My take is that if you need to use one of these small, lightweight battery inflators for more than 10 minutes, the tool is too small for the job.Cool for 40 after 20mins ouch. While tires not an issue, could be for blowing up a ton of pool toys & air mattresses
Maybe buy a Ryobi 1 gallon 18V compressor. I had one and thought it was decent. I have the 2 gallon M18 compressor and it is probably 4 times the size and weight. I usually reach for the lightest/easiest for tires, if just topping off, and that is the little M12.
