THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED

TECHNICAL FIELD
[0001] This present invention relates to a device for wirelessly charging electronic devices and, more specifically, to a device for providing a secure and stable platform for wirelessly charging electronic devices in vehicles.
BACKGROUND
[0002] Electronic devices are used throughout our daily lives for many things including communication, entertainment, and time management. Electronic devices are increasingly becoming more portable and more powerful allowing more users to do an increasing amount of activities remotely in the course of daily life. For example, many people now have smart phones which allow them to access e-mail, surf the web, and do other activities in addition to phone services. Other electronic devices commonly used include cameras, traditional cell phones, music players, and video players. Such devices are powered by batteries and require the user to continually monitor battery life and recharge batteries when needed.
[0003] Mobile devices like mobile phone, laptops, cameras and the like need regular charging of their batteries and it is a part of our daily lives. However, charging of the mobile devices through cables creates problems we all experience regularly. Mobile device users often settle by placing their charging cable throughout the house in a manner they would not allow for any other device. The cables don't really have a place where they belong. Instead, the cables rest on the floor, are stuffed between car seats, placed on our desks, and rest on nightstands. Additionally, people experience difficulty in connecting the charger cable in the correct orientation during the first attempt to plug it in or at night when the lights are off. Users often wake up reaching for their phone to see the time instead of simply looking at the time on their device without pressing any buttons or picking it up off the table. Users often experience problems associated with mounting a mobile device in a vehicle, home, or office. Users also find it awkward to hold the mobile device for several minutes in a single position while watching a video on their mobile device for the whole duration of the video.
SUMMARY
[0004] In view of the above, the present invention is directed to a device for providing power to a portable device, wherein the device includes a base housing having a circumferential outer extent configured to fit within a cup holder in a vehicle and a longitudinal axis and wherein the base housing includes a base, and a top housing having a top surface and a front lip and wherein the top surface is angled relative to the longitudinal axis between being parallel to the longitudinal axis and perpendicular to the longitudinal axis and wherein the top surface is closer to the base proximate to the front lip than the top surface is to the base remote from the front lip. The device further includes a primary charging unit including a charging circuit and a primary coil for inductively providing power.
[0005] In particular embodiments wireless chargers disclosed herein are programmable. By programmable it is meant that the wireless chargers can operate to wirelessly transmit power in accordance with one of a plurality of selectable protocols. In this manner, a power-transmitting protocol may be selected that is particularly suited for the electronic device being charged by the wireless charger.
