Power systems for touch free dispensers and refill units containing a power source

An electronic dispenser comprising:

• a housing;
• actuator drive circuitry for driving a pump;
• a processor;
• a first power source for powering the processor;
• a plurality of capacitors;
• capacitor control circuitry for charging the plurality of capacitors in parallel and
• for placing the plurality of capacitors in series to power the actuator charge circuitry;
• and
• circuitry for electrically coupling to a second battery that is secured to and removable with a refill unit,
• wherein the second battery supplies the power to charge the plurality of capacitors.

An electronic dispenser comprising:

• a housing configured to receive a refill unit, the refill unit having
• a container for holding a fluid,
• a pump for pumping fluid from the container, and
• a disposable battery provided with the refill unit;
• and
• an electrically operated actuator to operate the pump of the refill unit,
• wherein the disposable battery of the refill unit has an initial voltage that is less than the voltage required to operate the electrically operated actuator.
