outputting, by the first computing device and for display, a notification indicating whether the second computing device is operatively coupled to the power source.

5. The method of claim 1 , further comprising:

receiving, by the first computing device, an indication that the second computing device should receive notifications from the first computing device if the second computing is operatively coupled to the power source; and

responsive to receiving the indication, sending, by the first computing device, to the second computing device, an indication of the notification when the second computing device is operatively coupled to the power source.

6. The method of claim 1 , further comprising:

receiving, by the first computing device, an indication of a notification type; and

responsive to determining that the notification is of the notification type:

outputting, by the first computing device and for display, the notification; and

sending, by the first computing device, to the second computing device, the indication of the notification.

7. The method of claim 1 , further comprising:

determining, by the first computing device, a time of day;

wherein outputting the notification and for display comprises outputting, by the first computing device, for display, and based on the determined time of day, the notification,

wherein sending the indication of the notification to the second computing device comprises sending, by the first computing device, to the second computing device, and based on the determined time of day, the indication of the notification.

8. A first computing device comprising:

one or more processors; and

a charging module operable by the one or more processors to:

responsive to determining that a second computing device is operatively coupled to a power source, output by the first computing device and for display, a notification; and

responsive to determining that the second computing device is disconnected from the power source, send, by the first computing device, to the second computing device, an indication of the notification.

9. The first computing device of claim 8 , wherein the charging module is further operable to:

receive, by the first computing device, from the second computing device, a message indicating a charging state of the second computing; and

determine, by the first computing device, based on the message, whether the second computing device is operatively coupled to the power source.

10. The first computing device of claim 9 , wherein the message includes an identifier that identifies the second computing device.

11. The first computing device of claim 8 , wherein the charging module is further operable to:

output, by the first computing device and for display, a notification indicating a charging state of the second computing device.

12. The first computing device of claim 8 , wherein the charging module is further operable to:

receive, by the first computing device, an indication that the second computing device should receive notifications from the first computing device if the second computing is operatively coupled to the power source; and

responsive to receiving the indication, send, by the first computing device, to the second computing device, an indication of the notification when the second computing device is operatively coupled to the power source.

13. The first computing device of claim 8 , wherein the charging module is further operable to:

receive, by the first computing device, an indication of a notification type; and

responsive to determining that the notification is of the notification type:

output, by the first computing device and for display, the notification; and

sending, by the first computing device, to the second computing device, the indication of the notification.

14. The first computing device of claim 8 , wherein the charging module is further operable to:

determine a time of day,

wherein to output the notification and for display, the charging module is further operable to output, by the first computing device and for display, the notification based on the determined time of day,

wherein to send the indication of the notification to the second computing device, the charging module is further operable to send, by the first computing device, to the second computing device, the indication of the notification based on the determined time of day.

15. A non-transitory computer-readable storage device storing instructions that, when executed, cause at least one processor of a first computing device to:

responsive to determining, by a first computing device, a second computing device is operatively coupled to a power source, output, by the first computing device and for display, a notification; and

responsive to determining that the second computing device is disconnected from the power source, send, by the first computing device, to the second computing device, an indication of the notification.

16. The non-transitory computer-readable storage medium of claim 15 , further comprising instructions that, when executed, cause the at least one processor of the first computing device to:

receive, by the first computing device, from the second computing device, a message indicating a charging state of the second computing; and

determine, by the first computing device, based on the message, whether the second computing device is operatively coupled to any power source.

17. The non-transitory computer-readable storage medium of claim 16 wherein the message includes an identifier that identifies the second computing device.

18. The non-transitory computer-readable storage medium of claim 16 , further comprising instructions that, when executed, cause the at least one processor of the first computing device to:

output, by the second computing device and for display, the indication of the notification.

19. The non-transitory computer-readable storage medium of claim 15 , further comprising instructions that, when executed, cause the at least one processor of the first computing device to:

receive, by the first computing device, an indication that the second computing device should receive notifications from the first computing device if the second computing is operatively coupled to the power source; and

responsive to receiving the indication, send, by the first computing device, to the second computing device, an indication of the notification when the second computing device is operatively coupled to the power source.

20. The non-transitory computer-readable storage medium of claim 15 , further comprising instructions that, when executed, cause the at least one processor of the first computing device to:

receive, by the first computing device, an indication of a notification type; and

responsive to determining that a type of the notification has a same type as the notification type:

output, by the first computing device and for display, the notification; and

sending, by the first computing device, to the second computing device, the indication of the notification.
