This is the typical non-isolated AC/DC converter that by its nature, can pose a severe shock hazard. The largest parts are the 10K ohm, 5 watt resister and the .22 mF 250 V capacitor.
The image of the 10K ohm resister is greatly enlarged.
Also, if the phone were charging, just touching it would give you a shock. It may not kill you, but customers would notice.
No cell chargers are made that way.
