I have the DeWalt tire inflator too. It's great if you are already using their 20V system and runs a long time on even a tiny 2Ah battery pack. I also use it to inflate pool toys and it works on an inflatable kayak too. It doesn't move a massive amount of air so I find it a bit slow for big truck tires but it works great for trailer tires. I always carry it with me whenever we tow.
