Compact Solar Panel Charger for Outdoor Adventures

High-performance Solar Cell: BigBlue used upgraded solar cells with a conversion efficiency of 25.4%, maximizing energy capture and minimizing waste. Front-side metal lines are eliminated, allowing these cells to absorb more sunlight and enhance electricity generation, while maintaining a sleek design.

Built-in Digital Ammeter: The BigBlue 28W solar panel charger features a built-in digital ammeter that measures the real-time current value, providing convenience for users. Note that the actual output depends on sunlight intensity, angle, temperature, and connected devices. The foldable design and 4 carabiners make it easy to carry for outdoor activities such as camping, climbing, hiking, and fishing.

Exclusive Smart IC Technology: Our solar phone charger includes a built-in intelligent chip that detects your device and delivers its fastest possible charging speed. The single maximum output is up to 5V/2.4A, while the dual maximum output is up to 5V/4A. This portable charger intelligently restarts charging when sufficient sunlight is detected, even if clouds temporarily block the sun.

Special PET Polymer Surface: The industrial-strength PET polymer fabric and IPX4 waterproof panels protect your solar panel from occasional rain or wet fog. The USB ports and ammeter are not water-resistant. A zipped pocket keeps your devices safe and clean while camping. Avoid placing your cellphones inside the pocket while charging to prevent overheating.

Easy to Use & Friendly Customer Support: To use this folding solar charger, unfold four portable solar panels in direct sunlight and connect your device to the USB-A port with a certified cable. This folding solar charger does not store electricity. What you get includes 1x 28W Solar Charger, 1x USB-A to USB-C cable, 4x Carabiners, and our friendly customer service.
