How much current can they deliver I wonder? If they are standard wall socket
sized I'd expect it to be less than what a real charger or power supply can
deliver.

Usually 2 amps Brian - shared it 2 sockets are used.

I wouldn't like to count on that if its a timber framed building.
The external one would at least have a fire proof layer between it and
the frame even if its only plaster board.
It would also set off the smoke alarm well before the fire took hold.

The one I have is an expensive flat plate one from TLC which matches the
other sockets in the room.

It has four outputs. One is marked as 2.1 amp. The other three 3 amp total.

It may have been expensive, but looks so much better than the wall warts
that were there before it. It's in a place which is very convenient to use
as a charging station, so not buried away. Which makes it pretty visible.

My phone is over a year old and it wants 3A, so the inbuilt chargers are
out of date before you start, other phones/tablets with quickcharge want
9V or 12V, I believe the maximum of the current(!) USB spec is 20V @ 5A
which some macbooks/chromebooks can take.

It's usb pd (power delivery). Compatible devices can negotiate current/
voltage levels with the charger, up to 100W. My HTC 10 gets a bit sulky
when plugged into a charger that refuses to talk to it.

FWIW I think they are a horrible gimmick. They will permanently take
power even when you are not charging anything - albeit a small amount.

I leave my discreet ones plugged in all the time
anyway, because that is the most convenient.

I believe it is best practice to disconnect
electrical items when not in use.

You're wrong with high efficiency switch mode stuff.

Okay, I was unaware of that.

Eventually the smoothing electrolytics will blow

By that time they may well be obsolete anyway.

So why physically install an appliance

It isnt an appliance, its just a wall socket.

Okay, I wondered about the word as I typed.
My dictionary includes 'apparatus' as a meaning,

But clearly doesn't include say an extension
cord or the socket in the mains wiring.

but I accept the usual usage is
electrical goods rather than wiring.

Not just the usual use, the technical term too.

that will become obsolete. Use a portable one instead.

Can be more convenient to have one with 4 USB sockets
so you can change multiple devices simultaneously.

potentially causing a hazard.

Not if buy a well designed one.

People used to think Samsung
and Hotpoint were well designed.

And those with even half a clue know that Apple chargers
are and can check teardowns on that to see that they are.

???

There are teardowns on youtube.

I thought Apple had a recall at one stage.

Not with a mains charger because it was potentially a hazard.

Brian Gaff wrote

Plenty of them can deliver as much as the wall wart style.

If they are standard wall socket sized I'd expect it to be less than what
a real charger or power supply can deliver.

That is just not true with a switch mode charger, the size
doesn’t vary much with the current they can supply.

They aren't switcheable (the ones I've seen), so small
power consumption is guaranteed. And if ever you have
your circuits mega'd, they'll probably be fried.

You require a cabinet reshuffle. Can't have minor ministers running the

It wasn't really that difficult to do. If I were doing it now, I might
decide to hang on until usb-c models become commonplace, or even
available - are they available now?


There's the problem - USB vX.Y is obsolete before you can cough (every
2-3 years IME for a new higher power version comes out).

So stick to wall warts
Surely an essential reason to buy some new hifi technology, that also
has a USB charging outlet built in :-).

Hmm.. Having just taken down some internal studwork walls (timber frame

That won't stop a fire once flames reach the studwork.

Hmm.. again:-)

I light a log burner most mornings at this time of year. Nice little
conical pile of mixed thickness sticks, small logs selected from the
basket inclined in a tepee. Full draught from the grate and then.. at
least 30 seconds of the creme brulee torch to be sure of not having to
start over.

I don't see the let through energy of a 32 amp MCB being anything like
this. Glass wool burns/melts but only under a sustained hot flame.

For Toyota it's about $250 per update, which (for some) comes on a DVD you
insert in the head unit. Some of the ~2007 ones have a dedicated DVD
nav unit (ie the maps are read off the DVD when navigating, they aren't
copied elsewhere). Given the price, the DVDs are widely counterfeited.
It's easier for more recent cars, but this gives you an idea what it's
like 10 years down the track.

Things like Android Auto have the potential to be more sane - the car is a
screen and peripherals for a phone. In principle that means you can easily
upgrade the phone as technology improves. There's also CarPlay (Apple) and
MirrorLink (Nokia, Samsung, Sony) doing similar things. All of these are a
bit too new to see what happens when they go stale after a few years.
(at the very least, having competing standards means you can't easily switch
phone vendors)

Interesting. Mate has a timber framed house bought new which I've done
some work on, and the boxes there are all ordinary ones. Usually nailed to
a stud with clouts.

They are arguably rather better than any alternatives. Which are few and
