A great litttle compressor. It can inflate two - 255 75 R17 (32 tire) from 15 psi to 40 psi in 10 minutes, which is the continuous runtime limit. I like the digital readout of the PSI, and it is accurate enough based upon my tire guage and TPMS readout. The PSI limit is also a handy feature as you can walk away and know that it won't be overinflated.Two thing I would change: In the manual it just states the continuous runtime is 10 minutes. Usually that is given for a set PSI, so for inflating tire at a lower PSI, you should be able to run the compressor for longer. However, without that extra detail, you should switch off after 10 mins regardless of whether it had additional thermal headroom. Two, the battery leads are a little short making it a small stretch to reach the far side, rear tire.Small changes for a compressor that costs a fraction of the other heavy duty ones.
