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 transformer?Thanks!
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 ... !)
Simply buy a bathroom socket. They are 110 > 240 volts.
Plenty of shaver sockets have 110v and 240v sockets eg
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.Ian
Unfortunately no there's no shaver socket in the bathroom, so the toothbrush would have to be charged in a bedroom.
Thanks very much for the link, I'll check it now. Thanks!
