Assess part 45244 as a direct-battery Digital compressor for a vehicle-tire scenario requiring press-on Schrader and user-selected stopping. It has a 23A maximum draw, a 76.4A inrush figure at 0 PSI and a separate 40A fuse. The product page and manual disagree about hose length, so numeric reach is not settled here.

Assessment scenario: Preset-stop direct-clamp car-tire setup with a press-on Schrader chuck
A source-based assessment scenario that combines a 12V direct-battery connection, documented passenger-car use, an included Schrader/press-on path and user-selected target stopping. It does not mean these are the visitor’s actual requirements or certify a specific tire, vehicle circuit or offer.
Explore this buying guide ↗Why consider this model?
- The exact VIAIR page and manual identify 450P EF Digital / 45244, a 12V battery-clamp setup and a digital control procedure that stops at the operator’s selected tire-pressure target.
- The manual documents a push-on Schrader route and the page lists passenger-car use; the same reviewed arrangement supports the selected power, use, adapter, chuck and target-stop requirements.
- VIAIR lists a 150-PSI maximum working pressure and 100% duty at 100 PSI. Those conditional manufacturer limits distinguish it from the 40243 Digital model, which has a 30%-at-100-PSI rating.
Tradeoffs to weigh
- The 23A maximum, 76.4A inrush at 0 PSI and 40A in-line fuse are separate electrical values; this clamp-powered arrangement is not documented for an accessory socket.
- The product page lists a 30-foot air hose but the dedicated manual describes a 25-foot coiled hose. The current evidence does not settle one definitive length; confirm the exact offer before buying for reach.
- The exact ProductName=45244 SaferProducts.gov query returned an empty array only; this one bounded lookup is not a recall clearance or safety conclusion.
Check these before ordering
- Confirm the seller offers 450P EF Digital / part 45244, not 450P EF Automatic / 45144 or the RV Digital / 45257 package.
- Verify the 12V battery-clamp setup and compare the 23A maximum, 76.4A inrush at 0 PSI and 40A fuse instructions with the current vehicle and compressor manuals.
- Ask which hose length and included kit pieces the exact offer contains; do not count the page’s listed 30-foot hose as settled against the 25-foot manual description.
- Use the vehicle placard or tire maker’s target, follow the manual’s engine-running, attended-use, placement and cool-down instructions, and respect the pressure and duty limits.
