BigBlue SolarPowa 28 28W Solar Panel (No Ammeter), 25.4% High Conversion Efficiency, Smart Charging

Ultra-High Conversion Efficiency

Built with advanced back-contact monocrystalline solar cells, it delivers up to 25.4% conversion efficiency for superior energy harvesting. The intelligent auto-restart system maintains consistent charging in low-light or partially shaded conditions, ensuring reliable, hands-free power generation.

Simultaneous Fast Charging for Multiple Devices

It features 1 USB-A and 2 USB-C ports, delivering a combined output of up to 5V/4.8A. It supports simultaneous charging for various devices such as smartphones, cameras, and portable fans, perfect for group use in outdoor adventures.

Ultra-Portable Design

With a four-panel foldable structure, it packs down to a compact 28 × 16 × 3.5 cm and weighs just 0.68 kg for effortless transport. Reinforced metal grommets and included carabiners allow secure attachment to backpacks or easy hanging from branches, delivering a space-saving solution for hiking, camping, cycling, and other scenarios.

Durable and Tough Material

The panel surface is treated with a UV-resistant polymer coating to shield the panel from harmful UV rays, while the rear uses durable 900D polyester Oxford fabric for added strength. This robust construction delivers superior resistance to abrasion, dust, and moisture, capable of withstanding harsh outdoor environments and offering a longer service life.

Safe and Intelligent Protection

An integrated smart IC intelligently recognizes connected devices and matches the optimal charging speed. Comprehensive four-layer protection—covering overcharge, overheating, short circuit, and overvoltage—ensures stable, secure power delivery while safeguarding your devices throughout every charge.
