A power backup system for a coffeemaker comprising: an AC power source; a battery charger, where the battery charger receives power from the AC power source; a DC power source, where the DC power source remains charged by the battery charger; and a DC/AC inverter, where said inverter inverts the AC power to DC power upon activation of the power backup system and supplies power to the coffeemaker. The power backup system may further include a clock/timing device, where the clock/timing device sets a brewing sequence for the coffeemaker and receives power from AC power source, or if AC power is unavailable the DC power source. The power backup system may also include an automatic relay, where the automatic relay connects the DC/AC inverter to the timing device and other electrical components of the coffeemaker. |
