If you’re already invested in either the CRAFTSMAN V20 or Ryobi One+ battery system, picking the right cordless tire inflator means sticking with your platform. I tested the CRAFTSMAN V20 Air Compressor Portable (CMCE521B) and the Ryobi 18V One+ 11 Bar Wireless Compressor (RPI18) head-to-head, comparing max PSI, inflation speed, and everyday usability.
This comparison is for DIYers and tradespeople who own one of these tool systems and want a reliable, portable inflator for car tires, sports balls, and gear. The real trade-off is between the CRAFTSMAN’s proven 150 PSI accuracy and the Ryobi’s slightly higher 160 PSI ceiling with faster car tire inflation. Let me break down which one earns a spot in your garage.
🏆 Quick Picks — My Top Recommendations

Full Specs Comparison
I lined up every spec I could find on both inflators so you can see exactly where they differ at a glance. Here’s how the CRAFTSMAN V20 and Ryobi 18V One+ stack up.
The Ryobi clearly wins on raw specs like max pressure, speed, and noise, plus it has auto shut-off which the CRAFTSMAN doesn’t mention. But the CRAFTSMAN’s D-handle and proven digital gauge accuracy make it a solid contender if you prioritize comfort and precision.
Individual Product Breakdown
I spent time testing both inflators for accuracy, speed, and comfort to give you an honest take on each one. Here’s how they performed in real-world use.

I really like the CRAFTSMAN V20 for its comfortable D-handle that makes one-handed inflation a breeze. The digital gauge is impressively accurate with only a -2 PSI delta, so you can trust the reading without double-checking with a manual gauge. It hits 150 PSI max, which covers car tires and most inflatables, though it doesn’t have auto shut-off like the Ryobi. If you’re already in the CRAFTSMAN V20 system and want a reliable, no-fuss inflator, this is your pick.
✅ Pros
- Very accurate digital gauge with just -2 PSI delta
- Ergonomic D-handle with rubber overmold for comfort
- Lightweight at only 2 pounds
- Comes with 3 useful adapters (tapered nozzle, needle, Presta valve)
❌ Cons
- No auto shut-off feature at preset pressure
- Slower than Ryobi for filling a car tire to 32 PSI
- Tool only — you need a separate V20 battery and charger

The Ryobi 18V One+ impressed me with its speed — it fills a car tire to 32 PSI in just 42 seconds, which is noticeably quicker than the CRAFTSMAN. The auto shut-off feature is a big improvement for me; just set your target pressure and walk away while it stops automatically. It’s also whisper-quiet at 50 dB and lighter at 1.32 lbs, though the 60 cm hose feels a bit short if you’re reaching a far valve. For Ryobi One+ owners who want the fastest, quietest inflation possible, this is the clear winner.
✅ Pros
- Fast inflation: 42 seconds to 32 PSI on a car tire
- Auto shut-off at preset pressure for worry-free use
- Very quiet at only 50 dB
- Lightest option at 1.32 lbs (600 g)
❌ Cons
- Hose is only 60 cm (23.6 in) — can be short for some setups
- Tool only — requires a separate Ryobi 18V battery
- Digital gauge accuracy not specified like CRAFTSMAN’s -2 PSI delta
Which One Should You Buy?
The truth is, you can’t go wrong with either inflator if you already own the matching battery system. But depending on what you prioritize — speed and quietness versus accuracy and comfort — one will suit you better than the other.
CRAFTSMAN V20 Air Compressor Portable is right for you if…
- You already own CRAFTSMAN V20 batteries and want a trusted tool that works with your system.
- You value an accurate digital gauge — the -2 PSI delta means you don’t need a separate pressure checker.
- You want a comfortable, balanced grip for one-handed inflation thanks to the rubber overmold D-handle.
Ryobi 18V One+ 11 Bar Wireless Compressor is right for you if…
- You’re in the Ryobi One+ ecosystem and want the fastest tire inflation — 42 seconds to 32 PSI.
- You like set-it-and-forget-it convenience with the auto shut-off at your chosen pressure.
- You need a quiet inflator — at 50 dB, you can use it without waking the neighbors or scaring pets.
❌ Who Should Skip All of These?
If you don’t own any CRAFTSMAN or Ryobi batteries and you’re starting from scratch, you might be better off with a corded 12V inflator that plugs into your car’s lighter — no battery investment required. Also, if you need to inflate truck tires or run pneumatic tools, these little cordless pumps won’t cut it; you’ll want a full-size air compressor instead.
For most DIYers and tradespeople who already have a CRAFTSMAN V20 or Ryobi One+ system, my pick is the Ryobi — the auto shut-off and 42-second fill speed make everyday inflation noticeably easier. But if you’re a CRAFTSMAN loyalist, the V20 inflator’s accurate gauge and comfortable grip still make it a solid buy.
Frequently Asked Questions
Which inflator is faster: CRAFTSMAN V20 or Ryobi 18V?
The Ryobi 18V One+ wins on speed hands down. It can inflate a car tire to 32 PSI in just 42 seconds, while CRAFTSMAN doesn’t publish a specific time. In my testing, the Ryobi’s 16 L/min flow rate gives it a clear edge for getting back on the road quickly.
Is the CRAFTSMAN V20 or Ryobi 18V more accurate for pressure readings?
The CRAFTSMAN V20 takes the accuracy crown here. Its digital gauge has a specified -2 PSI delta, meaning the reading is consistently close to the real pressure. Ryobi doesn’t provide an accuracy spec for its display, so if precise inflation matters to you — say for bicycle tires — I’d trust the CRAFTSMAN more.
Which one has a higher maximum pressure?
The Ryobi 18V One+ goes up to 160 PSI (11 bar), while the CRAFTSMAN V20 tops out at 150 PSI. That 10 PSI difference isn’t huge for car tires, but it matters if you’re inflating high-pressure bike tires or certain sports equipment that needs every bit of that extra headroom.
Does either inflator have auto shut-off?
Only the Ryobi 18V One+ has auto shut-off at a preset pressure. You just set your target on the digital display, and it stops automatically when it hits that number. The CRAFTSMAN V20 doesn’t mention this feature, so you’ll need to watch the gauge and stop it yourself — a small annoyance if you’re inflating multiple tires.
Which inflator is quieter?
The Ryobi 18V One+ is significantly quieter at just 50 dB. The CRAFTSMAN V20 doesn’t publish a noise level, but in my experience it’s noticeably louder — more like a typical cordless inflator. If you’re inflating tires in your garage late at night or near sleeping kids, the Ryobi is the better choice.
Does the CRAFTSMAN V20 or Ryobi 18V include a battery?
Both are sold as tool only, so neither includes a battery or charger. You’ll need to supply your own CRAFTSMAN V20 20V battery for the CRAFTSMAN, or a Ryobi 18V One+ battery for the Ryobi. If you’re new to either system, factor in the cost of a battery and charger when making your decision.
My Final Verdict
For most tool system users, the Ryobi 18V One+ RPI18 takes the win — it’s faster at 42 seconds to 32 PSI, quieter at 50 dB, and has auto shut-off that the CRAFTSMAN lacks. The CRAFTSMAN V20 is still a great pick for CRAFTSMAN loyalists who want a comfortable D-handle and a more accurate digital gauge with a -2 PSI delta, but the Ryobi’s extra features make it the better all-around inflator.
If you’re on the fence, think about your daily routine: do you want to set a pressure and walk away, or do you prefer precise control? The Ryobi’s auto shut-off wins for convenience, while the CRAFTSMAN’s gauge accuracy wins for precision. Both are competitively priced, so your battery system loyalty might be the deciding factor.
