Our kits that include a USB power adapter ship with a standard EU plug. We do not include UK, AU, or other regional plug adapters in the box.
However, all our devices charge or power via micro USB or USB-C, so you can use any USB power adapter you already have at home — a phone charger works perfectly.
If your kit includes a soldering iron, it also uses a standard USB connection for power, so any USB adapter will work regardless of your country's plug type.
