Harness the sun’s power today!

If cloud or shade passes, does solar charger automatically recover or does it stop charging?

Yes, this 28w solar panel charger can automatically recover to charge your phone

This solar charger can charge Androids and Apple cellphones and power station?

BigBlue 28w solar panel charger can charge most Androids and Apple cellphones, but our solar phone charger doesn’t include the lightning cable for iPhone or iPad. This product comes with 2 5V USB-A output, so it can’t charge power station.

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/4.0A Max in total, the total theoretical power is 5V*4.A=20W Max. But there are loss in the solar energy conversion process.

High-performance Solar Cell: BigBlue used upgraded solar cells whose conversion efficiency can reach 25.4%. Without metal lines on the front, the solar cells capture more sunlight, increasing electricity generation while providing a sleek design. Fewer front-side components also help these cells stay cooler, enabling solar panels to improve light absorption and extend their lifespan
Built-in Digital Ammeter: BigBlue 28w solar panel charger can measure current real-time value, which is convenient for your use. Note that the value of actual outputs depends on the sunlight intensity, placed angle, temperature, connected devices etc. The foldable design and 4 carabiners are easy to carry for any outdoor activities such as camping trips, climbing, hiking, fishing etc.
Exclusive Smart IC Technology: With the built-in intelligent chip, our solar phone charger detects your device and then delivers its fastest possible charging speed (Single maximum output up to 5V/2.4A, dual maximum outputs up to 5V/4A). If clouds block the sun, this portable solar charger can intelligently detect the sunlight and restart to charge your electronics when there is enough sunlight.
Special PET Polymer Surface: Industrial-strength PET polymer fabric and IPX4 waterproof panels protect your backpacking solar panel from occasional rain or wet fog (USB ports and ammeter are not water-resistant). The zipped pocket keeps your devices safe and clean while camping. Please don’t place your cellphones inside the pocket while charging for fear of overheating
Easy to Use & Friendly Customer Support: Please unfold four portable solar panels in direct sunlight in the open air (No cloud and no shadow), then connect your device to the USB-A port with your certificated cable. This folding solar charger can’t store electricity. You’ll Get: 1x 28W Solar Charger, 1x USB-A to USB-C cable, 4x Carabiners and our friendly customer service
