CRAFTSMAN V20 Air Compressor CMCE521B

V20 Cordless High-Pressure Inflator for tires, sports gear and inflatables. Up to 150 PSI, digital gauge ±2% accuracy, onboard accessory storage and cordless portability.

You get a compact, battery-powered inflator that fits in the trunk or your tool bag and handles everything from bike tires to car tires and pool toys. The digital gauge helps you set exact pressure values so you do not second-guess whether a tire is safe, and the onboard storage keeps the tapered nozzle, needle and Presta adapter within reach. Because it is part of the V20 ecosystem, it pairs neatly with existing Craftsman batteries and frees you from hunting for an outlet when you need a quick top-up.

It is especially handy for weekend trips, roadside touch-ups and routine maintenance when portability and simplicity matter most.

What People Say

You will see a lot of praise for how portable and convenient this inflator is, particularly from people who already own V20 batteries. Customers commonly note the clear digital display, the flexible hose that makes attachments easy, and the handy onboard storage for adapters.

On the flip side, many mention that the tool is sold without a battery and that there is no trigger lock, so you have to hold the trigger while inflating.

FAQ

Do I Need a Battery?

Yes, this model is sold as a tool only, so you will need a compatible Craftsman V20 battery to run it. If you already own V20 tools you can swap batteries, and if you plan to inflate multiple tires in one session use a higher-capacity V20 pack for longer runtime.

How Accurate Is the Pressure Reading?

The built-in digital gauge is rated at ±2% accuracy, so it gives you a dependable readout for routine checks and top-ups. For critical checks you can cross‑verify with a trusted handheld gauge, but for everyday use the digital display should be sufficiently precise.

Any Practical Drawbacks Or Tips?

You should know there is no trigger lock, so you will have to hold the trigger while inflating which can be tiring for long fills; bring a friend or plan short bursts for larger tires. The hose is flexible and the unit stores adapters onboard, making attachments simple, and the 150 PSI capacity handles most car and bike needs—just monitor battery charge and allow the tool to cool if you do several fills back to back.

Why Customers Choose

You pick this inflator because it merges cordless convenience with the Craftsman V20 battery ecosystem, so you can grab it from your toolbox and use it anywhere without hunting for an outlet. The compact, lightweight design, flexible hose, onboard adapter storage and an accurate digital gauge (±2%) make it easy for you to handle car tires, bikes and sports gear reliably.

Wrapping Up

If you already use Craftsman V20 batteries and want a small, accurate inflator for cars, bikes and sports equipment, the CMCE521B is a solid fit. It reaches up to 150 PSI, offers a digital gauge accurate to ±2%, and stashes a tapered nozzle, needle and Presta adapter onboard so you keep everything together. At about 2 pounds with a flexible hose and low operating noise, it is convenient for roadside or recreational use. There are two practical drawbacks to note: the tool is sold as tool only so you need a V20 battery to run it, and there is no trigger lock so you must hold the trigger during inflation.

For routine maintenance and occasional emergency top-ups, this Craftsman inflator gives you trustworthy, portable performance that integrates easily into the V20 ecosystem.
