Adjusting current based on temperature. A change in temperature of a connection between a first device and a second device may be measured. The change in temperature may be performed while the first device provides current to the second device over the connection. If the change in temperature is above a threshold, the current being provided from the first device to the second device may be reduced. The change in temperature may be performed by the first device and/or the second device, e.g., by measuring the temperature of a connector of the connection.
