Review on 🌞 ALLPOWERS Foldable Solar Panel Charger 100W - Dual 5v USB & 18v DC Output for Laptops, Portable Generators, 12v Cars, Boats, RV Batteries by Quinton Dawon

Panel 18V/100W arrived quickly, no instructions, contacted seller to email instructions. So far had the opportunity to use the panel twice. charged a cell phone from a 5V USB socket and charged a car battery with charging clips. Put a voltmeter on the solar panel before connecting to the battery, the output was 22V, after connecting the voltage dropped to 13.3 as it should, it looks like the reducer is working properly. So far I'm happy with the compactness and ease of use.
