AstroAI MC3 Multifunctional Tyre Inflator, 20V Battery, AC and 12V DC

Multifunctional: AstroAI MC3 is a multi-power tyre inflator and air pump with separate high-pressure and large-volume modes. Its listed 20V battery, mains and 12V DC options suit users who want to inflate tyres and low-pressure inflatables with one unit, while the two modes and listed exclusions matter when choosing it for a particular job.

At a glance

Three listed power options include a rechargeable battery, AC mains and a 12V DC connection.
Separate high-pressure and large-volume modes address tyre inflation and low-pressure items such as air mattresses and rafts.
The digital display shows preset and current pressure, and the unit is claimed to stop automatically at the selected pressure.
A memory function retains the last pressure setting, and an integrated LED torch is listed.
The manufacturer says large-volume mode reaches 350L/min and high-pressure mode reaches 160 PSI. These are mode-specific claims, not interchangeable measures.

Pros and cons

Pros

Multiple power options offer flexibility for home, vehicle and outdoor use.
The separate high-pressure and high-volume modes make the pump relevant to both tyres and larger low-pressure inflatables.
Preset pressure, automatic stop and memory may simplify repeat tyre top-ups.
The listed kit includes a battery and several adapters for different valve and inflatable types.

Cons

The manufacturer says it is not suitable for heavy-duty trucks.
The claimed continuous-use limit is up to 20 minutes, so it is not presented for prolonged uninterrupted operation.
Customer feedback is mixed on battery compatibility and connectivity, which may matter to buyers relying on the battery or related connections.
