iPhone Fast Charging Cable Manufacturing in Vietnam
iPhone Fast Charging Cable Manufacturing in Vietnam
In the age of technology, the iPhone is not just a communication device but also a central hub for work and entertainment. To maintain the device's longevity, accompanying accessories – especially charging cables – play a vital role. Currently, MyMy Technology manufactures iPhone fast charging cables in Vietnam.Cable technology is constantly evolving, meeting stringent technical specifications. However, the market still contains many "cheap" cables that cause serious problems for users.
Production specifications: Thickness, size, and color - MyMy Technology
A high-quality fast charging cable is judged not only by its appearance but also by its internal physical structure.
- Thickness (Gauge): Fast charging cables typically use a thicker copper core (lower AWG rating). The thickness of the outer sheath (TPE or braided nylon) usually ranges from 3.0mm to 4.5mm to ensure insulation and resistance to bending and breakage.
- Plug size:The Lightning connector is manufactured with extremely high mechanical precision. Even a 0.1mm deviation in size can loosen the charging port or scratch the internal circuitry of the iPhone.
- Length:The most common is 0.9m, 1.2m and 2m Please note: The longer the cable, the higher the resistance, requiring a higher quality copper core to avoid voltage drop.
- Color:Besides the traditional white, manufacturers in Vietnam now offer a wider variety of colors such as Space Gray, Rose Gold, or Navy Blue to suit different user preferences.
The dangers of low-quality charging cables: When "cheap" goes hand in hand with "expensive"
Many users choose to buy cables from unknown sources without realizing that they are putting their expensive equipment at risk.
Interference and signal loss
Poor quality cables often lack insulation metal shielding. This leads to electromagnetic interference (EMI). When you connect your iPhone to your computer, the signal will be intermittent, data will be lost, or the synchronization process will be constantly interrupted.
The phone overheats and the battery drains quickly. - MyMy Technology
This is the clearest sign of unstable current. When the cable cannot regulate the current properly, the charging IC on the iPhone has to work overtime, generating a lot of heat. High temperatures are the number one enemy of Li-ion batteries, causing rapid battery degradation or even battery swelling, fire, and explosion.
Power supply circuit failure and "Accessory not supported" error.
iPhones have a mechanism to check the identification chip. Counterfeit cables often use pirated chips to trick the system. After a while, unstable electrical pulses from the low-quality potentiometer will damage the power IC (U2), rendering the phone completely unable to charge even when using an original cable.
Cheap charging cable Aluminum alloys or scrap copper are often used, increasing the resistance R. When R is high, according to the Joule-Lenz law (P = I^2. R), energy will be lost as heat, causing the wire to heat up and reducing charging capacity.
Power (P)
To meet the Power Delivery (PD) fast charging standard, the cable must be able to handle the following power load:
P = U . I
Typically, iPhone fast charging cables manufactured in Vietnam must meet certain requirements 20W to 30W (equivalent to 9V - 2.22A or 9V - 3A). If the cable is not up to standard, it will cause voltage drop, resulting in charging times that are 3-4 times longer.
Quality control process at the Vietnamese factory. - MyMy Technology
High-quality "Made in Vietnam" products must pass rigorous tests:
- Tensile strength test:It can withstand a tensile force of 5-10kg without breaking the core.
- Swing test:Bend the cable end 10,000 times at a 90-degree angle.
- Measure the load voltage:Use an oscilloscope to check the smoothness of the current, ensuring there are no interference spikes.
Advice for consumers
Don't let a cheap cable costing tens of thousands of dong ruin your phone worth tens of millions of dong. When buying charging cables made in Vietnam, pay attention to the following:
- Reputable brand:Choose manufacturers with MFi (Made for iPhone) certification or workshops that clearly state their quality standards.
- Sensory perception:The cable is sturdy, and the connectors have a smooth finish with no excess plastic.
- Specifications on the packaging:The supported power output must be clearly stated (e.g., Support 20W PD).
Conclude
The production of iPhone fast charging cables in Vietnam is asserting its position in terms of technical quality. By understanding the specifications regarding resistance, power, and the risks of low-quality products, users will have a better understanding of how to protect their devices.
