FlexSolar 25W Ultra-Portable Solar Panel Charger | USB-A & USB-C

Ultra-Portable Power for the Trail

Meet the FlexSolar 25W, a compact power companion built for outdoor life. When folded, it becomes remarkably slim and light, weighing about 1.2 pounds. An integrated quick-lock carabiner lets you attach it to a backpack or tent, keeping energy within reach as you move between campsites or tackle backcountry trails. The design emphasizes dependable performance in changing light, from bright sun to partial shade, offering a practical energy option for hiking, camping, and emergency prep without overpromising outcomes.

Power and charging on the move

• Dual outputs provide simultaneous USB-A and USB-C charging at up to 5V/3A per port, so two devices can stay powered together.
• Adaptive power distribution and auto-sensing circuitry optimize output for connected devices, helping prevent overcharge and waste.

Efficiency you can rely on

• MPPT Boost technology harvests more energy from sunlight, delivering better performance in partial shade or uneven sun.
• Designed for safe operation across a wide temperature range, with a robust 12-hour continuous-use capability under triple protection (OVP/OCP/OTP).

Built to endure the wild

• Triple-layer construction combines a scratch-resistant surface, UV-stabilized encapsulation, and a shock-absorbing base for rugged use.
• Hidden busbar cells minimize micro-crack risk and have been tested across 2,000+ fold cycles for lasting durability.

Weather-ready by design

• IP67-rated protection guards against dust ingress, water immersion, and heavy rain, with corrosion-resistant hardware for long-lasting performance.
• Includes two carabiners and a fixed strap for fast, secure attachment to packs, tents, or gear on the move.

With an industry-leading 23.2% efficiency in a compact 25W package, FlexSolar aims to maximize energy capture while remaining light enough for everyday carry. Real-world results depend on sunlight quality, shading, and device compatibility, so consider this a strong potential for on-the-go charging rather than a guaranteed outcome. The goal is a versatile, portable energy source that respects your pace and environment.
