Wattage Reference Guide
(Wattages listed are just approximations. Check electronic device for actual wattage)
Don’t Overload Generator
Make sure you can supply enough rated watts for all electronic devices connected to the generator. Rated watts refer to
the power a generator must supply to keep a device running. Surge watts refer to the power a generator must supply to
start an electronic device. This power surge for starting a device usually lasts between 2-3 seconds but this additional
output must be taken into account when selecting the electronic devices you plan to attach to the generator. To prevent
overloading the generator take the following steps:
1. Add up the total rated wattage of all electronic devices that will be connected to the generator simultaneously.
2. Estimate surge watts by adding the item(s) with the highest output (it is unnecessary to calculate the surge output for all
devices as they should be connected one at a time).
3. Add the Surge Watts to the total Rated Watts in step 1. Keep total load within generator’s power capacity.
