Which is easier to set up, the Kitchen Mama or the Black+Decker Spacemaker?

The Kitchen Mama Auto, by a wide margin. It needs only 4 AA batteries and works immediately, no tools or mounting required. The Black+Decker Spacemaker EC600 requires a one-time under-cabinet installation with a screwdriver or drill, typically taking 15 to 20 minutes.

Which has more motor power, the Kitchen Mama or the Black+Decker Spacemaker?

The Black+Decker Spacemaker EC600, since it's a corded design rather than battery-driven. This shows up most on large or dented cans, where the Kitchen Mama's battery-powered motor is more likely to need a second pass or occasionally stall, while the corded Spacemaker maintains more consistent torque.

Which is better for a small kitchen with limited space?

Both solve the space problem, just differently. The Kitchen Mama is compact and cordless, so it can live in a drawer and never take up counter space at all. The Black+Decker Spacemaker mounts under an existing cabinet, freeing both counter and drawer space, but only if there's suitable cabinet clearance to mount it in the first place.

Which one should I buy if I'm not sure?

Choose the Kitchen Mama Auto if you want the simplest possible setup and cordless flexibility, and don't want to deal with installation. Choose the Black+Decker Spacemaker EC600 if you're willing to install it once in exchange for a permanently mounted unit with stronger corded torque and no batteries to manage.

Kitchen Mama Auto vs Black+Decker Spacemaker EC600: Which Electric Can Opener Should You Buy?

The Kitchen Mama Auto (cordless, one-button, magnetic lid lift) and Black+Decker Spacemaker EC600 (under-cabinet mount, corded, permanently frees counter space) take opposite approaches to convenience. This comparison covers setup, daily use, and who should buy each.

The Kitchen Mama Auto and the Black+Decker Spacemaker EC600 solve the same problem, an appliance you don't want cluttering the kitchen, in nearly opposite ways.

One goes cordless and compact enough to disappear into a drawer. The other mounts permanently under a cabinet so it's never on the counter or in a drawer at all.

Neither is objectively better; the right choice depends on whether you'd rather avoid installation entirely or avoid battery management entirely.

Setup and Installation

The Kitchen Mama needs nothing beyond inserting batteries. The Black+Decker Spacemaker requires mounting a bracket under a cabinet first, a 15 to 20-minute one-time task with a screwdriver or drill. For anyone who wants to use a can opener the moment it arrives, the Kitchen Mama has a clear advantage here.

Motor Power and Large Cans

The corded Black+Decker Spacemaker maintains more consistent torque through a cutting cycle, particularly noticeable on large or dented cans where the Kitchen Mama's battery-driven motor sometimes needs a second pass. For routine large-can use, the Spacemaker is the steadier performer.

Everyday Convenience

The Kitchen Mama's magnetic lid lift is a genuine safety and convenience feature the Spacemaker doesn't include, removing the need to pinch a sharp cut lid off by hand. The Spacemaker's advantage is that, once mounted, there's truly nothing to store, charge, or replace batteries for.

Price and Value

The Kitchen Mama costs $10 to $20 less and carries by far the larger review base, a strong reliability signal. The Spacemaker's higher price reflects the mounting hardware and fixed installation rather than a fundamentally different cutting mechanism.

Which Should You Buy?

Choose the Kitchen Mama Auto if: you want zero installation, cordless portability, and a magnetic lid lift, and you mostly deal with standard-size cans.

Choose the Black+Decker Spacemaker EC600 if: you're willing to install it once in exchange for permanently freed counter space, stronger corded torque, and no batteries to manage.
