1. A power storage adapter (PSA), comprising:
- a first PSA port;
a PSA battery; and
a controller having access to memory media storing instructions executable by the controller to;
establish a first power delivery contract to supply a first electrical power from the power storage adapter to a first electronic device coupled to the power storage adapter at the first PSA port, wherein an alternating (AC) line power source and the PSA battery provide the first electrical power;
measure temperatures of the power storage adapter, including recording a first temperature at a first time and a second temperature at a second time after the first time;
determine a first rate of temperature change based on the first temperature, the second temperature, and a first time period given between the first time and the second time; and
when the second temperature exceeds a first temperature threshold and the first rate of temperature change exceeds a first rate threshold;
determine that the PSA battery has a battery capacity above a threshold; and
in response to determining that the PSA battery has a battery capacity above a threshold, supply a second electrical power to supply the first electronic device from the power storage adapter by reducing a portion of the first electrical power provided by the AC line power source such that a remaining portion of the second electrical power is provided by the PSA battery, the second electrical power less than the first electrical power.

Abstract
A power storage adapter may use a method for power delivery based on temperature and other factors. In particular, when electrical power is being supplied to a portable information handling system, a temperature of the power storage adapter may increase. Power storage adapter may reduce the electrical power being supplied to the portable information handling system based on the temperature to prevent the power storage adapter from potentially overheating.
