Corded Power With Retractable Cord Storage
This is a plug-in appliance. Oster pairs it with retractable cord storage, so the lead pulls out when you need it and winds back into the base when you don't, which is the difference between a can opener that lives neatly on the counter and one that trails a cable across it. There is no battery to charge and nothing to run flat, so it is ready whenever it is plugged in. The trade-off is that it has to live within reach of an outlet. If you were hoping for a cordless opener to carry to a camper or a pantry shelf, this is not that product; if you want one that sits in one spot and works the same way every time, corded is the simpler choice.
