RIDGID 18V Digital Inflator

The manufacturer claims it's the 'fastest truck tire fill from flat to full' but does not cite a specific time. One independent review by Pro Tool Reviews measured approximately 90 seconds from under 20 PSI to 35 PSI on a passenger-car tire — but that was a top-off test, not a flat-to-full fill. No independent flat-to-35-PSI timing tests on a standard P215/65R17 starting from 0 PSI have been located as of May 2026. The 150 L/min flow rate is higher than most 12V corded competitors, which is consistent with faster-than-average fill times.

Community cross-checks suggest the onboard gauge reads consistently high — multiple Home Depot verified-purchase reviewers report approximately 5 PSI above three separate external gauges, with one tester specifically comparing against three different external gauges that all agreed with each other. A separate chuck-seating issue (ensuring the quick-connect is firmly seated before reading) may account for some variance. Until a calibrated reference-gauge cross-check is published by an independent tester, verify your target pressure with a separate gauge after inflation.

No UL Listing or ETL Certification has been confirmed for model R87044 as of May 2026. Searches of UL Product iQ and the Intertek ETL directory were inconclusive (database access issues prevented completion). The operator manual does not display UL or ETL marks. No active CPSC recall is on file for this model.

Yes — the R87044 is compatible with the full RIDGID 18V Li-ion battery platform. Battery and charger are sold separately. The listing is not eligible for RIDGID's Lifetime Service Agreement (LSA).

With some patience. The operator manual specifies a 5-minute-on / 5-minute-off duty cycle. At typical passenger-car fill times, you can inflate one or two tires before the required cooldown. A full 4-tire rotation will require at least one 5-minute break. This is a real limitation compared to higher-duty-cycle garage compressors.
