You must have a countertop microwave or have an older home. My built-in microwave is on it's own circuit and even my smoke alarms are on their own circuit with battery backups. A relatively small 1,000 watt microwave draws about 1600 watts of power or over 13 amps.

You are correct. There is a separate circuit for a built in over cooker microwave, but I have a countertop. - Same in the office breakroom.

Honestly, I'd seriously considering dumping them all and replacing them when you get here.

A step up transformer is a brick of a device that will 'hum' and can get warm. They aren't really looked kindly upon by home insurance companies who feel they are a fire hazard, and you can also still have some issues motors.

What sort of devices are we talking about? Standard ASDA mixers and blenders or high-end fancy gourmet gadgets?

Yes, sorry i went a bit off topic, but, as a qualified chef myself, (C&G 706/1 don't you know!), if you are talking about household kitchen appliances or even potential commercial ones, dump them, and replace them when you get here.

If one or two items are irreplaceable, the converter option is workable.
