This was posted a couple of days ago on FT's site by Geek in response to a customer who had his Ego charger explode - model HBT-061. I'm not saying this is FT's issue since we're talking about a generic ego charger that can be bought in many different places. Other people in that thread mention that it's the reason why they only use branded chargers. My question is, what is a BRANDED ego charger? can someone point me in the right direction pls?
"...
Since late 2012 we have been testing all wall chargers for their output voltage and current. Since then I've personally seen at least 3 chargers exploding in the QC area. That's what I've seen as I walk pass the QC area -- we don't seem to have a log of total explosions we had during QC.
Upon examination, we find that most chargers explode because their capacitors were soldered the wrong way (i.e. reversed polarity). When they get charged with reversed polarity, they explode. They usually do this within seconds being plugged in though and as such we are able to eliminate them during our QC. As you mentioned that it worked for 10 minutes, yours may not be caused by this reason.
I do personally avoid crappy China wall chargers since then -- even if the number is 3 out of 10000. I just don't want to risk my house for $3."
