⚡ At a Glance
- • Power Output: Built-in USB-A output, 5V/2A max, 10W total power, monocrystalline panel with up to 24% conversion
- • Best for: Day hikers, campers and travellers who need direct sunlight charging for small electronics
- • Not ideal for: People who need onboard battery storage or to charge large devices directly
Compact foldable solar panel with a single USB-A 5V/2A output for direct charging. Panel uses monocrystalline cells and ETFE lamination for efficient light transmittance and weather resistance.
Reliable On-the-go Charging – Thanks to the 5V/2A USB-A output
A single USB-A output supplies up to 5 volts at 2 amps directly from the panel, with a 10W peak output when sunlight is strong. Monocrystalline A+ cells and ETFE lamination improve light transmittance, helping the panel reach a conversion rate quoted at up to 24%.
Directly plug phones, USB headlamps and small powerbanks into the USB-A port for daytime charging. Charging speed depends on sunlight and the device's battery capacity, making daytime top-ups practical on long outings.
Weather-resistant Build – With IP67 rating and rugged lamination
ETFE film lamination and encapsulation protect the panel surface from abrasion and moisture, while the overall unit carries an IP67 rating for water and dust resistance. A junction box is present but is explicitly not fully waterproof and should be shielded from direct water exposure.
Panel can handle splashes, spills and light rain, so outdoor use is less stressful during unpredictable weather. Keep the junction box dry to avoid compromising the electrical connections.
Truly Portable Design – With foldable format and included carabiners
Folds down to roughly the size of a small tablet (listed as 6.3 x 4.8 x 1 inches) and weighs around 0.44 lbs, with two carabiners supplied for easy hanging. A USB-to-USB-C adapter is included for wider compatibility with modern cables.
Folds small enough to slip into a daypack pocket and can be clipped to a rucksack or tent for hands-free charging. Lightweight construction reduces pack weight for long hikes and multi-day trips.

❓ Frequently Asked Questions
Q: Can the charger store power for use later?
A: No, the panel cannot store energy; it supplies power only while exposed to sunlight, so a powerbank is needed for charging after sunset.
Q: Is the solar panel fully waterproof?
A: The panel carries an IP67 rating for water and dust resistance, but the junction box is not waterproof and should be kept dry.
Q: What devices can be charged directly?
A: Any small electronic that accepts USB-A charging at 5V, such as phones, USB fans, flashlights, headlamps, smartwatches and Bluetooth headphones; charging speed depends on sunlight and device battery capacity.
