JTX BL-04 is an Android power cable battery connector built with an integrated ID resistor, designed for GSM technicians who need instant one-click boot on dead or battery-faulty Android phones. It solves no-battery detection, zero battery percentage, overheating alerts, and auto-shutdown problems during bench repair. The non-slip, non-loosening design keeps a stable connection while diagnosing or flashing, making it a useful boot-cable accessory for repair shops handling Samsung, Oppo, Vivo, Infinix, and Tecno devices across Pakistan.
