Thank you so much! I am very glad that people like my projects. I will try to do interesting projects further.
the page doesn't say anything about the duty factor for higher outtakes.
Its non-cheap price tag and "Makermotor" brand sounds to me like it's intended for the Arduino lot/ Robot making crowd.
A (no-load) 50 rpm motor with 4,4 ft-lb starting torque will eventually get the jack up,
but it'll take some time and probably complain a bit when the fully loaded scissor is at its bottom,
where the screw, nut and its bearings is at its highest stress and the jack has its max lift/ turn.
For the cost of this Makermotor alone you could get a 2 times as powerful, complete electric scissor jack at a FleaBay discount,
but then you wouldn't have a DIY project...
Added: Most 2,5 ton electric jacks available of FleaBay etc has a 100-120W motor and a 15 A fuse -
giving a max momentary input power of 200 W.
I've found none of these listing the full height & load lifting time (nor the motor's rpm),
but a few reviews state "within a few minutes"...
If you choose a low watt & lo rev DIY solution - there's simply a time penalty to pay for any given load,
(if it'll work at all) as there's simply no free lunches here either.
YMMV - Personally I'd rather visit the local scrap yard for a heavy duty hi-tork piece with 200-300-ish rpm for a mere 10 bucks.

I just wanted the motor to work 12 Volts, and not from 24 volts, since the car has only such a voltage.
it has a power of 100 watts, but it is also 24 volts.
According to your advice, tomorrow I’ll go to the warehouse of old cars, try to find a motor there.
