BigBlue 3 28W Portable Solar Charger, USB Ports, Waterproof, iPhone/iPad/Samsung Compatible

The Full Breakdown

Upgraded Triple USB-A Port

Each maximum output is 5V/2.4A, and the total maximum current is 5V/4.8A. The BigBlue 28W solar charger allows you to charge multiple devices simultaneously (Note: if one device requires a large current, the other two devices may not be charged). The built-in smart charging technology provides optimal, safe charging directly in sunlight.

High-Durability Solar Cells

The solar cells used in BigBlue enhance the charger's durability by reducing heat buildup. These cells are more robust and less prone to damage, extending their lifespan. Without metal lines on the front, they capture more sunlight, increasing electricity generation while maintaining a sleek, modern design. Additionally, our panels protect solar cells from occasional rain or wet fog using a special polymer surface (Note: the junction box is not waterproof).

High Solar Conversion Efficiency

Upgraded solar panels convert up to 25.4% of solar power into free energy in sufficient sunlight, making them some of the most durable panels on the market. They stand up to elements and wear and tear better than conventional panels. Our advanced design incorporates a special polymer surface to protect solar panels from occasional rain or wet fog (Note: the junction box is not waterproof).

Ultimate Portability

With a folded size of 11×6×1.4in and weighing only 1.5 lbs, the BigBlue solar charger is compact and light enough to fit into any camping backpack or hiking daypack. It's also a must-have in an emergency kit. Perfect for extended camping trips or areas with unreliable power grids, this solar charger is a reliable power solution.

Wide Compatibility

The BigBlue USB solar charger generates power for phones (Android and Apple), power banks, speakers, and other small electronics, ensuring you're always charged when the sun is out. Note that we do not provide lightning cables for Apple devices. Our portable solar charger does not store electricity and cannot charge laptops or power stations.

Package & Support

You will receive 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 that any clouds, the angle toward sunlight, operating temperature, and sunlight intensity will affect the real output. We do not recommend using this foldable solar panel inside a window or windshield.
