Abstract
A host device such as a camera, PDA, etc. can have an attachment such as a wireless modem, with both host and attachment having respective batteries. Some loads in the host are always powered by the host battery, and some loads in the attachment are always powered by the attachment battery, but some other loads in the attachment are selectively powered by either the host or attachment battery depending on a power consumption and/or the relationship between the charges remaining in the batteries.
