### ⭐⭐⭐⭐⭐ Review
*by M***E on 19 June 2025*

Installed in my van to charge my Temgot 460ah battery off the alternator/battery. Easy to install, easy to set for your battery type. Lights stay on so a small draw but not significant. I got the 40amp version and it's great for my use. Went on an advanture with it on washboard roads for 3 hours- still performs like a champ.
