aluminum looks amazing. Installation was easy if you know what you are doing and the precrimped connection and wiring was plenty long enough to tap into my existing wiring harness for power. The built-in meter works well to keep an eye on your cars battery condition as well. I will definitely be ordering more for my other vehicles as well.
