Overview
A 12-volt DC air compressor from VIAIR, model 45157, powered through an SAE connector rather than a cigarette-lighter plug, weighing about 13 pounds.
An SAE connector usually points to a compressor wired into a vehicle's electrical system for a semi-permanent mount, unlike lighter-plug units meant to be tossed in a glovebox. VIAIR is an established name in vehicle air compressors, though this listing does not publish CFM or PSI output figures. At 13 pounds it is heavier than a typical portable inflator, consistent with a fixed-mount design.
- Power source: 12V DC SAE
- Voltage: 12 volts DC
- Item weight: 13 pounds
- Brand: VIAIR
Who it's for
Fits vehicle owners who want a wired-in 12-volt air source for tires or an air-ride setup. Not the right pick for someone wanting a plug-and-go unit with a lighter plug, since this uses an SAE connection.
Pros and cons
- SAE connector suits a wired-in vehicle setup
- VIAIR is an established compressor brand
- No CFM or PSI output listed
- Heavier than typical portable inflators at 13 pounds
Performance notes
Power comes through a 12-volt DC SAE connection rather than a lighter plug, and at 13 pounds the unit runs heavier than typical portable inflators, in line with a compressor meant for a fixed mount rather than a glovebox kit.
