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?
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.
