Frequently asked questions
The tire inflator’s capacity should match the tire size. For large tires, opt for a high-capacity inflator to minimize inflation time. Conversely, a lower-capacity inflator is better for vehicles with smaller wheel diameters.
A tire inflator is a small, tank-less air compressor that’s usually kept in a car and is suitable for inflating tires or other small inflatables. An air compressor is usually much larger and has a higher air output and typically a tank, making it more versatile.
If you’re running the inflator off your vehicle’s 12V system, then yes. To avoid this, keep the vehicle running while in use.
Battery-powered items stored in cars are often forgotten about. If you store any battery-powered devices in your car, such as an inflator or jump starter, it’s best practice to fully charge the battery every few months to keep the battery charged and extend its lifespan.
