Full Description:
FIELD OF THE INVENTION 
     The invention relates to a portable charger for charging cellular phones and other portable consumer electronic devices. 
     BACKGROUND OF THE INVENTION 
     Portable electronic devices require power to operate and are typically powered by rechargeable batteries. Due to cost and design concerns, those batteries are of limited capacity and may require frequent recharging, sometimes multiple times per day and in places where AC power is not available or easily accessible. 
     Existing portable batteries may have only female adapter ports that require separate charging cords with male connectors to connect to the portable electronic device to be charged. Separate charging cords are inconvenient because they can become tangled or lost, often because the cables do not have a consistent storage space when not in use. 
     Existing portable device chargers may have retractable charging cord reels built into the housing, but those chargers lack batteries, so must be plugged into an AC outlet to charge a device, which solves the problem that the cords create, but does not resolve the portability component. 
     SUMMARY OF THE INVENTION 
     A charger for charging electronic devices, including a top having a perforated portion and a housing, the housing including a rechargeable battery contained within the housing; one or more cables electrically coupled to the battery and at least partially contained within the housing; one or more cable retractors contained within the housing for retracting a substantial portion of the one or more cables inside the housing via openings on a bottom surface of the housing, where an end of the cable includes a charging head that is not retracted into the housing; a power port on the bottom surface of the housing coupled to the rechargeable battery, the power port electrically and mechanically coupleable to an external electrical power source; two or more legs extending from the housing supporting the charger on a surface; one or more windows arranged between the legs that extend only partially toward the surface such that the cables and charging head may pass through the space between the windows and the surface when the cables are in an extended state, the windows formed of a material that is at least semi-transparent such that the charging heads are visible through the windows when the cables are in a refracted state; wherein the top is removably mechanically coupled to the housing, thereby forming a storage area accommodating at least one three-foot charging cable and one three-foot external power connector, and wherein the perforated portion of the top allows heat to pass outward from battery.

In one aspect according to the present disclosure, Housing  2  may have Housing Window  3  attached to Housing Wall  15 . Housing Window  3  may be at least partially transparent, thereby allowing a user to locate Dual Tip Charging Heads  7  for access. Housing Window  3  may extend from the Housing  2  toward the surface, thereby advantageously protecting the electronic connectors on the bottom side of the charger, for example during inclement weather if the mobile charging device is to be used outdoors. 
       FIG. 2  shows a top view of Top  1 . In one aspect, the mobile charging device may be 5.00 inches in diameter and 6.45 inches tall. The mobile charging device may be manufactured from injection molded ABS plastic or metal, such as aluminum. 
       FIG. 3  shows the bottom view of mobile charging device according to an aspect of present disclosure. Under Carriage  5  attaches to Housing Wall  15  of Housing  2 . On the bottom face of Under Carriage  5  is LED Indicator  6 , which displays the charging status of the battery (not shown, described in more detail below) stored within Housing  2 . The LED Indicator  6  indicates the level of charge stored within battery and/or when the battery is charging. AC Adaptor Port  9  may accept a standard 100/240 Volt AC adaptor to charge the battery through a wall circuit. Under Carriage  5  also houses two Downstream USB Port  8  which allows the user to charge devices from the battery through the use of an USB cord. 
       FIG. 4  shows a perspective view from below of mobile charging device according to an aspect of present disclosure. Under Carriage  5  has four Cord Apertures  10 , which provide passage of Retractable Cord  11  from the retractable cord reel (not shown) stored within Housing  2 , so user may extend and retract Retractable Cord  11 . Attached to the end of Retractable Cord  11  is Dual Tip Charging Head  7 . 
       FIG. 5  shows a cross-sectional view of mobile charging device according to an aspect of present disclosure. In this view, Top  1  is removed from Housing  2 .
