iPhone Charging Cable Manufacturing Plant in Vietnam
iPhone Charging Cable Manufacturing Plant in Vietnam
In the phone charging ecosystem, charging cables play a role just as important as the charger itself. A low-quality cable can reduce fast charging efficiency, cause overheating, and even negatively impact the device's battery. MyMy Technology iPhone Charging Cable Manufacturing Plant in Vietnam. We are focusing on materials technology and engineering control to ensureiPhone charging cable for safe and fast charging.and stable.
Technical Challenge: Voltage Drop and Power Loss
Charging cables are the bridge that transmits energy. The transmission efficiency is governed by the impedance of the conductor.
1. iPhone Charging Cable and Voltage Drop - MyMy Technology
Voltage drop is the phenomenon where the voltage gradually decreases from the charger to the iPhone's input port.
- Reason:This is mainly due to the resistance of the conductor. The longer the wire, the smaller the core cross-section, and the lower the core material (for example, using an alloy core instead of pure copper), the greater the voltage drop.
- Consequence: If iPhone charging cables and voltage dropIf the voltage is too high, the iPhone will not receive the required voltage to activate fast charging mode (e.g., 9V), or the charging current will have to be reduced to protect the circuit, resulting in a much slower charging speed than the charger's wattage allows.
2. Minimizing Waste in iPhone Charging Cable Production
Reputable factories in Vietnam address the issue of energy loss by:
- High-quality copper core:Use pure, unadulterated, high-purity copper to reduce impedance.
- Increased core cross-sectional area (AWG):Especially for high-power cables (60W, 100W), the load-carrying wires (power and ground wires) must have a larger cross-sectional area (lower AWG) to reduce voltage drop and limitMinimize waste in the production of iPhone charging cables.energy in the form of heat.
Safe Current and Power Control
Charging cables not only transmit electricity but also must ensure a stable and safe current flow.
1. iPhone Charging Cable and Power Stabilizer - MyMy Technology
iPhone charging cable and power stabilizerThis is a key factor for battery health.
- Electromagnetic interference (EMI) control:A quality cable should have a shielding layer (usually aluminum foil or braided copper mesh) surrounding the wire cores. This shielding helps prevent electromagnetic interference from the external environment from affecting the transmitted current, ensuring that the power to the iPhone is "clean" and stable.
- iPhone charging cable factory controls the current:For USB-C to Lightning (PD) cables, the cable must contain an E-Marker (Electronic Marker) chip to communicate with the charger. This chip signals to the charger the maximum power the cable can handle, allowing the charger to supply the appropriate current and ensuring safety.
2. Power Control and Current Balancing - MyMy Technology
- Power control in iPhone charging cables:E-Marker chips are the main tool forPower control in iPhone charging cablesIt prevents high-power chargers from supplying excessive current that the cable is not designed to handle.
- Manufacture iPhone charging cables and balance current:The current must be evenly distributed throughout the power conductors. This is rigorously checked during manufacturing to avoid "hot spots" on the conductors, helping to...iPhone charging cable and power stabilizer factoryreached a high level.
High Power Output, Temperature, and Battery Life
The relationship between power output, temperature, and battery life is a primary concern for users.
1. The wattage of iPhone charging cables affects battery life. - MyMy Technology
- The wattage of iPhone charging cables affects battery life.This can happen indirectly through transmission quality. If a low-quality cable causes voltage drop, the iPhone has to draw a higher current to compensate, or the current is unstable, which can overheat the battery and cause it to age faster in the long run.
- iPhone charging cable factory and temperature control:High-quality cables use TPE (Thermoplastic Elastomer) or braided nylon sheathing materials, which offer good heat resistance and elasticity.Temperature controlThe benefits in these cables mainly come from reducing impedance and effectively dissipating heat into the environment.
2. Do High-Power iPhone Charging Cables Get Hot?
- Do high-power iPhone charging cables get hot?Yes, but if manufactured to the correct standards, the temperature increase will be within safe limits. Abnormal heating is often a sign of:
- High impedance:Poor quality wires cause energy to be converted into heat.
- Poor exposure:Loose or dirty contact pins on the Lightning or USB-C port can create high resistance at the contact point.
Performance Measurement and Quality Assurance - MyMy Technology
Reputable factories in Vietnam employ rigorous inspection processes to ensure quality.
iPhone Charging Cable Factory and Performance Measurement
- Measure DC impedance:This is the most basic but crucial test: measuring the impedance of the power cord cores and ground to ensure it is below the specified level (usually measured in milliohms/meter).
- Measure voltage drop under load: iPhone charging cable factory and performance testing.By applying the maximum current (e.g., 3A or 5A) and measuring the voltage at the cable output to confirm that the voltage drop does not exceed safe limits (typically below 500mV).
- Mechanical strength test:Perform tensile strength, flexural strength (Flexing Test), and plug/unplug strength tests on the connector to simulate real-world usage conditions.
