Xiaomi Redmi connectors: a complete reference model (2013–2026)

When choosing a Xiaomi Redmi smartphone or accessories, many people are faced with the question: what connector is used in a particular model? The type of connector depends not only on the compatibility with chargers, but also on the speed of data transfer, the ability to connect external devices, and in some cases even the functionality of a smartphone. In this article, we will analyze the evolution of connectors in the Redmi line from 2013 to today, compare their specifications and give recommendations for the choice of cables and adapters.

It's important to understand that the type of connector is not just a charging hole, but it depends on whether you can use a fast charger, connect your smartphone to a monitor via USB-C to HDMI, or charge it from an old-fashioned power bank. We analyzed more than 50 Redmi models to create a current compatibility table and identify key differences between Micro-USB, USB Type-C and rare exceptions.

The evolution of connectors in Xiaomi Redmi smartphones: from Micro-USB to USB-C

The Redmi line debuted in 2013 with the Redmi 1 model, which used the classic Micro-USB, the standard of the time, and this connector dominated budget smartphones until 2016, when Xiaomi began gradually moving to USB Type-C. The turning point was the Redmi Note 5 (2018), after which all flagship and most mid-budget models received a modern connector.

But even today, there are new Micro-USB devices on the market, like the Redmi A or Redmi Go over budget. Why is that? It's about cost: USB Type-C increases the price of a smartphone by 3 to 7 percent because of the more complex design and certification. For devices under 10,000 rubles, this can be critical.

• 📅 2013–2017: All Redmi models were equipped with Micro-USB (including Redmi) 4X, Redmi Note 4).
• ⚡ 2018–2019: Gradual transition to USB-C Note and K series (e.g. Redmi) K20 Pro).
• 🔄 2020–2026: USB-C It is the standard for all models except ultra-budget models (e.g. Redmi). A1+ micro-USB).

Fun fact: Xiaomi has never used proprietary connectors (like Apple’s Lightning) — even in its earliest models — that have made the accessory ecosystem more open, but created confusion for users who don’t keep up with lineup updates.

Table of connectors by Xiaomi Redmi models (2013–2026)

To avoid guessing which cable will fit your model, we have compiled a detailed table that includes all of Redmi’s key devices, and also shows the supported charging standards, and note that even if the model has USB-C, it doesn’t guarantee fast charging support, it depends on the power controller.

⚠️ Note: If your model is not listed in the table, check the connector visually. USB-C It has an oval shape and a symmetrical connector (inserted by either side), whereas the Micro-USB is a trapezoidal and requires correct orientation. Also note the marking on the smartphone case - sometimes there is a charging standard (for example, the standard for charging is specified there, QC 3.0 or PD 3.0).

USB-C vs Micro-USB: Which is Best for Xiaomi Redmi?

The transition from Micro-USB to USB-C is not just a marketing move, but it offers a number of technical advantages that are particularly important for today’s smartphones:

• ⚡ Fast charging: USB-C Supports Quick Charge 4 protocols+, Power Delivery (PD) and proprietary Xiaomi solutions (e.g. HyperCharge before the 120W). Micro-USB is limited to 18W even in the best of cases.
• 🔄 Reversibility: The connector is inserted by either side - there is no risk of damaging the port if you fail to try.
• 📤 Transfer of data: USB-C Redmi is usually implemented as USB 2.0 (up to 480 Mbps), but in flagships (e.g. Redmi) K50) maybe USB 3.2. up to 10 Gbit/s).
• 🎮 Expanded functionality: Through USB-C plugged in HDMI-adapter, gamepad or even external SSD (supported OTG).

However, Micro-USB has one advantage: the cheapness of accessories. Cables and charging costs 2-3 times cheaper than USB-C. This is critical for ultra-budget models, where every ruble counts, and Micro-USB is less susceptible to mechanical damage when side loads (for example, if the smartphone falls on the cable).

💡

If your Redmi supports fast charging, but you use a regular USB-C cable, the charging speed can drop to 5W. Always check the cable’s compatibility with the protocol (QC, PD, etc.).
