1. Portable Solar Charging
This 15W foldable solar panel charger provides a practical source of USB power for outdoor and mobile applications. It uses monocrystalline solar cells with a stated conversion efficiency of 22.5% and is designed to charge compatible 5V USB devices directly under suitable sunlight.
2. USB-C and USB-A Outputs
• USB-A Output: Provides 5V/2A output for compatible phones, MP3 players and other USB-powered devices.
• USB-C Output: Provides 5V/3A output for compatible mobile devices and tablets.
• Direct Solar Charging: Connected devices can be charged from the panel without a separate AC power source.
• Charging Performance: Actual output and charging time depend on sunlight intensity, panel orientation, weather conditions and the connected device.
3. Three-Fold Portable Design
• Compact Folded Size: Folds to 190 × 182 × 30 mm for storage in a backpack or vehicle.
• Expanded Charging Area: Measures 675 × 182 × 20 mm when unfolded.
• Lightweight Construction: The solar charger weighs 0.44 kg for convenient transport.
• Four Carabiners: Allow the panel to be attached to compatible backpacks, tents or other suitable mounting points.
4. Outdoor-Oriented Construction
• Monocrystalline Solar Cells: Provide a stated conversion efficiency of 22.5%.
• Layered Encapsulation: Uses a TPF, EVA, monocrystalline-cell, EVA and black TPT construction.
• 600D Oxford Fabric: The folding body is made with black water-resistant Oxford fabric.
• Declared IP65 Rating: Designed to resist dust and water exposure under the supplier’s stated rating. The unit should not be immersed, and charging ports should be protected from water during use.
5. Outdoor and Emergency Applications
The foldable solar charger is intended for outdoor and temporary charging situations where mains electricity may not be available. Suitable applications include camping, hiking, cycling, climbing, travel and emergency preparedness.
Because the product relies on available sunlight, its charging speed cannot be compared directly with a household wall charger. For best performance, unfold the panel completely, position it toward direct sunlight and keep it free from shade.
