Overview
The DEWALT D55146 is a corded electric air compressor running on 120 volts, with a 4.5 gallon tank and an 88 pound body sized at 28 by 24 by 16 inches. It plugs into standard household power rather than running cordless.
A 4.5 gallon tank sits in the portable-to-mid-size range, enough for intermittent trim, framing, or inflation tasks without the recovery time of a larger stationary unit, though it will cycle more often than a bigger tank under continuous use. At 88 pounds it is not a one-hand carry, so plan for a cart or a two-person lift when moving it around a site.

- 28 x 24 x 16 inch dimensions
Who it's for
Works for contractors and DIYers running pneumatic tools on 120 volt power at a fixed or semi-portable location. Not ideal for anyone needing a lightweight, grab-and-go compressor or true cordless operation.
Pros and cons
- 4.5 gallon tank for sustained intermittent use
- Runs on standard 120 volt power
- 88 pounds, not easily hand-carried
- Corded electric only, needs an outlet nearby
Performance notes
The 4.5 gallon tank on 120 volt power balances air reserve against recovery time, giving enough capacity for stop-start nailing or fastening before the motor needs to refill the tank. The 88 pound weight and 28 by 24 by 16 inch footprint make it better suited to being wheeled or lifted into place than carried by hand.
