For some crazy reason I bought a kettle from Amazon USA because I liked the look of it. I didn’t stop to think about the difference in electrical supply until it arrived. Is there anyway I can adapt it?
It will depend on the kettle, it will have the wrong plug on for a start but some stuff does have the ability to accept duel input voltages via a selector switch, or failing that will a U.S. travel adapter to U.K. Plug work, that may be the easiest way to go
DON'T just plug it in using a travel adaptor - that only adapts the plug, not the voltage. If you plug it in and turn it on it will probably just go bang (and be permanently broken) as well as flip that circuit on your fuse board.
I'm speaking from experience having moved from UK to Japan to Australia to Japan to UK again, and had to get rid of all electrical equipment each time apart from a handful of things like computers designed to be dual-voltage
To make a 110v kettle work in the UK you would need a reasonably hefty step-down transformer, which is expensive and bulky. I'd try to return the kettle if possible, or write it off to experience and get one that is designed for the UK.
It's a resistive heating element. It'll be fine. At work we run resistive heaters at the wrong voltage all the time. You just get a different running temperature. Since the heater in a kettle is "water cooled" and has a cut out switch when the right amount of steam is produced, there's no inherent danger.
Just make sure you put a 13A fuse in the plug when you rewire it (do NOT just use a travel adaptor). If it has fancy indicator lights they might possibly go bang, but it should still heat water. When you rewire it, remember that in US appliances, the black wire is live and white is neutral, so run the black wire through the fuse.
Finally, it's bound to not be CE marked, and will not have passed the same safety tests a European kettle will have passed. For those who care about such things.
