BigBlue Solar Power Bank 20,000mAh, 20W Fast Charging USB-C External Battery Pack, Portable Charger with 4 Built-in Cables, Solar Phone Charger with Flashlight for Camping Outdoor Trip

This came in a 2 pack deal with the larger panels that I originally wanted. Now I wonder if I didnt need the larger ones. This one seems like it will charge my batteries for extended camping trips just fine. Just keep adjusting it to be perpendicular to the suns rays and it will charge up your stuff. Seems well built

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.

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.

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.

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.

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

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.

Worked fine for about 2 months, now it doesn't produce any power even in full sunlight. I have tried multiple cables/devices, none of them will charge from this solar panel.

Lightweight and decent construction, works well

Excelente produto! Ótima eficiência

We go backcountry camping and this works great for charging our phones and speakers.

Par une belle journée remplie de soleil, j'ai recharger mon Ipad, mon cellulaire et même une batterie externe pour cellulaire. Le lendemain, plus nuageux, seulement une tablette et 50% d'un cellulaire.

Comprei uma para mim e outro para minha mãe. Moro em Porto Alegre e fiquei sem energia este ano por muitos dias, então acho muito importante ter em casa. A placa carregou mais ou menos 25% em 30 minutos.
