It came with a wiring diagram and connectors, but I needed to supply the wires myself. I set it up in my pontoon boat. I had to make my own mounting plate. To use the screw holes on the provided plate, you'll need to cut a really accurate hole. Would definitely purchase this again.

I installed two of these in the two cars I own because I need several outlets. They're performing really well, and I appreciate being able to check the voltage of the electrical system. You need to switch them on to get them working and off to stop the voltage display. I'm quite satisfied with them, and I've been using them for about a year without any problems.

I was looking for a volt meter, USB ports, and 12-volt outlets for my UTV. Getting all these in one panel was cheaper than buying them separately. What a great deal!

I'm really like this simple setup. I built a table for my RV and incorporated this into the design. It's great because it has a switch to turn it off. The other features include a 12V cigarette lighter socket, a USB charging port, and a voltmeter to keep an eye on your battery charge. It works wonderfully and has a nice subtle blue light. If you've got an older boat, RV, or similar, this is a great way to modernize it. I'm getting another used RV and I plan to install another one there too. The installation just needs basic 12V electrical tools and cables. It can be a bit tight to work with at the back, but it's doable.

I really enjoy how straightforward it is to set up and use. I put them in an older RV. The only issue is the bright blue light in the bedroom, which can be a bit much when you're trying to sleep. You might want to consider that when choosing where to put it.

Just put this in my 2006 camper. The USB charger is fast, and the 12v cigarette lighter works wonderfully. I also glad that the on/off switch and the voltmeter. What you should aware is when it comes with all the necessary crimp connectors, but you'll need to provide the wire. You'll have to pre-wire all four parts of the panel to your 12v power source. But don't worry, really easy stuff!
