Electric can openers are actually a very old design. The first electrically operated can opener was patented in 1931 but failed because they were too complicated in design. Until 1956, there were no electrically powered can openers to speak of until Udico brought a simple free standing device that was a combination can opener and knife sharpener that became a hit immediately.
All electric can openers operate on the same principle, and that is based on the more than a century old bunker tin opener design. The simplest of them are nothing but an electrical version of the mechanical bunker design. There is a gripping lever that grips the can in place, along with a cutting wheel. This wheel is connected by gears so that it can rotate, cutting the can as it does so and the same gears also work with the gripping mechanism to rotate the can about its axis.

The usual way that the electric can openers work is by keeping the can in place and depressing the lever that is found in front. This lever is connected to a switch so that when it is depressed, the machine comes on. The tin openers are actually very fast and can open more than 20 cans per minute in even the simplest of designs.
There are a number of versions that you can choose from with prices starting from to more than . There is not much difference between the cheap and more expensive ones in the way they work or their efficiency levels. The only difference is in the brand and the finish. The plastic can openers are cheaper than the stainless steel ones, and the taller ones that are capable of opening bigger tins are more expensive than the smaller ones.
The simple hand held openers are more mid range because they are battery operated. These can openers are probably the best of the lot because you just fix them on the jar and push one button, and the job is done. You can use them for tins of any size and they work equally well with all of them.
If however you are just looking for a good value for money can opener then you'll be hard pressed to go past the standard hand held manual openers. They are cheap, quick and do the job well. At the end of the day the choice is up to you!
