The first end and the second end are opposite one another. An activator is configured to simultaneously move the first connector port and the second connector port when a force is applied. When the first connector port is extended beyond the housing, the second connector port is retracted into the housing, and when the second connector port is extended beyond the housing, the first connector port is retracted into the housing. An internal battery is coupled to the first connector port and configured to be charged via the first connector port from an external power source, and coupled to the second connector port and configured to provide power via the second connector port to an external device. ## Claims ### Claim 1 An apparatus comprising: a housing having a first opening in a first surface of the housing and a second opening in a second surface of the housing; a first connector port positioned at the first opening of the housing and within the housing; a second connector port positioned at the second opening of the housing and outside the housing and configured to be directly coupled to an external device without an intervening cable or an adapter connected between the apparatus and the external device; and an internal battery coupled to (i) the first connector port and configured to be charged via the first connector port from an external power source and (ii) the second connector port and configured to provide power via the second connector port to the external device. ### Claim 2 (depends on 1) The apparatus of claim 1, further comprising: a bracket comprising the first connector port at a first end of the bracket and the second connector port at a second end of the bracket. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein: the bracket further comprises a printed circuit board (PCB); and the first and second connector ports are mounted to the PCB. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein: the PCB includes control circuitry that controls charging and discharging of the internal battery. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the first connector port is a USB connector, a mini-USB connector or a micro-USB connector. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the second connector port is a USB connector, a mini-USB connector, a micro-USB connector or a Lightning connector. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the first connector port is configured to be connected to the external power source without the use of a cable therebetween. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the internal battery is configured to be charged from the external power source via a cable coupled to the first connector port. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the first connector port is configured to be coupled to a cable. ### Claim 10 (depends on 1) The apparatus of claim 1, further comprising: a cable with a first cable connector plug configured to be inserted through the first opening and into the housing and to be coupled to the first connector port. ### Claim 11 (depends on 1) The apparatus of claim 1, wherein the internal battery is configured to be charged from the external power source while simultaneously providing power to the external device. ### Claim 12 (depends on 1) The apparatus of claim 1, further comprising: circuitry coupled to the internal battery enabling the internal battery to be charged while simultaneously providing power to the external device. ### Claim 13 (depends on 1) The apparatus of claim 1, wherein: the first surface of the housing and the second surface of the housing are on opposite ends of the housing. ### Claim 14 (depends on 1) The apparatus of claim 1, further comprising: an activator configured to simultaneously move the first connector port and the second connector port when a force is applied to the activator, wherein the activator simultaneously extends the first connector port beyond the housing and retracts the second connector port into the housing, and the activator simultaneously extends the second connector port beyond the housing and retracts the first connector port into the housing. ### Claim 15 An apparatus comprising: a housing having a first opening in a first surface of the housing and a second opening in a second surface of the housing; a first connector port positioned at the first opening of the housing; a second connector port positioned at the second opening of the housing, the second connector port configured to be extended beyond the housing and retracted into the housing through the second opening of the housing, and the second connector port configured to be directly coupled to an external device without an intervening cable or an adapter connected between the apparatus and the external device; an activator configured to move the the second connector port when a force is applied to the activator; and an internal battery coupled to (i) the first connector port and configured to be charged via the first connector port from an external power source and (ii) the second connector port and configured to provide power via the second connector port to the external device. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein the first connector port is configured to be connected to the external power source without the use of a cable therebetween. ### Claim 17 (depends on 15) The apparatus of claim 15, wherein the internal battery is configured to be charged from the external power source via a cable coupled to the first connector port. ### Claim 18 (depends on 15) The apparatus of claim 15, wherein the internal battery is configured to be charged from the external power source while simultaneously providing power to the external device. ### Claim 19 (depends on 15) The apparatus of claim 15, further comprising: circuitry coupled to the internal battery enabling the internal battery to be charged while simultaneously providing power to the external device. ### Claim 20 (depends on 15) The apparatus of claim 15, wherein: the first surface of the housing and the second surface of the housing are on opposite ends of the housing.
