Wireless Power Bank-a hnathawh dan tur principle .

Wireless power bank hian a bik takin technology engemaw zat a rinchhan a, chungte chu electromagnetic induction, electromagnetic resonance, radio wave leh electric field coupling te an ni. Chumi zingah chuan electromagnetic induction hi a transformer-like principle avang hian hman a ni nasa hle. Wireless power bank-a transmitting coil chu alternating current-a connect a nih chuan, magnetic field danglam tak a lo awm ang a, receiving end-a device coil chuan magnetic field-ah current a induce ang a, chu chuan device chu a charge ang. Electromagnetic resonance type hian vibration frequency inang nei thil pahnih inkara efficient energy transmission characteristics a hmang a, natural frequency inang coil setting hmangin energy transmission tha tak a hmu bawk. Radio Wave Type Wireless Power Bank hian electromagnetic wave te chu electromagnetic wave generator leh antenna hmangin device hmanga hman theih turin electrical energy ah a chantir thin a ni. Electric Field Coupling Type Wireless Power Bank chuan metal plate hmangin coupling capacitor a siam a, direct-in high-Frequency electric field chu charging stand leh appliance inkarah a siam a, electrical energy wireless transmission a hmu thei a ni.
