I've been using this switch panel in my overland trailer for half a year now. I knew from the start that I'd have to redo the wiring. I didn't want the panel on a single master switch and I wasn't keen on having the voltmeter and USB ports always on, so I used the panel's switches to control them. Here are some problems I've encountered with the panel: One of the two USB ports seems to have failed quickly, or maybe it was never working. The 12V DC socket isn't sturdy enough to hold plugs in place. The voltage meter isn't as precise as other ones I've tried. I was happy that the company (Kohree) contacted me about the issues with the panel. They sent a replacement, which I tested right away. All the plugs (DC and USB) are working fine on the new one. The 12V DC socket still isn't as firm with plugs, but the panel now comes pre-wired with the USB ports, voltmeter, and DC socket controlled by a single switch. That's a nice improvement. Props to Kohree for their proactive customer service. PRO TIP: Test all the switches and ports on your panel as soon as you get it, even if you're not installing it right away. If there are any issues, contact the seller - they're very quick to respond.

It's been working really well so far. I've got it set up in a custom panel for my racing car. It's handling my fuel pump and the fans, and soon I'll be hooking up the LEDs and gauges too. It seems to handle humidity and moisture just fine. I'll let you know if there are any issues, but for now, it's a solid 5 out of 5 stars and I'd definitely recommend it.

I set up this gear on my ATV/snowmobile trailer that doubles as a cozy camper. I added a shelf for things like phones, wallets, and glasses, and placed the Kohree panel on it. I connected the panel to the battery box on the floor and linked the power vent and inside light to two of the switches. The wires are high quality, with each switch having its own fuse holder, and the fuses come with it. The screws they gave are really sturdy too. I drilled pilot holes with a 5/64" bit for the screws. Now, I can charge my phones in the camper, and the cool blue LED lights on the power outlets and USB ports make a great night light!

I've installed one of these in a boat and just placed an order for another one for my RV trailer. It's working fantastic and is a really good deal. I have a couple of suggestions though: 1) It would be great if you could provide a protective box for the internal wiring. Both times I installed it, the wires were at risk of getting damaged or pulled out. 2) Throw in some RV-specific labels. The ones that come with it are all about boats, so I had to make my own labels for the RV.

This product seems solid. I just wish the button lights would stay lit or change colors when they're on or off. There are absolutely no instructions at all! You really need to be good with measurements and wiring to set it up.

This setup is great but a bit bulky. I took it apart and used the pieces for different things. The switches and outlets are really well made. It arrived super quick, was easy to install, and totally what I needed!
