A motorized shopping cart is a shopping cart equipped with an electric motor and navigational controls. It includes a seat thereby also making it a motorized wheelchair, and it has a rechargeable battery that can be charged by plugging in the device when not in use in order to maximize usage. Motorized shopping carts are provided by supermarkets and other large retail stores for those with permanent or temporary physical disabilities who may have difficulty walking through a large store or pushing a regular cart.

A motorized wheelchair, powerchair, electric wheelchair or electric-powered wheelchair (EPW) is a wheelchair that is propelled by means of an electric motor rather than manual power. Motorized wheelchairs are useful for those unable to propel a manual wheelchair or who may need to use a wheelchair for distances or over terrain which would be fatiguing in a manual wheelchair. They may also be used not just by people with 'traditional' mobility impairments, but also by people with cardiovascular and fatigue-based conditions.
