Good For Harbor Freight Solar Panels

Works well. The connectors require a little bit of muscle when connecting to my Harbor Freight solar panel and camper battery, but a tight fit is good. I use it with my 1.5 Amp Harbor Freight solar panel. The small panel has never fully charged the battery on a camping trip. It has a yellow light indicating charging and a green one that indicates full battery. You can’t beat it for the price and ease of installation. Ready to go out of the box.
