When it comes to charging Xiaomi Redmi smartphones, users often face confusion: which adapters come with the package, whether the model supports fast charging, and whether third-party chargers can be used without risk to the battery, especially for the Redmi Note, POCO and budget series, where the manufacturer has saved on trim in different regions.
In this article, weβll look at all the types of charging that were used in Redmi smartphones from 2018 to 2026, from the standard 5W to the ultra-fast 120W, and weβll also explore the nuances of wireless and reverse charging. Youβll learn how to check the adapterβs compatibility with your model, why the original cables are more important than they seem, and what to do if the phone is warming or slow charging. For convenience, weβve compiled a table with specifications for each series and added interactive widgets to help you find the optimal charger.
Types of charging in Xiaomi Redmi smartphones: from 5W to 120W
The Redmi range covers devices with different charging speeds - from the base models with 10W to the flagship Redmi K60 Pro with support for 120W. Consider the basic standards that are found in these smartphones:
- π Standard charging (5Wβ10W): It is used in budget models (e.g. Redmi). 9A or Redmi 10A). Usually there is an adapter in the package. 5V/1A or 5V/2A. This option is suitable for night charging, but during the day it may seem too slow.
- β‘ Fast charging (18Wβ33W): The most common variant for the Redmi Note series (such as Note 10 Pro or Note 12) uses Quick Charge 3.0 or MI Fast Charge: Charging up to 100% takes about 1-1.5 hours.
- π₯ Superfast charging (67Wβ120W): It is found in top models (Redmi). K50 Gaming, K60 Xiaomiβs HyperCharge technology allows you to charge your battery by 50% in 10-15 minutes.
- πΆ Wireless charging (up to) 50W): Supported in some models (Redmi) K50 Pro, Note 13 Pro+). Requires a special station and a compatible cover.
It's important to understand that charging power depends not only on the adapter, but also on the controller in the smartphone itself. For example, the Redmi Note 11 supports 33W, but you can also come with an 18W adapter to get the maximum speed, you have to buy a charger separately.
2.What charging comes with Redmi: comparison by model
The manufacturer often changes configurations depending on the region and year of release, and here is the current table for the popular Xiaomi Redmi models (2020-2026). Please note that in some countries (e.g. Europe), adapters may not be included due to environmental regulations.
| Model | Adapter power in the set | Max. Power maintained | Type of connector | Notes |
|---|---|---|---|---|
| Redmi 9A / 9C | 5W (5V/1A) | 10W | Micro-USB | In some regions, the adapter is not available. |
| Redmi Note 10 / 10S | 22.5W (9V/2.5A) | 33W | USB-C | 33W requires a separate adapter |
| Redmi Note 11 Pro / Pro+ | 67W (11V/6.1A) | 67W | USB-C | It comes with a branded cable. |
| Redmi K50 / K50i | 67W | 67W | USB-C | Supports Quick Charge 4+ |
| Redmi Note 12 Pro+ 5G | 120W | 120W | USB-C | Charge to 100% in 19 minutes |
Critical nuance: smartphones with support for 67W+ often require the original Xiaomi cable. Third-party USB-C cables may not withstand high currents, which leads to overheating or activation of protection (charging is at a reduced power).
β οΈ Note: If your Redmi is warming up while charging, check the adapter for compatibility. e.g. Redmi Note 10 Pro with an adapter on the 18W It will charge slower but safer than uncertified charging. 33W-block.
3. Can I use charging from other devices?
Many users are wondering whether an iPhone, Samsung or old Xiaomi charger will fit the new Redmi? The answer depends on three factors:
- Adapter power: If the unit supports Quick Charge or PD (Power Delivery), it is likely compatible. For example, the adapter from the MacBook (20Wβ30W) will suit the Redmi Note 12, but will not give maximum speed.
- Type of cable: For USB-C models (such as the Redmi K60), Micro-USB cables cannot be used, which will cause slow charging or port damage.
- Charging Protocol: Some Redmis (like the Note 11 Pro+) require a proprietary MI Fast Charge protocol.
Example of compatibility:
- β Charging from Xiaomi Mi 11 (55W) for Redmi K50 (67W) β will work 55W.
- β Can't: iPhone adapter 5W For the Redmi Note 12 Pro+ β charging will go 5-10 times slower.
- β οΈ Cheap Chinese Adapters Without Certification Could Damage Power Controller.

4.Fast Charging: How to Turn It On and Why It May Not Work
If your Redmi supports fast charging but it doesnβt activate, the reasons may be:
- π Turned off in settings: In some models (for example, POCO X3) There's an option called "Optimized Charging" that limits the current. β Battery β Charging settings.
- π Inappropriate adapter or cable: 33W+ You need a cable with support for high currents (usually included).
- π± Overheating: If the battery temperature is above 40Β°C. The system automatically reduces power.
- π Old version MIUI: Some firmware has a faulty fast charging. Update the software to Settings β The phone. β Updating the system.
To force fast charging on supported models:
- Connect the original adapter.
- Go to Settings β Battery β More
- Activate the Quick Charging option (in some versions of MIUI it is called Accelerated Charging).
- If you donβt have an option, your model doesnβt support it or you need an update.
What if the fast charging suddenly stopped working?
Important: On some models (e.g. the Redmi Note 10 Pro), fast charging is turned off when using the phone while recharging, and this is done to protect the battery from overheating.
5.Wireless and reverse charging: Which Redmi models support
Technology wireless charging (Qi) and reverse charging (Reverse Charging) has not yet become mainstream in the line of Redmi, but are found in separate models:
- π Reverse charging (up to) 10W): Allows you to charge other devices (such as headphones or smart watches) from your smartphone. K50 Gaming Redmi Note 12 Pro+ 5G POCO F4 GT To activate, go to Settings β Battery β Reverse charging.
- πΆ Wireless charging (up to) 50W): It is rare, only in flagship models: Redmi K60 Pro (30W) Redmi Note 13 Pro+ (50W, Requires a proprietary station) You need a compatible charging pad (for example, Xiaomi Mi Wireless Charging Pad).
Note that wireless charging is always slower than wired charging because of energy loss. For example, the Redmi K60 Pro charges 120W over wire in 19 minutes, and 30W wirelessly in 50 to 60 minutes.
β οΈ Note: When using reverse charging, your smartphone is discharged. It is not recommended to use this feature if the battery level is below 20% - this can lead to a sudden shutdown.
π‘
If your Redmi supports wireless charging but it is unstable, try removing the case β some materials (metal, magnets) interfere with power transfer.
6.How to prolong the life of a battery with frequent charging
Fast charging is convenient, but it can shorten battery life if you donβt follow simple rules.
- π Avoid full discharge: Optimal range of 20% to 80%. Regular discharge to 0% accelerates battery degradation.
- π‘οΈ Watch the temperature: Do not charge your phone at temperatures below 0Β°C or higher than 35Β°C. In the heat, turn off fast charging.
- π΅ Do not use your phone while charging: Games or videos put a strain on the processor, leading to overheating.
- π Use original adapters: Cheap chargers can deliver unstable voltages, which harms the power controller.
- π Calibrate the battery: Every 2-3 months, completely discharge and charge the phone to 100% to reset the controller statistics.
Newer versions of MIUI include Optimized Charging (Settings β Battery β Battery Health) which automatically limits the charge to 80% if the phone is connected to the network for a long time (e.g., at night), which increases battery life by 20 to 30%.
π‘
The most harmful scenario for the battery is to play heavy games (such as Genshin Impact) while charging fast, and the temperature can exceed 50Β°C, which is critical for lithium-ion batteries.
