Which inflates faster, the ROCGORLD R8 or the AstroAI?

The ROCGORLD R8 is significantly faster — it pushes 40 liters per minute compared to the AstroAI's 1.23 liters per minute. In my testing, the R8 took a 215/50 R17 tire from 26 to 35 PSI in under a minute, while the AstroAI would take several minutes for the same job. If speed is your top priority, t

Is the AstroAI worth buying over the ROCGORLD R8?

Do these inflators work while the car is off?
