First Claim
Patent Images
1. An apparatus comprising:
- an enclosure including a processor and memory;
an internal charger to receive DC power from an external supply and provide charging current to charge a battery;
a battery connector to receive current from the internal charger and to provide current to the processor and memory; and
a fast charge connector to receive a fast charging current from a charger module and selectively couple the fast charging current to the battery connector.
