13A Outlets with USB outlets

[MikeL1]

Hi all
looking for some feedback regarding the 13A socket outlets which also have USB outlets on the faceplate, i have seen them advertised but have not physically handled one.

1. Has anyone installed these and what are your thoughts, positive & negative required.
2. Are they good quality? if so which manufacturers are the best, i am from the MK era when their products were top quality.
3. Has anyone experienced pitfalls, if so what did you find.
4. Is there the potential for the Tx to fail and subsequently damage the Iphone, Ipad etc...

Any feedback much appreciated

MikeL

Always used branded socket outlets from Denmans or CEF most are BS/EN rated but the article has got me thinking I have to admit.

the 230v side is to a bsen but not the 5v transforner and usb

Thats what I thought , the Crabtree ones look o/k though on their own look o/k though , thats probably why Crabtree have done this ....

that is the reason why ill be messing about with resistors this week to trick the phone into thinking its charging from offical so i can charge at the full 2amps

This is an interesting post. Thanks to OP for raising it!

I have never fitted any of these but have been tempted to do so by my bedside cabinet. Sad I know.... Why I haven't is twofold; no 'decent' branded ones I have come across at a reasonable cost, and due to concerns over the charging rate (as a few have mentioned here).

Would be interested to know the outcome of your attempts at deception Shanky, so please post results. Out of curiosity how do you know which value of resistors to use? Or maybe you don't know as of yet pending your experiment!

i need 1.2v on d+ and d- cores.

using the formulae for a voltage divider i found i can use a 3k and 1k resistor for each core to grnd

Bought one online. Strange considering the screw points on the sides would match up with a standard single back box, but the (what i assume is) the transformer and terminal point on the back doesnt actually fit. Not sure what to make of that.

If your charging something like an i phone there fine.
Anything larger like an ipad or sat nav and they wont recognise a charge status because there not man enough.

If you look at the link MDJ has put up, you will see that the dedicated units have physically larger transformers.
The combined socket usb outlets only have room for a very small tranny, hence the limiting charge capability.

Pedant alert... (they're) I've said it now!

Perhaps not pedantic enough, given your stated location?

Hoist by my own petard!

 

[midgetman]

it's not wall USB charger, socket you talk of but upright one, supplied by customer. fitted the other day, charged my phone OK!

 

[midgetman]

yeah 201 posts of pure drivel... time for a lie down.

First of all, thanks for the unbelievable response to my thread, 900 odd views and 40 replies....amazing
Some very interesting points raised of which i was not aware of, having been away from the domestic scene for about 24 years after moving into the offshore oil/gas industry.

My thread was created because we are looking to install as a trial these type of USB outlets in a few cabins on the platform, the response has now raised quite a few safety issues of which i am very grateful.
At present it seems the Crabtree 2 x USB charging module part no.7073 is the only one with any credibility and meets the relevant standards.
As for the others which are available on the open market in the UK, it is frightening that many do not meet recognised standards, how many are being installed on unsuspecting customers who are non the wiser as to the potential problems which may occur following installation.

So to close this thread out thank you again for the fantastic response, it was much appreciated.

I've used them a few times, I've got a couple in the office the only problems I've found is i used hamilton ones and they seem to be slightly larger than the previous hager socket, so they can be a bit of a pain in dual boxes ect.

the fronts you mean or are they just deeper?

i imagine they would be deeper because of the 240ac-5vdc transformer in there

 

[tom262]

no not deep wider, they are the ones that have the plate that clicks over to hide the screws, and there flat plate rather than a standard socket.

ok i got it working. i know from googling that i need 1.2v on both data pins to ground, using a voltage divider

Choosing USB Pin Voltages for iPhones and iPads ? Update for iPhone 5 | Voltaic Systems Blog ? Solar DIY and Device Charging

5*(1/4) = 1.25v close enough to spec that its fine

using a 3k resistor from L to D+ and another from L to D-

then a 1k from D- to Gnd/negative and a 1k from d+ to Gnd/negative.


quick bit of soldering

proof

ill have to find camera out to prove it though
