The application of the present application is hereby incorporated by reference in its entirety in its entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire content .

The present invention is generally directed to the field of power adapters that are provided for portable, battery powered consumer electronics.

There are currently many different portable, battery-powered consumer electronics products. Examples include mobile phones, digital cameras, laptops and MP3 players. Typical of these products are assembled with rechargeable batteries. However, in other examples, the product is assembled to receive a disposable battery.

Most of this product provides DC power input, whether or not it is packaged with an external power adapter. If so, the DC power input is configured to receive the appropriate DC voltage to charge and power the rechargeable battery.

It is well known to configure a power adapter that supplies DC power to the device. A typical example includes an AC/DC adapter configured to be plugged into a shared household outlet, receive home AC power, convert it to a suitable DC voltage to the device, and supply the converted power to the DC device. Other examples include being switched to receive a 12 volt power source from a car outlet (cigarette lighter), converting it to a suitable DC voltage to the device, and supplying the converted power source to the device's DC/DC adapter.

Indeed, many of the latest devices including rechargeable batteries are equipped with at least one AC/DC adapter. Thus, when the battery power is low and the outlet is available, the device can be easily powered and charged simply by plugging the adapter into the outlet and connecting it to the device.

Unfortunately, it is not always available to outlets, homes or other, and other power sources. Various portable power modules (PPMs) have been introduced to solve this problem. The portable power module is essentially a backup battery that is designed to couple with the DC input of a DC power supply such as a mobile phone and is discharged to provide the appropriate voltage.

The battery in the portable power module receives its power in various ways. Some are configured to receive a battery that can be used arbitrarily and convert its power to an appropriate voltage. Other portable power modules include a rechargeable battery and are configured to receive DC power via input from one of those found in conventional DC powered devices. Since a portable power supply module of a given DC power supply unit is typically purchased in the market for repairing repair parts, a typical arrangement is that the portable power supply module is configured to receive power from an AC/DC adapter of the device. Charging batteries.

Unfortunately, this design forces the user of a given DC power supply for the handset to carry its AC/DC adapter and a suitable portable power module to ensure that excess power is available in each case. Furthermore, in order to charge the mobile phone and the portable power module battery, the user must exchange the AC/DC adapter output between the two.
