This solar panel charger can’t store electricity, it must be placed in full sun outside, and then connected to your electronics simultaneously to start charging.
The maximum output of each port is 5V/2.4A, the product output power will decrease when the solar radiation intensity becomes low.
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 enough 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.
Upgraded Triple USB-A Port: Each maximum output is 5V/2.4A and the total maximum current is at 5V/4.8A. BigBlue 28w solar charger allows you to charge multiple devices at once (Note: if one device requires a large current, the other two devices may not be charged). The built-in smart charging technology can provide optimal and 100% safe charging in direct sunlight
Used Back Contact (BC) Solar Cell: High-quality BC cells improve the solar charger’s durability by reducing heat buildup, making them more robust and less prone to damage, which extends their lifespan. Without metal lines on the front, these cells capture more sunlight, enhancing electricity generation and providing a sleek, modern design.
Higher Solar Conversion: Upgraded solar panels convert up to 25.4% of solar power into free energy in enough sunlight, which is the most durable panels at present, standing up to elements and wear and tear better than conventional panels. BigBlue uses a special polymer surface to protect solar panels from occasional rain or wet fog ( The junction box is not waterproof)
Portable Camping Solar Charger: With a folded size of 11× 6×1.4in and a lightweight (1.5 lbs) design, it is compact and light enough to fit into any camping backpack or hiking daypack. It is also a must-have for stashing in an emergency kit. BigBlue solar phone charger is a great option if you’re taking an extended camping trip or traveling somewhere with an unreliable power grid
Wide Compatibility: BigBlue USB solar charger offers a tiny power plant that can generate power for your phone (Android and Apple), power bank, speakers, and other small electronics to keep them charged when the sun is out (Note: we don’t provide the lightning cable for Apple devices). Our portable solar charger can’t store electricity and can’t charge laptops and power station
Package & Support: You will get a BigBlue 28W Solar Panel Charger, a 50cm USB-A to USB-C Cable, four Carabiners, a User Manual and our friendly customer service. Note: Any clouds, the angle toward sunlight, operating temperature and sunlight intensity will affect the real output, we don’t suggest you use this foldable solar panel inside of a window or windscreen
