2.5 CFM at 90# seems to me more like a shop compressor
Than a portable unit, that is the size to carry in an RV

Going to need about 2hp to produce that flow rate at 90#

Please post any links to this compressor

I carry a Crafstman 6 gallon pancake 120 VAC compressor that says it goes to 150 PSI.. and it does That's good for tires up to around 120 (not much higher) I have a small portable that says it goes to 300 but I don't believe it and I should live that long to blow up a 22.5" to 110 PSI

As well as a good compressor you want a large storage tank! I installed air horns and it came with a 2 gallon tank and decent size 12V compressor, I don't know the CFM off hand, but it is 150 psi. I also installed a 2 1/2 gallon 110V 125psi compressor. I tied them together so I have 4 1/2 gallons of air on hand. I run my air hose for inflating things off the 110V compressor which is tied into the ore compressor. I can run either one or both at the same time.

Maybe an air horn kit is something to look into. They can be had with high quality compressors and up to a 5 gallon tank.

That you, always nice to learn something helpful

I've been using a 12v master flow tsunami 1050 for almost 10 yrs and three RV's, it did well with my gasser for topping up, but was not the right tool for the 22.5 tires on the DP
Some day I will replace it with a 120v portable

Even my Black & Decker does far more than that. 165PSI if memory serves.

It also does high volume/low pressure for inflatable toys.

I'm concerned about that Kobalt - we already have enough scams. [emoticon] From the description;

class leading 2.8 scam at 90psi

As far as the $40.00 one from Harbor Freight, I bought one of those for my Mom, if you have all day it might be OK but its pretty darn slow even for a car tire.


There are 24 hours in every day - it all depends on how you choose to use them.

Have had the 400prv for almost ten years. Still works great. Tops off 22.5" MH tires quickly. Light weight and easy to store. Can be kept in the trunk of you car

Our 400P-RV Automatic powerful portable tire inflator kit will inflate 275/80/22.5 tires from 80 to 90 psi in just 30 seconds. While the unit is intended for RV use, it can be used for virtually any tire since it comes with accessories for more varied inflating situations than any other portable compressor kit on the market today.

Portable compressors with automatic shutoff come into play when moving from tire to tire, and when checking tire pressure in the middle of a tire fill. A typical portable compressor must be turned off between tire fills, and anytime you want to check tire pressure. If you aren’t near the compressor, this can turn into running laps back and forth to the portable compressor to turn the unit on and off. Automatic portables do not work in this fashion and will save you time & effort to get tires inflated quickly.

Please Note: The air hose supplied with this kit may become brittle from prolonged exposure to UV/sunlight. – Stow when not in use. Never allow the hose to come into contact with the head of the compressor during use (melting hazard). The use of the included air hose is not recommended in sub zero or freezing conditions. The 400P-RV does not work with Presta bicycle valves, unless used with a Presta Valve Adapter.

I have been carrying one for years in my coach and it does find for my 22.5 tires and my air tools, etc. Never had a problem with it and am currently using it to operate my nail gun shooting 3" nails without any problems. Without a good CFM plan to spend all day to air up large tires...volume is what is needed not just PSI.
