Or even 2.5W, which is the limit (500mA @ 5V) for a USB device.

wonder if it'd be any good for trimming toe nails,

my brother will want one of these for xmas, he is hooked on collecting usb
powered stuff, got mini fridges, cup warmers, can coolers, a pizza slice
keeper warmer and so on.

to keep a pizza slice warm on 2.5w would take vacuum insulation! And
to heat one upon such power, if 1kW takes 1 minute for a slice then
2.5w might take 400 mins = about 7hrs.

i never said it worked, he just loves all this crap because it usb, he loves
his computer that much,

the pizza slice keeper warmer thing is just a hot plate, same as the coke
can cooler, just long triangle shaped and the peltier is run in heat on top
mode,
but useless even if it did work, as all it'd do is keep the base warm, i'd
want the topping kept warm.. but hen again i can eat my pizza's before they
get cold, i guess his go cold as he's too busy wanking over lara croft and
forgets about the pizza.

Update. Apparently, a lot of desktop motherboards scrimp on components
by only applying an overall current limit across all the USB ports. So
if you have, say, 4 ports, you can pull 2A from a single connected
port without tripping the overload detection.

Laptops, I'm told, adhere more closely to the USB spec.

Ah, but you simply have a huge slab of steel inside a load of
insulation..like a mini aga. And leave it on 24x7.

That rather depends on whether it has a battery in it and what the duty
cycle is. I mean, in typical office life you won't want to use a
chainsaw for very long in any given week.

Where do you get 5W? USB is 500mA max per port at 5v = 2.5W. B-)

Web page is broken in some peculiar way so can't see it if does use 2
ports or not.

I thought that as well - but a Wiki check revealed:

"In Battery Charging Specification, new powering modes are added to the
USB specification. A host or hub charger can supply maximum 1.5 A when
communicating at low-speed or full-speed, maximum 900 mA when
communicating at hi-speed, no upper current limit when no communication
is taking place. A dedicated charger can supply maximum 1.8 A of
current. A portable device can draw up to 1.8 A from a dedicated
charger. The dedicated charger shorts the D+ and D- pins together and
will not send or receive any information on those lines, allowing very
simple, high current chargers to be manufactured. The increased current
(faster charging) will occur once the host/hub and devices both support
the new charging specification."

Hypothyroidism is a seriously debilitating condition with an insidious
onset.
Although common it frequently goes undiagnosed.

Even so, it's hardly going to cut down oak trees, is it?

And do you *really* want sawdust within one USB cable-length of your
computer?

Wonderful invent a "standard" then break it. Older kit expects to be
current limited to 100mA unless it asks for and is granted high
current. I've got kit here that charges from USB and gets decidedly
hot on on some "USB" charging ports but not when connected to real
USB ports.

Probably no worse than the grease laden flakes of skin and clothing
fluff that gets inside anyway.
