10W Portable Solar Trickle Charger for 12V Batteries in Car & Boat

·More Efficient: 30% high conversion rate crystalline silicon material + 95% high transmittance ETFE material, greatly improving the charging efficiency of solar chargers, which can achieve the most ideal charging effect in a limited space.
·Built-in Blocking Diode: The charging algorithm is upgraded, and the charging efficiency is increased by 20%-30%. Provides multiple protections such as overcharge protection, over discharge protection, reverse polarity protection, etc.
·Easier to Monitor: The solar panel junction box has indicators, which help visually monitor the working status.
·More Robust and Durable: This solar battery maintainer is covered with ultra clear PV glass which is more efficient, and also with Durable ABS plastic housing which makes this solar panels charger more stronger.
·Lightweight and Portable: The thickness is only 1/3 of the rigid panel; the weight is light and it is easy to carry. Comes with a SAE cable kit, plug and play, widely used in 12V batteries and DC charging equipment, such as cars, RVs, boats, etc.
