The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
The California CAT-4620AC runs on corded electric power at 110 volts and holds 4.6 gallons of air, giving it enough reserve for intermittent nailer and stapler work without constant motor cycling. The listed specs show a 20.7 by 18 by 21 inch footprint, which keeps it reasonably compact for its tank size.
At 68 pounds, moving this unit solo is awkward and it is best treated as a stationary or semi-permanent shop compressor. Owners rate it 4.4 stars across 452 reviews, suggesting consistent satisfaction with build quality and output for the tasks they use it on.
At $405, the CAT-4620AC sits at the upper end of the portable corded category. The price is justifiable if you need its tank volume and plan to leave it in place, but buyers who need something lighter or less expensive will find better value elsewhere in the portable segment.
Pros
- 4.6-gallon tank provides enough reserve for sustained nailer and inflation tasks
- Corded 110-volt operation works on standard household outlets
- 4.4-star rating held across 452 owner reviews
- Compact footprint of 20.7 x 18 x 21 inches relative to its 4.6-gallon capacity
Cons
- 68-pound weight makes solo transport impractical
- No PSI, CFM, or motor spec published in the listing
- $405 price is high for a 4.6-gallon portable compressor when alternatives offer similar capacity for less

What buyers say
Based on specs and verified owner reviews, owners generally appreciate the build quality and consistent output for trim nailers and inflation tasks.

The higher price point comes up in feedback, with a portion of owners feeling the value is strong only if you use the full tank capacity regularly.
