## Abstract

An apparatus includes a power-providing 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 internal battery is coupled to the power-providing connector port and configured to provide power via the power-providing connector port to the external device.

## Claims

### Claim 1

An apparatus comprising:
a power-providing 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; and
an internal battery coupled to the power-providing connector port and wherein the internal battery is configured to provide power via the power-providing connector port to the external device.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the power-providing connector port is a USB connector, a mini-USB connector, a micro-USB connector or a Lightning connector.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the internal battery is configured to be charged from an external power source while simultaneously providing power to the external device.

### Claim 4 (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 5 (depends on 1)

The apparatus of claim 1, further comprising:
an activator configured to move the power-providing connector port when a force is applied to the activator, wherein the activator is configured to extend the power-providing connector port beyond a housing and to retract the power-providing connector port into the housing.

### Claim 6 (depends on 1)

The apparatus of claim 1, further comprising:
a charging connector port; and
a bracket comprising the charging connector port at a first end of the bracket and the power-providing connector port at a second end of the bracket.

### Claim 7 (depends on 6)

The apparatus of claim 6, wherein:
the bracket further comprises a printed circuit board (PCB); and
the charging connector port and the power-providing connector port are mounted to the PCB.

### Claim 8 (depends on 7)

The apparatus of claim 7, wherein:
the PCB includes control circuitry that controls charging and discharging of the internal battery.

### Claim 9 (depends on 6)

The apparatus of claim 6, wherein the charging connector port is a USB connector, a mini-USB connector or a micro-USB connector.

### Claim 10 (depends on 6)

The apparatus of claim 6, wherein the charging connector port is configured to be connected to an external power source without the use of a cable therebetween.

### Claim 11 (depends on 6)

The apparatus of claim 6, wherein the internal battery is configured to be charged from an external power source via a cable coupled to the charging connector port.

### Claim 12 (depends on 6)

The apparatus of claim 6, wherein the charging connector port is configured to be coupled to a cable.

### Claim 13 (depends on 6)

The apparatus of claim 6, further comprising:
a housing; and
a cable with a first cable connector plug configured to be inserted through a first opening of the housing and into the housing and to be coupled to the charging connector port.

### Claim 14 (depends on 6)

The apparatus of claim 6, further comprising:
a housing;
wherein:
the housing has a first opening in a first surface of the housing and a second opening in a second surface of the housing;
the charging connector port is positioned at the first opening of the housing;
the power-providing connector port is positioned at the second opening of the housing; and
the first surface of the housing and the second surface of the housing are on opposite ends of the housing.

### Claim 15 (depends on 6)

The apparatus of claim 6, further comprising:
an activator configured to simultaneously move the charging connector port and the power-providing connector port, wherein the activator simultaneously extends the charging connector port beyond a housing and retracts the power-providing connector port into the housing, and the activator simultaneously extends the power-providing connector port beyond the housing and retracts the charging connector port into the housing.
