That is nothing. Google image iphone charger fire.
I have seen some blown iPhones to pieces due to the charge.
It's not just iPhone any charger device is suspectable to catching fire, there have been a number of fatal house fires due to phones been left on charge and catching fire over night, there was 3 kiddies killed in one near me not too long ago.
That looks like a legit Apple cable, an impressive cheapo!
The legit Apple ones cost a fortune, but we stump up for them with the school equipment - can't afford not to really.
Even the apple ones get mullered tho
I was told that the fire brigade warn that many house fires are started by cheap imported Chinese laptop batteries...

I would not bother with a cheap charging cable ever, especially after all the programs about people getting electrocuted or phones blowing up on them or catching fire, its too great a risk for saving a few quid on the device, with these devices being already prone to overheating that is (I had an ipod photo years back that was like a hot brick when using it until it blew and Apple changed it for a brand new one), now I am finding the same issue with my iPhone though on the standard cable any hard long use of the phone and it starts going red hot, so I think its on its last legs now.
Current battery technology is scarily unstable.

What makes Apple's iPhone charger special
Apple's power adapter is clearly a high-quality power supply designed to produce carefully filtered power. Apple has obviously gone to extra effort to reduce EMI interference, probably to keep the charger from interfering with the touchscreen. When I opened the charger up, I expected to find a standard design, but I've compared the charger to the Samsung charger and several other high-quality industry designs and Apple goes beyond these designs in several ways.
The input AC is filtered through a tiny ferrite ring on the plastic case (see photo below). The diode bridge output is filtered by two large capacitors and an inductor. Two other R-C snubbers filter the diode bridge, which I've only seen elsewhere in audio power supplies to prevent 60Hz hum; perhaps this enhances the iTunes listening experience. Other chargers I disassembled don't use a ferrite ring and usually only a single filter capacitor. The primary circuit board has a grounded metal shield over the high-frequency components (see photo), which I haven't seen elsewhere. The transformer includes a shield winding to absorb EMI. The output circuit uses three capacitors including two relatively expensive tantalum ones and an inductor for filtering, when many supplies just use one capacitor. The Y capacitor is usually omitted from other designs. The resonant clamp circuit is highly innovative.
Apple's design provides extra safety in a few ways that were discussed earlier: the super-strong AC prongs, and the complex over-temperature / over-voltage shutdown circuit. Apple's isolation distance between primary and secondary appears to go beyond the regulations.

After reading this thread I'm terrified that one of our charging docks will catch fire - if the phone has been disconnected is it still drawing enough current to combust?
That's a good question. I always turn everything off at the plug though. Not because I'm worried about fire but because I'm worried it is actually using my precious electricity.
