2022 Upgraded Version Whether you’re RVing, camping, or powering your home in an emergency, the SP200 solar panel draws power from the sun and can charge your cell phone, iPad, or power station at the same time via the USB port. When folded, the solar panel area is reduced by 3/4 and takes up very little space. It is a compact and powerful monocrystalline solar panel with a high 23% conversion rate. Multiple Panels to Increase Charging Power Use parallel cable (need to prepare yourself) to connect 2 SP200 200-Watt solar panels to generate 400-Watt of power, which can quickly charge your power station in less time and provide more energy for your trip. Note: When using the parallel function, the output power of the solar panel is affected by the input power limits of the different power stations.
