A 4 kWh outdoor power supply indicates the amount of energy it can provide over time. Specifically, 1 kWh is the energy consumed by a device using 1 kilowatt of power for 1 hour. Therefore, a 4 kWh supply can power a device that requires 4 kilowatts for 1 hour, or a 1 kilowatt device for 4 hours2. This measurement is crucial for understanding how long you can run devices outdoors before needing to recharge the power supply. [pdf]
