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.

Features:
- Wide compatibility: Apple iPhone series 8 up to series 17 Pro Max (including Plus, X/XS/XR, Pro, and Pro Max models)
- One-Button Boot function: Dedicated button to simulate the phone's power button press directly from the cable
- Intelligent protection: Built-in protection against overvoltage, overcurrent, and polarity reversal
- Dedicated FPC connectors: High-precision flexible plugs ensuring a secure and firm connection without damaging the motherboard pins
- Battery protocol simulation: Integrated chips for correct parameter communication to the PMIC, preventing automatic restarts
- Power source connection: Standard banana/fork type connectors for universal compatibility with any adjustable laboratory power supply (DC Power Supply)
- Materials: Flexible silicone cable resistant to heat and mechanical wear, with high-purity copper conductors
- Applications: Short circuit diagnosis, standby/boot current measurement, motherboard startup during testing phase
