Most conventional blenders are made up of a power cord, blender jar, blender base, and a blender blade driven by a motor shaft. A typical blender should have a speed controller and a long enough appliance cord to reach most areas of your kitchen.

Warranties are sometimes voided by unauthorized repair, so make sure your warranty isn’t expired before picking up your tools. The warranty process usually requires a copy of the receipt, but some brands require the original packaging as well.
