Product overview A portable solar charging system that combines a foldable solar panel, an integrated charge controller with MPPT tracking, and multiple device protections. Designed for charging phones, power banks, and charging leadacid batteries with improved conversion efficiency and continuous monitoring during charging. Key benefits Reliable protection for devices: Builtin multiple protection features reduce the risk of damage from overcharge, overdischarge, short circuit, reverse polarity, overcurrent, and overvoltage. Higher charging efficiency: Autofocus MPPT tracking maximizes solar energy harvest and adjusts dynamically for better conversion rates compared to fixed controllers. Durable and portable: Foldable panel construction and longlasting materials make the unit easy to carry and suited for repeated outdoor use. Simple battery support: The solar regulator and controller can be used to charge leadacid batteries, enabling small offgrid power setups and battery maintenance. Features and specifications Foldable solar panel: Compact when folded for transport, expands to a larger surface area for generating power. Constructed from durable materials for lasting use. Solar charge controller with MPPT: Autofocus MPPT tracking provides twoway focus tracking and continuous detection during charging to maintain power transfer. Multiple protections: Integrated safeguards for device and battery protection during charging cycles. Compatibility: Suitable for charging mobile phones, power banks, small electronics, and charging leadacid batteries where appropriate connectors and battery settings are used. Performance focus: Designed for steady, efficient charging and ongoing monitoring of charging status to maintain stable operation. Practical uses Camping and outdoor trips: Keep phones, power banks, and small USB devices powered while off grid. The foldable panel fits into a backpack and unfolds to capture sunlight. Remote battery charging and maintenance: Use the solar regulator and controller to charge leadacid batteries for lighting, radios, or small DC loads at cabins, workshops, or field sites. Emergency backup power: Run the panel during power outages to maintain phone connectivity and charge essential devices without relying on grid power. What makes this product stand out Integrated MPPT controller with continuous detection and twoway tracking improves energy conversion and adapts to changing sunlight conditions. Multiple protection features protect both devices and batteries during charging. Foldable and durable design balances portability with practical power output for a range of outdoor and emergency applications. Usage tips Position the panel toward direct sunlight for performance and avoid shading on any portion of the panel. Follow battery manufacturer recommendations when charging leadacid batteries and observe proper connection polarity. Use the controller settings and connectors appropriate for the device or battery being charged to ensure safe and efficient operation.
