How to convert 110V to 220V

Use a 110 / 220 transformer

How to transform 110 V to 220 V transformer into 220 V to 110 V transformer
My friend brought back a razor from Japan. The input voltage was 110V, so I bought a transformer online. I didn't think about it. I read the wrong title and bought a 110V to 220V transformer by mistake. Is it difficult to change it into a 220V to 110V transformer?

It depends on what kind of transformer you are. If it's an inductive coil, just switch the two ends of the input wiring and the two ends of the output wiring. If there's no electronic protection, the bare transformer will do. If it's an electronic transformer, it can't change

110V on the switching power supply,

It is the input power supply voltage of electrical appliances. Two kinds of switchable. Domestic single-phase commercial power is AC 220 V / 50 Hz
