Compatibility with chargers: what can be used
One of the most common questions Redmi Note 8 Pro owners have is compatibility with charging. Let's see which adapters and cables are suitable for this model and which can cause harm.
1.Original charger
Included with the Redmi Note 8 Pro is a charger with the following characteristics:
- ⚡ Power: 18 Watt (9V/2A)
- 🔌 Connector: Micro-USB
- 🔋 Technology: Quick Charge 3.0
This is the best option for fast and safe charging, and the use of the original RAM guarantees stable operation and protection against overheating.
Third-party chargers
If the original RAM is lost or failed, you can use third-party adapters, but with reservations:
- ✅ Suitable: Charges with Quick Charge 3.0 support (e.g. from Samsung, OnePlus) Adapters with 10–18 W and 2A output current.
- ❌ Inappropriate: Charges over 20 watts (may damage the power controller); Cheap no-name adapters without certification; connector memory USB Type-C (without adapter).
Even if the charger is powerful, a poor-quality cable can limit current or cause overheating.
- 🔹 Original cable from the set.
- 🔹 Certified cables with labeling 28/24 AWG (thickness).
- 🔹 Ferrite ring cables (reduces interference).
💡
Using a charge above 18W without Quick Charge 3.0 support can overheat the battery and shorten its lifespan.
Frequent connector problems and their solutions
The Micro-USB connector in the Redmi Note 8 Pro may eventually fail due to mechanical damage, contact oxidation, or dust. Consider typical faults and how to fix them.
1.The smartphone is not charging
If the indicator does not light up when connecting the charging, the reasons may be as follows:

- 🧹 Connector contamination: gently clean the port with a cotton swab soaked in alcohol.
- 🔋 Power controller malfunction: Diagnostics required at service center.
2. poor contact (charging interrupted)
If charging is turned on, then it turns off, the problem most often is:
- 🔹 Worn connector contacts: over time, metallic "tongues" inside the port lose elasticity.
- 🔹 Cable bent plug: check if the connector on the cable is deformed.
The temporary solution is to slightly lift the cable up when you connect, but it's a signal that the connector needs to be replaced.
3.The computer does not recognize the smartphone
