Customer Reviews for Renogy - 12V 40A DC to DC Battery Charger - Black

Finally! Finally I have power while I drive going to my RV battery. I have always relied on just solar but that’s not always a guarantee. Easy install, added a on/off switch so I can turn off the vehicle 12v so it turns off if I want. Thanks Renogy

Much faster charging for our truck camper batteries than the stock trailer plug.

I bought this a month ago but just installed it this weekend. Everything went well and I’m very pleased so far. After redoing the wiring on both my truck and 5fr things looks good. Updated my alternator on my 2003 Dodge Ram 3500 diesel from 130amps to 180amp. I did a direct hookup to my battery’s and ran 4 gauge awg welding wire to 175 amp Anderson type connectors. Tested and all was good. Got 40 amp at my Renogy battery bank. Turned the power off from shore power and let my battery’s go down till morning. Hooked it to my truck and all began to charge well even at idle. Will update after the first of the year as we’re planned to go camping during Christmas. Merry Christmas to all.

Bought a month ago and so far it works great. Just what I needed to keep my secondary battery charge on my truck and topped off.

Bought this and a 200ah agm a month ago, a real lifesaver in this case. I work construction very remotely and sleep in a van. After a failure of another brand of solar power station I needed something to run my diesel heater at night. This was shipped very fast and does its job flawlessly. I’ll definitely by buying more renogy products!
