its 3.1A shared so wont charge 2 modern devices at full speed

2.1A, not 3.1

OK. That's the only one at £8.99 on their website.

There's also a metal one at £14.99 but it's also 2.1A.

Ops post is in store - not online.

Yes sorry in store. Pic is of my actual plug which says 3.1a

I wonder if someone in 30 years will still have USB sockets in their home and people will be like wtf are those little ports for :stuck_out_tongue:

Screwfix are doing the 3.1a sockets 2 for £18..

Just make sure it is CE marked. A lot of these cheap ones don't and won't meet minimum safety standards. Dangerous item to have unfused in your house circuits if there is a chance it could go wrong.

Unless the USB ports are active then it can't be USB 3.1, it's just a charger, I suspect 3.1 Amp is what is meant there.

I have to say I would be weary of having a USB device which directly wired into the mains and on 24/365.
Plus, really if they were trustworthy and worth having, then USB C would make more sense as normal USB A sockets aren't exactly known for their robustness or longevity.

Separate USB sockets for greater flexibility and faster charging. Ideal for for smartphones, tablets and cameras.
BS1363 Pt2 BS5733. 2 x USB (1 x 2.4A, 1 x 1.2A)

Slightly more @ £10.78, but dedicated USB ports, not shared.

It's shocking how much they charge

Seems unlikely USB A will last too much longer for the particular intention here. Charging mobile devices with USB C is slowly but surely becoming more common. USB A will still be around a bit yet, but mobile devices evolve so fast I'll be surprised if anyone is using USB A style cables for charging in 5 years time let alone 30.

USB A is going nowhere its too widely used, C is ok for the connector, but its a USB C to A cable you use for charging.

Its Micro USB that may well disappear in the next few years..

In 1986 I was using a few different computers, the fastest of which had a 3.5Mhz Z80 CPU with 48K RAM. There were no web pages and I had to write my own terminal program to interface with a 1967 Jacobsen Anderson acoustic coupler at 300 baud and dial up various BBS's that I found in the pages of Micromart and I had to view it on my CRT TV with a very poor resolution. The TRS 80 Model III that I also had, did have a CRT monitor built in with a resolution of 512 * 192. It also cost £5,000 with the software suite my Dad got with it at the time. Potato times.

30 years later, my phone has everything better than those computers, and includes a myriad of sensors those computers never had and I have access to an encyclopedic wealth of information. More has happened in the last decade than in the last 30 years, the speed of technological change is massive.

USB A will be long gone in 30 years time and some people will remember it and say oh yeah there's that crap USB A we had to deal with 30+ years ago, and they'll laugh when they see the old adverts from 2017 showing off the latest Galaxy S8 (to be released soon) which will not even measure up to a potato in 2047.

Unless a large disaster happens to mankind, those of us who are left from this time will even laugh at the technology of today, no matter how great we think it is today.

USB A is nearly dead already. I can see a day already where we'll be yanking out these 2 gang USB plugs in favour of USB C and then yanking those out in favour of the next thing, well before 30 years has elapsed.

The actual place where technology for all its power is lacking is in medicine, we can't cure serious illnesses such as Cancer completely, the answer to the common cold eludes us and we're on the brink of a natural disaster involving antibiotics just because morons insist the doctor give it to them for a viral infection, most of us have been that moron and many of us still are, we are running out of effective antibiotics, when that happens, we're in for a very bad time. We can't cure trivial complaints such as baldness, because our current techniques of scientific study haven't evolved radically enough.

USB A to USB C is only used because USB C is not widespread enough just yet. When it is, USB A will be pretty pointless for charging and will likely be rare in an application such as this.

You can charge/power most anything common with a C to C because they can support 100w. You can charge laptops which are inclining to the USB C standard. This bodes well for the future of fast charging other small devices too which is mainly the point of this.

USB A then is likely to be gone for charging long long before 30 years are up!

Just picked up a 2 pack of double sockets with USB 2.1A output for £9.99 at Argos

What devices can actually charge at 3.1A? Genuinely curious.



It seems like a bit of a marketing con to me. Fit a 3.1A transformer and share it between 2 ports then call them 3.1A ports.



It sounds much better than 2.1A ports when infact the 2.1A could have a total of 4.2A shared.
People see 3.1 and assume its better than 2.1.

You could have a 50A charger but fact is the device will limit charge current to 1 or 2A.

There is no USB C standard, its USB 3.0 and 3.1 USB B Type A Type B, Micro, Type C etc are just the connection types.

I'm getting quite weary with people who can't spell "wary". :smiley:

But I didn't say otherwise.

I just said that USB C is actually being used and picked up for charging which means it'll probably become the usual within a couple years at both ends. Essentially that was precisely what it was designed for anyway: to replace both ends eventually and not just one. It's getting there but you need the device support first and that is growing rapidly.

USB C to C, nice easy (smaller) sockets with reversible orientation. Be happy about it. It's better. Probably be lucky if USB C is common in 20 years let alone USB A!

Which really is the point. As fishmaster said, be lucky if youngsters even know what USB A is :stuck_out_tongue:

USB A will be like an old pc printer port, that's right kids... We used to have a dedicated printer port, which was color coded pink in the end :sunglasses:

So these don't support far charging, right?

I have seen electrical stuff in Poundland without CE marking.

Surprising, as stamping a CE mark on something is the easiest thing to do and means nothing at all.

Some people will still have the sockets in their homes in 30 years, might not be used. If you look at houses for sale you still see decor and appliances from the 70s in some of them.

Medicine probably can cure more than they let on since it is more profitable to treat than to cure.

Baldness depends on the cause. But hair transplants, propecia, rogaine and ketaconazole can restore the look and prevent further loss in male pattern baldness.
