Dangerous USB phone chargers 15

A pair of small 5V 1A USB chargers, what's inside, checking the safety, interference and quality. The first one was a part of handheld oscilloscope accessories, the second one is from eBay. Let's see what surprises are hidden inside of them. Some chargers may not comply with safety regulations, cause an electric shock or fire. Their current rating may be fake, the output voltage may be wrong and they can cause electromagnetic interference (EMI) or damage your USB devices.
