Abstract

Consolidated power tips allow a power adaptor to be connected to disparately sized input ports of electronic devices. The consolidated power tips may be sized to balance insertion and pull-out forces for the disparately sized input ports. Deformable members may be added to the consolidated power tips for more desirable insertion and pull-out forces and improved electrical contact. The consolidated power tips may be combined into a multi-sleeve power tip. Each sleeve comprises a device interface for a different set of input ports. Unused sleeves may be retracted into the housing of the power tip. Manual or automatic extension mechanisms may be provided for extending the device interfaces from the housing. The multi-sleeve power tip allows users to interface with a large number of disparate devices without changing power tips.
