Review on 🌞 Portable Foldable Solar Panel Charger - 100W | Compatible with Solar Power Stations, Phones, Laptops | Ideal for Family Camping, RV, Travel, Hiking, and Outdoor Activities by Tai Waldbillig

I haven't used it much yet. I've tried a cell phone and also a large lead acid van battery. Likes: Well made, wide range of cables and adapters, folds compactly, built in mounts, no problem charging your phone with just sunlight through a large skylight, and even better outdoors. Issues (minor): The posts only offer one angle (not adjustable). I'm also not sure if it puts out 100W of power - I measured the current and voltage while charging a large RV battery and got 3.5 amps and 13.5 volts (measured with an accurate multimeter ) or get about 50 watts. It was a clear day at 4:00 p.m. and the latitude is north (Portland, Oregon), so maybe 100 watts is ideal conditions (noon and closer to the equator). Still enough to charge multiple phones or tablets, but not as reliable as I expected. The specifications do not specify the conditions necessary to obtain 100 watts of power.
