Vietnam MyMy Technology Company Produces iPhone Fast Chargers

The difference between an iPhone fast charger and a cheap product is not in the outer shell, but hidden deep inside the circuit structure and electronic components. For reputable manufacturing units such as MyMy Technology, mastering the internal structure is key to ensuring performance and safety.

I. Charger Structure Anatomy: 3 Core Components

A standard fast charger, such as the one20W PDThe products that MyMy Technology produces are made up of three main components that determine quality:

1. Switching Circuit (PCBA - Printed Circuit Board Assembly): "Heart" of the Charger

• Smart control chip (Smart IC):This is the brain. This chip must be compatible with the protocol.PD (Power Delivery)to "communicate" with the iPhone, deciding on the optimal voltage and current levels. Quality manufacturers use chips from major brands to ensure accuracy and stability.
• Capacitors:Capacitors have the role of stabilizing voltage and filtering noise.
  • Solid Capacitors:Often preferred over electrolytic capacitors because they are more heat resistant, have a longer life and help the charger last longer after many years of use.
• Transformer:Responsible for reducing the voltage from $220V$ to a lower level. A high quality transformer must have good electrical isolation to ensure safety.

2. Thermal Management

In fast charging, the amount of heat generated is greater than normal charging. Poor heat management is the main cause of charger damage and affects the iPhone.

• Thermal paste/Gasket:High heat generating components (such as control chips, MOSFETs) are often glued or covered with thermal paste/pads to transfer heat to the case, helping to maintain stable operating temperatures.
• Optimal circuit design:MyMy and reputable units will design the circuit board (PCB layout) so that hot components are placed far apart, ensuring maximum air circulation inside the small space of the charger.

3. Protective Cover and Mechanical Structure

• One-piece casting shell (Ultrasonic Welding):Instead of using conventional screws or glue, quality chargers are often sealed using ultrasonic welding technology. This helps increase mechanical strength, prevent dust, and prevent parts from loosening due to impact.
• Secure plug:The plug material (brass or quality alloy) must ensure good electrical contact and withstand thousands of plugging/unplugging times without breaking or deforming.

II. Durability and Stability Test

MyMy Technology applies in-depth tests in the QA/QC process, going beyond basic safety tests:

In short: Choosing a iPhone fast charger from manufacturers capable of mastering technical factors and rigorous testing processes such as MyMy Technology is a guarantee of stable, durable and absolutely safe charging performance for your device.
