Information handling system external adapter and battery source
First Claim
1. A portable information handling system comprising:
- a housing;
a processor disposed in the housing and operable to execute instructions to process information;
a memory disposed in the housing and interfaced with the processor, the memory operable to store the information;
a display disposed in the housing and interfaced with the processor and memory, the display operable to present the information as visual images;
a power controller disposed in the housing and operable to accept external power and provide the external power to the processor, memory and display;
a port interfaced with the power controller and configured to accept a cable having power provided from an external power source; and
plural separate battery modules, each battery module operable to store power and having plural power ports, at least one power port removeably coupling with the information handling system port to discharge power and one power port removeably coupling with a charger device to accept charge power;
wherein the power controller is further operable to output external power to charge a first of the plural battery modules removeably coupled to the information handling system port at one of the plural power ports and having at least one additional of the plural battery modules removeably coupled to the other of the plural power ports; and
wherein each of the plural battery modules includes a charger operable to coordinate charging with power provided to one of the plural ports of an integrated battery and a removeably coupled battery module at another of the plural power ports.

Abstract
A portable information handling system battery module has a self-contained housing having a battery charger, integrated rechargeable batteries and plural ports to transfer power, such as USB Type C ports having bi-directional power transfer capability. A cable couples first battery module port to a portable information handling system port to provide power to the portable information handling system and accept power from the portable information handling system. Plural additional battery modules daisy chain to the first battery module to accept power from and provide power to the portable information handling system. Power transfer is coordinated with communications through the ports, such as by a USB power transfer protocol supported at the information handling system and each battery module.
