Multi-prong power tip adaptor
View Patent ↗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. For input ports with different electrical requirements, a mode selector may be added to the consolidated power tip to select between the electrical requirements of the different input ports. The consolidated power tips may be combined into a multi-prong power tip. The multi-prong power tip allows users to interface with a large number of disparate devices without changing power tips.
