Features

🌱 Efficient Monocrystalline Technology – Built with high-efficiency monocrystalline silicon cells and PET edging, delivering a solid 23-24% conversion rate. Even in variable weather, it keeps harvesting solar energy to charge your 12V lead-acid or lithium battery (when used with the included controller).

🔧 100A Controller & Smart Protection – The package includes a 100A PWM controller that helps manage charging, prevent overcharging, and extend battery life. Perfect for small-scale solar setups, maintaining 12V batteries, and powering USB devices.

📱 Dual USB Output + Multi-Cable Kit – The solar panel offers two USB ports (total max 5V/1A) that can work simultaneously. You also get a 1-to-5 USB charging cable, a car charger cable, and positive/negative alligator clips – everything you need to charge phones, tablets, and other small gadgets on the go.

💨 Ultra-Light & Portable Design – The panel is only 0.2cm (0.08in) thin and weighs almost nothing. The ABS frame with PET edges makes it durable yet flexible enough to carry in a backpack. Four silicone suction cups let you mount it on a windshield, window, or any smooth surface.

⚠️ Clear & Honest Usage Scope – This kit is designed specifically for 12V lead-acid batteries (and 12V lithium batteries when using the controller). It is not for 24V systems, inverters, portable power stations, RV house batteries, trickle charging, or AC direct power. Perfect for small electronics and battery maintenance – no overpromising.

📌 Important Notes – Please Read Before Use

• ✅ Compatible with: 12V lead-acid batteries only. If you use the included 100A controller, it can also charge 12V lithium batteries.

• ❌ NOT compatible with: 24V systems, inverters, portable power stations, 100W TVs, RV 12V leisure batteries, trickle charging, or AC direct power.

• ❌ Do not bend the solar panel.

• ❌ Do not use this product to charge devices that require more than 12W continuous power.

• ⚡ The solar panel delivers max DC 5V/1A via USB and max 18V via DC output. It does not support 24V power supply.

• 🔌 The alligator clip connector is DC5521.

• 🌡️ Make sure the controller is used in an environment between 0-50℃ (32-122°F). The solar panel itself can withstand -40℃ to +85℃.

• 🧾 This product ships without pre-stored electricity – it generates power only under sunlight.
