3.1A output too, great price
Cheap. Problem is (as with all these USB wall sockets) that the usb bit is always on, unless you turn of complete circuit. They tend to expire after a while, and, of course, are always using some electricity.
I really advise not buying these USB wall sockets.
I’ve had to replace 2 out of 5 in the space of a year. The idea is good but they wear out quickly.
They're cheap for a reason...bought one less than 12 months ago and the usb socket has broken with light use! Don't know if it's a safety risk but wouldn't buy another. Spend a bit more on a better quality unit. Any advise on which one would be appreciated.

Out of interest why would these always be using electricity? Where would it go? Thanks.

The transformer for the usb ports would always be live, therefore it would always be using a little. Same as a charger for your phone, if left switched on it would always be slightly warm, not as warm as when charging, but still live. If you put your ear to a switched on but not charging transformer you should be able to hear a slight buzzing, about as technical as I can get!

Because they are always on. They can also develop faults.

We are talking here about usage of not more than 100Wh so just to give you a rough idea - in one hour you use 100W of energy, month has circa 720h so you use 72kWh per month. Cost of kWh is about 13p? So that gives u about 9 pounds a month worth of electricity bill.

You can always look for something like this product has little spring-loaded doors on the USB ports that completely shut off the power supply when they’re closed.

No, I generally get rid of receipts after a month. Bought theses from screwfix and wickes, so expected them to be of good quality

Need these sockets with quickcharge
Are these made to BS1362-2:2016 +A1 ??

Hi, not sure about the maths here. I don't know the exact figures but 3.1A at 5.5V is 17W, allowing for 80% efficiency gives a peak power consumption of 21W. If you ran these 2 hours per day on average, and allowed 5% maximum for idle consumption it would be about 66W/hr per day, 24Kw per year at 13p is just over £3 per year. so not frightening but they do add up if you have lots of them drawing power. Also bear in mind on these figures £2 is charging your device, £1 is leaving the charger powered up.

But you are talking about secondary side of a transformer aren’t you? The primary side is supplied with a 230V before it’s being dropped to ELV - it’s like with the phone charger After all isn’t it?

So what is the real answer, how much does it cost in 1 year if the usb wasn't used

Sure, power out/power in is the efficiency. You lose a certain amount from the conversion from AC to DC, then a certain amount reducing the voltage, I would guess you would lose no more than 20% using a decent power supply. Remember 3A out at 5.5V DC is less than 0.1A in at mains voltage. Also the figures I gave would be enough to charge 2 phones, though they would take less for longer in real life. Remember these losses turn in to heat, if we were losing 100W it would be a very hot socket, but it would help reduce your heating bill, it all has to go somewhere. If you touch these sockets when they are not being used they should be cool, if they are hot I would replace it as it is costing you money and potentially poor quality. This isn't my field but i understand power, I think.

lol I have had them installed in mine for well over a year no problems, they wouldn't pass electrical regulations etc and be sold if they were a danger.
Now I know you can always buy crap makes, not saying these are I expect they are fine, but I have MK ones cost abit more but great quality.

I just don't see the advantage over a removable one.

It saves you a plug socket that's the ideal ....you can even get them with built in WiFi extenders now as well.

Agreed but it looks ugly as hell ......depends if you want that tidy/modern look I guess.
Plus they are designed for backboxes in the wall not surface mounted.

They come in white, too.

Oh they can be used surface mounted or back boxes Inthe wall, I'm sure. That is an irrelevance.

They may come in white, still looks too bulky and obtrusive for my liking, but we all like different things.
Look they clearly aren't designed for you and your property, so not sure why we are discussing it.
Have a good weekend, cheers
