I installed this in a sprinter van to charge batteries in the rear without any issue. It is in a dry environment. Didn’t really need instructions but all you need to know is which terminal is which, cause they are written in Chinese on the unit.

Stopped working months later.

I have this mounted under the rail in my truck bed for a second battery, I had an issue with battery drainage prior so when I decided to add a second battery to my setup one of these was a must. So far it has functioned flawlessly at a fraction of the price of other available units. Highly recommend.

I have two of these and they each charge two different battery banks. They work very well 24/7.

It may be too early to write a full review but so far it seems to be working correctly as described. It’s a pretty simple setup. It does cut out aux battery at about 12.7-12.8 haven’t ran it all the way down yet but I will update once I test it all the way out

The product DOES isolate the starter from the house batteries, however it frequently flashes the voltage meter whenever a load is applied.
Tried to use it to boost the dead starter battery today, no luck with that either, just flashing with very little transfer.

hooked it up exactly like it showed didn’t work. Send it back ordered one from another store. Color was black but it’s pretty obvious they’re made by the same people. Anyhow, the black one works great does exactly what is supposed to. The instructions for both are terrible, the black one had a little bit better instructions but lacked information on what the blinking light was all about. The instructions showed what the blinking light was for. So if you buy both of them, you’ll probably figure it all out unless you have a little bit of electrical background that you could do on your own.

I’ve had it for just over a year. Bought late May of 2023. Here it is end of June 2024. It worked ok at first. Alot of connecting and disconnects. I had to put a jumper wire across both terminals and a switch on the negative so that I can bypass it and force my truck to charge the batteries. If you are running a high power inverter be care as it will get hot to the touch. I’d give a 3 star rating. It works about 80% of the time. but it’s cheap Chinese materials

Good product but didn’t work like we needed it too. Sent back.
