SUNGOOYUE Solar Battery Charger, 30W USB Solar Panel Trickle Charger - for Off Grid Devices

1. High Efficiency: Our solar panel features monocrystalline cells. A higher photoelectric conversion efficiency with about 20%-25% under standard test conditions. Compared to other polycrystalline and amorphous solar panels of the same size, our monocrystalline solar collection charges quickly. 2. Battery : Trickle charging is a slow charging method. When the charged battery is low, the charger initially provides high current for fast charging. When fully charged, the charger automatically switches to trickle charging mode. The charger delivers a smaller, steady current to replenish power lost through self-discharge, keeping the battery fully charged and preventing damage from overcharging. 3. Compatibility: Use it to charge and maintain rarely used vehicles, boats, outdoor electronics, mowers and more. Make sure your devices start at all times and protect batteries from long-term discharge. It is also ideal for off-grid devices such as electric fences, gate openers, water pumps, , cameras, etc., compatible with most batteries lithium, gel, AGM, flooded, etc. 4. IP67 Water Proof: The 30W portable solar panel features IP67 water proof and , which is specially designed for outdoor use and can withstand various harsh weather conditions. 5. Safe charging: The solar panel contains a built-in controller that prevents overcharging. When it is full, the controller automatically stops charging and resumes when the voltage drops. Our solar panel system will not drain your water. Included suction cups for quick installation and all cables are plug-and-play.
