I was wondering if anyone on here had any experience of these, either in
their socket bar or normal outlet combined form. The info I'm looking for is
not whether they actually produce the 5vdc at a decent amperage, but how
quiet they are radio interference wise when in use. So many wall warts you
can buy seem to be doubling as radio jammers all the way through the
spectrum from long wave to vhf, and all places in between. Silent ones can
be made since the one I got with my mobile phone a couple of years ago is
completely silent, so rocket science it is not, its just cheap carp design
in my view.

I had one for a while. No problem with interference that I noticed but
amperage was crap for a modern phone or tablet. I reverted back to
walmart.

I have a number of multi-outlet strips with USB outlets. I haven't taken
an AM radio near them, but VHF seems fine. I'll try and find a working AM
radio and take a look.

Amperage is a perfectly good colloquialism. Maybe not in the rarefied circles

It also hints at the magnitude of the current, 'amperage' to me
suggests a few amps.

They seem fine here. But are metal plate sockets in steel backing boxes.
Plastic may not be as good.

I have one from TLC. Two gang plate but only one socket. The USB side
drives anything I've tried. One USB delivers 2.1 amps. Total for all four,
5 amps.

You need to check the spec before buying. Same as anything, really.

Yes, there is no switching of the input power to the USB circuit - the
circuit is being powered 24/365. In the case of Brian's request, if the
usb circuit in these wall plates does produce RF interference then it
cannot just be easily unplugged.

They tend to mostly offer the low power 1A option so not really that
useful. There is one in our village hall because a wall wart might walk.

There is no guarantee which ones will be electrically noisy. The worst I
ever saw was a BT DECT phone charger which doubled as a mobile phone
jammer. Cheap and nasty Chinese chargers have a bad habit of missing out
some or all of the interference suppression measures to save cost.

Consuming power, admitedly not much per socket but a lot of tiny
amounts soon add up to a big amount. 25 million households, average
of one of these sockets per house hold (some may have none some
several...) 0.25 W each = 6.25 MW,

In the case of Brian's request, if the usb circuit in these wall plates

Most of them do to a greater or lessor extent, in my experience a
moderately RF quiet one is rare.

Not to mention the fire risk from some elctronics permenantly connect
to the mains and subject to all the spikes and crap on that. And if
it does catch fire no easy way of removing the power.

More the point is that the circuits have common components that would
fail after a lifetime much shorter than expected for a main socket. Many
of the USB circuits have electrolytic capacitors that have been
shoehorned into a tight space unsuited for keeping them cool.

I recently saw one with 2 or 3 USB sockets, featuring a push button to
turn power off and on to them, as well as the usual switches for the 13A
sockets.

I had installed some USB sockets in two bedrooms on both sides of the
two double beds.

All was well until a power cut. When the power was restored, only two of
the 4 double sockets worked on their USB ports

So they were replaced.

Then another time, when I had a need to de-energise the circuit for some
works, the two remaining double sockets never worked on their USB ports
again when the RCBO was turned back on.

It seems if the caps dry out, the USB power circuits remain operative
until the next power cycle..... then the USB ports no longer work

They do not sound to me like they are any better or sometimes as good as the
wall warts, so I think I'll shelve that idea. I came across a sofa the other
day with them built into the hinged arm rest. I guess they will appear all
over the place but the underlying driving hardware is still going to be the
el cheapo Chinese switch mode psu I suppose.

Is that actually worse than the usual wall wart doing the same job? More
likely to be damaged by bashing it, etc?

I must have dozens of the things. Some - like for DECT phones powered
24/7. Not had any burst into flames yet.

A socket is already a possible source of fire. Overloaded, poor quality,
badly tightened terminals etc. And handling lots of amps. Given it is
reasonably protected from starting a fire because of that, I'd say it
safer than an external power supply.

I've now managed to get an AM radio beside one of my mains strips which
incorporates a couple of USB supply sockets.

Listening to 909. I note some interference when I'm about 18" away from
the strip. The level of that interference is unchanged if charging happens
or not.
