Handheld inflator?

[question everything]

My 2014 KIA Soul came without a spare tire. Standard or the toy one.

I drive it mostly around town but several years ago we did take it out of town - 400 miles each way. And, frankly, did not even consider this. KIA supposedly provides a 24 hr road service, or something, the number is on the window.

But a recent MotorMouth column suggested that an inflator that can be plugged into the old cigarette lighter, as well as a can of puncture sealer should be in many cars. This duo, he said, replaces the spare tire which took up space and added weight.

Any opinions here?

Thanks.

I am not a car head. For me it is a convenience to take me from point A to B in a reliable and safe way.
