Vietnam iPhone Charger Export Company - MyMy Technology 

In the era of increasingly powerful mobile devices, iPhone chargers are not just accessories, but also a decisive factor in battery life and user experience. Vietnam is gradually becoming a center for manufacturing and exporting high-quality iPhone chargers, including Company MyMy Technology is one of the pioneering enterprises providing international standard chargers, using smart IC chips, advanced GaN, PD and PPS technology.

1. Can 120W GaN charge iPhone?

The answer is, but on condition that the iPhone supports the corresponding charging standard. Technology GaN (Gallium Nitride)allows for greater power transmission, lower heat dissipation, and saves component space. With the charger GaN 120W, you can charge your iPhone, iPad, or MacBook at the same time while ensuring voltage safety. However, the iPhone will automatically receive the appropriate maximum power, for example 20W with iPhone 13 or 27W with iPhone 15 Pro Max.

2. How does Power Delivery (PD) technology help charge faster?

Power Delivery (PD)is a fast charging standard developed by USB-IF, which increases voltage and current up to20V – 5A, equivalent to power100W. For the iPhone, PD allows charging from 0–50% in just 30 minutes.
iPhone chargers that meet PD 3.0 and PD 3.1 standard products are integrated with current control chips, ensuring fast charging speed while maintaining stable temperature, protecting the battery from overload and overheating.

3. What is the difference between PPS and PD in iPhone charging?

PPS (Programmable Power Supply) là enhanced version of PD, allowing continuous voltage and current adjustment according to the device's needs.

• PD: transmits energy at fixed levels (such as 5V, 9V, 15V).
   
• PPS: can be flexibly customized as 8.5V, 8.8V, helpingOptimize performance and reduce machine heat.
   

Some charging lines of MyMy Technology PPS have now been applied to be compatible with new iPhone devices and high-end Android phones, providing superior charging performance while still saving energy.

4. Does fast charging heat up the device?

Reality, All fast charging technologies generate heat., but if well controlled, this is completely safe.
Thanks to the smart control IC chip, MyMy charger can automatically cut off or reduce current when it detects a temperature higher than the safe level. This helps maintain battery life and avoid battery swelling or explosion - common in cheap, substandard products.

5. How does the smart IC chip in the charger identify the device?

Each mobile device has the ability to receive different voltages. The smart IC chip in the MyMy charger is capable of:

• Identify connected devices (iPhone, iPad, MacBook, etc.)
   
• Adjust the current and voltage appropriately
   
• Circuit breaker in case of overcurrent or short circuit
  Thanks to that, the charging process is smoother, more stable and safer than floating chargers without protection circuits.
   

6. Why does a genuine charger charge faster than a fake charger?

The difference lies in the quality of components and charge controller
