## Description

desertcart.com : SOLPERK Solar Panel Kit 50W 12V, Solar Battery Trickle Charger Maintainer with Upgrade Waterproof Controller for Boat Car RV Motorcycle Marine Automotive (Without Mounting Bracket) : Patio, Lawn & Garden

Review: Great Quality & Works Exactly as Promised - I bought the SOLPERK 20W Solar Panel Kit to keep the battery on my RV topped off, and it has worked perfectly from day one. The panel feels solid and well-made, and the adjustable mount makes it easy to position for the best sun exposure. The upgraded controller is simple to use and gives you peace of mind that the battery won’t overcharge. Even on cloudy days, it still provides a steady trickle of power. I’ve used it on both my RV and my boat battery, and in both cases it kept everything fully charged and ready to go. Installation was straightforward — the kit comes with all the connectors you need, and the wiring is clearly labeled. Once it’s set up, you basically don’t need to touch it again. This is a great solution if you want a reliable maintainer for a car, boat, motorcycle, or RV battery. It just works. Highly recommended.
Review: I recommend - Good quality solar panel for maintaining battery charge. Easy to set up, solid build, and the controller works reliably. Ideal for vehicles or batteries that sit unused for long periods. Not designed for fast charging, but works well as a maintainer.

This solar charger works exactly as expected and feels well made right out of the box.

Battery life has been more stable since installing it, especially on my car that sits unused for days. Instructions were clear and easy to follow, and the adjustable mount made setup quick. It’s lightweight, portable, and handles outdoor use without issues. Overall, solid performance and good value for a reliable trickle charger.
