What this site collects

The calculator runs entirely in your browser. The country, appliance and wattage you enter are not sent to us or stored on a server. Your browser may remember your country and W/kW choice on your own device so the page opens the same way next time.

Analytics

We may use privacy-friendly analytics to count visits and see which pages are used. This tells us things like page views, the country a visit came from and the type of device, but not who you are.

Advertising

This site may show ads from Google AdSense. Google and its partners use cookies to show ads based on your visits to this and other websites. You can turn off personalised ads in Google Ad Settings, and learn more at How Google uses cookies in advertising.

Affiliate links

Some links go to online stores such as Amazon. If you buy something after clicking one, we may earn a small commission at no extra cost to you. As an Amazon Associate we earn from qualifying purchases. Those stores have their own privacy policies.
