The Mi Power Bank can charge laptops that support USB-C Power Delivery with sufficient wattage output, but not all models are compatible.
Understanding Mi Power Bank’s Laptop Charging Capability
The Mi Power Bank has become a popular choice for portable charging, offering a sleek design and solid capacity. But the big question remains: Can Mi Power Bank charge laptop? The answer isn’t a simple yes or no—it depends on several factors including the model of the power bank, the laptop’s charging requirements, and the connection type.
Mi offers various power banks with different capacities and output specifications. Some models come equipped with USB-C ports that support Power Delivery (PD), a fast-charging technology capable of delivering higher wattage to devices like laptops. However, older or lower-capacity Mi power banks may only support standard USB outputs, which are insufficient for laptop charging.
Laptops generally require higher voltage and current than smartphones or tablets. Most modern laptops need at least 30W to 65W of power for efficient charging. If the Mi power bank can deliver this through its USB-C PD port, it can charge compatible laptops effectively. Otherwise, it will either charge very slowly or not at all.
Key Features of Mi Power Banks Relevant to Laptop Charging
Mi Power Banks come in various capacities ranging from 10,000mAh to 20,000mAh or more. The features affecting laptop charging include:
- USB-C Power Delivery (PD): Enables fast charging and higher wattage output up to 45W or more on some models.
- Output Ports: Multiple USB-A and USB-C ports allow simultaneous device charging but only certain ports support laptop-level power.
- Capacity: Larger capacity means more total energy stored but doesn’t guarantee laptop compatibility without proper output specs.
- Voltage and Current Ratings: These determine if the power bank can meet the laptop’s charging needs effectively.
For example, the Mi 20,000mAh Power Bank 3 Pro features a USB-C port delivering up to 45W via PD, enough for many ultrabooks and MacBooks. In contrast, smaller models with only 18W output won’t reliably charge most laptops.
The Role of USB-C Power Delivery in Laptop Charging
USB-C PD is a game-changer for portable chargers. It allows dynamic voltage adjustment between devices and chargers, enabling higher wattage delivery safely. This flexibility is crucial for powering laptops since they demand more juice than phones.
Mi’s high-end power banks supporting PD can provide:
- 5V at 3A (15W)
- 9V at 3A (27W)
- 12V at 3A (36W)
- 15V at 3A (45W)
- 20V at 2.25A (45W)
These voltage levels align well with many modern laptops’ requirements. Without PD support, most power banks max out around 10-18W on USB-A ports — insufficient for laptop charging.
Laptop Compatibility Based on Charging Wattage
Different laptops have varying minimum wattage needs:
- Ultrabooks and MacBook Air: Usually require around 30-45W.
- MacBook Pro and gaming laptops: Demand between 60-100W or more.
- Older laptops with barrel connectors: Often incompatible with USB-C chargers unless using adapters.
So even if a Mi power bank supports PD at 45W, it won’t fully charge high-end gaming laptops needing over 60W. It will work best with mid-range ultrabooks or smaller notebooks.
The Importance of Cable Quality and Connection Type
Even if your Mi Power Bank supports sufficient wattage output via USB-C PD, the cable connecting your devices plays a critical role. Poor quality or non-PD-certified cables can limit current flow and reduce charging speed dramatically.
To maximize laptop charging:
- Use certified USB-C PD cables: These cables handle higher voltages safely without overheating.
- Avoid cheap or damaged cables: They may cause intermittent connections or slow charging.
- If using adapters: Ensure they support PD passthrough; otherwise, you risk damaging your devices or losing efficiency.
Many users overlook this aspect and blame the power bank when their laptop charges slowly or not at all.

Frequently Asked Questions
Can Mi Power Bank Charge Laptop Models with USB-C Power Delivery?
Yes, Mi Power Banks that support USB-C Power Delivery (PD) can charge laptops compatible with PD technology. These power banks provide sufficient wattage, typically up to 45W, to power many ultrabooks and MacBooks efficiently.
