BACKGROUND
Field of Invention
[001] Embodiments of the present invention generally relate to a charger and particularly to a portable solar-powered wireless charging system.
Description of Related Art
[002] Electronic devices require a continuous and reliable source of power to operate effectively in both indoor and outdoor environments. Traditional grid-dependent charging solutions limit mobility and fail to meet power demands in off-grid or emergency scenarios. Consumers often rely on power banks, which store energy for portable use, yet these too depend on prior grid-based charging and remain ineffective in areas without access to electricity. The need for a self-sufficient, environmentally sustainable energy source continues to remain unmet by many commercially available products.
[003] Solar-powered chargers have entered the market as an alternative to conventional methods, offering a renewable and cleaner energy option. However, these chargers often suffer from poor energy conversion efficiency, especially under variable sunlight conditions. Slow energy transfer, reduced charging speeds, and environmental factors such as shade or cloud cover restrict their practical utility. Additionally, these solar solutions typically employ basic energy storage units with limited capacity and no integrated power regulation features to ensure safe and optimal energy transfer.
[004] A further challenge with existing wireless and solar charging solutions lies in their inability to control thermal build-up. Excessive heat produced by solar panels and wireless charging coils can damage sensitive electronic circuits and batteries. Many commercial products do not contain thermal insulation, cooling systems, or adaptive energy management, which results in rapid degradation of components and inefficient charging cycles.
[005] There is thus a need for an improved and advanced portable solar-powered wireless charging system that can address the aforementioned limitations in a more efficient manner.
