We discovered that many families still suffer from energy problems. People have to choose the bulky and environmentally unfriendly generator.

The Best Portable Solar Charger Reviewed by Wirecutter
" The BigBlue 28W USB Solar Charger produces the most power of any portable solar charger we’ve tested, and it has unique features that make it more versatile and durable, including three output ports (versus two on most other chargers), and an expansive but lightweight array of panels to catch every last ray of sunlight. Smaller and lighter than other options with similar output, so it can more easily fit into a camping backpack, hiking daypack, or emergency kit." -- By Wirecutter Editor

This solar charger can charge my cellphones at night?
No, this portable solar charger can't store the electricity, you need to connect your device to the solar panel in direct sunlight outdoors.
Why the real output is different from the power claimed?
This product has 4 piece panel, each is 7w, so the power is 4*7w=28W; Theoretical output is 5V/2.4A Max for each port, 5V/4.8A Max in total, the total theoretical power is 5V*4.8A=24W Max. But there are loss in the solar energy conversion process.
What's the auto-restart function?
Any cloud or covering arrives may knock the value of output down, but this folding solar panel charger can automatically recover to normal charging speed when there are enough sunlight.
This solar charger can charge Androids and Apple cellphones?
Yes, but our solar phone charger doesn't include the lightning cable for iPhone or iPad.
What does the red indicator mean?
The red LED light will go on when the solar panels works normally; It will flicker when there are overcurrent or short circuit.

There was a problem filtering reviews right now. Please try again later.
Took one to NZ for a month of camping, the Gopro and phones and speakers needed charged often, so beautiful there, many photos. Charged all my devices and my friends too, no worries. These things are even sand fly resistant, unlike my friend and I. I even used it to charge my small usb bug zapper, super handy
Seriously, these really are legit, the ratings are high for a good reason. I suggest you buy two, one for your awesome self(your deserve it). Gift one to a deserving dear friend, random hitchhiker, backpacker or camper in need ..and the universe will smile upon you... which I have done twice now, so trust me on this. Its why im here writing this review because i need to order one and i wanted everyone to know how solid, dependable, strong and what a good value they are.
*not sponsored by this company , its representatives or anything like that
** but if you guys want to send me a free one for this review, i can wait a day or two, but not too long, i have rafting season coming up soon..
In practical use, the panels may not always be facing the sun directly. On a sunny day, when the panels are in a stationary position, I typically receive an output of 3-7 watts, depend on where the sun is and how intense it is. Such output is sufficient to charge my phone and power bank. Although it may not be as fast as charging from a wall outlet with fast charging capabilities, it is still a great source of free energy.
I was pleasantly surprised by the performance of this small and lightweight panel. However, it is important to note that when the angle is low, such as 20 degrees, the output drops significantly to around 1 to 2 watts. This also applies when the panel is placed behind a glass window. Some of my power banks do not charge at this low wattage. The panel works best when there is only air between it and the sun.
Overall, I am satisfied with this product.
