It helps keep my trucks battery topped off. Review: Pretty Nice - This wasn't seamless or simple for me to install in my Mother-In-Law's Nissan Juke. The cable wasn't quite long enough and it turn out the rear window is tinted so it seems the performance is reduced. These are not issues with the unit. I thought the packaging was excellent and the kit had everything you should need for installation. I found that the cabling is a little short for how I had routed the cable, and splicing the 16 ga wire with crimp connectors was...nightmarish for my fat fingers. Buy yourself and extension and save yourself some grief. The MPPT controller makes it easy to operate, no over charging and no back feed from the battery to the solar cell at night. I also purchased a battery connector kit that came with an inline blade fuse to protect the whole system from the unexpected. I wish there was an easier way to mount the solar panel inside the car. Hoping a valid solution will come to me soon. At the moment it is using up a fair about of cargo space in the hatch area. ## Features - Battery Savior: This is designed to charge and maintain 12V rechargeable batteries.

It failed. The solar panel is probably fine, but the charger was very erratic. If there is nothing but sunny weather it seems to do ok, but if you get a few cloudy days it seems to drain the battery quickly, even though the only thing attached to the battery was this charger, there were no loads using battery power. After a couple days (with no load), the battery would read 12.2 volts. I hardly ever saw over 13 volts which is what it should have been if this charger was working correctly. ## Frequently Bought Together - SUNAPEX 20W Flexible Solar Panel with MPPT Charge Controller, Solar Battery Charger Maintainer, 12V Waterproof Solar Trickle Charger for Car, Motorcycle, Boat, Marine, RV, Trailer, Tractor,Truck, etc - OYMSAE 25Feet SAE to SAE Extension Cable Quick Disconnect Connector 16AWG,for Automotive,Solar Panel Panel SAE Plug(25FT(16AWG)), Charging Adapter --- ## 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.tn/products/691771937-sunapex-mppt-20watt-12v-solar-car-battery-trickle-charger-maintainer](https://www.desertcart.tn/products/691771937-sunapex-mppt-20watt-12v-solar-car-battery-trickle-charger-maintainer) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-06*
