cool!

I wondered why these were not becoming more common!! Ideal! Will need to get a couple!

500 ma or 1 amp socket?

Managed to locate it, it's 600 ma

Pretty weedy & no on/off switch, so presumably is sitting there burning electricity 24/7.

I wouldn't fit ANY Mains socket unless it met BS 1363:requirements and I can find no mention of that in the listing

That is how houses catch fire.

I always suggest that you stick to recognised manufacturers.

That photo shows an iproduct, don't they need 1 amp?

Yup. My thoughts exactly, too.

Very usefull, and not sure it would be burning elec 24 hours if nothing is plugged in to it.

Doesn't it spill out on to the floor?

Really its a bit like saying that a socket that is rated at 13 amps is going to burn 13 amps all day. It will once something is plugged into it to draw the electricity. I suspect that the circuit board on these things may draw a little current but probably run all year for 10 pence.

Not if you have a basic understanding of electricity.

Of course a mains socket doesn't draw any current on it own when there's nothing attached to it. But the transformer built into this will be permanently connected & therefore permanently drawing current. That's why nearly all AC adapters get warm when there's nothing connected to them & all advice (both green & safety) is to unplug them.

Thanks for that. I guess that will help those that also missed the links in posts 5, 6 & 7. (_;)

As no brand is shown, and details are few and far between, I would avoid it like the plague, unless it's like this brand:
hamilton-litestat.com/new…tml
ukelectricalsupplies.com/Ham…htm
has the benefit of a feature of switching off the power to the transformer when the usb socket shutter is closed. If that's the one, then it might be worth a try,

If they are not up to this spec, I suppose the safer alternative would be to feed them as a spur from a circuit, and route them through a double pole switch, (rather like you would in a Kitchen or utility room to feed a washing machine plugged in below the work tops) but it's a bit of a Kludge, and a lot more work than swapping the socket!

Must be a fair size transformer on the back of that socket, so i suppose you are right and to supply 600 ma constantly, it would soon knock up your usage.

Maybe these usb sockets have a switching transformer, i maybe wrong but don't they only transform electricity when actually plugged into the device they are charging?

It's probably tiny as it only needs to supply 3W but the physical size isn't important.

It's probably only going to cost something like a fiver a year. Nothing on it's own but those fivers start to mount up when you look around at how many other devices we tend to leave plugged in.

My biggest concern would be from a safety point of view though. As in how warm does it get bearing in mind it will be enclosed in a back-box & what protection does it offer against sending 240V up your expensive gadget in the event of component failure?

I am certainly not convinced that they are actually transforming 600 ma constantly. Maybe someone who knows about electricity can explain what sort of current these would use without anything plugged in.

That's not the point... they get warm to hot, depending on the model of charger... try it!
It's the safety aspect of leaving appliances on, without being able to turn them off, and as has been mentioned why is it not rated to the appropriate British Standard like just about any other socket you would buy ?
eg this transformer containing shaver socket:
screwfix.com/p/m…30V

Avoid! Avoid!

Note that Maplins are happy to state that THIS product meets saftey requirements.

It wouldn't supply 600ma constantly, only when the item being charged is drawing 600ma from the output side of the transformer. When nothing is plugged in, only the input side of the transformer would be in circuit, so the current used would be less,

Well I know a bit about this sort of thing and whilst actual current consumption will depend on how the voltage is transformed (wire-wound or switch-mode being the obvious examples) the actual cost when no connection to load is present will be pretty much negligible. You are not going to be able to measure it with your £5 B&Q multi-tester.
Any current as such, will be dissipated as moderate heat.
With relation to the heat comment above, take your sit-up-and-beg modern laptop tranny (which will be switch-mode) if you leave it plugged in with no load there is no heat dissipation, only when the load is connected will you notice any difference.
With wire-wound trannys, the very nature of voltage present on coiled copper on the primary side will produce (via blah blah blah) moderate heat.
Any electrical device with the harmonised B.S number/kitemark will be as safe (manufacturing defects notwithstanding) as they can be.

I think exactly the point others have already made - there is no reference to it.

I suspect someone will need to go and look at one before deciding whether it's worth buying

I have some of these - work really well.

The USB charging port is "switched" - it is only activated when the flap to the USB port is lifted.

Works really well with both my wife's iPhone and my Samsung.

where can I get twin sockets with usb - don't mind paying more

These are installed in almost every hotel I have ever stayed in (here and abroad) and to my knowledge none of them have burned to the ground (_;) So I reckon we can safely assume these are safe X)

@jcooper is 100% correct, they only become active when the flap is lifted and they charge any usb device in good order, so I dont know what the earlier comments about not enough to charge iproducts is about? They might take longer to charge, I dont know I've never been too bothered to sit with a stopwatch and time them :p, I usually just plug the device in and remove it when it is charged (or IF I need to use it).

In a few years time every new build will have these fitted as standard and these are just the ticket for anyone wanting to upgrade their sockets. So heat added.

just to add a point here steve, i agree with what you say, and would like to add that any electrical work carried out in your home should comply with british standards bs 7671 and also part P building regs.
after a quick look i dont think these items should even be for sale as there is no provision for the safe isolation of the transformer.

You dont have to be part P qualified to swap out a socket, or a light fitting, or many other things (unless said socket/fitting is in the kitchen or bathroom).

electrical installations must be safe! Part P applies to fixed electrical installations in dwellings (including gardens and shared amenities in blocks of flats) and affects many of the typical jobs undertaken by electrical contractors, particularly work carried out in kitchens and bathrooms.

Stick with this
