How fast does it inflate a large truck tire?

WOLFBOX rates the pump at 58 LPM, which is high for a portable inflator. A large truck or RV tire fills far quicker than with a typical 20 to 30 LPM handheld unit, though exact times depend on tire size and how low it started.

Can I use it while it charges or from the car?

Yes. It runs on its built-in 12,000mAh battery or from a 12V car socket through the 11 ft power cord. The battery itself charges in about an hour.

Does it stop automatically at my set pressure?

It has a preset PSI function and a pressure gauge. You set the target pressure and the inflator fills to it, so you do not have to watch the gauge the whole time.

Is it good for small car or bike tires?

It works, but the high airflow and large battery are aimed at bigger tires. For a compact car or bicycle, a smaller, lighter inflator is easier to carry and store.

What comes in the box?

The inflator, its 20 in air hose and an 11 ft 12V power cord for car-socket use. A charger for the built-in battery is part of the kit.

How does it compare with the standard MegaFlow 24?

The Pro adds the larger 12,000mAh battery and one-hour charging for longer cordless runtime. If you mostly inflate one car's tires, the smaller model covers it; for trucks, RVs or several tires per session, the Pro's extra capacity matters.
