This portable, battery-powered opener is small enough to put in a drawer (or apron pocket), able to deal with any size can, and cordless for convenient use anywhere, around the kitchen orout camping.
It's simple to use — just secure it to the top of the can and hold the button down for a second. Automatically, it travels around and cuts a smooth edge just below the rim. For larger cans, press twice. When it stops, the lid lifts off safely and without any sharp edges.
Comment are, it looks like this is really to use and also it's small so you could really take it with when you are camping and having some canned food, so it's convenient too. You don't need much strength to open the can with the auto can opener.
