PORTABLE POWER CHARGER WITH REMOVABLE RECHARGEABLE INTERNAL BATTERIES

摘要

A portable charger unit includes a tray defining a plurality of cavities for receiving removable batteries; a head attached to the tray; a power input port in the head; a power output port in the head; and charging circuitry within the head that interconnects the input port, the output port, and the cavities of the tray. In a first mode of operation the charging circuitry receives input voltage and current from the power input port and delivers internal battery voltage and current to the cavities of the tray, and in a second mode of operation the charging circuitry receives internal battery voltage and current from the cavities of the tray and delivers output voltage and current to the power output port.
