What handsfree breast pump are people using?

I have a son who is 12 months, with him I used the Medela pump in style, it was a good pump and I had great results with it.... but I was also stuck to an outlet when I needed to pump.

We are going to be trying for #2 sooner than later and im trying to do more research on other pump options that would allow me to pump while chasing a toddler.

I can still use the pump in style early mornings or late at night when my son is sleeping, I’m just looking for the best option for during the day.
