breaking the first electrical connection between the first wireless adapter and the second wireless adapter;

removably coupling the first wireless adapter to the legacy device; and

wirelessly exchanging data between the legacy device and the host using the first wireless adapter, wherein the first wireless adapter is in a power save mode for a non-zero period of time when not wirelessly exchanging data.

14. A method as recited in claim 1 , wherein:

while the first wireless adapter is coupled to the second wireless adapter, the first wireless adapter is in a lower power state.

15. A system for charging including:

a first connector configured to form a first electrical connection directly between a first wireless adapter having a battery and a second wireless adapter without an intermediary device, wherein:

the first wireless adapter and the second wireless adapter are configured to provide wireless communications capability for a legacy device that does not have wireless communication capabilities and a host that does not have wireless communication capabilities by coupling, respectively, to the legacy device and the host and exchanging data on a wireless channel on behalf of the legacy device or the host to which the first wireless adapter or the second wireless adapter is respectively coupled during a data exchange mode; and

the first wireless adapter is configured to be able to be removably coupled to the legacy device to provide the wireless channel between the device and the host;

a second connector configured to form a second electrical connection directly between the second wireless adapter and the host without an intermediary device; and

a battery charger configured to charge the battery of the first wireless adapter via the second wireless adapter using the host.

16. A system as recited in claim 15 , wherein the battery charger is configured to charge the battery using Universal Serial Bus (USB).

17. A system as recited in claim 15 , wherein the battery charger is configured to charge the battery includes using ExpressCard.

18. A system as recited in claim 15 further comprising a processor configured to obtain an encryption key while the first wireless adapter and the second wireless adapter are removably coupled.

19. A computer program product for charging, the computer program product being embodied in a computer readable medium and comprising computer instruction for:

forming a first electrical connection directly between a first wireless adapter having a battery and a second wireless adapter without an intermediary device, wherein:

the first wireless adapter and the second wireless adapter are configured to provide wireless communications capability for a legacy device that does not have wireless communication capabilities and a host that does not have wireless communication capabilities by coupling, respectively, to the legacy device and the host and exchanging data on a wireless channel on behalf of the legacy device or the host to which the first wireless adapter or the second wireless adapter is respectively coupled during a data exchange mode; and

the first wireless adapter is configured to be able to be removably coupled to the legacy device to provide the wireless channel between the device and the host;

forming a second electrical connection directly between the second wireless adapter and the host without an intermediary device; and
