Review the exact 40089 for a compact battery-powered passenger-car top-off where target stopping matters and a two-foot hose can reach the valve. Slime's manual marks flat-to-full crossover and truck/SUV examples Not Advised; its eight-minute claim applies to a P205/55R16 tire from 0 to 35 PSI.

Assessment scenario: Assessment scenario: Slime 40089 rechargeable passenger-car top-offs
A source-based assessment scenario—not the visitor's actual intent—for occasional passenger-car top-offs with an internal battery, selected-pressure stop, Schrader tire connection and press-on head. The two-foot reach, 10-minute run limit, about 25-minute cooling interval and manual's no-advice status for flat-to-full crossover/truck examples remain important constraints.
Explore this buying guide ↗Why consider this model?
- The exact 40089 page/manual document an internal rechargeable battery, a target-stop mode, and a press-on tire head for car use.
- The manual lists 0.3 CFM at zero pressure, two feet of hose, and two car tires from flat to full per charge; those are manufacturer specifications/claims, not independent workload tests.
- The page and manual describe a USB-C charging cable and a roughly four-hour charge from a 2.1A USB outlet; the USB-A wall block is not included.
Tradeoffs to weigh
- The exact manual says not to run more than 10 minutes, allow about 25 minutes of cooling, do not leave the unit unattended, keep the inlet/outlet clear and provide ventilation.
- The two-foot hose limits placement. The exact page and manual conflict on whether the updated green lever lifts or pushes down to lock; inspect the actual head and use the matching instructions.
- Manual-listed 0–150 PSI is display range, not a gauge-accuracy tolerance or maximum-working-pressure rating.
- The page says '2 * 2000 mAh' but the manual specification table says 2,000mAh; the reviewed evidence does not reconcile that wording.
Check these before ordering
- Confirm exact Slime Cordless 3-in-1 Inflator part 40089, not the distinct 40080 or 40084 cordless models.
- Check that the included USB-C cable and ball/tire adapters are present in the exact package; plan to supply a USB-A wall block and 2.1A USB outlet for charging.
- Confirm the two-foot hose reaches the valve while the pump can sit on a stable, ventilated surface; stay present and follow the 10-minute/cool-down instructions.
- Use the vehicle's recommended cold pressure and do not use the manual's P205/55R16 example as a promise for a different tire; the manual marks flat-to-full crossover/truck examples Not Advised.
