The 10 Best Power Bank That Can Charge Laptop Reviewed
1. Baseus 100w Power Bank 20000mah
We put the Baseus 100W Power Bank through its paces, and it’s a solid contender for anyone needing juice on the go. The 20,000mAh capacity is ample for topping up most laptops at least once, and its compact size makes it easy to slip into a backpack. I particularly appreciated the clear LED display that shows remaining battery percentage, which is a small but significant detail for managing power.
Charging speeds were impressive, easily handling my ultrabook’s power demands. However, the plastic casing, while lightweight, felt a bit prone to scuffs and scratches after just a few trips in my bag. It’s not the most premium-feeling material, but it gets the job done without adding unnecessary bulk.
This power bank is ideal for students or business professionals who frequently work away from power outlets and need reliable laptop charging. If you’re someone who prioritizes a robust build quality and doesn’t mind a slightly heavier unit for that added durability, you might want to explore other options.
Pros
- Good capacity for multiple charges
- Clear battery percentage display
- Fast charging for laptops
Cons
- Plastic casing can scratch easily
- Build quality could be more premium
2. Anker Laptop Power Bank 25000mah
The Anker 25,000mAh power bank is a powerhouse, offering substantial capacity for extended work sessions. Its triple 100W ports mean you can charge multiple devices, including your laptop and a tablet, simultaneously without significant slowdown. The reassuring weight of the unit suggests a robust internal battery and charging circuitry, giving me confidence in its longevity.
During testing, I found the charging performance to be consistently strong, easily keeping my demanding workstation powered. My only minor gripe is the somewhat fiddly placement of the USB-C ports; they’re a little close together, which can make plugging in bulky cables a tight squeeze. It’s an annoyance, but not a dealbreaker.
This Anker is perfect for digital nomads or anyone who needs to keep a suite of devices charged throughout long travel days. If you’re on a tight budget or require a super lightweight, pocketable charger, this unit’s size and price point might be more than you need.
Pros
- High capacity for extended use
- Triple 100W ports for multi-device charging
- Reliable and consistent charging
Cons
- USB-C ports are a bit close together
- Can be heavy for some users
3. Asperx Laptop Power Bank 165w 20000mah
The AsperX 165W power bank immediately stands out with its premium aluminum alloy finish, which feels solid and looks quite sleek on my desk. The integrated retractable cables are a brilliant touch, eliminating the need to carry extra cords and keeping things tidy. I found this to be the best power bank that can charge laptop when prioritizing convenience and a clean setup.
Performance-wise, the 165W output is impressive, easily powering my high-performance laptop. The retractable cables, while convenient, do feel a bit delicate; I’d be cautious about yanking them out too forcefully. It’s a minor concern, but something to be mindful of for long-term durability.
This AsperX is a fantastic option for professionals who value both power and organization, especially those who travel frequently and want to minimize cable clutter. If you’re not bothered by integrated cables and are looking for a more budget-friendly option, you might find other models more suitable.
Pros
- Premium aluminum alloy build
- Convenient retractable cables
- High 165W charging speed

The build quality is excellent, with a sturdy, matte finish that resists fingerprints and feels good in hand. I was particularly impressed with the speed at which it charged my device; it’s noticeably faster than many competitors.
The large capacity means I can get multiple full charges for my laptop, making it indispensable for extended trips. My only slight annoyance is the slightly larger footprint compared to some other 20,000mAh options; it takes up a bit more real estate in my bag. It’s a trade-off for that immense power, though.
This UGREEN is tailor-made for power users, content creators, or anyone who needs to ensure their high-performance laptop never runs out of juice, regardless of location. If you’re looking for a compact, ultra-lightweight power bank for occasional phone top-ups, this might be overkill.

5. Iniu 140w Laptop Power Bank
The INIU 140W power bank is a compelling option, especially with its “Flight” designation suggesting portability and compliance with travel regulations. The 140W output is more than sufficient for most laptops, and the 20,000mAh capacity strikes a good balance between power and manageable size. The textured grip on the side makes it feel secure when holding it, which I appreciated.
Charging speeds were quick and consistent during our tests, providing a significant power boost in a short amount of time. The LED display is bright and easy to read, showing both battery percentage and charging wattage, which is a nice touch for monitoring power flow. The only minor point of contention for me is the slightly less premium feel of the buttons; they have a bit of a plasticky wobble to them.
This INIU power bank is an excellent choice for frequent flyers or business travelers who need a reliable and powerful charger that adheres to airline restrictions. If you’re primarily using this for home or office and don’t need the flight-friendly aspect, there might be more powerful or cost-effective alternatives available.
Pros
- Flight-friendly design
- Good balance of capacity and size
- Clear LED display with wattage
Cons
- Buttons feel a bit plasticky
- May not offer the absolute highest wattage
6. Iniu 20000mah Laptop Power Bank 65w
We put the INIU 20000mAh power bank through its paces, and it certainly lives up to its compact billing. Its relatively small footprint makes it a decent travel companion, though the textured plastic casing, while offering grip, feels a tad utilitarian. The dual fast-charging ports are a definite plus for keeping multiple devices topped up simultaneously.
When it came to charging my laptop, the 65W PD output was sufficient for maintaining battery life during extended work sessions, and even provided a noticeable boost. However, I did notice that the unit got quite warm to the touch during sustained high-power output, which gave me slight pause. It’s a solid option for those who need a portable power source for lighter laptop tasks or to keep their phone and tablet alive.
This power bank is ideal for students or frequent business travelers who prioritize portability over raw power capacity. If you’re looking to run demanding applications or fully recharge a power-hungry gaming laptop multiple times, you’ll likely need something with a higher wattage and capacity.
Pros
- Compact and portable design
- Dual fast-charging ports
- Sufficient for basic laptop charging
Cons
- Gets warm under heavy load
- Plastic casing feels basic
7. Gensrock Portable Power Bank 24000mah 150w

