Charging for Xiaomi Mi 9: the official name, characteristics and how not to buy a fake

If you are a Xiaomi Mi 9 owner and are looking for a replacement for your native charger, you may have encountered a confusion of names. The manufacturer uses complex code names that are not always clear to the average user. In this article, we will understand what the official name of the charging for Xiaomi Mi 9, what its technical characteristics are and how to distinguish the original from cheap fakes that can spoil the battery.

Xiaomi Mi 9 supports fast charging Quick Charge 4+ and comes bundled with a proprietary power adapter. However, when buying a new RAM, it is important to know not only the name, but also the key parameters: power, output voltage and compatibility with protocols. We will also tell you where to buy original accessories and what to do if your native charging breaks.

Official name of the charger for Xiaomi Mi 9

The charger that comes with the Xiaomi Mi 9 has the following full name:

Xiaomi MDY-11-EP (18W, Quick Charge 4+)

This is an official designation from the manufacturer that you can use when searching online stores. MDY-11-EP is Xiaomi's internal article, which makes it easy to identify the original device. It is important to note that variations of this code can be used for different regions (for example, MDY-11-EC for China), but they are functionally identical.

Alternative names can also be found on sale:

• 🔌 Xiaomi Charger 18W Quick Charge 4+ (simplified)
• 📦 The original Xiaomi adapter for Mi 9/9 SE/9T (universal 9)
• ⚡ Power supply unit Xiaomi Type-C 18W (lens)

If you see these specifications in the product description, it is likely to be an original or certified accessory, but always check the model code (MDY-11-EP) on the case or packaging.

Technical characteristics of the original charging

To make sure you don’t make a mistake when buying, it’s important to know the key parameters of the native adapter. MDY-11-EP:

The adapter features support for multiple fast charging protocols, which means it is compatible not only with the Xiaomi Mi 9, but also with other devices that support Quick Charge 4+ or USB Power Delivery, such as the Mi 9 SE, Mi 9T, and some other brands (provided protocol compatibility is available).

Note that if you buy a charge with less than 18 watts, the smartphone will charge more slowly. and if the power is higher (for example, 30W or 65W), then the Mi 9 will still limit the consumption to 18 watts - it is safe, but it is pointless to overpay for extra watts.

💡

If you travel frequently, look out for compact versions of Xiaomi’s original chargers (like the MDY-12-EP) that have foldable plugs and support the same protocols but take up less space in your bag.

How to distinguish the original charging from a fake

The smartphone accessories market is flooded with cheap fakes that not only slow the charger, but can also knock out the battery or even cause a fire. Here are the key signs of the original Xiaomi MDY-11-EP charging:
