    Abstract: A rechargeable charger that includes a rechargeable battery and charging control circuitry for controlling a charging of at least one portable rechargeable device. The charging control circuitry is configured such that charging is automatically and periodically interrupted after reaching a charged state. During a charging phase energy is transferred from the rechargeable battery to the portable rechargeable device via interface circuitry until gauging circuitry indicates that a threshold value has been reached upon which a pause phase is entered where charging of the portable rechargeable device from the rechargeable battery is suspended. In the pause phase a timer is started, and when the timer has elapsed, the charging phase is started again. As a result, phases of charging the portable rechargeable device and phases of switching off the charging alternate.
