I installed this into an Overland Suburban build I'm working on ONLY after testing it thoroughly. I have found this convertor to work perfectly and work perfectly on a 40amp load. I am so confident in this item that it's being permanently installed in my Burb for this upcoming season.Highly Recommended.

Rated 4 out of 5 stars because the terminal connectors feel cheaply placed, there isn’t a support under the motherboard that links the terminal connectors, so it’s kind of flimsy. Overall the fan is pretty quiet, charges my 180AH lifepo4 battery.

The unit looked like it had experienced some kind of malfunction. I pulled the cover and didn’t see any signs of damage, so I installed it. It doesn’t work. The holes for the screws were also too close so I had to use my Dremel tool to grind some material away. Very unhappy and inconvenienced at this point.

This was the same model that I had to replace.

I added lithium batteries to my class C RV and needed to replace the dead battery charger. This one is rated higher than the original and therefore didn’t fit in the old spot but there was plenty of room elsewhere to mount it. It keeps my batteries nicely charged. No complaints.

This power supply would not go into the Bulk mode. It was set st 13.6 volts only.

Solid construction with good case components.Outgoing power connectors are robust, will hold up to reasonable usage.There are two 40 amp ATC fuses protecting the outgoing side and protect charger against reverse polarity.Power feed is a standard USA 120 VAC grounded outlet. 11 amps load is within range of majority of USA outlets.
