Xiaomi charging connector: what is the name and what are the types

You just bought a new Xiaomi smartphone or are planning to upgrade accessories, but are not sure what connector you need to charge? This confusion is not surprising: over the past 10 years, the company has used three different types of connectors, and the transition between them has been gradual. In this article, we will understand what the charging connector is called on Xiaomi depending on the model, what the USB-C, Micro-USB and proprietary options differ from, and give tips on the choice of cable and adapter.

Let’s note right away: if your smartphone is released after 2018, it has a 99% probability of a USB Type-C connector (or just a USB-C). But for older models (for example, the Redmi 4A or Mi A1), Micro-USB is still relevant. But the owners of the Mi Band smart watch or Xiaomi AirDots headphones will have to deal with magnetic connectors or wireless charging. Next, a detailed guide with tables, comparisons and life hacks.

1. The main types of charging connectors in Xiaomi devices

Xiaomi uses three types of charging connectors, and each of them has its own characteristics:

• 🔌 USB Type-C (USB-C) — The current standard for most smartphones, tablets and laptops, a symmetrical connector that supports fast charging and data transfer at high speeds.
• 📱 Micro-USB is an outdated connector, which until 2018 was installed on the budget models Redmi and Mi. Slower and less reliable than the current model. USB-C.
• 🧲 Magnetic/proprietary connectors – used in smartwatches (Mi Band), headphones (AirDots) and some accessories.

It is important to understand that the type of connector affects not only the compatibility of cables, but also the charging speed. For example, USB-C in Xiaomi smartphones supports Quick Charge (HyperCharge), while Micro-USB is limited to the standard 5V/2A.

2. USB-C vs Micro-USB: How to determine which connector your Xiaomi has

If you are not sure what connector your smartphone has, use simple visual signs:

• 🔍 USB-C — oval, symmetrical connector (can be inserted by either side) used in models starting with Xiaomi Mi 8 (2018 year and all Redmi Notes 7/8/9/10/11/12.
• 🔄 Micro-USB is a trapezoidal connector (only one right side to connect). 4/5, Mi A1/A2, Mi Max 2 and older devices.

You can also check the specifications on the official Xiaomi website or in the documentation for the device. If there is no box at hand, look at the marking next to the charging port - sometimes it indicates the type of connector.

💡

If your smartphone supports fast charging but doesn’t charge fast, check the cable and adapter. Cheap accessories may not meet USB-C Power Delivery or Quick Charge standards.

3.Why Xiaomi switched from Micro-USB to USB-C

The switch to USB-C was inevitable for several reasons:

1. Standardization: Since 2018, USB-C has become mandatory for all new smartphones in the EU and later in other regions.
2. Fast charging: USB-C supports Quick Charge 4+, HyperCharge (up to 120W) and Reverse Charging.
3. Durability: A symmetrical connector breaks less frequently.
4. Universality: one cable for a smartphone, laptop, headphones and other gadgets.

The last flagship with Micro-USB was Xiaomi Mi 6 (2017). Already in Mi 8 (2018), the company completely switched to the new model. USB-C, The budget Redmi has updated the connector for 2019-2020, with the exception of some accessories (for example, the Mi Band), where USB-C It is not suitable due to its miniature size.

💡

Since 2020, all Xiaomi smartphones (including budget Redmi) are equipped with a USB-C connector. Micro-USB remained only in accessories and devices until 2018.

4. Magnetic connectors in smart watches and headphones Xiaomi

If you have a Mi Band, a Xiaomi Watch, or an AirDots wireless headphone, you can't find standard USB-C/Micro-USBs.

• 🕒 The Mi Band magnetic connector is two metal contacts on the back of the bracelet that magnetize to the charging cable. It's easy to contaminate, requires careful handling.
• 🎧 Pogo-pin for AirDots — contacts inside the case that charge the headphones when closed.
• ⚡ Wireless charging (Qi) – used in some smartwatch models (Xiaomi Watch) S1) and powerbank.

The main problem with these connectors is fragility, for example, Mi Band contacts are often oxidized by sweat or moisture, and charging cables are easy to lose, we recommend storing accessories in a dry place and periodically cleaning the contacts with an alcohol napkin.

5. How to Choose a Cable and Adapter to Charge Xiaomi

Even if you know the type of connector, not all cables and adapters are equally useful.

Look for USB-C to USB-C (for fast charging) |Check Quick Charge or Power Delivery | Avoid over-cheap cables (risk of overheating) | For older models with Micro-USB, choose thickened wiring |Note the length (1-2 meters optimal for the home)

-->

For smartphones with fast charging (for example, Xiaomi 12 Pro or Redmi Note 11 Pro+) you need an adapter with a power of 33W. Complete with flagships comes a charger for 67W or 120W, but it can be purchased separately. Budget models (Redmi 10A) are usually equipped with 10W adapters.

⚠️ Warning: Using uncertified cables or adapters can cause the battery to overheat or even catch fire. USB-C-cables to powerful charging (67W)+).

6. Frequent problems with charging connectors and how to solve them

If Xiaomi smartphone is poorly charged or the cable is not held in the connector, the reasons may be as follows:

• 🔌 Connector contamination is dust, pile, or contact oxidation. Solution: brush with a toothpick (carefully!) or compressed air.
• 🔥 The jack is a common problem after a year of use, solution: soldering contacts at the service center or replacing the connector.
• ⚡ The cable or adapter is faulty - try another kit. Xiaomi's original accessories last longer.
• 📉 Software failure - sometimes the system restricts charging.Solution: reboot your smartphone or reset settings (Settings) → System system → Resetting settings).
