Innovation Solution
A wallet-sized portable power charger kit with a rechargeable battery unit, multiple interchangeable charging cables, and dual function power ports for both input and output, allowing for easy charging of various devices in compact form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard external power source is used for charging, then charging reliability is improved, but portability deteriorates as the device must remain tethered to the power source
Solution Approach 1:
The charging system is segmented into a stationary power source component and a portable charger component. The portable charger contains an internal battery that can be recharged from external sources, separating the bulk power storage from the charging location, enabling portability while maintaining charging reliability through the rechargeable battery mechanism
Solution Approach 2:
The portable charger acts as an intermediary energy storage device between external power sources and electronic devices. It receives power from various external sources (wall outlets, car chargers, computers) and stores it in its internal battery, then provides power to devices independently, mediating between fixed power infrastructure and mobile device needs
2Adaptability or versatility
If multiple charging cables are used for different devices and power sources, then adaptability is improved, but device complexity increases
Solution Approach 1:
The portable charger is designed with universal USB connection ports that can charge multiple types of electronic devices (smartphones, tablets, cameras, music players) through a single interface. The standard USB port serves multiple functions: charging from computers, wall adapters, and car chargers, as well as providing power to various devices, eliminating the need for device-specific charging cables
Solution Approach 2:
Multiple charging functions are merged into a single portable charger unit with a universal USB interface. Instead of having separate charging solutions for different devices and power sources, the invention combines all charging capabilities into one device that can both receive power from and provide power to various electronic devices through the same connection port

AI summary
A portable power charger kit is provided for charging electronic devices from a rechargeable internal battery. The portable charger kit comprises a wallet, a charger unit, and one or more interchangeable charging cables, each having a first end connection interface and a second end connection interface. The ends of the charging cable are storable within respective first and second cavities formed in the charger unit. A power connection port is provided in the charger unit in operative communication with the internal battery. The connection port may be disposed within the first cavity for engagement with the first connection interface of the charging cable. The second end of the charging cable may be removed from its storage cavity and flexed out and away from the charger housing for engagement with a portable electronic device or an external power source while the first end remains in engagement with the power connection port.
