Re: "Electric Boiling Jug"
Got one -- and I'm a Californian.
One of the US's little secrets is that the domestic electricity supply is actually 230 volts. Its two phase, split around ground (earth), hence the 110v outlets you see everywhere. The higher voltage appears in the kitchen to power the range (cooker) so there's many a 'merkan of foreign origin who has a 220 volt outlet in the kitchen (or, in our case, one that leads to a couple of 13 amp sockets -- the Belkins used over here are beyond primitive). We use one for the kettle, another for the toaster.
The 1.6kW needs to be watched carefully. Big Sister (aka the EU) is coming for your high wattage appliances because they're 'inefficient' (although how a kettle could be inefficient escapes me....).
