Whether you're staying in your RV, camping off the grid, working away from a power source, or dealing with a power outage at home, you'll love the convenience of the ACOPower 200W Portable Solar Generator. It combines a 154Wh, 41.6Ah Li-ion battery with an AC inverter and can power or charge drone batteries, CPAP machines, lights, mobile devices, power tools, laptops, and other appliances and devices. The generator can be charged from house AC current or from compatible solar panels. Outputs include a three-pronged AC outlet; two 5V, 2.4A USB ports, and one Quick Charge 3.0 USB port. You'll know the status of the battery at a glance, thanks to the four-stage battery level indicator lights on the control panel. The generator is protected against damage from low voltage, over-voltage, over-power, over-current, overheat, and short circuit.
