Hands free breast pump

Ch

First baby and I am planning on nursing and pumping. Any recommendations for a good wireless, hands free pump? I’m up and on the go and in my car a lot for work each day. I also have a dog with extreme epilepsy and I have this fear that he’ll have a seizure or something will go wrong while I’m chained to a plug in the wall. My SIL had one years ago and I remember her running around and being fairly mobile with it but she can’t remember the brand!
