VIAIR 300P Air Compressor

One of the worst things that can happen when you or a family member are out driving is to have a tire go flat. The VIAIR 300P will help you with that. Yes, it’s possible to replace your flat tire with a spare, but sometimes those deflated tires simply need a bit of air to get you and your loved ones back on the road.


VIAIR 300P Portable Compressor is the kind of portable air compressor that every person can appreciate having in the trunk. No, it’s not a high-end air compressor for working with expensive pneumatic tools. But what the VIAIR 300P Portable Compressor does – provide quick, high levels of compressed air for filling up tires or other inflatables – it does well.

Easy to Use on the Road

Viair 300p reviewIf you’ve stopped by the local gas station in recent years, just to top off the tires with air, you’ve probably noticed that some stations are charging a dollar, just to get a bit of air. Paying for compressed air is bad enough, but when you are nowhere near a gas station and in need of air, you need another alternative.


Those are the times when the VIAIR 300P Portable Compressor comes in handy. And since the VIAIR 300P Portable Compressor easily hooks up to standard car batteries as a power source, there’s no problem getting tires inflated, as long as you can get access to the car’s battery.


They are also remarkably long-lasting and have a strong capacity. This compression system consists of a range of cool accessories which covers the five in one inflator; an open ended hose is comprising of about 100PSI gauges, heavy duty batteries and much more. They also have a 33 % duty cycle and about 150 maximum PSI.

If you’ve ever purchased those little, less than sturdy tire inflation compressors, you know that most of them take forever to fill up a standard car tire, and most of them simply don’t last past a few uses. The VIAIR 300P Portable Compressor, on the other hand, offers plenty of quick air and is built to be used for many years to come.

  • The hose is sufficiently long to reach about all four tires.

VIAIR 300P Cons
