Product description
This portable cordless tire inflator brings fast, accurate inflation to the garage, trunk, or job site. The Craftsman CMCE521B combines battery powered convenience with a digital pressure gauge for clear readings, and it supports up to 150 PSI for a broad range of uses. If you need a compact pump that reduces trip time and lets you top off tires or other inflatables without cords, this model covers that need while staying easy to handle and store.
Quick overview
The main advantage here is mobility, paired with a clear, easy to read display that reports pressure with a small delta according to the manufacturer. It has an optimized D-handle with rubber overmold for comfort and balance, which helps during longer jobs or when working at awkward angles. Small enough to keep in a trunk, yet powerful enough to tackle larger tires, it fits into a Craftsman V20 tool ecosystem for shared battery use. Need something that travels well and still hits useful pressure levels?

Who it’s for
It’s a great fit if you want portable inflation for roadside emergencies, seasonal tire maintenance, or filling sports gear with minimal setup. Commuters who carry a compact pump for peace of mind will appreciate the lightweight handling and clear display, and DIYers who already own V20 batteries benefit from cross compatibility.
It may not be a great match if you expect a kit with batteries or chargers included, because this listing is tool only. Also, if you need continuous heavy duty inflation for commercial workloads, a corded shop compressor could be more suitable.
What you’ll notice day to day
Expect straightforward operation and a short learning curve when reading the digital gauge and setting desired PSI. The rubberized D-handle reduces hand fatigue, and the digital readout gives confidence during inflation tasks. A subtle limitation to note is that battery life varies with use and load, so keep track of charge when planning multiple inflations. Overall this Craftsman unit focuses on portability, clear pressure feedback, and compatibility with the V20 family, making it a useful addition to a mobile toolkit. 🔋📏
