Fill speed and accuracy
Fill time from 28 to 35 PSI on a P235/55R18: Milwaukee M12 2475-20 1m 10s, Ryobi P737D 1m 35s, Fanttik X8 Apex 2m 5s, Avid Power 2m 50s, Viair 88P 3m 20s. The cordless tool brands (Milwaukee, Ryobi) win on speed because they're powered by 12V/18V tool batteries — true high-output.
PSI accuracy at 35 PSI target (vs calibrated reference gauge): Milwaukee 35.1 PSI, Ryobi 34.8, Fanttik 35.4, Avid Power 33.8, Viair 36.2. Milwaukee and Ryobi are within 0.5 PSI; Avid Power and Viair drift 1-2 PSI.
Year-long durability
After 12 months of garage use: Milwaukee M12 and Ryobi P737D no issues, full warranty backed by tool brands. Fanttik X8 Apex hose seam started leaking at 8 months (replaceable hose). Avid Power handle plastic cracked at 10 months. Viair 88P (12V cigarette plug) still works but the plug connector is intermittent.
Battery brand commitment: Milwaukee runs on M12 tool batteries (~$100 for a 4Ah pack). Ryobi runs on 18V ONE+ batteries. If you already own tool batteries from either brand, those inflators are a no-brainer. If not, the cost of entry includes the battery.
Power source matters
Cordless tool-battery (Milwaukee, Ryobi): fastest and most accurate. Best for serious users with existing tool batteries.
Cordless standalone (Fanttik, Avid Power): integrated battery, USB-C charging. More portable but slower fill, less accurate.
12V cigarette plug (Viair): slowest and least accurate, but works on any car without batteries. Best emergency-only pick.
