Electric shock from laptop charger

Can a laptop charger give an electric shock? I accidentally got the plug on my arm and I felt a little shock feeling. The charger is 19V at 2.1 amps. Last time though, I have touched it with my hands and I didn't feel any shock.

Sometimes the following can happen. You are charged up with static electricity and you get a shock touching a device that may or may not be grounded / earthed. Or when you unplug an electronic device there can be a small shock voltage from the collapse of the magnetic field called a BACK EMF

Laptop charger
I have a laptop in which the charger 'pin' (to plug into laptop) seems bad. It's a bit loose when I wiggle it and when in the laptop, the cord has to be positioned just right for it to charge (it seems to lean the pin to where it can charge). I'm not sure if it's the charger or the port. The...

Can HP charger be used for Gateway laptop?
