    Since the Knightsbridge one can't be switched off (the MK version one can), would it use much electricity over the year since it's always in "standby" mode. Or would the cost be negligible?

    Pretty 'negligible'.

    However, it can be argued that leaving any sort of power supply permanently powered could well shorten its lifespan and, at least theoretically, could be said to represent a (tiny) fire risk.

    Kind Regards, John

    Most Fire Brigades advise that appliances should be switched OFF and not left on Stand By as there is a risk of fire when the device fails. Lack of ventilation for cooling increases the riskk of failure.

    Having a Switch Mode Power Supply module installed in way that prevents it being turned OFF ( other than at the Consumer Unit ) does not seem sensible to me.

    They would. They'd probably also like to advise that all appliances should be enclosed in 'non-combustible' enclosures when they are on!
    For those who are concerned about exceedingly small risks, it probably is not 'sensible'.

    My (electronic, but 'dumb') electricity meter must contain some sort of PSU (to power its electronics) (I suspect SM) and I can't turn that OFF, even at the consumer unit - and I imagine tat the same it true of yours.

    Kind Regards, John

    Thanks for the photo, links and info.

    I was thinking of installing one on each side of a double bed. The MK socket switches off when the cables are removed, and there there may be some slight safety improvement in this; however, it has just the two USB outlets (not 3 or 4 as per Knightsbridge and others).

    Presumably 2 USB outlets per socket is fine for most people i.e. charging a mobile - I'm not sure how many other devices people are charging via a USB socket.
