USB connector for walkie talkie batteries

## Abstract

Portable RF radio transceivers, commonly known as walkie talkies, are powered by common replaceable batteries. Mobile devices, including cell phones, are chargeable from the walkie talkies having power output ports. USB or mini USB ports on the walkie talkies are used for the power outputs to charge mobile devices while moving through locations without interrupting both types of the communication devices.

## Background
This application claims the benefit of U.S. Provisional Application No. 61/944,259 filed Feb. 25, 2014, which is hereby incorporated by reference in its entirety as if fully set forth herein.


BACKGROUND OF THE INVENTION
Today we rely heavily on mobile phones for various forms of every day communication. One common complaint in the mobile electronic device industry is inadequate battery life. New advanced features and applications are constantly being added to existing smartphones, coupled with the proliferation of higher definition images online and video streaming. Battery technology has not kept pace with the power-draining applications being added to smartphones.
One possible solution in the past was to carry a spare battery. However, it is likely that a spare battery would discharge over time. Moreover, with the widespread use of smartphones such as the Apple iPhone, there are many smartphones that do not have replaceable batteries.
Walkie talkies, which are two-way radio frequency transceivers, are used in entertainment sites, construction sites, businesses and warehouses. Workers carrying walkie talkies at those locations also have cell phones to be able to talk with off-site people. Fresh batteries are readily available at those locations for use in the walkie talkies. However, batteries in cell phones cannot be replaced, and it is necessary to connect cell phones to fixed electrical outlets for recharging. That takes the workers out of off-site communication capability while they move around the work location.
New cell phones and smartphones require recharging, typically using a wall charger or car charger, and cannot be supported by spare batteries. People on the move away from walls, automobiles, and trucks cannot easily use a power charger. One remedy for this problem was that separate portable power-packs were available. The disadvantage was that persons would have to carry the spare power-packs tethered to their phones. The portable power-packs are cumbersome and likely would discharge and lose power when most needed, such that the charged reservoir would not be available when needed.
Needs exist for new and less cumbersome mobile cell phone chargers.
SUMMARY OF THE INVENTION
The present invention addresses the general problem of charging a cell phone or other mobile device while being mobile. The teachings described herein generally relate to a power supply that can be used to carry, charge, and power a portable electronic device. In the movie industry, workers typically carry on their person walkie talkies that employ rechargeable batteries. Replacement batteries are always on site nearby.
The present invention provides walkie talkies with built in USB ports and/or mini-USB ports. The built in ports would be used to provide power to recharge a cell phone while the person carrying the equipment is on the move and is independently mobile. A walkie talkie with built in USB ports, mini-USB ports and/or external power ports would eliminate the need to carry separate devices designed solely for the purpose of acting as an emergency power backup.
Portable RF radio transceivers, commonly known as walkie talkies, are powered by common replaceable batteries. Cell phones and other mobile devices are chargeable from the walkie talkies having power output ports. USB or mini USB ports on the walkie talkies are used for the power outputs to charge mobile devices, including cell phones, while moving through locations without delay or interruption of communications through the portable RF transceivers and mobile devices.
Although the walkie talkie's own battery life would be drained as a result of charging a cell phone, access to fresh walkie talkie batteries is easy to come by. The walkie talkie batteries are replaced as need be from nearby supplies, allowing the user to continue to charge his or her mobile devices through a freshly charged walkie talkie while mobile and moving around.
The present invention provides a USB port and/or a mini-USB port located in the sides or within a bottom of the walkie talkie or anywhere on the walkie talkie. Using a USB cable or universal mini-USB cell phone charger or adapter, the user could hook up his or her mobile device to the walkie talkie while mobile. The present invention also comprises an adapter plate that fits between a walkie talkie and a battery. This adaptor plate contains a USB port and/or mini-USB port as well as a voltage regulator board that can be used on existing walkie talkies and their batteries.
A cell phone charger charges a mobile device providing power from a walkie talkie. A portable power supply is provided in the walkie talkie. A USB port is provided on the walkie talkie. A power connection runs from the power supply in the walkie talkie to the USB port. A mobile device charging power output in the power connection to the USB port charges a mobile device from the portable power supply in the walkie talkie.
The USB port is a mini USB port. Replaceable batteries are provided in the power supply of the walkie talkie. A power cord with a USB plug is provided on a first end and a mobile device connector is provided on a second end, connecting a USB plug to the USB port in the walkie talkie and connecting the mobile device connector to a mobile device for charging the cell phone.
A walkie talkie has a power supply within the walkie talkie. A power output on the walkie talkie is connected to the power supply. A first end of an electrical connector is connected to the power output, and a second end of the electrical connector is connected to a charging input of a mobile device for recharging a battery in the mobile device.
The invention uses a portable body having a two-way radio frequency transceiver in the portable body. A power supply in the portable body is connected to the radio transceiver. An output power jack on the body is connected to the power supply and is adapted to receive a connector to a mobile device for recharging a battery in a mobile device from the power supply of the portable transceiver. The power supply has replaceable batteries. The replaceable batteries are rechargeable or non-rechargeable batteries.
One mobile device is a cell phone and the power jack is a USB port. A mini USB port also could be mounted on the body and connected to the power supply.
An adapter plate adapted for affixing to the portable RF transceiver body has one or more output jacks. One output jack is a USB port.
A mini USB port is mounted on the adapter plate and connected to the power supply.
These and further and other objects and features of the invention are apparent in the disclosure, which includes the above and ongoing written specification, with the claims and the drawings.
