I wouldn’t use it as a parachute either. **Q: The Solar charge control keeps fading out, I am just trying to use the solar panel to charge usb devices. So far no luck, is mine broken?** A: Do you have a 12v battery attached? You need a battery attached, the panel is not designed to run anything directly, it is designed to trickle charge a car battery. The power from the car battery is what will charge your USB devices. **Q: can i leave this system connected to the car permanently ie even whilst driving ? TIA Pam** A: I wouldn't have thought so, you would need to isolate the controller, as your car alternator will be charging your battery as you are driving. there are controllers on the market that are able to be connected to a running charging system, they are a lot more expensive than this system. **Q: Is the solar panel waterproof, can i mount it outside?** A: The solar panel is fine, but I do get issues occasionally with the controller when wet. ## Frequently Bought Together - Topsolar Solar Panel Kit 20W 12V Monocrystalline with 10A Solar Charge Controller + Extension Cable with Battery Clips O-Ring Terminal for RV Marine Boat Off Grid System - ExpertPower 12v 7ah Rechargeable Sealed Lead Acid Battery - JVR Automatic Chicken Coop Door Opener with Timer, Programmable, Aluminum Coops Doors, Electric Run Automatic Chicken Door Auto Opener, Actuator Motor, Safety Feature --- ## 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.com.eg/products/160054133-topsolar-20w-12v-solar-panel-kit-battery-charger-maintainer-10a](https://www.desertcart.com.eg/products/160054133-topsolar-20w-12v-solar-panel-kit-battery-charger-maintainer-10a) --- *Product available on Desertcart Egypt* *Store origin: EG* *Last updated: 2026-05-19*
