Your still missing the point, isolating via the consumer unit means the complete circuit will be dead, i.e no sockets The local isolation isolates the device from the local circuit so the rest of the circuit can still be energised and used.
These devices will fail at some point (electronics always will), if your not a DIYer then you'll also have no sockets until you can get the socket front changed.
I'll repeat from a professional point of view it is not good practise to connected devices to fixed wiring without means of local isolation and I've provided more that one reason why.

I understand your reason, just don't agree.
My point is, the convenience of these outweighs the inconvenience of the very rare inconvenience of having to isolate one individually.
Even more so when you consider if transformer fails, chances are rest of the circuit will still be usable.
But perhaps let's agree to disagree. :smiley:

I've often thought about getting these. in the end I chose a 10 gang tower extension with 4 usb ports, which sits behind the AV. A better option IMHO.

It's about time that they produced a version that have a switch for the USB sockets. Even if it switches both off. I'm holding back until this type arrives. The MK version, although a lot more expensive, would be a better bet though!

Applause for the Maths kid here :smiley:

These don't contain a transformer, the voltage is changed using a switch mode PCB

In a nutshell don't buy a usb plug as your house will burn down...or are they safe to use.?
Hotels have them?

I'm fully aware and you're just being pedantic now.
Far quicker to say transformer than 'switch mode PCB' and many more can understand what I'm trying to say without me trying to sound smart :smiley:

In a nutshell... yes they're safe and have as much chance of burning your house down as a normal plug in charger.
Just get a decent UK standard one rather than cheapo Chinese one from eBay. The innards of those look a little scary.

I've seen them in some hotels.
