Masterplug GV White USB Socket Twin Pack. 558/6220

Pair of double mains sockets with 5v 2.1A USB's.

Not sure how great the USB charging is on these or any others on screwfix, toolstation etc.
But these are branded and work out cheaper per item than most other places. ( if you need 2)
At Argos too, so pretty easy for most to get.

Hope it helps someone..

anyone know if these are vampire sockets, eg still draw power without anything plugged into the USB like a lot of other cheap models?


​Yes they only work at night

yes they will still draw a small amount of power and the low voltage side will always be energised.
what are we looking at (cost wise) an extra 50p a year?
you need to think about the fact you have an non isolated load permanently connect to your fixed wiring rather that the electricity cost.

Yes, good price if you want two (and why not?).

I bought a similar one from B&Q Tradepoint for £6, but Argos is a better option for most.

good find op, heat added

thats great iam happy

Looking at the picture it looks like it's a shared 2.1a output. So can only charge one device at 2.1a?
#5
I purchased these recently and they are very good and sturdy, however it is a shared usb output, 1 device = 2.1a, 2 devices = half the listed output
#6
Will I be able to use these to replace existing plug sockets that are not in the wall as such. i.e. not flush. Instead they have the box mounted to the wall? Sorry a bit of a novice when it comes to electrics...

The charging speed is pretty poor on these. It's ok if you leave your phone charging overnight. And I wouldn't go round the house changing all the sockets, I only changed one of the sockets which was congested with other plugs.

There are quite decent chargers now which come with the mobile phones which can give you a full charge in half an hour.

​Strange. Charges my s6 edge plus in about 2 hours. are you using the right USB socket?

​2.1a x 5v = 10.5w
8760 hours (per year) x 10.5w = 91,980Wh
91,980Wh in kWh is 91.98kWh...

91.98kWh seems really excessive, can anyone confirm? that's a lot of power over a year for a poxy couple of USB ports.

​That's only if something is permanently charging at 2.1 amps - in standby it should be far less.. (don't know what though.)
Electricity costs around 10-15p per Kw, so looking at max. annual cost of £13 ish...

Masterplug are a semi decent brand, personally though I'd only fit the MK variety but then again I wouldn't fit any non isolated device onto the fixed wiring of my house especially (as in your case) you not a DIYer

They will work fine with a back box you've described but bear in mind that carrying out home electrical work yourself when not a qualified electrician is now illegal and if something went wrong (Which by your own admission to being a novice is possible) your insurance company would void any claim you make should anything go wrong

No as a phone charger can be unplugged i.e isolated.

The point I'm trying to make, if a device is permanently connect to your fixed wiring (without isolation) and that device faults then you potentially have no sockets until that device is repaired/replaced. These USB sockets contain a PCB with electronics, electronics do and will eventually fail. In that case then the socket front would need replacing, not a big job but if your not a DIYer this potentially leaves you with no sockets and in the hands of an emergency electrician with all the costs associated with that.

I would only fit MK sockets as well but they also split the current available for the USB sockets in 2 resulting in a measly 1 amp per USB. So has anyone come across a USB double that does better?

I don't think there is it would make the back of the socket too large due to a bigger switch mode power supply and a very deep back box would be required.

bear in mind that carrying out home electrical work yourself when not a qualified electrician is now illegal and if something went wrong

The regulations allow changing of accessories (such as switches, ceiling roses and sockets) as non notifiable, almost anywhere in the house, except a special location (notably kitchens and bathrooms).

Yes there are issues with them being always live, but it would be a very very harsh judgement for someone to be prosecuted for swapping a standard socket for a USB equipped socket.

I don't think you'll find it. Some new versions are saying 2.4A but I believe it's the same thing just playing a bit with numbers.

I installed a couple of these in my house last week. Charging time is not too bad at all. Product is good but had a slightly cheap feel about it. Good price for 2, well worth having a couple installed.

With regards to the constant power supply, I'm sure I seen something about it detecting when a device is full. Im assuming it would put the power supply right down to only detect a non full battery?

The power consumption with nothing attached will be minimal but you still have an electronic device (PCB) permanently energised and connected directly to the fixed wiring of the house with no means of local isolation, not good practise.

Same thing applies to doorbell transformers.

It even applies to TVs, Sky boxes etc where often the isolating socket is behind an AV unit and not easily accessible. Essentially these are also non isolated loads in practical terms.

I think the restriction here is the size of the transformer and heat if you were to draw 4.2 amps in the confines of an enclosed backbox.

no and no

A door bell transformer will be wired through a fused spur unit and anything plugged into the front of a socket (TV in your example) can be isolated by unplugging, restricted access behind an AV unit is not an issue.

Local isolation is important for many reasons but mainly isolating an item in the event of it being faulty and disconnecting it from the rest of the circuit (so you can still utilise the circuit), it's also very important you can isolate easily for periodical electrical testing (when moving house, having notified work done etc.) As these USB sockets are PCB's connected directly to a fixed wiring system there would be no way to perform a required insulation test without physically removing them first.

Totally agree with you but it will cost more than a fiver more. They're currently (like that) on offer for £20 for one. So I think overpriced considering you can get a twin MK skt for £4. :)

It's done properly by MK and there's an integrated transformer unit as well, it's a lot more than just a simple twin socket.

How many times a year does the average household do an insulation test? Not really worth worrying about.

By the same argument if you really needed to you can isolate one of these you can just do it via consumer unit.

Most people worry about if these will burn their house down not if will they need to be removed when doing an insulation test - so my argument of other permanent live load present around the house stands.

My point is there are other permanently live loads in other places. Just because these are built into the socket doesn't necessarily make them bad - unless there's a genuine safety risk (not just an inconvenience factor once every five years).
