VIAIR 400P Portable Compressor

Portable Compression Stowed for the Road
The VIAIR 400P Portable Compressor offers inflation of up to 35-inch tires at a rapid rate, and operation at up to 150 PSI for up to 15 continuous minutes at a time, providing that there are 30 minutes provided afterwards for the unit to cool sufficiently. The unit is powered by an easy to establish temporary connection to a 12-volt battery power source via included alligator clamps. The 400P comes with an open-ended tire inflation hose with included 100 PSI air pressure gauge that offers the following functions: air up, air up intermittently, air down, air down intermittently and check tire pressure. To check tire pressure, simply turn off the portable compressor to halt inflation and check the pressure on the air pressure gauge. Additional parts provided include an inline fuse holder, a 8′ power cable, a heavy duty sand tray with vibration isolators and deluxe carry bag.400P Air Compressor Specifications

About Compressor Duty Cycle
Compressor duty cycle refers to amount of time a compressor can be operated in a given time period, at 100 PSI and at a standard ambient temperature of 72°F. Duty Cycle is commonly expressed in percentile as: compressor on time (compressor on time + off time) %. As an example, a compressor that is rated for 25% duty cycle means that compressor can be operated at: 100 PSI @ 72°F for 10 minutes on and 30 minutes off. 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle.Fill Rates:

About VIAIR Corporation
VIAIR offers the most complete line of air compressors and air accessories for both the on-and off-road markets available anywhere. VIAIR products are used in the OEM segment, 4×4 and Sport Air Suspension and have become the industry standard for both 12- and 24-volt automotive applications worldwide. Their compressors are currently being used in every corner of the globe, in the harshest climates imaginable and the company is recognized by its customers and peers alike as the leading manufacturer of high performance air compressors for mobile pneumatic applications.

I was impressed with the design and materials used in this compressor. The hose is heavier than I expected and the brass screw on fitting provides a positive seal with the valve stem, prevents leakage and eliminates the need to hold the chuck on the valve stem. The alligator clips are well constructed and provided a solid electrical connection. The electrical leads are long enough to reach from the battery on my passenger side to the compressor sitting on the floor next to the driver’s side tire.

I was so impressed with the first test that I repeated the whole process again, The second run took 1 minute and 29 seconds. The noise level was lower than I expected and there was very little vibration from the compressor. The only negative I noticed was that the work / power indicator light is on the back of the unit and the built in gauge is on the top. I haven’t used this at night, but I think it would be difficult to read the gauge without a flashlight.

Other reviewers mentioned to hold on to the factory shipping box for storage since the compressor doesn’t come with a carry case. I looked around the shop and found a small heavy plastic “dry box” for transporting and storing ammunition. I put a bundle of shop rags in the bottom to cushion the compressor and the coiled hose and electrical cord slid right in along side the compressor. I placed another bundle of shop rags on top of the compressor. The top of the “dry box” has storage compartments so I put in a complete tire plug kit, some spare plugs, two spare valve stems, a couple tire pressure gauges, a small Mag Lite flashlight a a couple spare AA batteries for the light. This whole kit only weighs about 4 pounds and takes up very little room in the storage area behind my rear seat.

Now I’m waiting for my next off road trip where I drop all 4 tires down to 15 psi. I want to see how long it takes to re-inflate all 4 tires back to 35 psi and if I can air up all 4 tires without overheating the compressor or exceeding the 45% duty cycle. I think unhooking the compressor, checking the pressure and moving the unit to the next tire will probably be enough time to allow the unit to cool before the next inflation.

Don’t let the small size or the amazingly low cost of this unit keep you from considering it.

EPAuto 12V DC  Air Compressor Pump, Digital Tire Inflator

My family has always kept air pumps in case of emergency. My last one I got on discount at a store and it was terrible. This pump is great! I bought it for my boat trailer. It pumped up the tires, with my heavy boat on the trailer, and worked great! I love that you can set it to the correct PSI and then just walk away. Great buy!

If you are  big fan of avoiding gas stations for keeping my tires inflated. Beyond the awkwardness of the pumps, their effectiveness is sometimes sketchy. Now, with today’s tire pressure monitoring systems (TPMS), you get the reminder if you’ve gone too long without checking and what more perfect and convenient time to refill tires than on a rested and cool car outside your own front door.(we have written a guide about Impact Wrench and chainsaw)

This does everything you would ask of a portable inflator: it’s fast, it’s efficient and it’s quiet. My old inflator sounded as if I was tearing up my driveway when I used it and it probably took twice as long to work.I saw some questions about the potential lost air while detaching the connecting hose and it seems like the pump may run a little over the stated PSI as protection for that situation. The automatic shut-off when it reaches the pressure you set is a huge boon, as I can rumble around in the trunk or work inside the car without having to constantly monitor the pump.I can’t say much about the carrying bag, it’s a silly little thing that’s likely to tear over time, but that’s meaningless when talking about performance and value. If I had any quibble at all, it would be that I don’t seem to be able to shut off the light on the pump. It’s not a big deal from a power perspective, just an OCD thing.This is a great purchase


This is the best air pump I’ve ever owned!

  • Turn unit on to inflate, off to check pressure pressure using onboard gauge

AIR COMPRESSOR KIT with Advanced Inflator Pump

  • NO MORE WAITING 6 OR 8 MINUTES to inflate your flat tire. A standard 16” tire takes about 3 minutes to inflate to 30 PSI. To inflate a low tire it only takes about 2 minutes to inflate from 25 to 35 PSI (we recommend keeping your engine running during use). This small, compact and yet powerful portable tire inflator has a max pressure of 100 PSI, a max power of 156 Watts, and a cord reach of over 12’ for easy access to all tires!
