Can it inflate a basketball or bike tire?

No. Its flow is only 1.5 to 4.0 LPM and the 4.5 mm nozzle is small, so it is far too slow for inflating balls or tires. It is meant for vacuum and low-flow pressure tasks.

What do I need to run it?

A regulated 12V DC supply that can deliver the 3.6 W draw, plus tubing or an adapter that fits the 4.5 mm nozzle. The pump itself has no switch, plug or hose.

How loud is it in use?

The rating is under 65 dB, which is quiet enough to sit on a workbench. Expect a soft hum rather than silence.

Can it run continuously?

The maker rates it for more than 500 continuous hours. Long runs are fine, but keep the motor ventilated and avoid blocking the nozzle.

Does it work as a vacuum and as a pressure pump?

Yes. Depending on which port you connect, it pulls vacuum or pushes air, with a maximum pressure of 80 kPa.

Our take on the M Buder 12V Miniature DC Air Pump Electric Vacuum Pump

The M Buder is a tiny 12V DC diaphragm pump that moves 1.5 to 4.0 LPM of air and pulls up to 80 kPa of pressure through a 4.5 mm nozzle. It runs on 3.6 W and is rated under 65 dB, with a claimed life of more than 500 continuous hours. It suits hobbyists and repairers who need a small vacuum or pressure source inside a project, not a pump for inflating basketballs or tires. Against aquarium and medical-style micro pumps it is cheaper and simpler, but it has no battery, switch or gauge, so you supply the 12V power and the plumbing.
