About this item

  • Solar Chargers for Electronic Devices: Built in USB-A (5v/2a 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 19.4 x 6.3 x 0.5 inch and 3 fold design with a small size of 6.3 x 4.8 x 1 inch (when folded) which is similar size with iPad9 2021 version of 12.9 inches ,only0.44bls (200g) 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 10W, 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 Conversion Efficiency

    Utilizes monocrystalline A+ grade solar cells with a photoelectric conversion rate of up to 24%, performing excellently among similar portable solar chargers and enabling more efficient use of sunlight. (Inferred based on experience with similar products)

  • Extremely Portable and Lightweight

    Weighing only 200 grams with a folded size similar to an iPad 9, and equipped with a carabiner, it significantly outperforms many competitors of the same power rating, greatly facilitating outdoor carrying and mounting.

  • Strong Outdoor Weather Resistance

    The panel uses ETFE film lamination technology and achieves an IP67 waterproof rating, allowing it to maintain good performance and durability even in harsh weather conditions such as rain and dust.

  • Smart and Safe Charging

    Built-in smart IC chip automatically recognizes devices and optimizes charging, providing triple protection against overcurrent, overheating, and short circuits, ensuring a safe and reliable charging process.

Product Cons

  • Low Charging Power

    With a maximum output power of only 10W, the charging speed is relatively slow for modern smartphones or power banks with slightly larger capacities, failing to meet fast-charging demands.

  • Waterproof Design Flaw

    Although the panel claims an IP67 waterproof rating, the junction box is explicitly marked as not waterproof, creating a significant vulnerability in humid outdoor environments and limiting its all-weather usage scenarios.

  • No Built-in Energy Storage

    The product lacks energy storage capability; it must be directly connected to a device for charging only when there is sunlight, preventing its use as a standalone power bank and limiting flexibility.

  • Folding Mechanism Durability Risk

    Some user feedback indicates potential internal cable short circuits or damage at the folding points, suggesting possible durability concerns with the folding design under long-term use.
