Although this incident happened a little while back, it made this evening's TV news in Sydney. There was a warning that the same dangerous chargers are readily available on the Internet too.

I imagine that there are similar unsafe versions that sold for around $6 here, also available for the larger U.S.A. market.




How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area. All that Identical Checksums gives is the possibility of REGENERATING the file to close to that of the original file.

I once had a serious issue with the original USB charger provided by Apple with my iPad. It generated a big spark when I plugged it; the charger half burned; and it killed the power line to the wall socket. I was very pleased that I got away with it without any injuries.

Even Apple have problems sometimes ... recent EU adaptors were subject to a recall.





...in my opinion / experience...

While I agree "Everything may matter" working out what actually affects the sound is a trickier thing.

And I agree "Trust your ears" but equally don't allow them to fool you - trust them with a bit of skepticism.

keep your mind open... But mind your brain doesn't fall out.

Third party chargers can also damage your iPhone 5, burning out the U2 IC chip:

Electrocutions have occurred in the past, such as the one in 2013 in China:

This resulted in a "Takeback Program" by Apple:

Nobody actually expects they will be the one to get electrocuted or have the iPhone destroyed by a faulty charger. In fact, "giveaway" chargers are becoming common at conferences, etc because they are popular swag.


Here is one I received while at a work training recently that looks "identical" to a genuine Apple charger...but it isn't:

Why wouldn't anyone use it? Yet it may damage their phone or electrocute them according to Apple. I am tempted to drop it in my suitcase as a backup when I travel...sometimes it is nice to have an extra USB charger, yet I know I shouldn't....

I recently purchased a Bolse USB charger and only read the news about people being hurt by them recently. Each port has "Over-voltage, over-current, and short-circuit protection", and this guy had a review that said it was reliable



Still, the recent news does make me a little uneasy about usb's for sure.
