Consider the 40047 only for a socket-powered passenger-car plan with a verified 15A-capable outlet, user-selected stop and enough reach for your setup. Its 10-foot cord plus 2-foot hose gives 12 feet of stated reach; no working-pressure ceiling or accuracy tolerance is documented.

Assessment scenario: 15A-capable socket-powered car top-off with preset stop
A source-based assessment for a driver with a confirmed 12V accessory outlet rated at least 15A, who can run the engine, wants user-selected stopping and accepts the exact model’s short hose and run/cool limits. The maker’s four-minute figure applies only to its named P205/55R16, 0-to-35-PSI scenario; this does not certify tire or vehicle compatibility.
Explore this buying guide ↗Why consider this model?
- The exact 40047 page/manual documents a 12V accessory outlet, passenger-car tire route, press-on tire head and Inflate-Right selected-pressure stopping.
- Its package marks car use, and its manual specifies a 10-foot lead, 2-foot hose and 12-foot total reach.
- Its ball needle and separate ball route do not make this car-tire scenario a universal fit or pressure guarantee.
Tradeoffs to weigh
- The manual requires an outlet rated at least 15A, recommends a running engine and warns against older 8A outlets; it also says not to start the vehicle while the pump is plugged in.
- Operation is limited to 10 minutes followed by about 25 minutes cooling; the manual says not to leave it unattended.
- The 0–99 PSI display is not a working-pressure rating or gauge-accuracy statement; no maximum working pressure is established. The page/manual green-lever lock directions conflict.
- The four-minute claim is one P205/55R16 0–35 PSI maker scenario, not an independent result or general fill-time forecast.
Check these before ordering
- Verify that the vehicle manual rates the accessory outlet at 15A or higher; do not replace a fuse with a larger one.
- Confirm the offer is Slime Rugged Digital Tire Inflator part 40047, not Slime 40080 or another similarly named pump.
- Check that the exact lever and instructions match the included tire head; Slime’s page and linked manual show conflicting lock directions.
- Compare the tire’s vehicle-placard cold pressure with the actual task; the display range does not establish pressure accuracy or an upper operating limit.
