What is a four-slice toaster?

A four-slice toaster is a toaster that can toast up to four slices of bread in a single cooking cycle. This type of toaster can come in a traditional toaster design or set in an oven-style setting.

An oven-style toaster generally has two control knobs, which allow the user to change both cooking time and toasting temperature independently. This design places all four slices of toast under the same toasting variable. Classic toaster designs can have batch controls where the four slices of bread are divided into two separate batches. Each batch can be toasted independently and the breads are set on lifts which moves the bread up when it has finished toasting.