Can Mi Power Bank Charge Laptop Without USB-C PD Support?
No, Mi Power Banks without USB-C PD usually cannot charge laptops effectively. Standard USB outputs deliver lower wattage, which is insufficient for most laptops and may result in very slow charging or no charge at all.
Can Mi Power Bank Charge Laptop Models Requiring More Than 45W?
Mi Power Banks generally offer up to 45W output via USB-C PD. Laptops requiring more than this wattage may not charge properly or will charge slowly. It’s important to check your laptop’s power requirements before relying on a Mi Power Bank.
Can Mi Power Bank Charge Laptop While Charging Other Devices?
Some Mi Power Banks have multiple output ports allowing simultaneous charging of several devices. However, when charging a laptop and other devices at the same time, the total power output is shared, which might reduce the laptop’s charging speed.
Can Mi Power Bank Charge Laptop for Extended Periods on a Single Charge?
The ability to charge a laptop for extended periods depends on the power bank’s capacity. High-capacity models (e.g., 20,000mAh) can provide multiple charges or longer usage time, but smaller capacity models will deplete faster when powering laptops.
The Practical Experience: Charging Laptops With Mi Power Banks in Real Life
Many users report that their Xiaomi Mi Power Bank charges smartphones and tablets flawlessly but struggle with laptops unless they own a model like the “Power Bank 3 Pro.” The reasons include:
- Lack of sufficient wattage: Most mid-range power banks don’t hit the threshold required by laptops.
- Laptop battery management systems: Some laptops refuse to charge from low-wattage sources as a safety measure.
- Cable incompatibility: Non-PD cables reduce effective wattage delivery drastically.
- Lack of firmware optimization: Some older power banks don’t negotiate voltage properly with newer laptops using advanced PD protocols.
- Laptop usage during charging: Heavy tasks consume more energy than what low-output power banks provide causing net battery drain despite being plugged in.
- Select the correct port: Use only the dedicated USB-C PD port labeled on your device.
- Tighten cable connections: Loose plugs cause intermittent connections reducing efficiency.
- Avoid heavy workload during charging:If possible shut down CPU-intensive apps while plugged in for faster battery gain.
- Keeps firmware updated:Xiaomi occasionally releases updates improving device compatibility—check official sources regularly.
- Avoid daisy chaining adapters/cables:This often causes voltage drops harmful to stable laptop charging performance.
- Laptops requiring>45 watts won’t fully charge from any standard Xiaomi power bank currently available since none exceed that output level officially.
- Laptops without native USB-C charging ports cannot be charged directly unless specialized adapters are used—but these often cause compatibility headaches and potential damage risks if mismatched voltage occurs.
- If your model lacks any form of USB-C PD support—like many Redmi variants—you’re essentially limited to phone/tablet charging speeds unsuitable for laptops.
This means even if your power bank technically outputs some voltage through USB-C port without full compatibility it might not actually increase your battery percentage significantly.
Troubleshooting Tips For Better Laptop Charging With Mi Power Banks
If you already own a compatible model but face issues:
The Limits: When Can’t Mi Power Bank Charge Laptop?
Despite its strengths, there are clear limitations:
This means heavy-duty gaming rigs or professional mobile workstations need dedicated chargers rather than relying solely on portable power banks like those from Xiaomi.
The Bottom Line – Can Mi Power Bank Charge Laptop?
The simple truth is yes—but only under specific conditions. If you have one of Xiaomi’s latest high-capacity models featuring true USB-C Power Delivery up to around 45 watts—like the Xiaomi Mi Power Bank 3 Pro—you can confidently use it as a portable charger for many modern ultrabooks and MacBooks.
However, if your model lacks proper PD support or your laptop demands higher wattage above what these banks supply—charging will be slow at best or fail altogether.
Using quality certified cables is non-negotiable here because even the best hardware falters without proper data/power transmission lines.
In summary: You need both compatible hardware (high-wattage PD-capable bank) plus matching software protocols (laptop accepting USB-PD input) along with good cables to make this work smoothly.
