Abstract
An energy storage device, like for example a supercapacitor, is used to provide power to activate a motor for dispensing a dosed amount of hand care product. The energy storage device or supercapacitor is recharged from an energy supply source, e.g. batteries, integrated into the replaceable refill reservoir and/or mounted into the dispenser housing. A controller directs energy discharged from the energy supply source(s) at one of a plurality of discharge energy rates for recharging the energy storage device. Depending on the number of dispense events that occur with a given time interval, the controller may vary the rate at which the energy is discharged from the energy supply source(s) to recharge the energy storage device.
