As you're shopping portable generators for the first time, you may find yourself overwhelmed with options. Your first question will likely be "What size generator do I need?"
The size of the generator will usually reflect its power. If you need more starting amperage to get powered up, you're going to likely need a bigger portable generator.
To determine how large of a generator you really need, you can follow the formula posted below.
| Starting Amps x Volts = Watts |
The starting amperage load will be much larger than the running load, which is why proper calculations need to be made to properly size your unit.
Because every home is different, I recommend having a certified electrician do your wattage calculation.
