How did we get our start?

We discovered that many families still suffer from energy problems. People have to choose the bulky and environmentally unfriendly generator.

What makes our products unique?

In 2020, the first portable LifePO4 power station Cellpowa 500 developed by our company was finally came out. After three years of continuous improvement and repeated testing, Cellpowa 500 is not only able to meet the energy needs of daily life, in addition it has passed the PSE and FCC technical certification and several safety performance tests.

What problem are we solving?

Looking for a way to store enough green and clean energy in a portable generator that customer can take anywhere.

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 High-quality Solar Cell: The solar cells BigBlue adopted 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
