Vietnam iPhone Charger Manufacturing Factory
In the era of strong technological development, iPhone chargers are not only common accessories but also important factors that directly affect the battery life and safety of the device. Choosing the right standard charger helps users avoid battery failure, overheating or the risk of fire or explosion. In Vietnam, MyMy Technology is a reputable iPhone charger manufacturerTrusted by many people because it meets international standards for quality and safety.
1. How to distinguish between 5W, 18W, 20W and 30W iPhone chargers
Each iPhone line will be compatible with different charging power levels.
- 5W charger: is the old standard type, slow charging, suitable for previous iPhone models such as iPhone 6, 7, 8.
- 18W charger: supports fast charging, compatible with iPhone X, iPhone 11.
- 20W charger: commonly used today, capable of charging from 0% to 50% in about 30 minutes, suitable for iPhone 12 to iPhone 15.
- 30W charger: for iPad, MacBook Air or iPhone 15 Pro Max – where higher power is needed for fast, safe charging.
When choosing to buy, users should carefully read the parameters printed on the charger and make sure that the device clearly states the capacity (Output: 5V/3A, 9V/2.2A, 15V/2A...) and safety standards such asCE, RoHS, PD Certified.
2. What is GaN? Advantages of GaN chargers over conventional silicon chargers
GaN (Gallium Nitride)is a new semiconductor material technology that helps reduce the size of the charger while still maintaining high capacity. Compared with traditional silicon chargers, GaN chargers have outstanding advantages:
- Compact size, convenient to carry when traveling.
- High charging efficiency, save energy.
- Good heat dissipation, limit device heat when charging for a long time.
- Longer life, reducing wear and tear on internal components.
Workshop MyMy Technology GaN technology has been applied in the production line, helping the product achieve high performance while still ensuring absolute safety for iPhone and iPad devices.
3. How to identify a charger that meets PD 3.0 and PD 3.1 standards
Standard Power Delivery (PD)is a fast charging technology officially supported by Apple.
- PD 3.0: allows maximum charging capacity up to 60W, suitable for current iPhone and iPad lines.
- PD 3.1: is an upgraded version, the capacity can reach up to 140W - used for iPhone 15 Series, MacBook and iPad Pro.
To check if the charger meets PD standards, users should look at the label or print on the product with the symbol "PD 3.0" or "PD 3.1", along with the certificate.USB-IF Certified. MyMy Technology is one of the few factories in Vietnam to achieve this certification, ensuring perfect compatibility with the Apple ecosystem.
4. Will the iPhone charger explode if the wrong voltage is used?
Genuine chargers are designed with voltage regulator circuits, so explosions are rare if used properly. However, when used fake charger, unknown origin, unstable current can cause:
