Since pins on both sides are in reach, can be touched and usually are connected to a wallcharger with enough AMP to kill a human.
Would it be safe to touch both sides with one hand? With wet fingers?
Does the charger somehow communicate with the device before sending current?
Edit: I am in Europe so having 230V50hz, Charger is the classic 12W 2.4Amp USBA one.

Honestly, with a dry body, you probably wouldn’t even feel anything below 30 volts or so. USB (which is what is carried on that cable) defaults to 5 volts. Your body is far too resistive of electricity for that to do anything you’d notice.
I have an iPad whose charger only does 5.1 volts, so it’s not going any higher. If yours is 2.4 amps at 12 watts, 12/2.4 = 5 volts as well.
You can’t force low voltages to go through things if the resistance is too high, and human skin has pretty high resistance. A car battery can output 400+ amps but at only 12 volts, it’s completely safe to touch both terminals of the battery as long as you’re dry. The battery *can’t* push all those amps because your body isn’t taking it, any more than it can push them through the open air if nothing were connected to them.
