Everyone has an opinion so I'm not going to be shy about giving mine. I have traveled with a 12v tire kit for many years and it has pulled my fat from the fire a number of times. Personally, I use the Slime kit with a jug of tire repair goo and a 12v compressor. I augment the kit with a plug kit purchased separately.
As far as time, the 12v compressor will get you to 80psi but it will take a while; usually a lot less time than waiting for AAA to show up and besides, I'm in no hurry, I've got a flat . . .
