If I want to charge up an electric toothbrush (in the UK) which is 110
volts (as the toothbrush is from the States) then I would presume I
would require a step down transformer.
Does using a transformer to charge up a 110volt toothbrush from a
240volt electricity supply use more electricity than charging up a
similar toothbrush which is from the UK and is therefore designed for a
240volts electricity supply and therefore does not require a
No definitive answer I'm afraid, since both (presumably) incorporate a
transformer in the chargers anyway - so it depends on the efficiency of the
whole set-up. In any event, I reckon the difference would be miniscule.
Do you have a shaver socket with a 110v output option? (And which doesn't
require a light to be on all the time ... !)
Transformers are typically better than 98% efficient.Yes you will use more
electricity, but only a tiny bit more.
alot of toothbrush chargers (and similar) are multi voltage input, typ. 90 -
250 v check the one you have.
