I've been dismayed that the non-bike 12g carts don't get my 700x25c tire to 110-120psi.
But I never considered that two 12g non-bike carts still cost less than one 16g bike marketed one.
I think having two (actually would carry four) 12g is better as I find I am giving them away faster than I use them.
Another benefit is one can use one 12g and know if tire if fixed, if not one can still use the 2nd one and have enough pressure to finish a ride.
