MyMy Technology manufactures iPhone charging cables in Vietnam.

In the ecosystem of phone accessories, charging cables act as the "lifeblood" that transmits energy. MyMy Technology We don't just manufacture a cable; we create a comprehensive battery protection solution, ensuring stability from resistance to touchscreen functionality.

1. Why does charging when the device is hot cause battery drain and damage the device?

Temperature is the number one enemy of lithium-ion batteries. When you plug in your phone to charge while it's hot (due to playing games or using demanding apps), a "heat buildup" phenomenon will occur:

• Pressure on battery chemicals:High temperatures cause lithium ions to move erratically, leading to the phenomenon of "phantom battery" and rapid battery drain after unplugging.
• Component aging:High temperatures emanating from the charging cable can degrade the lifespan of the power IC inside the device.

2. The role of casing thickness and wire core quality in battery power.

A quality charging cable from the factory MyMy Technology. It is composed of two core elements:

• Protective casing thickness:The TPE plastic or braided fiber casing not only prevents breakage but also acts as an effective insulator, preventing heat from the copper core from transferring back to the user's hand and the device.
• Low resistance:A large cross-sectional area of ​​pure copper core helps reduce resistance (R). According to the formula P = I^2 .R, the lower the resistance, the less power is lost as heat, resulting in faster charging and a cooler device.

3. The link between poor quality cables and touch screen malfunctions.

Have you ever experienced a situation where the touchscreen becomes unresponsive while charging? The main reason lies in… anti-interference capability of the cable:

• Cheap cables lack an aluminum shielding layer to prevent interference, allowing electromagnetic interference to leak to the screen.
• Fluctuating currents can interfere with the capacitive touch layer, causing the iPhone to respond incorrectly or the screen to "jump" repeatedly.

4. How often should I replace my charging cable?

Charging cables have a limited lifespan depending on how often they are used. MyMy TechnologyWe recommend replacing the cable when:

• After 12-18 months of use: Even though the wire isn't broken, the insulation inside may have aged, increasing resistance and reducing charging efficiency.
• When the cable end is loose: If you have to "stretch" or "bend" the charging cable for the device to charge, replace it immediately to avoid short circuits and damage to the charging port.
• The cable sheath is peeling off:A damaged protective layer will cause electrical leakage, posing a danger to users and easily causing electric shocks to iPhones.

5. Standard production process at Mymy Technology Vietnam factory

To meet export orders, each cable at our factory must pass three rigorous tests:

1. Impedance measurement test:Ensure the output voltage is accurate to the nearest mV.
2. Swing Test:The cable neck is reinforced to withstand over 15,000 bends.
3. Load current test:Ensures support for PD fast charging up to 27W for iPhones without generating heat exceeding 35°C.
