About this item

  • Solar Chargers for Electronic Devices: Built in USB-A (5v/3a max) Output Port to directly connect in the sunlight and charge Phones (Android and Apple),small power banks(recommend less 10000mA),tablets,usb fans, flashlights, smartwatchs,protable WIFI and other small electronic devices. Note: the solar chargers cann’t store the power and the charging time depends on the capacity of the device.
  • 【SMART IC CHIP TECHNOLOGY & SAFETY FEATURE】Integrated IC automatically detects the connected devices and provides the optimized charging, and an included LED light shows the charging status.FlexSolar ensure 100% safe charging with overcurrent, overheating and short-circuit protection.
  • Rugged Solar Panels Chargers:Utilize ETFE film lamination and encapsulation technologies which provide good light transmittance and weather resistance ability;and made of the monocrystalline A+,make solar panels chargers efficiently convert solar energy into electric energy and conversion rate up to 24% and IP67 protecction class which can work under unexpected weather. Perfect for outdoor power emergency. Note: the junction box isnot waterproof.
  • Portable Solar Chargers:The unfold size is 23.5 x 8.8 x 0.1 inch and 3 fold design with a small size of 7.8 x 8.8 x 0.7 inch (when folded) which is similar size with iPad9 2021 version of 12.9 inches ,only0.99bls (450g) and comes with 2 Carabiners that can be easily squeezed into your backpack, also hung in backpacks and tents. FlexSolar 15W solar charger offers portability and simplicity for your travel,hiking, camping and backpacking.
  • Caution:Do't charge the device with solar panels through the glass. Because The total power is only 15W, The quality of light degrades through the glass and affects the efficiency of the panels' conversion to electricity, which then slows down the charging rate.

Pros & Cons Analysis

Product Pros

  • High-Efficiency Energy Conversion

    Utilizes monocrystalline A+ solar cells combined with ETFE film lamination technology, achieving a high photoelectric conversion rate of up to 24%, which is excellent among similar small portable chargers.

  • Exceptional Outdoor Durability

    The ETFE film provides excellent weather resistance and scratch resistance. The panel achieves an IP67 waterproof rating, making it suitable for harsh outdoor environments.

  • Extremely Lightweight and Portable

    Weighs only 450 grams (0.99 lbs), with a folded size similar to an iPad 9. Equipped with a carabiner for easy carrying or hanging, significantly outperforming traditional bulky charging equipment.

  • Smart and Safe Charging

    Built-in smart IC chip automatically identifies devices and optimizes charging. Provides over-current, over-temperature, and short-circuit protection to ensure charging safety and device compatibility.

  • Multi-Scenario Emergency Power Supply

    Features a direct USB-A output port, capable of providing emergency power for various small electronic devices outdoors, especially suitable for environments without grid power like camping, hiking, and backpacking.

Product Cons

  • Junction Box is Not Waterproof

    Although the panel is IP67 waterproof, the junction box is not, posing a potential risk of damage in humid or rainy conditions, which contradicts its outdoor use positioning.

  • No Built-in Energy Storage Function

    The product itself cannot store electrical energy; it must charge directly when there is sunlight, limiting flexibility for use at night or in low-light conditions. (Inferred based on similar product experiences)

  • Charging Compatibility and Stability Concerns

    User feedback indicates issues with unstable charging rates and poor compatibility with certain devices (e.g., MacBooks), affecting the actual user experience.

  • Relatively Low Power Output

    The maximum output power is only 15W, resulting in slower charging speeds or ineffective charging for some high-power devices (e.g., large tablets, laptops).

  • Lack of Built-in Stand Design

    No built-in stand is included, which hinders optimal panel angle adjustment for sunlight exposure, potentially requiring users to provide their own or manually adjust it, reducing convenience. (Inferred based on similar product experiences)
