More shocking Chinese toys (electric shock pranks)

In this video I test another 3 electric shock prank gadgets from China. An electric shock hand grip, an electric hand buzzer and an electric shock pen. I make a teardown of them and reverse engineer the schematic. I also measure the output current and the peak voltage. WARNING: These devices may be dangerous.
