Relife XA4 Pro Power Cable for Apple iPhone 8 – 17 Pro Max Series
The professional Relife XA4 Pro power and diagnostic cable is an essential tool for GSM service labs and technicians specialized in repairing Apple devices. Designed to supply power directly to the motherboards without the need for a mounted battery, it allows quick phone startup (one-button boot), precise current consumption measurement, and short circuit diagnosis on the main power lines. The cable covers a wide range of Apple generations, from the iPhone 8 series up to the iPhone 17 Pro Max, integrating dedicated FPC connectors with millimeter tolerances for a firm and secure fit on the battery sockets.Equipped with intelligent protection circuits and chips for automatic recognition of the original battery protocol, the Relife XA4 Pro prevents overheating, overvoltage, and accidental motherboard restarts during testing. High conductivity pure copper conductors ensure minimal voltage drop, while the flexible sheath and reinforced connectors guarantee high durability for intensive use at the workbench.
