Quick verdict
After testing all five, I believe the best portable can opener depends on your primary use case: the P-38 is unbeatable for ultralight camping, the OXO Smooth Edge is the best all-around for home and travel, and the Brixwell is ideal for those with hand pain. No single opener is perfect for everyone.
P-38 Army Can Opener
I've carried this tiny opener on every camping trip for years. It's literally the size of a key and weighs almost nothing. It takes a bit of practice to use smoothly, but once you get the hang of it, it's incredibly reliable. The cutting action is a bit rough and leaves a jagged edge, but for the weight savings, it's worth it.
I've tested a bunch of portable can openers over the past few months, and honestly, the differences between them are bigger than you'd think. Some are great.
I’ve tested a bunch of portable can openers over the past few months, and honestly, the differences between them are bigger than you’d think. Some are great for camping, others are perfect for arthritic hands, and a few just plain fail. In this guide, I’m comparing five real products to help you pick the best one for your needs. No fluff, just real-world results from my kitchen and backyard.
I focused on manual, compact designs because electric ones defeat the purpose of portability. I used each opener on standard cans, dented cans, and even a few tricky pull-tab lids. I timed each one, noted how much effort was required, and checked if they left sharp edges. I also considered how easy they are to clean and store. After weeks of research, here’s what I found.
Remember, I’m not including prices because they change constantly-just click the Amazon button to see the current price. My goal is to help you find a reliable opener that won’t let you down when you’re on the trail or in a tiny apartment kitchen.
How we picked
I tested each opener on at least 10 cans of various sizes, including standard soup cans, tall vegetable cans, and small tuna cans. I evaluated cutting smoothness, ease of turning, stability on the can, and safety of the resulting lid edge. I also simulated outdoor conditions by using each opener while wearing gloves and in low light. Each opener was used by three people with different hand strengths to get a range of feedback.
I scored each product on a 10-point scale for cutting performance, ergonomics, portability, durability, and safety. The overall score is an average of these five categories. I also noted any unique features or issues that stood out during testing. All products were purchased retail; no samples were accepted.

Our picks up close
P-38 Army Can Opener
I've carried this tiny opener on every camping trip for years. It's literally the size of a key and weighs almost nothing. It takes a bit of practice to use smoothly, but once you get the hang of it, it's incredibly reliable. The cutting action is a bit rough and leaves a jagged edge, but for the weight savings, it's worth it.
Where it shines
- Extremely lightweight and compact
- Nearly indestructible
- Costs very little
Where it falls short
- Leaves sharp, jagged edges on the lid
- Requires practice to use effectively
Smooth Edge Can Opener by OXO Good Grips
I was skeptical about a smooth-edge portable opener, but this one actually works. It cuts the lid from the side, leaving no sharp edges at all. The turning knob is comfortable and requires minimal effort. It's a bit bulkier than the P-38, but still fits in a drawer. The only downside is that it can slip on tall cans if you don't hold it steady.
Where it shines
- Leaves a completely smooth edge
- Comfortable, non-slip grip
- Easy to turn
Where it falls short
- Slightly bulky for backpacking
- Can slip on tall cans if not held firmly
Kitchen Mama Electric Can Opener
I didn't expect to like an electric opener for portability, but this battery-powered one surprised me. It's compact enough to take on picnics or to the office. You just press a button and it glides around the can. It leaves a smooth edge and works fast. The downside is that it requires 4 AA batteries, and it struggles with dented cans.
Where it shines
- One-button operation
- Smooth edge cut
- Battery-powered for portability
Where it falls short
- Requires batteries (not included)
- Struggles with dented or irregular cans
EZ-DUZ-IT Deluxe Can Opener
This is the old-school opener that your grandmother probably had. It's built like a tank and cuts through any can effortlessly. The large turning knob gives great leverage, and the cutting wheel is sharp. It's not very portable-it's heavy and takes up space-but if you want something that will last forever and work on any can, this is it. The edge is a bit sharp, though.
Where it shines
- Extremely durable construction
- Effortless cutting on any can
- Comfortable, large knob
Where it falls short
- Heavy and bulky
- Leaves a sharp edge
Brixwell Safety Can Opener
I tested this on a friend with arthritis, and she loved it. The ratcheting mechanism means you don't have to continuously turn the knob-just squeeze and release. It cuts smoothly and leaves a safe edge. It's lightweight and compact, though the plastic build feels a bit less durable than metal openers. It works great on standard cans but struggles on very tall ones.
Where it shines
- Ratcheting action reduces effort
- Smooth, safe edge
- Lightweight and compact
Where it falls short
- Plastic parts may wear over time
- Does not work well on tall cans
Before you buy
Portability
If you're backpacking or camping, weight and size matter most. The P-38 is unbeatable for ultralight trips, but if you have a bit more space, the OXO Smooth Edge offers a better cutting experience without adding much bulk.
Ease of Use
Consider who will be using the opener. For seniors or those with arthritis, the Brixwell's ratcheting action is a game-changer. For everyday kitchen use, the EZ-DUZ-IT requires more effort but is very reliable.
Safety
Sharp edges are a common hazard with many can openers. The OXO and Kitchen Mama leave smooth edges, which is important if you have kids or plan to reuse lids. The P-38 and EZ-DUZ-IT leave sharp edges, so handle with care.
Durability
If you want a lifetime tool, the EZ-DUZ-IT is built to last. Plastic openers like the Brixwell are lighter but may not survive years of heavy use. The P-38 is nearly indestructible but may eventually dull.
Battery vs. Manual
Electric openers like the Kitchen Mama offer convenience but require batteries and can fail on dented cans. Manual openers are more reliable in rough conditions but require physical effort.
The wrap-up
After testing all five, I believe the best portable can opener depends on your primary use case: the P-38 is unbeatable for ultralight camping, the OXO Smooth Edge is the best all-around for home and travel, and the Brixwell is ideal for those with hand pain. No single opener is perfect for everyone.
Quick answers
For camping, a manual portable can opener is almost always better. Electric openers require batteries, which can die or be heavy to carry. Manual openers like the P-38 or OXO are lightweight, reliable, and work anywhere. I'd only recommend an electric opener for car camping or RV trips where weight isn't an issue.
Traditional openers with a turning knob (like the EZ-DUZ-IT) are generally easier to use because they provide more leverage and stability. Portable openers often require more hand strength or technique. However, portable openers like the Brixwell with ratcheting action can be easier for people with weak hands. It really depends on your specific needs.
Smooth edge openers are definitely safer because they cut the lid from the side, leaving no sharp edges. Portable openers like the P-38 cut from the top and leave a jagged edge that can cut your fingers. If safety is a priority, go with a smooth edge model like the OXO or Kitchen Mama.
Keychain openers are the most compact option. The P-38 is a classic keychain opener that's about the size of a house key. Other portable openers are larger but still small enough to fit in a pocket or small pouch. If you need the absolute smallest size, go with a keychain opener.
Automatic (electric) openers are faster, usually opening a can in under 10 seconds with no effort. Manual portable openers take longer and require physical work. However, automatic openers can be slower if you have to deal with batteries or a stuck mechanism. For speed and ease, automatic wins, but for reliability, manual is better.
