The Xiaomi Redmi Note 8, released in 2019, is still a popular smartphone due to its balanced specs and affordable price. However, over time, even the most reliable gadgets wear out accessories — especially charging cables. Non-original or substandard wires not only slow down charging, but can damage the battery or USB-C port. In this article, we will examine which cable is suitable for the Redmi Note 8, how to distinguish the original from a fake and what to look for when buying.
Note: Redmi Note 8 supports fast charging power up to 18 watts (Quick Charge 3.0 technology), but only when using a compatible cable and adapter. If you connect your smartphone to a conventional charger by 5 watts, charging time will increase by 2-3 times. In addition, not all USB-C cables are the same: some are designed only for data transfer, others are for high current.
Technical Charging Characteristics of Redmi Note 8
Before you buy a new cable, study the key charging options of your smartphone:
- 🔌 Type of connector: USB Type-C (symmetrical, supports two-way connection).
- ⚡ Maximum power: 18 W (9 V/2 A) using the original Xiaomi adapter.
- 🔋 Fast Charging Protocol: Quick Charge 3.0 (compatible with the USB Power Delivery up to 15 watts).
- 📏 Cable length: original cable complete – 1 meter (convenient for home use).
Important: The Redmi Note 8 doesn’t support ultra-fast charging (like the Redmi Note 10 Pro or POCO F3), so it doesn’t make sense to buy cables above 18W. However, if you use a 20-30W adapter (like a MacBook or iPad Pro), the smartphone will only take the power it’s designed to run — there won’t be overload.
Another caveat: the cable must support data transmission (if you connect your phone to a PC for synchronization), and cheap charging cables often lack this feature.
Original vs. Compatible Cable: Which is Better?
The original cable from Xiaomi (MTC-002 or MTC-003) guarantees:
- ✅ Stable charging at maximum power (18 W).
- ✅ Protection against overheating and short circuit (inline control chip).
- ✅ Long service life (original cables are designed to be used for the ~10,000 connections).
But original accessories cost more – from 500 to 1000 rubles depending on the length. Compatible cables (for example, from Baseus, UGREEN or Anker) can be no worse if:
- 🔍 They're certified. USB-IF (packet).
- 🔧 Maintain current up to 2-3 A (indicated on the cable shell).
- 🛡️ Equipped with protection against voltage drops.
Warning: Cheap unlabeled cables (especially from AliExpress or markets) can damage the USB-C port due to poor soldering or lack of shielding.
💡
Before buying, check the reviews of the cable at sites like Yandex Market or Wildberries. Pay attention to photos of real customers - often fakes give themselves off as poor-quality packaging or crooked font on the label.

Critical information: if you use an adapter with a power of 18 watts, but the smartphone charges slowly (for example, up to 100% in 3+ hours), the problem is precisely in the cable - replace it with a model with support for current from 2 A.
How to check the cable for performance
There are several ways to diagnose a faulty cable:
- Visual examination: 🔍 Check the connector. USB-C for the presence of bent contacts or oxidation. 🧵 Check the squirt at the base - if it cracks, soon the cable will break.
- Testing on another device: 📱 Connect the cable to another smartphone with USB-C (For example, Samsung Galaxy or Google Pixel). ⚡ If charging is fast, the problem is in the port of your Redmi Note 8.
- Current measurement: 📊 Use the Ampere app (available on Google Play) to check the current strength. ⚠️ Norm for fast charging: 1,500–2,000 mA. If less than 500 mA, the cable is faulty.
Look at the connectors under the light|Connect to another device|Check the current at Ampere|Try another adapter.-->
If the cable has passed all the tests, but charging is still slow, clean the Redmi Note 8 port of dust with a wooden toothpick (not metal!).
Frequent mistakes when choosing a cable
Many users make the same mistakes that lead to breakdowns, and here are the most common ones:
⚠️ Warning: Never use Micro-USB connector cables through an adapter! this can burn the smartphone power controller due to mismatch of voltages.
- 🚫 Buying "universal" cables without specifying the current to be maintained, often designed for only 0.5-1 A.
- 🔥 Using damaged cables with bare wires - the risk of short circuit.
- 🔄 Frequently changing cables between devices (for example, charging the Redmi Note 8 from the iPhone cable.
- 💧 Charging in wet conditions (e.g. bathroom) Even if the cable is in good working order, moisture can oxidize the contacts.
Another common problem is that people confuse cable and adapter, like buying an expensive Anker cable, but they keep using an old 5W adapter. In this case, charging will still be slow. To get 18W, you need both a cable and an adapter that supports Quick Charge 3.0.

Where to buy a high-quality cable for Redmi Note 8
We recommend buying cables in trusted places to avoid counterfeiting:
- 🛒 Official Xiaomi Store: ✅ 100% original, warranty 1 year. ❌ Prices are higher than those of resellers (but justified by quality).
- 🌍 Wildberries / Ozone / Yandex Market: ✅ A wide range of reviews, real buyers. ❌ Risk of getting a fake (check the seller’s rating).
- 🏬 Network stores (Svyaznoy, M. Video, Citilink): ✅ You can touch the product before buying. ❌ Limited selection of brands (most often only Xiaomi and Baseus).
- 🌐 AliExpress / Amazon: ✅ Low prices, many options. ❌ Long delivery, high chance to receive low-quality goods.
Tip: If you buy on the marketplace, look for sellers with a rating above 4.8 and the number of reviews from 100+. Pay attention to the photos of the package - the original Xiaomi cables have a hologram and a barcode on the box.
💡
The best combination of price/quality is the Baseus and UGREEN cables with USB-IF certification. They are cheaper than the original ones, but they are not inferior in reliability.
