DOKIO Portable Foldable 100W 18v Solar Suitcase Monocrystalline, Folding Solar Panel Kit with Controller to Charge 12 Volts Batteries AGM LeadAcid Types Vented Gel RV Camping Boat

The DOKIO Foldable Solar Panel is a portable solar suitcase with a charge controller, designed to charge 12V batteries such as those used in RVs. The charge controller is weather-resistant, but not waterproof, with an 8-foot cable. The product can be used to charge a 12V Lithium Iron Phosphate battery with a compatible solar charge controller. The main issue reported in customer reviews is difficulties with connections and the wire that goes to the battery clips. However, the majority of reviewers are satisfied with the quality and effectiveness of the product. One reviewer praises the quality of the build for the cost and recommends it as a good way to start or have an all-in-one backup.
