Smittybilt 2781 Review – Take A Closer Look At The 5.65 CFM Universal Air Compressor

Smittybilt 2781

If you have a need for a powerful compression unit for automotive applications then the Smittybilt 2781 may be for you. Priced around $150, it is nearly three times the price of many 12 Volt compressors out there. However, If you need a powerful tire pressure when off-roading, then based on the customer feedback the Smittybilt 2781 is worth taking a closer look.

Powered by a 1/3 horsepower oil-less direct drive motor, it has been advertised to be the most powerful air compressor in its class. The maximum airflow is 5.65 CFM/ 160 L/min which is pretty impressive. Most other compressors you will find do not even flow 5 CFM at 0 PSI.Its little brother, the 2780 model offers 2.54 CFM/ 72 L/min.

The Smittybilt 2781 universal air compressor only has a 40 min runtime at 40 PSI before it needs a break while there are continuous duty cycle compressors on the market such as the Viair 450C. However, it is still much better than the MasterFlow MF-1050, the favorite of many 4-wheelers , that offers a run time of 20 minutes.

The operating temperature of this unit is – 4 to 140 deg F. There is an automatic protection device to to prevent damage to the compressor in the event it reaches an unsafe operating temperature. A protection circuit immediately disconnect the unit from the power source and will automatically reset itself when the temperature returns to a safe operating level.

There is an integrated 150 PSI easy to read pressure gauge on this tire inflator. The Smittybilt 2781 is also equipped with a quick release 24-foot coil hose, longer than the one provided by the 2780 model (16-foot). Other features included are an easy twist screw-on brass inflator top, built-on cleanable airfilter, and anti-vibration rubber feet. A storage bag is also included in the box.

With a weight of 15 pounds and dimensions of 15 x 11 x 12 inches, the Smittybilt 2781 is a good choice for anyone looking for a small portable air compressor that can be moved between vehicles while on work road trips. The 5.65 CFM universal air compressor has received some very positive feedback from its customers at and currently has a review rating of 4.3/5 stars.

A few complaints have been made about the pressure gauge. Reportedly, it gives unclear reading when running. You need to stop the unit in order to read the accurate pressure. Others have found that it gets hot fast. One reviewer commented the 40 min cycle time is way too long for the pump. However it depends on the outside temperature.

Despite some negative comments, customer feedback suggests that it does work well for inflating tires and other inflatable items quickly. According to one reviewer, it worked well airing up a 35″ tire from 12psi to 32psi in about a minute. When it comes to construction, some have commented that it is a solidly built compressor.

For people on a tight budget, the Q Industries MV50 might be the way to go. For higher quality, Viair has some very good options. That said, if what you need is a relatively inexpensive, well-built tire inflator that offers fast air delivery, then based on the customer reviews the Smittybilt 2781 deserves serious consideration.
