Do mobile chargers have a transformer in them? Answer Wiki. Mobile chargers have transformer in it. However it is not conventional laminated core transformer operating at 50 Hz, but a ferrite core transformer operating at hundreds of kHz or even few Mhz. High operating frequency results in very small size of transformer, giving impression that there is no transformer in the chargers.

How many turns in the secondary of a transformer? Using transformer equation, and considering 100 turns in the primary (just an assumption), and a 220V power supply, I calculated that there should be about 8 turns in the secondary. Using the same equation for a mobile phone charger (5V) and considering 100 turns in the primary, there should be about 3 turns in the secondary.
