BigBlue 20W Portable Solar Panel with Kickstands, USB-A and USB-C(5V/2.4A per Output), Solar Panel Charger for Camping, Higher Efficiency, IP65 Waterproof, Compatible with Phones, Tablets, Power Bank

It was a sunny afternoon so I decided to try this out. I put it out in my backyard at the 90 degree angel facing the sun. My Samsung phone was at 70 percent but when I finished setting this up it showed 69 percent. I plugged it in for 15 minutes and when I returned my phone was showing 81 percent.I did not think it would do that but it did work as intended. Note I did use my own phone cable to attach from the usb a port to my phone plug.

Just received this product, so have not had much time to use it, but out in the July sun today it charged my iPhone 10% in less than half an hour, so it does what I needed done.

Out of all the power panels, this one charges well and quickly. Charged up the phone and then the power bank.

I took this on a 10 day backcountry trip intending to recharge various electronics for navigation and communication. Unfortunately it would not charge them. It would however charge a battery pack which I then used to charge the devices. UPDATE - The seller has been working diligently to identify the problem. We’re still not sure why the device wouldn’t charge, but to ensure it wasn’t the panel they graciously offered to send a replacement. Kudos on the customer service! Once the new panel arrives I’ll update the post again.

Each panel Is about he size of an open hand. only tested it so far. it charged my cellphone 4% in a few min!! very happy

Bigger than advertised and not easy to use when backpacking.

I opened the box, attached it to my iPad mini, placed the panel in sun , laid back in my hammock…… about 15 minutes charged from 30%- 75%…. Pretty amazing. Always remember to not try to charge to 100%…. Just like an ev, batteries happily charge to about 80% and then slow quite a bit. Best to charge more often for less time.

Sturdy compact panel. Used on the beach to keep things like portable radio and phone charged. I like the built in stand and rigid structure. Easy to fold up and carry.For hiking would go with a smaller 10w panel unless lower light.
