This is definitely not a 12v motor. I bought the 3V version and a 12V version and they are the same. They have very low torque. Running these at 3V for some robot wheels may be fine, but if you actually need to move anything with a little bit of weight good luck. (Couldn't slowly spin a Raz Pi5 and a web cam even at the 16-30 RPM range).
