Last Updated on
Last updated on

We analyzed and compared 12 different can openers from 2 manufacturers (Black&Decker and Proctor Sillex), and  that are available on the market right now. We picked the Black & Decker CO85 Spacemaker as the best under counter can opener for most people. It comes with a bag cutter, a bottle opener, and a knife sharpener.

We also like the Black & Decker CO100B which comes in modern black design and is the most affordable under counter can opener we managed to review.

Under the counter vs stand alone can opener

There are two main types of electric can openers.

Stand alone can openers are those little tiny devices that you can put on the counter or in the drawer because they are small and compact. They are usually powered by batteries which makes them appropriate for camping. Besides portability their their biggest advantages is the price. Most of them cost below $30 and they are appropriate for almost every budget.
Under the counter (cabinet) can openers are larger and usually more powerful than “stand alone” battery powered electric can openers. They are designed to be installed under the kitchen counter which saves space on the counter. They usually feature a powerful motor that is often very durable and appropriate for heavy-duty use. Many of them also come with additional handy tools such as knife sharpeners, bottle openers, and kitchen shears. Their main disadvantage is the price which can go all the way up to $200.

Editor’s choice

Black & Decker CO85 Spacemaker

  • Power pierce cutter
  • Appropriate for big and tall cans
  • Hands free operation
  • In-built knife sharpener and bottle opener
  • Quite expensive
  • Dimensions: 9 x 14 x 3 inches
  • Weight: 2.7 lbs
  • Color: white

There are plenty of can opener manufacturers fighting for the spot to dominate the market. If there is a single one that stands out, it has to be the Black and Decker; an American manufacturer that currently has about 30.000 employees.

Most Black & Decker products are known for long lifespan and attractive warranty coverage which really tells a lot about the quality of their products. If you spend a few hours searching for opinions about Black & Decker online, it won’t take long before you find an enthusiast telling you that their 20+ years old Black & Decker appliances owned by their grandparents still work like brand new.

We picked the CO85 Spacemaker as the best under the counter can opener out of 12 we have reviewed. It can be mounted directly under the counter and comes with a lot of handy features.

The motor runs smoothly and has enough power for heavy-duty work. The power pierce blades are strong enough for opening big and tall tall or small cans and we believe that this is can opener is the most appropriate for commercial use out of all can openers we were able to analyze.

It also comes with a power pierce cutter, a knife opener, and a bottle opener. The only downside of the Black & Decker product is the price. But despite the fact that the CO85 Spacemaker is one of the more expensive tin openers, it’s an investment that is probably the best.

Despite the fact that the CO85 is not the newest can opener of the Black&Decker Spacemaker can opener series and it has been on the market for a long time, it’s one of the most popular can openers on the market judging by numerous customer testimonials online. It feel sturdy and well built and it seems that it can last a lifetime.

The downside of the CO85 is the hefty price tag. It costs more than most “stand alone” can openers on the market and it even more than many newer Black & Decker can openers.

Best budget pick

Black & Decker CO100B

  • Affordable for an under the counter can opener
  • Multi-functional
  • Modern design
  • Hands-free operation
  • Auto shutoff function
  • Only available in black design
  • Dimensions: 6.5 x 7.5 x 5 inches
  • Bag cutter
  • Knife sharpener
  • Bottle opener
  • Feature 5

The CO100B can opener is a younger and smaller brother of the CO85. It’s one of the rare under the counter can openers that don’t cost over $100 which makes it an interesting choice for tight budgets. Let’s be real, $100 or even $200 for an electric can opener is way too much for most of us.

It comes in all black design and it’s packed with all of the features you could expect from the highest price range. Just like its older brother, it has an in-built bag cutter, a bottle opener, and a knife sharpener.

To use it, simply position the can, press on the power button and the device will do the rest. The power pierce cutter will pierce through most lids in a matter of seconds and once the lid is opened, the CO100B will automatically shut off.

Many older electric can opener were quite dangerous to use and many of them wouldn’t be banned from the market right now. All the sharp parts of the CO100B are enclosed in a swing-open-door which (if used correctly) prevents possible injuries.

If you don’t want to spend too much money on the most expensive can openers with enormous amount of features out there, the CO100B can be an ideal under the counter can opener to start with. Although it’s cheaper than most under the counter can openers we analyzed, it has a few disadvantages over the CO85. It doesn’t feel as sturdy and judging by several consumer reviews, it doesn’t live up to the quality of the CO85. “Don’t fix what isn’t broken” phrase comes in mind .

Proctor Silex 75400 PowerOpener


  • Easy to mount
  • 3 appliances in 1 package
  • Dishwasher safe removable cutting lever

  • Quite expensive
  • In-built bag slitter and bottle opener
  • Cord storage
  • Easy to install
  • Automatic shut-off function
  • Dimensions: 6.9 x 4.8 x 6.8 inches

While it seems that the Black & Decker has very little competition in the under the counter electric can opener market, the Proctor Silex 75400 (E160BY) is more than a decent alternative.

The 75400 PowerOpener combines 3 appliances in 1 package. It cuts bags with an in-built bag slitter, opens bottles with a bottle opener, and has a convenient cord storage.The only thing that could be added is a knife sharpener, but the fact is that most knife sharpeners that come in-built in smaller kitchen appliances don’t exactly have high quality standards.

The in-built sensor with automatic shut-off function automatically shuts the motor off when the can is opened which is a convenient feature that also makes it safer to use. The cutting lever is removable and can be washed in a dishwasher.

The downside of this device is the size of the power cord. It is quite short and if you want to replace it with a longer one, the warranty will be voided.


Electric vs, manual can opener differences?How long does an electric can opener last?
While a manual can opener can open any sized can, the main advantage of electric can opener is that it doesn’t require as much efforts to open a can. Electric can openers are especially helpful for older people and those with limited motor skills.
It depends on the quality of a device and the frequency of use. Some electric can openers can last a lifetime.


There are some people who don’t realize it, but the can is one of the most important innovations in the history of western civilization. It was invented two centuries ago and played a large role in helping western world powers to explore the globe. It has been a major player in the world’s prosperity and it’s used by billions of people all across the world.

Nutritious canned foods had a big role in extending life expectancy and health from 19th century on. Today consumers in the United States use over 130 billion cans per year and the can market is an eight billion dollar industry that employs almost 40 thousand employees. There are over 200 manufacturing plants in 38 states across the United States and there’s nothing that could replace a good old steel can anytime soon.

Although the can has come a long way since it was invented two centuries ago and has been always adapting, it is still a worthless piece of steel if you can’t open it and that’s where electric can openers come into play.
