Bottom Line

The CRAFTSMAN V20 Cordless Tire Inflator (CMCE521B) is a powerful, portable, and user-friendly tool ideal for most vehicle and sports equipment inflation needs. Its compatibility with the Craftsman V20 battery platform makes it a perfect addition for those already invested in the system. Keep in mind the need to continuously hold the trigger and the lack of a forward-facing valve light, which might impact ease of use in some situations. If you want a reliable cordless inflator with solid digital accuracy and good battery efficiency, this model fits the bill nicely. Just remember you’ll need to have or buy the V20 battery separately before you can get started.
