Review on 🌞 BigBlue 15W Portable Solar Charger with Dual 5V/2.1A USB, Folding Camping Solar Panels and Type-C Cable, Compatible with iPhone 11, Xs, XS Max, XR, X, 8, iPad, Samsung Galaxy, LG, and More by Aaron Barker

Great charger but the packaging is regular color and not a regular Revain box. In fact, the box was damaged. This item was sold by Big Blue but shipped to Revain so this is a rare miss for Revain. The charger is well made, made of high quality materials, light weight and easy to carry. I particularly like the slim profile and magnetic closure. The charger also has a pocket for cables and other small accessories, which is nice. However, I think it's best paired with a portable battery so you can charge it with a solar charger. A side note: 21% is pretty standard efficiency for solar panels, so I don't know how they claim other brands only offer 11-14%, and I don't expect any other significant performance losses. I look forward to using it on my next hike.
