I put it in the sun. Connected to a battery with a 12.2 volt charge. Came back a few hours later and it was much higher. Easy to use.This is what I am going to use to keep my boat batteries charged. No need to keep them plugged into the house. ### ⭐⭐⭐⭐ It appears to do as it claims *by J***H on Reviewed in Australia on 21 August 2024* Installed on vehicle that has a slow draw, after a few hours in a moderate light (winter) location It did increase the voltage and total charge of the battery, please note this battery was not depleted (before and after pics), I am dubious about the claimed 8amp charge rate given the size of the panel, but it does genuinely work. It would likely work much better in summer and given full sunlight location. Unfortunately we found the power draw so havnt had an opportunity/need to leave it on the vehicle since testing. ## Frequently Bought Together - POWOXI-Upgraded-20W-Solar-Battery-Charger-Maintainer, External Smart 3-Stages PWM Charge Controller, 12V Solar Panel Trickle Charging Kit for Car, Marine, Motorcycle, RV, etc - OYMSAE 25Feet SAE to SAE Extension Cable Quick Disconnect Connector 16AWG,for Automotive,Solar Panel Panel SAE Plug(25FT(16AWG)), Charging Adapter - POWOXI Solar Panels Charge Controller, 8A Battery Regulator for 12V Solar Battery Charger, Solar Battery Maintainer and 12 Volt Batteries Power Kit --- ## 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.vu/products/553587639-powoxi-upgraded-20w-solar-battery-charger-maintainer-external-smart-3](https://www.desertcart.vu/products/553587639-powoxi-upgraded-20w-solar-battery-charger-maintainer-external-smart-3) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-10*
