40W Dual Fast Charging Solar Charger
This charger is equipped with a QC3.0 USB-A and PD2.0 USB-C interface, each with a maximum output of 18W, enabling fast charging for multiple devices such as smartphones (Android/iOS), tablets, and power banks simultaneously. Additionally, the 19V DC interface can provide a maximum output of 40W, suitable for charging small devices. The built-in smart IC chip technology automatically identifies connected devices and provides an optimized charging solution. To ensure maximum efficiency, it is recommended to use a single port for charging. (Note: This device is an instant energy conversion device and does not have energy storage functionality.)

Efficient and Reliable
Utilizing advanced monocrystalline silicon cells, it achieves a high energy conversion efficiency of 24%, ensuring maximum energy output even in low-light conditions. The panel features IP67-rated dust and water resistance and is coated with an ETFE laminate, offering superior resistance to rain, dust, and wear compared to standard PET panels. While the junction box is not fully waterproof (it is recommended to store it indoors during heavy rain), its robust design ensures reliable long-term operation in harsh environments.

Portable Design
This 40W solar charging panel features an ultra-lightweight foldable design, measuring just 8.0 x 11.1 x 1.8 inches when folded and weighing only 1.76 pounds, making it ideal for mobile camping and off-grid adventures. It can be easily packed into a backpack or emergency kit, ensuring reliable power supply anytime, anywhere.

Packaging and Support
The purchase includes 1 x 40W solar panel, 2 x clips, and 1 x user manual. For optimal charging efficiency, it is recommended to position the solar panel at a 45° angle toward direct sunlight. Please note that shadows or partial obstruction may reduce performance by up to 70%. Although the solar panel has an IP67 waterproof rating, please avoid submerging it in water for more than 30 minutes.
