Description of the Related Art

Rechargeable batteries come in many types. Different batteries using different chemical materials require different methods of recharging. Current battery chargers are designed to be used for only one type of battery. For example, a lithium-ion battery requires a different battery charger than a nickel-cadmium battery. Each battery charger is configured only for one purpose, such as to maintain a constant voltage, a constant current, or a predetermined charging algorithm that may vary the voltage or current. More sophisticated battery chargers may use a charging algorithm to charge a battery quickly at first, then slow down the rate of charge as the battery nears full charge. By looking at prior art, various advancements have been seen providing charging cables and devices facilitating the above-mentioned requirements.

U.S. Pat. No. 4,006,396, issued in 1977, shows a universal charger for multiple types of batteries, with circuits for different charging rates. U.S. Pat. No. 5,828,966, issued in 1998, claims a reconfigurable cradle with interchangeable supports to charge different types of mobile phones which may have two or three connectors, and which may have the connectors at the top, bottom or sides. Duracell's 1997 U.S. Pat. No. 5,828,966 describes a universal charger with multiple male tabs for engaging a different number of female slots on different batteries. Palm, Inc.'s 2003 U.S. Pat. No. 6,614,206 describes a charger with multiple USB connections for providing charge to multiple devices.

U.S. Pat. No. 6,894,457 is directed to a charger with multiple cords for charging multiple portable devices. U.S. Pat. No. 5,157,319 shows an induction charger with a magnetic core surrounding the induction coil.

It also provides Motorola, Nextel, Nokia, Samsung, Sony Ericsson cell phone jack connectors. It allows charging a phone through any USB-powered port, with a 5-volt output.

Different devices to be charged use different charging profiles. The charging profile indicates the rate at which charges apply to the device in the form of current per unit of time, as well as the voltage at which the charge is applied. Some devices, such as cordless phones, portable CD players and similar consumer goods, use a slow charger, while other devices, such as cell phones, laptops, and camcorders, use a quick charger. For many devices, it is important to detect when the device is fully charged, so that the battery is not overcharged, thereby causing damage to the battery. Furthermore, each device can be different from other devices in terms of its receiving ports. Thus, one single universal cable providing charging for all types of smart devices is not seen in the prior art.

In short, there are multiple inventions that have been proposed in prior art. However, these solutions are limited and restricted to their conventional architecture and system. The proposed system provides a 6-in-1 universal charging cable with unique adapter mechanisms, combining USB-C, Lightning, and Micro-USB connectors in an ergonomic way.
