On appliances there is this little sign that reads: X Watts, where X is a number which becomes progressively larger as the years go by. Have you noticed the power hungry irons, vaccum cleaners and hair dryers of today?
Philips irons now boast 2400W. My iron is half as powerful and still does away with the wrinkles.
Miele offers 2100W vaccum cleaners. My old vaccum cleaner is a thousand watts behind and clearly bites the dust. Blissfully ignorant of this, it cleans my floor without complaints.
Braun joins the power struggle with a 2000W hair dryer. Will the user experience it as a sensation or a burning sensation?
Not to be outdone, the electric tool manufacturers introduce 2200W angle grinders. The lastest trend in work out, maybe?
Yes C-H, You're not alone in noticing this trend of increasing nameplate wattages. Being a person that used to service/repair a lot of home appliances, it was always interesting to actually have a look at the attached nameplate. Heaters here are usually rated at the maximum that you can plug into a standard socket-outlet (10A), which gives you 2400W, which is a little worrying, considering that these appliances are invariably made with a plastic body these days. I've also noticed in the various DIY brochures that turn up in my mailbox, the power tools are actually advertised, with thier power ratings seemingly the most important feature of the tool, what good is a 900W Drill if the user can't handle it? Vacuum cleaners are really rediculously rated here, I mean a 2200W vacuum, must surely be referring to input power and of course once you've used it a few times, expect the suction to be less!.

uksparky, I wonder if you can use the hairdryer as a hot air gun? Perhaps Braun's numbers are just a lot of hot air?
Yes, Mike, it is always input power. Thus, the less efficient the machine, the bigger figure to boast on the nameplate. I once sold vaccum cleaners among other things and a key selling point was to point out that the actual suction power of the vaccum cleaner was higher than cheaper competitors despite a lower nameplate wattage. A vaccum cleaner puts out maybe 300-400W of actual suction power when the nameplate reads 2000W. In other words, it is primarily a very noisy way of heating a room. Cleaning is secondary

Hutch has already mentioned the kettles of up to 3kW that no British kitchen would be seen without, although most of the newer plastic jug-style kettles seem to be more around the 2kW range.
The other appliances in the U.K. which have traditionally had higher ratings have been portable heaters. You could buy single or twin-bar heaters rated at 1 or 2kW, but portable heaters of up to 3kW maximum have been quite common here for many decades. It's said that the 13A rating of BS1363 plugs was chosen specifically to allow appliances of up to 3kW.
Good point about the input power rating of vacuum cleaners. Most people don't understand anything about efficiency and just automatically assume that a 1200W unit will have better suction than an 1000W one.
(I nearly said "suck more", but that could be misinterpreted! ).

Paul, Interesting to note about vacuum cleaners, that most of the losses involved in a cleaner is caused by the air path through it. Therefore, if you took out the bag and the air filters, you'd have somewhat more suction. Sure the motor probably wouldn't last too long and you'd have to be Hercules to move the head over the floor, but the cleaner would be more efficient. One appliance that has seemingly escaped being turbo-charged, is the humble toaster, I've got a relatively new one here and it's only rated at 300W, it can blacken toast like you wouldn't believe though!.
