Universal Mobile Power Supply Cable – 4-Line Adjustable DC Cable for Smartphone Repair & Troubleshooting

Overview

The 4-Line Multi-Function Power Cable is designed specifically for professional mobile technicians. It allows you to simulate a battery connection, meaning you can power on a phone without the battery attached. This is critical for identifying whether a phone’s “no-power” issue is caused by a faulty battery or a short-circuit on the motherboard’s primary power line.

Key Features

• Universal Compatibility: Includes multiple connectors to fit the battery terminals of most modern Android and iPhone models.

• Precise Troubleshooting: Use it with your bench power supply to monitor current draw ($Ampere$) in real-time to spot shorts instantly.

• Adjustable Output: Allows for stable voltage injection directly into the phone’s power management circuit.

• Professional Grade: High-quality flexible silicone cables that stand up to daily use in a busy workshop.

• Safety First: Prevents the risk of accidentally shorting out tiny battery contact pins with loose wires.
