Xiaomi laptops have gained popularity due to a combination of performance, design and affordable price. However, when buying or replacing a charger, many people are faced with the question: how many watts does it take to charge a Xiaomi laptop? The answer depends on the model, generation and even equipment of the device. Using an inappropriate adapter can lead not only to slow charging, but also to damage to the battery or ports.
In this article, we will discuss in detail:
- 🔋 Standard charging power for different Xiaomi lines (Mi Notebook, RedmiBook, Mi Gaming)
- ⚡ What happens if you use an adapter with less or more power?
- 🔍 How to check the compatibility of the charger with your model
- 🛒 Recommendations for the selection of original and third-party adapters
We will pay special attention to hidden nuances that are rarely mentioned in the instructions – for example, why some RedmiBook 15 2023 models require 100W adapters, although the specifications are specified as 65W.
Standard power chargers for Xiaomi laptops
Xiaomi launches laptops in three main lines: Mi Notebook (premium segment), RedmiBook (budget and medium-sized models) and Mi Gaming (gaming devices), chargers vary from 30 watts to 240 watts depending on the configuration.
Here are the basic values for popular models:
| Line/Model | Standard power adapter (W) | Type of connector | Year of release |
|---|---|---|---|
| Mi Notebook Air 12.5" | 30-45 W. | USB-C | 2016–2018 |
| RedmiBook 14/15 (RYZEN) | 65 W. | USB-C | 2020–2022 |
| Mi Notebook Pro X 15" | 100-135 W | USB-C | 2021–2023 |
| Mi Gaming Laptop 2023 | 230-240 W | Propietary (branded) | 2023–2026 |
| RedmiBook Pro 15 (2026) | 100 W. | USB-C (PD 3.1) | 2026 |
Note that the power of the adapter is not always equal to the maximum power consumption of the laptop. For example, the RedmiBook 16 Pro can consume up to 80 watts for a short time at high load, but comes with a 65-watt adapter. This is normal - the manufacturer takes into account average use cases.
What happens if you use a different power charger?
Many users wonder whether it is possible to charge a Xiaomi laptop with a smartphone adapter (for example, 33 watts) or, conversely, use a 100-watt block for a model that is enough 65 watts.
Case 1: Adapter power is less than recommended
- ⚡ Slow charging: the laptop will charge longer, and at high load (games, rendering) the battery may even run out.
- 🔋 Adapter overheating: Power supply will work at the limit of possibilities, which reduces its service life.
- ⚠️ Port Damage Risk: If the Adapter Does Not Support the Protocol USB Power Delivery (PD), There may be overloading of the power controller.
Case 2: Adapter power is more than recommended
It's simpler here: modern Xiaomi laptops automatically limit power consumption. For example, if you connect a 100-watt adapter to a RedmiBook 14 (65 W), the laptop will only take the 65 W it needs.
- 💰 Overpayment: more powerful adapters are more expensive, and they will not be useful.
- 🔌 Dimensions: 100-watt blocks are usually larger and heavier than 65-watt blocks.
- ⚡ Compatibility: Some ultrabooks (such as Mi Notebook Air) may not support adapters over 45W.
💡
If you work on the road often, choose an adapter with a power reserve of 20-30% above the standard, which will speed up charging and reduce the heating of the power supply.
How to determine the power of the charger for your model?
The most reliable way is to look at the adapter sticker or in the laptop documentation. But what if you're a Lost power supply or you're buying a used laptop? Here are 4 proven methods:
- Check the model on the official website: go to your model page on mi.com → section "Specifications" → "Power Adapter".
- Use of Xiaomi Power Manager (for Windows): the program shows the current charging power and recommended parameters.
- Label analysis on laptop: usually under the keyboard or on the bottom cover is Input: 19.5V == 3.33A (That's 65 watts).
- Search by serial number: enter SN on order.mi.com - the characteristics will indicate the power of the adapter.
If none of the methods worked, use our compatibility table (see section above) or ask a question in the official Xiaomi chat.
What if the laptop is not charged from the original adapter?
Can I use chargers from other brands?
Xiaomi laptops (except gaming lines) support the standard. USB Power Delivery (PD), Therefore, in theory, you can use adapters from Apple, Dell, Lenovo or universal. PD-The main conditions:

| Anker 735 (Nano II 65W) | 65 W. | All models with USB-C | 18 months warranty |
| Xiaomi MDY-12-EP 100W | 100 W. | Mi Notebook Pro, RedmiBook Pro | The original adapter |
⚠️ Warning: Don't use cheap, uncertified adapters, which can damage the laptop's power controller, especially Mi Gaming's gaming models, which require high voltage stability.
Features of charging gaming laptops Xiaomi
Xiaomi Mi Gaming gaming laptops are a separate story, and come with 180 to 240 watts of proprietary adapters with a unique connector (not USB-C!).
- 🎮 Dual adapters: Some models (e.g. Mi Gaming Laptop 2021) come with two power units (120W each) for load distribution.
- ⚡ High voltage: standard voltage — 19.5V/12A (230 W), whereas office models — 20V/3.25A (65 Watt).
- ⚠️ Impossibility of replacing USB-C: high-power ports USB-C not used for charging.

Frequent errors when choosing a charger
Even the most experienced users sometimes make the mistake of buying an adapter. TOP-5 Mistakes that can lead to problems:
- Ignoring USB-C: Not all USB-C ports support charging. For example, RedmiBook 14 2020 has USB-C, but charging only goes through the left port.
- Buying a “universal” adapter: cheap Chinese blocks often don’t match the claimed characteristics.
- Ignoring regional features: adapters for the Chinese market may not be suitable for Russian outlets (different plugs and voltages).
- Smartphone cable use: Phone cables are not designed for high currents (insulation can melt).
- Neglecting BIOS updates: Newer firmware versions sometimes add support for more powerful adapters.
To avoid errors, always check the official specifications and feedback from other users on the forums (e.g. 4PDA or MIUI SU).
💡
For Xiaomi laptops with USB-C, adapters with PD 3.1 support and 20 percent higher than standard power are the best choice, providing fast charging and margin for future updates.
