Introduction: Why it is important to know the type of connector of your smartphone
Modern smartphones, including the Xiaomi Redmi Note 8 Pro line, come with different types of charging and data connectors. Knowing the exact name and characteristics of your device’s connector helps avoid problems ranging from slow charging to damage to a port due to incompatible cable. For example, using a Micro-USB cable in a USB Type-C device is not just physically impossible — it can short circuit if you try to connect it through a low-quality adapter.
In the case of the Redmi Note 8 Pro, the question of the charging connector is also relevant because the model came out in 2019 - during a transition period when manufacturers massively abandoned outdated standards. Many users still confuse this smartphone with earlier versions of the Redmi Note, which used Micro-USB. This article will help to understand all the nuances: from the name of the connector to recommendations for choosing accessories.
The official name of the charging connector Xiaomi Redmi Note 8 Pro
Xiaomi Redmi Note 8 Pro is equipped with a USB Type-C (USB-C) connector - this is a modern universal standard that supports:
- 🔌 Quick charge (up to) 18W complete with the original adapter)
- 📤 High speed data transfer (up to 10 Gbps in theory, but limited to the smartphone controller)
- 🔄 Reversible connection (you can insert the cable by either side)
- 🎧 Support for analogue sound via an adapter (unlike some flagships, where USB-C digitally)
It is important to note that USB-C is only a connector shape, not a charging protocol. The connector itself does not guarantee high charging speeds: it depends on support for specific standards (for example, Quick Charge 3.0 or MediaTek Pump Express, which uses the Redmi Note 8 Pro).

If your smartphone suddenly stopped charging fast, check not only the cable but also the power supply.The original adapter from Xiaomi on the 18W has the MDY-08-EG or MDY-08-EM marking on the case.
USB-C and Micro-USB: Why Xiaomi has moved to the new standard
Xiaomi’s move to USB Type-C in the Redmi Note 8 Pro was driven by several key advantages:
| Characteristics | USB Type-C | Micro-USB |
|---|---|---|
| Maximum charging power | Up to 100W (theoretically), 18W for the Redmi Note 8 Pro | Up to 10W (limited by standard) |
| Data transfer speed | Up to 10–40 Gbps (USB 3.2/4.0) | Up to 480 Mbps (USB 2.0) |
| Durability | Up to 10,000 connection cycles | Up to 1,500-3,000 cycles |
| Support for video | Yes (DisplayPort Alt Mode) | No. |
Beyond the technical advantages, USB-C has become an industry standard: from 2022, the EU has mandated all manufacturers to use it to unify accessories. Even if you upgrade from an older Redmi model, switching to the Note 8 Pro means your old Micro-USB cables will become useless - you will have to buy new ones.

- ⚡ Fast charging: To get full charging 18W You need a cable with support USB 2.0 (or higher) and 5A Cheap cables are often limited to 2–3A, which reduces the charging speed.
- 🔗 Cable length: Cables longer than 1 meter can lose up to 20% of power due to resistance.
- 🛡️ Certification: Look for marking USB-IF (USB Implementers Forum is a guarantee of compliance with standards.
The Redmi Note 8 Pro is also compatible with:
