This invention includes a charger with at least two pockets capable of charging both a portable electronic device and a spare battery without charging circuitry in the charger. The invention includes takes advantage of an electronic device having charging circuitry disposed within, and also having external contacts for receiving an auxiliary battery. In a preferred embodiment, the invention couples the auxiliary contacts from a front pocket to battery contacts in the rear pocket. The connections are made directly with no charging circuitry in the series path. In so doing, when the portable electronic device and spare battery are placed in the charger, the portable electronic device's internal charging circuitry charges both batteries simultaneously.
