General Wattage Chart

 Please note that the Extreme Universal Inverter will handle no more than a 400 watt AC appliance.

Purchasing 2 Extreme 350-watt batteries will only double the time of usable power, but is still limited to 400 watts AC power through the Extreme UI.

To find out the amount of watts your device uses, simply multiply the Amps times the Volts. (Amperes x Volts = Watts) This information is usually found on the wall charging cord of the device or possibly somewhere on your device. You may have to look up your device online and find the technical specifications or read it in the device’s product manual.
