1. An uninterruptible power supply (UPS) for supplying an uninterruptible direct-current power to an electric appliance having a housing frame, the UPS receiving alternating-current (AC) power from an AC outlet, the UPS comprising:
- a transformer circuit for converting the AC power to a main source of DC power;
a battery for supplying a back-up source of DC power;
a switching circuit for electrically coupling the battery with the transformer circuit;
a housing physically supporting the switching circuit, the battery, and the transformer circuit, the housing being separate and apart from the housing frame; and
a connector attached to the housing for attaching the UPS to the AC outlet.

Abstract
An uninterruptible power supply (UPS) (100) has a housing (111) that supports the major electrical components of the UPS (100), i.e., a transformer circuit (207), a switching circuit (217), and a battery (209). Furthermore, a connector (107;115;117) affixed to the housing (111 ) is capable of removably affixing the UPS (100) to an alternating-current (AC) outlet (102).
