Calculate Your Power Needs

Before you start comparing models or shopping prices, we highly recommend to first identify your power needs. This helps you select the portable generator that is right for you. You may start by using our Wattage Calculator to calculate power needs. You can then you can select the category of portable generators you may need to buy.

To do so, start by looking around your home and figure out which appliances or gadgets you really must have when the power goes out. Write down everything that uses power, and put them into 2 groups:

1.    Must-have items (like your fridge and lights)
2.    Would-like-to-have items (like a dishwasher)

Once you've done this, use our wattage calculator to total up total power needed.
