I am not keen on the USB built in sockets. You also have to be careful you don't overload them too, the rating on them is for both ports.

I'd get a three output one thats on a plug top

too late ive got them

and like the convenience but get your point

I have them all over, probably get better ones now tbf and I did wonder about the safety of them when I first fitted them a few years ago but out of probably 12 I've had 0 failures. First ones I bought (I've changed them as I've decorated) were c£30 - £40 iirc.

Agreed, not as good as the OEM charger, I think they kill the batteries faster

I feel they have far too many issues to be worth it.

A lot of them are shoehorned into the outlets free space with no thought on quality of the power supply.

Even if they supply the correct voltages from new (a lot of the cheap ones don't) as it ages the voltage will creep up and will not last as long as the outlet would itself.

There is a tiny amount of tolerance with USB voltage before batteries take a hit, cheap car chargers can be just as bad for this.

Cheaper brands it can effect the IR of the device, some brands known to make the USB ports live in a failure of the PSU.

On top of that there is also the issue you can't switch them off (from a safety or power POV) without doing so at the CU, lack of support for larger devices and/or smart charging.

In short a bad idea IMO.

Im a big fan of Buck convertors and making my own PSU chargers, that way I know my current limitations and I can change them easily. I have several echo inputs and dots around the house and in most cases I use 12vdc PSU thats powering other stuff like LED lighting or Bluetooth amplifiers, then I use Buck convertors to drop the voltage for the 5v stuff. I have a ten amp PSU in the top garage thats powering Bluetooth  in the Kitchen speakers VIA a Buck, Echo in the kitchen Via a Buck, 12v LED strip lights, and a 12v wireless receiver to switch stuff (like the lights and the speakers on and off) On the landing I have the droid pad, I have 12v dc powering a receiver and a buck , the receiver is on a timer progged by Sonoff and it switches the buck on and off so that the driod gets a couple of hours charge per day, the is another buck running off the same psu powering an input on the landing. I have voice control nearly everywhere I am in the house.Mostly powered by 12vdc and bucks

Some good points and I'll look at the o/p voltage on them just out of interest.

 

I don't like anything on show so find the convenience overrides the negatives for me at least.

There are others similar available but very useful to have one in your tool kit if your around these devices a lot, confirmed there accuracy with my multimeter initially.

 

Say you have a house full of them and you have an intermittent issue on your power circuit, there is no way to have the circuit powered with no load and no easy way to do testing as a megger would blow them all up.

It's an unlikely issue but you could add hours on to an electrical job disconnecting them all back to a standard installation before you even start looking for a wiring issue etc.

 

To the OP you will find that the closer you get to the rated output (trying to charge 3 devices) the more the voltage will sag, meaning they will take longer to charge than they possibly would if you charged them individually..

I've got the same but it has a fly lead. 

 

Anyway with the multi meter most are between 4.9c and 5.4v the one I use the most in the kitchen is 7.4v!

 

And one of the two in the daughters old room are 0v.

 

All are different makes bought at different times but all match in each room if that makes sense. 

 

Looks like I need a couple new ones. 

 

Lol

Scary thing is how much it's been raping your expensive smartphone circuitry and batteries while you haven't noticed.

@sixwheeledbeast I was looking at the same USB thingy before you posted...

 

USB sockets ? no worse than the issue with a lighting circuit with bulb, transformers & pir's ?
