An electrical appliance (20) that accepts multiple different self-contained power sources (24, 33). As an example, an electrical appliance may receive a rechargeable battery pack (24) or a power cartridge (33) that is designed to receive disposable batteries (40). If the user does not have sufficient power left in a battery pack (24), the power cartridge (33) may be filled with disposable dry cell batteries (40), and may be inserted in the electrical appliance (20) to provide power. Another self contained power cartridge (44) may include a fuel cell. The fuel cell power cartridge (44) may include removable fuel cell cartridges (48), for example, each having a fuel therein, such as hydrogen.
