Really dodgy pink USB charger.04:33

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. 😛
