`ABSTRACT
`A switchable direct current voltage power supply for pow
`ering a device having an uninterruptible power supply with
`additional standby power capacity where the switching
`power supply has a power input and a power output for
`powering a device with a first battery pack attachable to the
`switching power supply for providing power to the device
`when the power input fails and a second battery pack
`attachable to the first power supply providing additional
`standby power capacity and where the attachable battery
`pack utilizes lithium chemistry .

`Description of the Related Art :
`BACKGROUND OF THE INVENTION :
`Traditional products include installation of CPE device
`with or without the device housing and offers no universal
`The present invention is a portable switching direct cur
`rent voltage power supply used at least in the telecommu- 20 movement unspecific to the individually manufactured CPE
`nications industry where low - voltage direct current devices
`device .
`require a switching power supply to step down the voltage
`from a standard one hundred ten ( 110 ) volt alternating
`SUMMARY OF THE INVENTION :
`current , or other voltage source , to 12 volt direct - current , or
`A portable switching Vdc power supply is provided with
`other desired step down voltage . Additionally these devices 25
`attachable Li Ion battery pack ( s ) designed for powering and
`use uninterruptible power backup systems so that in the
`providing “ scalable ” levels of standby battery backup to
`event of a power failure they continue to operate in order to
`Customer Premises Equipment ( CPE ) devices . The switch
`provide continued telecommunication services or other ser
`vices from the respective devices to the public .
`ing Vdc power supply can operate as a stand - alone power
`30 supply to any accepting 12Vdc Customer Premises Equip
`Field Of The Invention :
`ment device and also operate as a “ Uninterruptable Power
`The present invention is directed to offer new efficiencies
`Supply ” ( UPS ) when partnering Li Ion battery pack ( s ) are
`in the field of telecommunications for size , scalabilty and
`connected and operational . The switching Vdc power supply
`functionality , by allowing an end user the capability to
`with attachable Li Ion battery pack ( s ) is designed to offer the
`install anywhere within the premises , as a wall mount ,
`desktop mount or floor mount , as well as allow for a 35 world's smallest portable telecommunications Uninterrupt
`stand - alone power supply or scalable uninterruptable power
`able Power Supply and the world's only solution to allow the
`supply with optional stackable Li Ion ( lithium ion ) battery
`customer the ability to add additional , “ stackable ” Li Ion
`packs for customized battery backup availability .
`battery packs for additional standby power capacity as
`The provided solution is the first to integrate a network
`required per installation . Together with one or multiple Li
`solution to both provide a universal housing for a telecom- 40 Ion battery packs , the switching Vdc power supply offers the
`munication's Customer Premises Equipment ( CPE ) device
`only solution to utlilize stackable battery packs utilizing
`and also incorporate a switching Vdc ( direct current voltage )
`Lithium Chemistry . The switching Vdc power supply with
`power supply with optional battery packs utilizing lithium
