Modern electronic appliances are becoming ubiquitous for personal as well as business use. It cannot be overstated that with the evolution of such devices, mobility has emerged as a key driver in feature enhancement for technological innovation.
While the rapid advancement of low power-consumption processors and flash-memory devices has enabled such mobility to reach new levels of real-world productivity, further development is significantly hampered by the rather slow progress made in battery technology. The proliferation of smart phones, tablets, laptops, ultrabooks, and the like (acquiring smaller and smaller form factors) has made this issue even more abundantly apparent as consumers are eager to have longer and longer device usage times between recharge cycles, without adding heft to the weight and footprint of such devices.
The present invention discloses devices, for adaptive fast-charging of mobile devices, including:
a charge-delivering device for providing electrical power to a charge-receiving device;
and at least one electrical-contact pin for enabling electrical current to be transmitted at an amperage greater than about 5 A to the charge-receiving device.
Preferably, the charge-receiving device is selected from the group consisting of: an integral power-source component of a mobile device and a slave battery.
Preferably, at least one electrical-contact pin is further configured to transmit the electrical current at an amperage selected from the group consisting of: greater than about 10 A, greater than about 20 A, greater than about 30 A, and greater than about 60 A. Preferably, at least one electrical-contact pin is spring-loaded. Preferably, at least one electrical-contact pin includes protection circuitry for protecting against thermal overloads and short circuits. Preferably, the device charger further includes: a receiving-area holder for properly engaging the charge-receiving device.
