We tested our RV cab battery with a multi-meter before plugging the trickle charger into our cig lighter. It measured 14.89. Two very sunny days went by and the battery measured 13.21. The next day was on and off sun and it registered 12.20. I think the problem lies with the solar panel having lights lit even when it is dark. I contacted the seller with this concern and they said it draws minimum power from the battery when there is no solar. Obviously, it uses power from the battery and here in the midwest we can go weeks without sun this time of year. This trickle charger won't work. Glad the return was easy. ### ⭐⭐⭐⭐⭐ Working well for me. *by T***G on Reviewed in the United States on January 6, 2018* I have been using this product for a number of months now. I have a drain on my car battery that is not cost-effective to repair. This charger has offset that drain, even in single-digit temperatures. ### ⭐⭐ You don't know if it's working or not. *by C***N on Reviewed in the United States on April 24, 2019* The media could not be loaded.  I'll have to return this product. The description says that the red light should blink if it is trickle charging. The alligator clips are connected to the battery and the panel is in the sun, but there is no blinking red light to indicate whether the panel is charging or not. --- ## 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.co.uk/products/51948820-sunway-solar-car-battery-trickle-charger-and-maintainer-multi-function](https://www.desertcart.co.uk/products/51948820-sunway-solar-car-battery-trickle-charger-and-maintainer-multi-function) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-03*
