To calculate the number of hours a 700W appliance would run on a battery-powered generator with an 800Wh capacity, you can use the following formula:
Run Time (hours) = Battery Capacity (Wh) / Appliance Power (W)
Given that the appliance power is 700W, and the battery capacity is 800Wh, we can plug these values into the formula:
Run Time = 800Wh / 700W
Before calculating, we need to ensure that the units are consistent. Since 1 Wh (watt-hour) is equal to 1 watt (W) of power used for 1 hour, we have a proper match of units.
Run Time = 800 / 700
Run Time ≈ 1.14 hours
So, the 700W appliance would run for approximately 1.14 hours on a battery-powered generator with an 800Wh capacity. Keep in mind that this is an estimate and does not take into account any inefficiencies or losses in the generator or appliance. Additionally, as the battery gets older or if the generator has other devices drawing power from it, the actual runtime may be slightly lower.
