Operation
Equipment Power Usage
It is important to use only products that draw less than the power
rating of the power inverter. Use of products greater than the
rated power rating may either cause the protection circuitry of the
power inverter to shut down or the fuse to blow. Repeated use of
excessive power draw can cause failure of the power inverter.
How to calculate power usage. Most products have a power
rating on them such as 45 watts. Others may be marked with
their current draw, such as .9 amps. To convert the current to
watts multiply the current by 115. (Example: .9 amps x 115 =
104 watts)
