sandyk Posted June 27, 2014 Author Share Posted June 27, 2014 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.

Boris75 Posted June 27, 2014 Share Posted June 27, 2014 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. Link to comment
Audio_ELF Posted June 27, 2014 Share Posted June 27, 2014 Even Apple have problems sometimes ... recent EU adaptors were subject to a recall. Eloise Eloise --- ...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. Link to comment
InfernoSTi Posted June 27, 2014 Share Posted June 27, 2014 Third party chargers can also damage your iPhone 5, burning out the U2 IC chip: Unauthorized Third-Party Chargers May Damage iPhone 5 Charging Circuitry - Mac Rumors Electrocutions have occurred in the past, such as the one in 2013 in China: Apple Pledges Investigation After Chinese Woman Reportedly Electrocuted Using a Charging iPhone 5 - Mac Rumors This resulted in a "Takeback Program" by Apple: Apple Launches Third-Party USB Charger 'Takeback Program' - Mac Rumors 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....

new_media Posted June 27, 2014 Share Posted June 27, 2014 Wow. I think this is one instance where we can all agree that a USB cable made a difference in sound. Link to comment
mousespecial14 Posted July 8, 2014 Share Posted July 8, 2014 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. Link to comment
