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.
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
Customers say
Customers find the solar panel well-made and reliable, working effectively even in cloudy conditions and delivering lots of power. They appreciate its portability, noting it folds into a small package for easy transport, and consider it worth the price. The charging speed and sunlight quality receive mixed feedback – while some say it performs well, others report it takes forever to charge and needs optimal sunlight to work properly.
