Most plug in electronic devices, electrical outlets, plugs, etc, in North / South America use 110V-120V electricity.

Note that we can include an adapter if requested in some cases to plug your treadmill into a non NEMA outlet. It is best to speak to us beforehand as this is not recommended by the manufacturer, but it is possible in many cases.
If you're in need of a 220V-240V, we can convert for $149 (External Transformer for International Use) / $199 (Internal). This will be necessary if you're shipping overseas to Europe / Asia, or if you are using a special outlet in North America, including those used for washers / dryers.
