It works great, the first one they sent burned out I guess because it would not charge. They sent me another one it is working great ( they sent back to me fast 2 days)

I’ve been using this charger for a bit now, and it's doing exactly what I needed it to. Switching between 6V and 12V is easy, and it works well with both my car battery and an old motorcycle battery I had lying around. I appreciate that it supports multiple battery types, including lithium and AGM, since I’ve got a mix in the garage. The unit feels solid and well-made, and it doesn’t get too hot while running. I also like that it's automatic—it switches to maintenance mode on its own, so I don’t have to worry about overcharging. It’s compact and stores easily when not in use. Overall, it’s been reliable and simple to use. Definitely a good investment if you want to keep your batteries topped off and ready to go.

This worked like a champ. Not only did it charge up my car battery but kept it charged till I needed it. It’s a quality product built well and a great value. A must have for classic car owners who only drive once in a while.

these work great and can be left on for long term use as they stop when the battery is full. i have used the 3 and 4 am models and all are excellent. i do put a connector to each battery so that i don't have to remove any trunk panels to access the battery.
