Abstract

Disclosed is a method to provide wired connections to the battery terminals for any electronic device that is not currently capable of being powered by an AC-to-DC converter or for one where the external power source has been misplaced or lost. The wired connector would then be powered by an AC-to-DC converter so that batteries would not be needed to power the device. This one unit would be able to power many devices and not be specific to one. The wires would simply connect to the battery terminals and would therefore be truly a universal power source.

Disclosed is a universal power supply that would be programmable to work with any device. Many battery operated electronic devices do not have an AC adapter or input to allow the device to be powered using anything other than batteries. This causes unnecessary waste in batteries that usually end up leaking in landfills. Rechargeable batteries are expensive, take time to recharge, eventually wear out, and need to be recycled. The power adapter may have been lost or damaged. The recharging base could have been replaced or its power source lost. The user would have to continually purchase or recharge batteries. Universal adapters exist, but may not have the type of plug that is needed, give you too many adapters to lose, or your device may not have an DC port.

Current universal power supplies have a set voltage and current and can only be used on specific devices with specific input ports. Figure 2 shows an example of a universal power supply available today. It comes with specific connectors that must be available on the battery powered device. Many devices today are battery powered only and do not have the option for a plug in power source. Note also that the voltage is constant. The user cannot specify how much power the battery operated device needs. If the user chooses the wrong plug, it could potentially render the battery operated device inoperable.

power source would allow for wired connections to the battery terminals and allow the user to specify how much power is necessary for the particular device. This universal power source would allow the user to change the amount of power needed so that it could be easily used for any device.

This universal power source would have user defined inputs. The user would enter the type (i.e.
