This paper introduces the conceptual design of a universal smart charger that addresses limitations of existing charging systems. The proposed solution employs a U-shaped pogo pin–based dock that removes the need for charging cables, integrates adjustable side arms for compatibility with multiple devices, and applies smart watt-detection to deliver only the required power. To expand functionality, the design also incorporates a USB-A/USB-C port capable of adaptive power delivery for laptops and other devices, along with a wireless charging pad for accessories such as earbuds and smartwatches. Safety features include automatic cut-off at 95% state-of-charge (SoC), overload protection, and thermal monitoring, making the system suitable for public charging stations. Although the work is conceptual and does not yet include a prototype, the proposed design demonstrates significant potential to enhance charging safety, efficiency, and multi-device adaptability in public and private environments.
