I took a risk on this as there were no Revain reviews back then. All I found was an Irish guy on YouTube who bench tested this device and smoked it. I hope I have better luck. I installed it in my solar/lithium setup a few weeks ago to increase the power output by 1000 watts. . I also upgraded my inverter battery cables to 3/0 gauge. I'm hooked up to shore power at the moment so haven't been able to test it yet. I tested on the bench with 2 sets of connector cables. It wasn't very good to start the microwave. I put this down to bad contacts and 4 gauge wire. It really worked. I'll admit that the real reason it was so appealing was the remote control. It works well, although I wish it glowed a little longer. I have high hopes for this device and will update this review when I'm back on the road in July 2021.
