In this video I'm testing a dangerous Wireless Charger (Qi Charger) from China. The efficiency is about 45% in the very best conditions. The transmitter has a poorly aligned connector which you have to fix yourself before you can use it. But the best is coming. The receiver has an overheating component, probably a resistor. It gets steaming hot and melts through the cover. You are supposed to put the receiver inside your smartphone, so it is squeezed against the battery. Yes, a red hot resistor is pressing directly onto the flammable Li-Ion battery! This amazing device is going to set your mobile phone on fire or make it explode.
