Review on 🌞 Foxelli Triple USB Solar Charger 21W - Portable: Versatile and Efficient Charging Solution for Your Devices by Joseph Marquez

For starters I have the 21W option. I can't comment on the strength or durability as I haven't owned this product for a long time. That being said I used it once, I put it on my car dashboard on a VERY cloudy day and plugged my Galaxy S8, which was 80% charged, into all 3 USB ports to charge. In order from left to right they read IOS/ANDROID/ANDROID. IOS and average Android showed the same time to fully charge my phone which is 3 hours. However, Android on the far right showed the best time at just over 2 hours for a full charge. So I don't know what the difference in output is, but the fastest by far is the rightmost USB. Haven't had a very sunny day to test this out but for the purposes I bought this solar charger for I couldn't be happier and glad I bought it. If you can still get it, buy it for same-day shipping. It's worth it. (Everything is shutting down because of the coronavirus, so I'm emphasizing the "do it fast" part)
