        abstract = {The increasing use of portable electronic devices such as smartphones, smartwatches, tablets, and wireless accessories has created a strong demand for efficient and portable charging systems. Conventional power banks require frequent charging from electrical outlets, which limits their usability in outdoor and emergency conditions. This paper presents the design and implementation of a Mini Solar Power Bank that utilizes renewable solar energy for charging electronic devices. The system consists of a 5V solar panel, TP4056 lithium battery charging module, 18650 lithium-ion battery, DC-DC boost converter, and USB output port. The solar panel converts sunlight into electrical energy, which is stored in the rechargeable battery through the charge controller. The boost converter increases the battery voltage to a stable 5V output suitable for charging USB-powered devices. The proposed system is compact, cost-effective, and environmentally friendly. Experimental testing shows stable output performance under sufficient sunlight conditions and reliable charging capability for small electronic devices. This project promotes the use of green energy solutions and provides an effective alternative to conventional charging systems.},
