18V Cordless Car Tyre Inflator for DeWalt / Makita

Yes, it can inflate a completely flat car tyre, though it will take longer than a partially inflated one. The pump is capable of reaching typical car tyre pressures (30–40 PSI) from 0 PSI. Users report successfully inflating flat passenger car tyres in 5–10 minutes depending on tyre size and starting pressure. For best results, start in a safe location and monitor the digital display. It’s not as fast as a garage compressor, but it’s reliable for emergency roadside use or when no other options are available.

With a typical 5.0Ah 18V battery (not included), you can expect to inflate 4–6 standard passenger car tyres (from ~15–20 PSI to 35–40 PSI) on a single charge, or 8–12 bike tyres. Smaller items like sports balls or inflatables use much less power, so you can inflate dozens. Runtime varies with tyre size, starting pressure, and ambient temperature. The 3.0Ah battery version (if used) will handle roughly 60–70% of that capacity. Always carry a spare battery for longer trips or multiple vehicles.

Yes, it is suitable for most SUV and light van tyres. It can reach the typical required pressures (35–50 PSI) for these vehicles. Inflation time is longer than for standard cars (around 6–12 minutes per tyre from low pressure) due to larger volume. Users commonly use it successfully on SUVs, crossovers and small vans. For heavy commercial vans or very large tyres requiring 60+ PSI, a more powerful compressor is recommended. The auto-stop function helps prevent over-inflation.

Yes, it features an auto-stop function. Once the set pressure is reached, the pump automatically shuts off, preventing over-inflation and allowing hands-free operation. You can set your desired pressure (in PSI, BAR, KPA or KG/CM²) on the clear digital display before starting. The unit also has overheat protection to ensure safe, reliable use. Users appreciate this feature for convenience and peace of mind, especially when inflating multiple tyres or working alone.
