I have an American razor, seen in the first picture, that is marked as 120V ~60HZ 12W.

I went to Belgrade and bought an coverter, seen in the second picture, with output of AC 110V and 45W. The razor worked, but it was clear that too much power was going to the device, as the motor was running very fast and very loud. It actually hurt my ears, but I used it anyway.

Now I'm in London and I bought a new converter (picture 3 and 4), hoping to be able to use my device normally, that is with the proper amount of current. The box says it has an output of AC 110V and up to 100W. Is this thing going to blow my razor? What do I need to buy to use this thing properly?

EDIT

I'm using Airbnb's so would need a solution for a regular UK household.

Also, this is a hair clipper that plugs directly into the wall. No battery involved at all.

The wattage on the converter is the maximum it can handle, it's not physically possible for it to supply your razor with more energy than it needs.

The change you experienced in speed and sound with the old converter must be due to something else. Given my (admittedly limited) knowledge on how motors are build, I would guess the frequency was a more likely culprit.

As none of your converters have a listed output frequency it's hard to say anything sane about that, but I wouldn't have guessed it could be wrong (another testament to my limited knowledge on the subject).

In any circumstance: It's extremely unlikely your razor will blow up.

  • The frequency issue came to mind, but the US uses 60 Hz while in Europe we use 50 Hz, so you would expect the razor to run more slowly rather than (seemingly) go wild. – jcaron Jun 9 '18 at 12:55
  • @jcaron: I considered that the 50/60 Hz difference would give the opposite effect, from what the OP describes, but I simply don't know enough about how those converters work to rule out that some might produce a new frequency. – Henrik - stop hurting Monica Jun 10 '18 at 7:15
  • Alternatively, the Chinese-made converter is simply a fake with no transformer in it, and actually delivers the same 240 volts you put into it. The sellers then hope what people plug into it will be phone/laptop chargers that actually work well on either voltage. – Henning Makholm Jun 10 '18 at 11:01

Most hotel bathrooms in the UK have a dual-voltage shaver socket, with both 230 and 110v outputs - so you shouldn't need to buy anything in order to use it.

  • This is true, but they also all have standard "bathroom" sockets, ie round pin. If you look at the adapters the OP is using, they're all standard US flat-pin, which suggests to me that his power connection is US flat-pin. – MadHatter supports Monica Jun 9 '18 at 10:31
  • See my edits. This is a hair clipper that gets plugged directly into the wall. It uses no battery. I'm also staying at an airbnb, so need a solution for a regular household. – Eric Brotto Jun 9 '18 at 10:36
  • @MadHatter most of the ones I have come across have had both round and flat pin sockets - I've got one in my house that has round pins marked 240v and flat ones marked 115v. Doesn't help Eric if his Airbnb doesn't have one though! – Nick C Jun 9 '18 at 18:32
  • @NickC that's fair enough! Sorry if I muddied the water unhelpfully. – MadHatter supports Monica Jun 9 '18 at 22:30
  • @MadHatter no worries! Shame it doesn't help the OP though, but at least it might help a future visitor... – Nick C Jun 10 '18 at 21:02
