Abstract: A universal purpose power adapter has a first box and a second box, in which the first box includes a first socket, a first plug and first terminal blocks, and the second box further comprises a second plug and second terminal blocks. The second plug couples to the first socket and to the power output port at the same time; the first plug couples to the charging port of the backup battery. A backup battery can be connected to a digital product via the power adaptor. A selector circuit in each of the first and second boxes, and coupled, facilitates power routing through the connected boxes.

Abstract: A universal wireless adapter, which includes a power source, a power management element, a main processing unit, at least two serial connections, a wireless transceiver coupled to one of the at least two serial connections, wherein the transceiver is operable according to IEEE Standards 802.11b/g/n, and is capable of operating in one of an infrastructure mode and an ad hoc mode. The adapter also includes a volatile memory chip and a single non-volatile memory chip. The adapter also includes a synchronous boost voltage converter, wherein the input voltage from the battery is boosted to a higher, second voltage output. The second of at least two serial connections is a Universal Serial Bus (USB) serial connection; and a display coupled to the main processing unit, and the power source is a 2600 mAh, 3.7 volt battery. Mass-storage device couples to adapter to provide wireless access thereto.
