Working as advertised but found out it’s low efficiency - while delivering 57A it takes 89A from alternator. Also there is no low voltage shut down so when car slow and stop on red light and RPM are low voltage drop below 11V and car (radio lights) not functioning correctly while it still sucks all these Amps.

UPDATE: I would love to say this a great charger, however I have received two of them and neither of them worked correctly. The first one was DOA when I received it. It cost me $200 to have it installed, only to have my installer tell me it was not working correctly, and pull it out. I sent that back to Amazon, but was out the $200 installation fee. Stupidly, I bought a second one because I like the company. I again paid $200 to have this installed in my RV under the passenger seat where apparently it needs to go. This one worked, so I was happy with it. It worked well, in fact, for all of three days into my vacation, then I noticed on my battery monitor that there was no charge whatsoever coming from my alternator. On vacation, 2000 miles from home, I had to drive two hours to an RV place to have this unit taken out. Removal and reconnection of my old wiring cost me $220 this time. Now I am up to $620 in installation and removal fees. I drove the rest of my vacation with the straight alternator and was fine. When I returned I called Amazon and they agreed to take back the unit even though it was past the 30 days. They said they would charge a restocking fee but that the fee would be waived once they received the unit. They now refuse to refund the 45.00 restocking fee because the unit is not in re-sellable condition, to which I can only say, Of Course not! The long and short of it is that it cost me $665 to try to make this work and as much as I like the company, it doesn't. The units I got were defective and I would not order this again from them.

I purchased the 60 amp model. Installed in my truck cap along with an inverter and a 100 amp hr deep cell battery. I installed it to run our Ecoflow cooler, as well as to run some of my tool battery chargers. We took the cooler on our east coast trip. The cooler was plugged into the inverter the whole time for about half the trip. I had the cooler set to 38 deg F. Each morning when I went to start the truck, it turned over slower than normal. I thought that was odd. after a couple days, brought the cooler into the cabin. those mornings the truck turned over just fine. So this is not isolating from the starting battery when the truck is turned off. Did I miss read the manual? Is it not supposed to isolate from the starting battery when it is turned off? I have it hooked into the alternator wire as instructed. Now that we are home I'm going to do some testing with my amp clamp.
