Goldie is designed to work internationally!
Goldie uses so little power (under 5W) that it runs via USB, which works with a wide range of power regions: 100~240V, 50~60Hz.
You can power Goldie by plugging it into a USB power outlet, or by using a USB-to-wall adaptor that fits your local power outlet type. If you live in the US or Canada, an adapter is included with Goldie.
