The cheap shitty pink USB charger from China song.

This is a song about cheap shitty pink USB chargers and how they can blow your prized technical possessions up and potentially blow YOU up in the process.
Of course, they don't HAVE to be pink, but it's all the more humiliating if they are.
The simple fact is that many of the cheap USB chargers sold on ebay and directly from China are designed with no regard to proper electrical isolation between the mains side and the low voltage USB output. This can result in equipment damage and electrocution.
I strongly recommend that you only use good quality chargers from known good sources for your equipment. And despite not being an Apple fan-boi I regard their iPad charger as one of the most trustworthy travel chargers you could carry with you.
Please note that I didn't actually blow my iPad up with a cheap shitty pink USB charger from China. I'm not dumb enough to plug anything precious into one of these things.

Really dodgy pink USB charger.

I was originally going to do a teardown on this, but the cramped circuitry and breathtakingly negligible safety tolerances ruled it out as a viable device from the start. I don't think that having a PCB gap of 0.25mm or 0.01" is really safe at all. Particularly when the gap between the two pads involved had a little line of flux impregnated with solder globs.
Such a small clearance between the mains circuitry and the USB connector itself is just appalling. It really poses a shock risk for anyone touching a device with exposed "grounded" metal plugged into a charger like this. The iPhone immediately comes to mind due to it's external metal antenna trim. Perhaps this explains the unfortunate demise of the Japanese air hostess who was electrocuted when she answered her phone.
It's so bad that I wrote a song about it. :P

Pink USB panda versus 240V.

This USB "cup heater" just wasn't getting hot enough. So I upgraded it to over 3kW (briefly) by making a 240V mains to USB adaptor.
