Just wondering ......

[Murdoch]

Cards on the table - I don't like 2G sockets with integrated USB ports.....

But....

More people are asking for them....

So does anyone know if you can buy them with a switch to turn them off?

Thanks

Hamilton used to do shuttered one but don't think I've seen them with a switch.

Why the dislike?

Murdoch,

Do you mean a switch for the USB, or for the 13A side?

 

[roys]

Funnily enough I am not keen on them either, but I can see their usefulness so I put a back box on one with a gland and a short bit of flex, sits on the breakfast bar and can be switched off when not in use.

I am guessing here that no current flows until you plug something in .   I base that on us living a green , waste no energy climate now .

As long as they are made to the relevant  standard whats not to like. ?

can you stick 500V on the legs, if not - another pain when testing. Only fitted two as I have managed so far to talk clients out of using them as they were bulky. However I have noticed they are slimming down and have already been asked to fit some on a new build.......

 

[Blue Duck]

I have some at home and they have saved me from throwing Mrs Duck in the lake for discarding my charger in favour of hers! 

It's just a SMPSU like a normal charger so will need disconnecting while IR testing @ 500v just like rcbo's RCD sockets, spurs, neons etc etc.

Not sure my client will accept that!

USB side

Not sure my client will accept that!

Sell it on the fact that you can charge up to four items from one socket, one USB lead in each of the USB outlets and a charger plugged into each outlet on the 13A socket.  So all your charging is done in one location.  This is how it actually works in our house, saves chargers lying about all over the place.

I've never seen a switched usb charging supply, in a BS1363 socket.

I don't like it either, as they always draw power from the supply regardless of whether anything is plugged in or not.

 

[binky]

I wonder if they will catch fire????

 

[Sidewinder]

I think some already have!

Don't start, the LFB will insist on a metal door over them!

I have an 5 port USB charger, any 2 of the ports can give 2amps, the other 3 one amp simultaneously, apparently it's smart enough to decide which of your 2 devices needs the 2 amps most, I have no idea how that works,,,,,  

I'm not a fan of the built in USB sockets either, continually drawing power all the time, and limited design availability, and mostly only 2.1amp shared, bit lettuced IMHO,

Android devices (Apple too I assume) are a bit clever in that respect, its not just plug in and off you go, the device checks the quality, voltage, current and frequency of the 5v supply before charging commences so not to damage the battery and internal components.

frequency of a DC supply?

 

[Sidewinder]

It's called ripple Rob, it is an indication of the "quality" of the d.c. supply, so it is kind of valid.

If there is a significant frequency detected then the d.c. is not "good" d.c.

IYKWIM.

 

[Rob_the_rich]

I thought of ripples, and ripple free, after I posted. My brain hertz. thanks.

 

[Sidewinder]

Rob,

Ripple free is REALLY hard (expensive) to achieve.

Most generic PSU's use a method for smoothing that is at least partially load dependent.

trying to find where I saw "ripple free DC" in the regs
