I have a sears 110v that travels with me. I also have the g614 and have no problem with this compressor. The compressor is not the pancake style is rated for 125 psi. I will have to say to get to 110psi you have to keep the compressor running.
It kind of depends on what YOU think a reasonable amount of time is for the job and how much air you're talking about. If you're inflating from flat then most of the small ones will take a lot of time to bring a tire to over 100 LB of pressure. If you're talking about adding 10 lb. of air then lots of small 12 volt pumps will do that job in three or four minutes time.
I carry a small "Slime" Chinese made 12 volt pump. It comes with case, 20 feet of 12 volt cord and 20 feet of air hose and has a max pressure of 150 PSI. It will add 20 PSI of air in my 245/75/17 E truck tires in about five minutes. Came from Walmart for about $35.00 or $40.00.
Good luck / Skip
I like the ones that you can set to turn off when they reach the pressure you set. They are slow so you can be doing something else while it is pumping and you don't have to stand and watch it, for fear of over filling a tire.
Q Industries sells their MV90 that does 110psi just fine. I have one for my G614's....no problem. I believe it's the best bang for the buck in 12v compressors around. It's very competitive with more expensive Viair units. BTW, If you know the axle weights of your unti and look at the manufacturer's load tables for the G614, you might find that you are good at 90 or 100psi. I am running 95psi in mine now.
