That batteries will slowly leak after being stored for a period of time. And it will consume power for a long time, which will make the battery unchargeable. Therefore, we can use our solar charger to charge and maintain the battery. This product has the following characteristics: : 1. Using high-efficiency monocrystalline solar cells, even if the panel is smaller than the traditional model, it still can achieve higher power efficiency. 2. Equipped with a charging controller, it has various protection functions that never cause any damage to the battery. 3. It is convenient to charge as long as there is sunlight to charge the battery. 4. Easy to connect. No need to pull long and complicated extension cords. At the same time it works under human body safety voltage and is very safe. 5. The surface is made of glass and easy to clean. Reminder: 1. Before connecting the wires, separate the red and black clips to avoid collision and short circuit. 2. This product is a solar charging board which should be installed in a place where the sun is shining directly. The more sunlight, the better the charging effect.

Will buy again. Highly recommended seller. Review: Great solar trickle feeder for use when storing RV's, boats, cars or motorcycles. - Works as stated. Good value. I use it to trickle feed my motorhome starter battery while it is stored. The cables are a fair length for most; however, I did need to extend mine because I wanted it on the roof of the motorhome where it was in the sun all day and not sitting on the ground. It does come with a handy bracket that can be used as a stable stand, or for mounting somewhere. It also has a controller to make sure it doesn't over-charge. I'll see how it goes for a few months and update the review if need be. ## Features - ☞【Excellent Quality】The 20W solar panel adopts well-constructed monocrystalline cells with high conversion efficiency up to 24%.

Will buy again. Highly recommended seller. ### ⭐⭐⭐⭐⭐ Great solar trickle feeder for use when storing RV's, boats, cars or motorcycles. *by G***A on 12 January 2026* Works as stated. Good value. I use it to trickle feed my motorhome starter battery while it is stored. The cables are a fair length for most; however, I did need to extend mine because I wanted it on the roof of the motorhome where it was in the sun all day and not sitting on the ground. It does come with a handy bracket that can be used as a stable stand, or for mounting somewhere. It also has a controller to make sure it doesn't over-charge. I'll see how it goes for a few months and update the review if need be. ### ⭐⭐⭐⭐⭐ Works Perfect *by L***. on 6 September 2026* I bought a new Hydraulic Dump Trailer and needed a way to keep the battery on the Hydraulic Unit charged, since I park it away from all the plugs I have. Every time I have checked the battery, it has had a full charge, even in the cloudy days. It doesn't take much sunlight to keep it charged. The wiring is simple and the installation is super easy, especially with the instructions included. The length of the charging cable that came with it is very long. I am thinking of ordering one for my lawn mower and my motorcycle. The charging panel that tells the charge on the battery is really easy to understand also. I will give it the 5 star recommendation. ## Frequently Bought Together - SOLPERK Solar Panel Kit 20W 12V, Solar Battery Trickle Charger Maintainer + Upgrade Controller + Adjustable Mount Bracket for Boat Car RV Motorcycle Marine Automotive - SEAFLO Water Diaphragm Self Priming Pump 3.0 Gallons/min (11.3 Lpm) 45 PSI New Rv/Marine 12 Volt Dc / 12 V Demand Fresh - ML7-12 - 12 VOLT 7.2 AH SLA BATTERY - Mighty Max Battery brand product, black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/282045577-solperk-solar-panel-kit-20w-12v-solar-battery-trickle-charger](https://www.desertcart.be/products/282045577-solperk-solar-panel-kit-20w-12v-solar-battery-trickle-charger) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-11-14*
