I was running a fan all night and my battery was at 95%. I placed this on my dashboard and over the steering wheel as I needed to leave the van for the day. It was a cloudy/sunny day. So no bright sunshine hit this panel for 12 hours. It went to 100% at the end off the day. Happy with it. Only thing is the clamps, flimsy and at one point I know they will have to be replaced. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars this thing is great *by A***R on Reviewed in the United States on September 12, 2013* use it to charge my deep cycle fishing battery - fully charges in about 1 day - with good sun --- ## 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.id/products/10376362-40w-40-watt-high-efficiency-mono-crystalline-solar-panel-battery](https://www.desertcart.id/products/10376362-40w-40-watt-high-efficiency-mono-crystalline-solar-panel-battery) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-13*
