Solar Panels Charger with Digital Ammeter - BigBlue 28W SunPower Camping Solar Panel
The BigBlue 28W solar panel charger is equipped with a built-in digital ammeter, allowing you to measure the real-time current value for convenient usage. It's essential to note that the actual output values depend on your connected devices, sunlight intensity, and the cable used. For instance, if your device has a limited input current of 1A, such as the iPhone, the ammeter's value will typically show between 0.8A and 1A theoretically.
Higher Solar Conversion Efficiency
Featuring SunPower Solar Panels, known for their durability, this charger boasts a conversion efficiency of up to 24%. Even if clouds occasionally block the sun, the charger intelligently detects sunlight and resumes charging your devices within 30 seconds once sufficient sunlight is available. Its foldable design and four carabiners make it highly portable, perfect for outdoor activities such as camping, climbing, and fishing.
Exclusive Smart IC Technology
The BigBlue 28W solar charger comes with a built-in intelligent chip that detects your device and delivers the fastest possible charging speed. It provides a single maximum output of up to 5V/2.4A and dual maximum outputs of up to 5V/4A, compatible with all 5V Android and Apple devices. However, it does not include a lightning cable for Apple devices.
Special PET Polymer Surface
Constructed with industrial-strength PET polymer fabric, the charger features IPX4 waterproof panels that protect it from occasional rain or wet fog. However, the USB ports and ammeter are not water-resistant. The zipped pocket helps keep your devices safe and clean during camping, but it's advised not to place cellphones inside while charging to prevent overheating and damage.
Easy to Use & Friendly Customer Support
To use, simply unfold the four solar panels in direct sunlight without any cloud or shadow, then connect your device to the USB-A port using a certified cable. The package includes a 28W Solar Charger, a USB-A to USB-C cable, four carabiners, and offers friendly customer service.
