I bought the 1st deal, tried it out for a month, when I was thinking about buying the HF $33 7w model. I believe it's doing a good job as I start the car about every 2 weeks. My battery is in the trunk & I've been leaving it connected, wires going through the backseat & solar panel on top of the rear shelf speakers area. I believe the trickle charge watts are good. I need to hook up a multimeter to see how many watts, but it seems this is a good brand so it should be accurate. I expect more watts than the harbor freight 1.5w. HF 1.5w did let my battery run out of juice a few times, but fun to try out as it was given to me as a gift & I think my battery wants more than 1.5w. so bought a 2nd of these 7w for another car, so that's my review.
