Choosing A Generator

Make a list

Designed from the ground up, GT Power has studied the Kiwi lifestyle and New Zealand conditions, and have curated a range of portable, versatile generators that suit the way of life that we live and love. GT Power has matched their models to suit the tasks that you do most. With generators ranging from 2000W to 18000W, GT Power has your portable power needs covered.

Note the wattage required

The list below offers a guide on the wattages used on most common appliances and items used at home and in the workplace. For exact figures we recommend you check the nameplate or instruction manual for your individual appliances. Also listed (where applicable) is the “starting wattage” or “surge wattage” which is the amount of wattage needed to start an appliance with a motor. This may be up to three times the wattage required to run the appliance, so this must be taken into consideration.

All generators also have a maximum and rated wattage output. GT POWER Generators are designed to work at their maximum rating for up to half an hour. Rated power is the level where the generator can be operated continuously and is typically 90% of maximum power.

Calculate your total power needs

This chart lists average power requirements. Your particular tool or appliance may require more or less than the listed wattage. Firstly, add up all the “running wattage” requirements for all the items that you need to power simultaneously. Next, add to that total the highest of the “starting wattages” you listed down. Now you know approximately how much power you need to start and run your appliances and equipment.
