🔋 Solar Battery Trickle Charger - Sunforce 7W for Enhanced Energy Efficiency Review

This product does exactly what it is supposed to do. The only issue I have is that the cable from the device to the battery is much shorter than any I've ever bought before. I need one long enough to get to the ground and I keep it under the wall of a portable garage. I doubt it says how long his tail was. My problem is not yours. Please if you could make an extension if you need it. Something Sunforce should think about.

Works as described. Connected to my 12 volt battery for my trolling motor. I checked the voltage with a multimeter, it was 12.17, waited about 5 hours in direct sun and checked again. 29.12. waited another day and 12:35 so it's slowly charging the battery which is what I was hoping for. I only use my boat on weekends, so this slow charge during the week suits me. I hate lugging that big ol' battery (class 27) back and forth from the boat to the garage to charge. Hope this saves me a few trips!

This is a preview of what I found out of the box. The panel makes a solid impression. The aluminum frame is good. The supplied cable is short.

It's okay if you know, but it's very important if you don't know. The panel is supplied with plastic mounting clips that snap into the frame. Each clamp has a small set screw that holds the two…

This panel has a simple construction that makes accessing and removing the diode incredibly easy. there is no key) and I had to check if the diode is damaged. As I said, the approach was very easy, which I really appreciate about the electronics. This also makes it easier to change. Although I don't have specs for the diode, the voltage drop was 0.546 in one direction and open in the other, which is in the range a silicon diode should be. Please note that the case and screws are a bit soft and…

Updated Rating (6/22/15): I am updating my rating and adding a 4th star for two reasons. 1) The seller updated the product image which was my main concern and 2) I've been using the product for over a month and it's great. The updated image in the post is a much better representation of what the product actually looks like. This rendering makes it look a bit thinner than it really is. Please see my attached photos to get a better idea of the dimensions. It seems very durable and heavier than I…
