CarCareTruth's Analysis
Last reviewed May 27, 2026
TL;DR Flat-fill speed is unverified — one test measured the 25-to-35 PSI top-off at ~3:50, not a flat tire. Gauge reads within ±1 PSI of a calibrated reference per one independent source.
What it is and how it performs
The AstroAI C2 is a 20V cordless handheld tire inflator with a metal pump cylinder, backlit LCD, and preset auto-shutoff. It ships with a 20V 2.0Ah Li-ion battery, a 12V DC backup cable, a storage bag, and valve adapters for bikes and motorcycle tires. Reviewers consistently report filling four passenger-car tires on one charge with battery remaining. The 160 PSI rating covers cars, motorcycles, and light trucks; no independent test at 120+ PSI was found to confirm the upper range.
Who should buy this — and who should skip it
Good fit for a driver who wants a cordless trunk inflator for monthly pressure checks and occasional roadside use. Skip it if third-party electrical certification matters — no UL or ETL listing was found.
Safety and environmental impact
No UL, ETL, or CE listing was found; no CPSC recall exists for this model. The 20V Li-ion battery pack is removable; recycle it via Call2Recycle or a retailer drop-off, not household trash.

Buy it!
One of the best things I've ever bought with my money. It has a built in flashlight with helps if I need to air up a tire when it's getting dark or is dark. It comes with a carry case with is awesome. Definitely buy it's perfect for emergencies! It comes with two different types of batteries one that plugs directly into your cars outlet OR if u don't have an outlet in ur car (u know the old fashion cigarette lighter outlet) it has a rechargeable battery! It tells you how much air is in the tire and comes with multiple attachments as well so it can air up basketballs, bike tires, ect. It shuts off automatically when it reaches desired air pressure. It's really easy to use and turn on. It's just hands down a really great tool!
