10 W polycrystalline solar panel with two 5 V USB outputs — durable, easy to integrate power for 12 V systems and USB devices. Key benefits Reliable small-scale solar power: 10 W polycrystalline panel with a high conversion rate provides steady charging to reduce energy costs and lower reliance on grid power, supporting sustainable use. Long-lasting, weather-resistant design: aluminum-alloy frame and coated safety glass protect the cells; IP65-rated protection resists dust and water jets for outdoor use. Simple integration with 12 V systems: designed to work with various 12 V batteries for charging or maintenance—fits into existing off-grid setups, vehicle systems, or emergency kits without complex modifications. On-the-go device charging: two 5 V USB ports allow simultaneous charging of phones, tablets, or other USB-powered devices—eliminates the need for extra adapters or wall outlets when sunlight is available. How it solves problems Keeps batteries topped up to avoid dead batteries in vehicles, cabins, or backup systems. Provides immediate USB power for essential devices during outages or while off-grid. Reduces dependency on grid electricity for small loads, lowering running costs and environmental impact. Robust construction minimizes maintenance and downtime in exposed outdoor locations.
