Feature: 1. Bill Free Solar Panel Kit --- Monocrystalline solar panel and environmental PET film, safe to use with long service life. Environmental conservation solar energy, bill-free and user-friendly. 2. High Conversion Efficiency --- With high efficiency monocrystalline solar cell, you will get greater power efficiency even though the panel is smaller than a traditional model.Maximizes system output by reducing mismatch loss. 3. Portable Design --- Small in size and light to take, it is easy to carry for camping or other outdoor activities. Easy to install with pre-drilled holes on the back of panels for fast mounting and securing. You compact size is more convenient to place under your car front window. 4. Plug and Play \u0026 Longevity --- Built USB port in the solar panel, come with 4 kinds charing cable, fit most kinds of device, plug and play, avoide out unexpected off power. Advanced water and dust proof level, complete conservation against environmental particles and low pressure water jets. 5. Wide Application --- Widely applied to off grid 5/12 Volt battery charging system and a variety of DC applications, including caravan, RV, car, boat, green house, marine, dry camping, garden watering, shed, cabin, gate opener, etc. Specification: The 12W Solar Power Starter Kit charge with DC 5V/12V output and IP65 water resistance. The Starter Kit is great for off-grid applications, such as RVs, trailers, boats, sheds, and cabins. With a controller to control the batterys voltage and turn on the circuit. Adding a polycrystalline or monocrystalline solar panel kit can extend your travels further than ever before.
