About this item

• 💞【Warranty】1 year warranty. If you have any questions, please contact us. Your suggestion helps us improve!
• 🔎【Version Upgrade】Because of PCB upgrade and the addition function of reverse and overcharge protections, it may not be possible to test the open-circuit voltage. Don't worry, the panel is still working normally.
• 👷【Protection】The 10w monocrystalline solar panel uses trickle charging to charge the battery without causing overcharging. Built-in blocking diode prevents reverse charging without extra maintenance at night. Works even on cloudy days. As frosted surface, the panel doesn't need film protection anymore.
• 🚗【User-Friendly Setup】Features an SAE cable for simple installation—just insert the cigarette lighter into the outlet or attach the alligator clips to the battery terminals, and you'll be ready to go in under 3 minutes!

• 💦【Function】Suitable for keeping vehicles/boat battery charged during the weeks unused. No need to disconnect the battery or have someone start the vehicle periodically. The indicator light on the back can observe the charging state. And it’s waterproof, you can safely use it outdoors(After experimental test).
