Calculate Your Battery Duration with Our Easy-to-Use Online Tool
You can find this information on the appliance itself or in the user manual, or you can use predefined values for common appliances that you'll find below. Some people use a power meter to measure the power consumption of their appliances.
The most common battery voltages are 12V and 24V for cars, motorhomes, and boats, and 48V for solar systems.
This can be the conversion efficiency of your inverter if you have one, if not just make it 100%, typical values are between 80% and 95%

Here are the results for your battery usage with an appliance consumming 100 watts.

Amperage draw: 9.26, you're battery must be capable of suppling this discharge load, see more about it below.
