Why Does My Phone Charger Spark When Plugged Into Power Strip?

Hello, as in the subject - I have noticed that when I plug the phone charger into the power strip (of course the charger has a plug without a protective pin) when I plug it in there is a slight but visible spark jump from the hole into which the phase is led. What is causing this?
I should add that there is no spark at all when plugging in a modem, router or landline phone to this strip, but this is not the fault of this particular charger, as I checked another one from a different phone - the spark jump is visible again.

There is no softstart function on the charger and the capacitor in the inverter wants to charge. This is typical. This jump should not be there if you unplug the charger for a second and then immediately plug it back in.

This is probably due to the high input capacitance of the charger.
When switched on for a very short time, until a steady state is reached, it is almost a short circuit.

I see, in that case it is not a fault of either the skirting board or the home installation? As I wrote - other appliances when connected do not give a spark jump, only those phone chargers.

Since, as my colleague wrote, this spark is "almost a short circuit", is it dangerous for the skirting board or the appliances running on it, or the installation? I wouldn't want a situation where when I plug in a charger it knocks out my fuses....

This phenomenon is perfectly normal and nothing will happen.

However, laptop power supplies can sometimes blow a fuse in the power strip.
Again, this is nothing unusual or dangerous.

Hmm, what puzzles me, though, is that when connecting the aforementioned chargers at my girlfriend's house to a regular extension lead without pins, no spark jumps.

It's worth mentioning that she has a newer, 3-wire installation with sockets in the walls having protective contacts, while at my place there is an old 2-wire aluminium installation with bridging done (done only a week ago, so there's no way for 99% that the cables are untightened), while from this socket there goes the strip to which I connect the chargers and sparks do appear.
However, other sockets in other rooms (non-zeroed) also show sparking, so I don't understand it myself anymore....

EDIT: I checked a few more times at the other house, my mistake - however, at the girlfriend's house also the same jumping occurs in the sockets when plugging in the chargers simply at my place it happened to me recently almost every time I plugged in, here as if less frequently.
