A must have for towed vehicle
This battery maintainer works as advertised. I have used it for several months and 4200 miles on the towed vehicle and the battery stays charged all the time.

Needed for flat towing you vehicle behind a Motor Home
Small and easy to install direct to battery. Make sure you RV has power at its 7-way so it can charge you car.

I tested it and it works great, as advertised!
I've been using mine for 6 months now and it works great! I read several posts that claim it doesn't work, so they either got a dud, or they aren't following the proper procedure in their car manual and pulling the right fuses. My manual recommended pulling the BCM (body control module) fuse so I decided to run a test. On my first day, I pulled the fuse and towed for 6 hours and when I stopped for the night I checked my battery and it was right at 13 volts and all was fine. On my second day, I put the fuse back in and decided to check it after about 3 hours. My battery was down to 10.6 volts and this little charger was hot so I again pulled the fuse. After about 3 more hours of towing, the battery was back up to 12.6 volts and the maintainer was cool again. I also tested the output of this little charger and it puts out just about 2 amps when the battery is low. I don't know if it trickles down any farther when the battery is fully charged as I didn't bother to test that, but I do know my battery is never over 13 volts at the end of the day so it must? Bottom line, check your manual or go to your local dealership and find out which fuses to pull from your vehicle and this little guy will work great! HAPPY TOWING!

No more stopping every 2 - 3 hours hoping the car will start....
Have had this product for a couple of seasons on my motorhome now. I was about to really slam it after the first half of my last trip - since my tow battery was still dying. HOWEVER....After using a bungee to hold my wire harness in place on the motorhome - I did not have any further problems with my tow vehicle. It started up every time after that with seemingly no loss of power. Went over 4 hours in one segment and still no issue (had been less than two previously).So - I am right now optimistic that I solved my issue with why it was not working consistently (unrelated to the product), and will hopefully have a charged battery at all times going forward.Pros:Seems to be working now (not an issue with the product)Battery stays charged (Yay!!)Relatively easy to install (had to do some wiring - but not too bad if you do your homework and have done some minor wiring previously).Self contained and no additional parts neededCons:Hmmmm.....I would suggest you use a meter and confirm it is working before relying on it. If not, recheck your wiring. I found that some of the information on the web about the tow wiring harness was not always accurate...and there were variations that were not well/widely known. So do your homework and then check to make sure it is getting and giving the power needed before calling it a day.
