• 【Upgraded ETFE material】The solar panel charger adopts ETFE material imported from Japan, The bumps on its surface can collect sunlight from different angles, and the fine layout can make secondary use of sunlight refraction. The light transmission rate up to 95%, providing 30% high photoelectric conversion rate. Its built-in aviation grade impact resistant material can effectively resist impact. 【Lightweight and durable】Compared with the traditional ETFE solar panel charger, our flexible solar panel is lighter and thinner. It weighs only 1.67 lbs and measures 20.8x14x0.7 inches. A layer of PCB bottom plate is added inside to prevent the conversion rate from being reduced due to the internal cracking of the solar panel. It is flexible, portable, IP65 waterproof, Windproof, dustproof and has self-cleaning capability, completely maintenance-free. 【Intelligent Charge Chip】 The built-in MPPT charge controller optimizes the performance of the solar panel, generating at least 25%-30% more power than traditional PMW charge controllers. Built-in over-voltage protection, over-charge protection, short-circuit protection, relay protection and reverse charge protection to fully protect your battery and extend its service life. 【Charging Visualization】The solar trickle charger has clear indicator lights to help you visualize the working status and battery condition well at all times.
