your raspi runs on 5w power maxing out at 6w
a laptop starts at 20w and can consume 200w depending on the processor and graphics card
the raspi is a good minicomputer. do not buy it for a stupid price.
i got the pi for 5 bucks and the pi4 for 30 bucks.
very happy with both.
you can learn so many things with the raspi it is mindblowing.
learning is not for everyone
