BigBlue 28W Portable Solar Panel Charger, USB Solar Phone Charger with SunPower Solar Panel for Hiking Camping Emergency Outdoors

The solar panels fit nicely in my backpack, and it's easy to unfold, attach to a portable battery, and get charging. I haven't been able to test it long-term yet, but everything seems to work great and I'm hoping to bring it along many trips in the future!

I love it charges by sun and not plugged in the home save money and not hock up to electricity

I used this solar charger on a 10 day Scout campout. I was able to keep my batteries and phone charged the entire time. I started with a fully charged 40k mAh battery for charging my phone at night and a fully charged 5 mAh battery for charging during the day while hiking. Network service was extremely poor so my phone was constantly running down. I was able to completely recharge the smaller battery daily and the top off the larger battery in a day halfway through the campout. I got about 20k mAh in just a few hours. Additionally, because it has three USB outlets I was able to charge multiple other devices belonging to others at the same time. It's durable (no damage) and tolerant of moisture - it got condensation on it with no problems. I like the four rings for attachment and the included carabiners. They were useful for stringing it up for optimal sun. The Velcro pouch was useful for storing cords and carabiners. I didn't put the batteries or phone ion it for fear of overheating. Not sure if that would have happened but I didn't want to take a chance. The only downside is there is another model with a built-in amp meter. Some other folks on the campout had that model. However, it only has two outlets. It would have been nice to have the meter, but I'm not sure it's worth the trade for one fewer outlet and the higher cost. Overall highly recommend this charger.

works great

performs as advertised, which is all I ask when purchasing any product. very easy to use. built well. charges my phone quickly. 5 stars

Works! Compact. Arrived very quicky. Great price.

Delivered the charge needed! Well made and will see how it holds up!

The first solar charger I've used that is functional. I have another brand with a 7 W panel and small battery pack, it almost functions. I hooked this panel up to my 20k mAh battery bank, and in 3 hours I gained about 25% charge, and the panel can put out twice that amount of power. I wish the pocket was large enough to hold more, but without stretchy material, it is pretty limited in volume.

i never received the product but i paid for it

laying on the lawn under direct sun light barely charges a cigarette vuse. i wouldn't recommend this item to anyone it is JUNK.
