Exactly as stated in the title. All my life I’ve been able to touch my phone or computer’s electrical charger output (accidentally or for whatever the reason) with no sort of “buzz” or feeling from the electricity going through the output. At least that has always been my experience with it.
Just in case: Don’t intentionally try this of course.

Unfortunately there are a several incorrect answers here.
What makes mains electricity dangerous is the voltage. Electricity is a bit like water, and voltage is the water pressure. While technically it’s the current (quantity of water) that is dangerous to your heart, if the voltage (water pressure) is too low, the dangerous levels of current simply can’t be pushed through your body. So high voltage is like a pressure washer to your skin, and low voltage is like a bucket of water over your head. (Bad analogy, but consider just your skin – the bucket of water would wet your skin but it wouldn’t go through the skin into your blood like a pressure washer)
The chargers and usb connectors have a low voltage (pressure), and even though some can supply a very high current (amount of water) to your equipment, the pressure is not enough to get through your body and harm you. If you were mostly made of metal, (water analogy, you were made of sponge) it could harm you a lot more.
This is a great simplification, but it should answer your question.
