Why does wireless power bank need active cooling?, wireless cooling

Wireless power banks have revolutionized the way we charge our devices on the go, offering convenience and freedom from tangled cables. However, heat is rapidly generated during wireless charging, causing the output power to drop instantaneously, causing the claimed 15W output power to drop to 4-5W within 5 minutes. Why Do Wireless Power Banks Generate Heat? Wireless power banks operate on the principle of electromagnetic induction, allowing them to transfer energy to your device without physical connections. During this process, energy can be lost as heat due to various factors, including: Resistance: As electricity flows through the coils and internal components of the power bank, some resistance occurs, leading to heat production. Efficiency: Wireless charging isn't 100% efficient, and a portion of the energy is converted into heat instead of being delivered to the device. Fast Charging: Many power banks
