Review on 🔋 WISSBLUE Solar Panel Charger 21W 60W: Fast, Dual USB 2.4A 4.2A Portable Charger for Travel, Camping, Emergency Backup - Compatible with iPhone, iPad, Samsung, Kindle, and More by Glenn Cartwright

On a clear clear day with no clouds managed to charge my Galaxy S9 plus with a 3500mah battery in 3 hours, he has it from about 10:30 to 13:40 charged. In another test, I was able to charge my S9 plus and a 10,000mAh portable battery at the same time (took 4 hours at the time). I placed the solar charger on the grass, I didn't have to point it directly at the sun, I find this solar panel works best when the sun is overhead from 10am to 4pm in the afternoon when the charge works fastest. on phones. Overall this is a great solar charger and I feel safe using it for both camping and emergencies.
