When we told you last month that fake iPhone chargers were cheap, dangerous and could be purchased anywhere, we meant that using one could threaten your physical safety.

Now it turns out using the wrong charger can do other types of damage too.

When Miss Li connected her iPhone 5 to the charger in Jingtai Tower in Guangzhou’s Tianhe District shortly after 10 a.m. Thursday she was in for a shock. As soon as the two devices connected, there was a small explosion that sent sparks flying and left burns on her fingertips, Yangcheng Evening News reports.

Her mood was not improved when it turned out that this explosion caused her whole company’s power supply to blackout.

Although Miss Li claims to have bought both the phone and the charger from an accredited store, her mistake may have been to use the same charger that she used for her old iPhone 4. She called the Apple customer service hotline and gave the serial number of the phone but is yet to receive an explanation as to what happened.

The city’s Industrial and Commercial Bureau suggested Li may be entitled to receive compensation.

Li is considerably luckier than Southern Airlines stewardess Ma Ailun who was killed last month after being electrocuted while using her iPhone while it was still on the charger. It is thought that she had just got out of the shower.
