The runtime of a solar-powered generator varies depending on its battery capacity and the power consumption of the appliances connected to it. Smaller models with lower wattage and battery capacity might run small electronic devices like smartphones and laptops for several hours. On the other hand, larger and more powerful generators can run essential appliances like refrigerators, lights, and fans for extended periods. To estimate the runtime, divide the generator's battery capacity (measured in watt-hours) by the power consumption of the connected device (in watts).
