I got the following in my email. Do you think it is possible? It may be likely as cell phone chargers are SMPS operating at high frequency. When a call comes in, again some high frequency is generated in the mobile phone. Even if the SMPS is an isolated DC charger - will it result in mains voltage getting leaked to output (poor quality SMPS designs?)
A person was recharging his mobile phone at home.
Just at that time a call came in and he answered it with the charging Instrument still connected to the outlet.
After a few seconds electricity flowed into the cell phone unrestrained and the young man
was thrown to the floor with a heavy thud. As you can see, the phone actually exploded.
He was rushed to the Emergency Room unconscious and with a weak heartbeat and burnt fingers.
Unfortunately he was pronounced dead on arrival.
Cell phones are a very useful modern invention.
However, we must be aware that it can also be an instrument of death.
NEVER use the cell phone while it is hooked to the electrical outlet!
If you are charging the cell phone and a call comes in, unplug it from the charger and outlet