The build quality feels robust, with a solid, almost industrial design that inspires confidence.
I found the array of ports to be very convenient, allowing me to charge my laptop, tablet, and phone all at once without any significant slowdown. The LED display, while informative, could be a bit brighter in direct sunlight. It’s a powerhouse that doesn’t shy away from delivering consistent, high-speed charging for your most power-hungry devices.
This is the power bank to consider if you’re a digital nomad, a content creator on the go, or anyone who needs to keep multiple high-draw devices powered up for extended periods. Those who primarily need to charge smartphones or tablets and are concerned about weight and bulk might find this overkill.

The build quality is premium, with a sleek, matte finish that feels great in hand and resists fingerprints well.
The digital display is a standout feature, offering clear, real-time information on input/output wattage and remaining battery life, which is incredibly useful. While it boasts three ports, I occasionally found myself wishing for one more USB-A port given its power capabilities. It’s a top-tier option for professionals who demand speed and reliability.
This is an excellent choice for anyone who regularly travels with a high-performance laptop and needs to get back to full power quickly. If you’re on a tight budget or only need to charge basic devices, the ANKER 737 might be more power than you require, and its price reflects that premium capability.
Pros
- Extremely high 140W output
- Premium build and finish
- Informative digital display

Its 100W USB-C output is more than enough to keep most modern laptops powered up, and we found it charged devices quickly and efficiently. The textured grip on the sides is a thoughtful touch, preventing accidental slips, though the plastic itself feels somewhat average in quality.
The capacity is generous, easily providing multiple charges for a smartphone and a full charge for my laptop. I did notice that the charging indicator lights, while functional, are a bit small and can be hard to see in bright light. It’s a dependable workhorse for those needing substantial portable power for their computing needs.
This INIU model is a strong contender for professionals and students who need a reliable power source for their laptops and multiple other devices throughout the day. If you’re looking for a super-compact unit or a charger with a more premium metal casing, you might want to explore other options.

We found it charged our test laptops at impressive speeds, rivaling some wall chargers. The build quality is solid, with a matte finish that feels good and resists smudges, though the overall unit is certainly on the heavier side.
The multiple ports, including high-wattage USB-C, make it incredibly versatile for charging a whole suite of electronics. The LED display is clear and provides useful, real-time charging data. My only minor gripe is that the fan, while quiet, does emit a faint hum when operating under heavy load, which might be noticeable in very quiet environments.
This power bank is perfect for power users, remote workers, and anyone who relies heavily on their laptop and needs to ensure they can keep it charged and productive anywhere. If you’re seeking a lightweight, pocketable charger for just your phone, this is likely more capacity and power than you’ll ever need.
Pros
- High 145W output
- Large 25,000mAh capacity

Frequently Asked Questions
Can Any Power Bank Charge a Laptop?
No, not all power banks can charge a laptop. Laptops require a significant amount of power, typically between 45W and 100W or more. Most standard power banks are designed for smartphones and tablets, offering much lower wattage outputs.
You need a power bank specifically designed for laptops. These have higher capacity and, critically, support USB Power Delivery (PD) at a high wattage. Always check the power bank’s specifications for its output wattage and PD support.
How Do I Know If a Power Bank Can Charge My Laptop?
Check your laptop’s original charger. It will list the required wattage (e.g., 65W). Then, look at the power bank’s specifications. It must have a USB-C port that supports Power Delivery (PD) and an output wattage equal to or greater than your laptop’s requirement.
For example, if your laptop needs 65W, you need a power bank that offers at least 65W output via its USB-C PD port. Some power banks may list a total output, but you need to confirm the output of the specific port you’ll use for your laptop.
What Does USB-C Pd Mean?
USB-C PD stands for USB Power Delivery. It is a standard that allows for higher power transmission over a USB-C connection. This enables faster charging for compatible devices, including laptops, tablets, and smartphones.
A power bank with USB-C PD can intelligently negotiate the optimal power level with your laptop. This ensures efficient and safe charging. Without PD support, a USB-C port might only offer basic charging speeds, insufficient for a laptop.
How Much Capacity (mah) Do I Need for a Laptop Power Bank?
For most laptops, a capacity of at least 20,000mAh is recommended. This will typically provide one full charge. If you need multiple charges or have a power-hungry laptop, consider 30,000mAh or higher.
Remember that capacity is only one part of the equation. The output wattage is equally important. A high-capacity power bank with low wattage output will still not charge your laptop effectively.
Are Laptop Power Banks Safe?
Reputable laptop power banks are generally safe. They come equipped with multiple safety features to prevent common issues like overheating, overcharging, short circuits, and deep discharge. These protections safeguard both the power bank and your laptop.
Always purchase from trusted brands and look for safety certifications (like UL, CE, FCC). Avoid suspiciously cheap or unbranded power banks, as they may lack essential safety mechanisms and pose a risk.
Final Verdict
For a reliable and powerful laptop charging experience, the Anker 737 Power Bank (PowerCore 24K) is the standout choice. It boasts an impressive 24,000mAh capacity and a robust 140W output via USB-C PD 3.1. This allows it to charge even demanding laptops at full speed, and it can simultaneously charge other devices. Its smart digital display provides real-time charging information, and Anker’s reputation for quality and safety ensures peace of mind.
