# How Many Watts Does a Leaf Blower Use?

If you’ve ever cleared your yard with a leaf blower, you know the satisfying feeling of watching debris scatter from the machine’s powerful air. But have you wondered how much electricity it guzzles down in the process? Here’s how to understand the wattage of your leaf blower so you can ensure you have what you need to power it.

## How Much Wattage Does a Leaf Blower Use?

Leaf blowers come in various shapes and sizes, from electric ones tethered to a long extension cord or powered by a charged battery to gas-powered options that give you freedom to roam your property. For electric leaf blowers, the wattage can range from a modest ~500W to a more robust 1,500W, depending on the size and use.

## How To Calculate Leaf Blower Power Consumption

Calculating the wattage of your leaf blower is a simple process, provided you have a few critical pieces of information, including volts and amps.

First, you need to know the voltage, as the power output from the blower is voltage multiplied by the current (in amps). Then, multiply the voltage by the amperes (current) the blower uses to find watts. Most standard leaf blowers in the US operate at a 120-volt line, which means the formula for electrical consumption is:

Watts = Volts x Amps

For example, a leaf blower drawing 7 amps at 120 volts uses 840 watts.

It’s worth noting that the actual consumption may vary due to factors such as motor efficiency and any additional features that can draw extra power.
