desertcart.com : Voltset 12V Solar Battery Charger - 20W Waterproof Solar Panel Kit with Smart MPPT Controller - Trickle Charger Maintainer for Car RV Boat Marine Trailer Automotive Trailer Truck Motorcycle : Patio, Lawn & Garden

Review: Excellent product investment - This solar charger is amazing! It really works on my generator battery which was so low I couldn’t start my generator by pushing the button. And there’s no way I can start it by pulling on the cord. After a good day of sun (6-7 hrs) on the panel my generator started up beautifully! I love how the unit shows battery charge level. Pictures show my temporary set up to see if it would work. Now I’ll get it mounted in its permanent location. And since I have 2 generators I’ll be buying a second charging system!
Review: Easy install and includes all mounting hardware. - This panel installation was incredibly straightforward. It comes with all the necessary mounting hardware and even includes inserts if needed for your specific setup. The bolts that secure the panel to the bracket feature wing nuts, making it effortless to attach to the bracket. However, since I had to install the panel approximately 25 feet away from my generator, I had to use an extension cord for the connection. This added a bit of complexity to the process. To make matters worse, the extension cable had the positive and negative reversed, so I had to create a small conversion cable to correct the polarity. After installing the panel and charge controller, I confirmed that it was indeed generating power. Considering the current winter season and the low angle of the sun, I’m getting 18 watts from the panel. Will have to wait and see what the summer season brings. It is keeping my generator battery charged and I have seen that it does automatically stop charging when the battery is fully charged. I’ve been using this system for two weeks now, and it has been functioning flawlessly without any issues.

### ⭐⭐⭐⭐⭐ Better than expected.
*by B***Y on January 20, 2026*

Very pleasantly surprised with this charger. Bought it to keep my boat batteries charged up and it is doing a great job. So much easier that using the extension cord and battery charger. Just hardwired the end of wires with the rings to the battery and did get a cord extension so the wires would hang outside of the cover so I can easily see the status of the charge module. Very happy with this buy. Fingers crossed it lasts!!! This is the ext. cable I got......... SAE Extension Cable 12AWG, SNLLMZI SAE to SAE Extension Cord DC Power Automotive Extension Cable for Solar Panels,Cars, RVs,Trucks,Boats, etc (3.3FT)
