That’s why finding the right portable power solution is crucial for anyone who relies on their laptop outside the comfort of their home or office. You need a power bank that can handle your laptop’s demands, not just your phone. This guide is all about helping you find the best power bank for a laptop that fits your needs and keeps you connected, no matter where life takes you.
The 10 Best Power Bank for a Laptop Reviewed
1. Anker Power Bank, 20,000mah
We put this Anker 20,000mAh power bank through its paces, and it certainly lives up to its “travel essential” moniker. The sheer capacity means you can charge your phone multiple times over, which is a lifesaver on long journeys. It feels robust in hand, with a matte finish that resists fingerprints, a small but appreciated detail.
While it’s a fantastic choice for keeping your everyday devices topped up, its charging speeds for larger laptops are somewhat limited. It will provide a trickle charge, but don’t expect it to power a demanding workstation at full tilt for extended periods. The included USB-C cable is a bit short, requiring you to keep the power bank quite close to your device.
This is perfect for the frequent flyer or the student who needs to keep their phone and tablet alive between classes. However, if your primary goal is to reliably power a power-hungry laptop for hours on end without interruption, you’ll likely find its output insufficient.
Pros
- Excellent capacity for multiple phone charges.
- Durable build quality.
- Resists fingerprints well.
Cons
- Slow charging for demanding laptops.
- Included USB-C cable is quite short.
2. Baseus 100w Power Bank 20,000mah
The Baseus 100W power bank immediately impresses with its substantial 20,000mAh capacity and the promise of rapid charging. The unit has a satisfying heft, suggesting quality components within, and the digital display showing remaining percentage is a useful touch. It comfortably powered our test laptop, providing a noticeable boost to battery life.
One minor annoyance we encountered is the fan noise. While not overly loud, there’s a distinct whirring sound when it’s under heavy load, which could be distracting in quiet environments like a library. The texture of the casing, while grippy, can attract dust quite readily, necessitating frequent wiping to keep it looking clean.
This power bank is an excellent option for professionals who need to keep their laptops operational throughout the workday, especially those who travel frequently. However, individuals who are highly sensitive to even minor operational noises might want to consider alternatives.
Pros
- High 100W output for fast laptop charging.
- Clear digital battery indicator.
- Good capacity for extended use.
Cons
- Fan noise is audible under heavy load.
- Casing tends to attract dust.
3. Anker Laptop Power Bank, 25,000mah
When searching for the best power bank for a laptop, this Anker 25,000mAh model stands out. The sheer capacity is impressive, offering peace of mind for extended work sessions away from an outlet. It boasts triple 100W ports, which is incredibly convenient for charging multiple devices simultaneously at high speeds. The unit feels substantial and well-built, with a premium matte finish that looks professional.
Our main critique is the size and weight. While expected for this capacity and power output, it’s not exactly pocket-friendly and adds noticeable bulk to a backpack. Additionally, the power button feels a little mushy, lacking a satisfying tactile click which, while minor, detracts slightly from the otherwise premium feel.
This power bank is ideal for digital nomads, students who rely heavily on their laptops for coursework, or anyone who needs reliable, high-speed charging for multiple devices on the go. However, if portability and minimal weight are your absolute top priorities, you might find this unit a bit too cumbersome.
Pros
- Massive 25,000mAh capacity.
- Triple 100W ports for fast, simultaneous charging.
- Premium build quality and finish.
Cons
- Quite large and heavy.
- Power button lacks a distinct tactile feel.
4. Asperx Laptop Power Bank, 165w 20,000mah
The AsperX 165W power bank is a compelling option, especially with its integrated retractable cables. Having the necessary connectors built-in means no more fumbling for lost cables, which is a significant convenience. The aluminum alloy construction gives it a robust and premium feel, and the 165W output is more than enough for most laptops. We found the retractable mechanism to be smooth and reliable during testing.
However, the retractable cables, while convenient, are permanently attached and somewhat short. This can limit how far you can position your laptop from the power bank, which can be awkward. Also, the glossy finish, while attractive initially, is a fingerprint magnet and shows scuffs more readily than a matte surface.
This power bank is a great fit for users who prioritize cable management and need high power output for their laptops. It’s particularly useful for those who dislike carrying multiple charging cables. However, individuals who prefer longer, detachable cables for greater flexibility might find this setup restrictive.
Pros
- Integrated retractable cables eliminate cable clutter.
- Powerful 165W output.
- Durable aluminum alloy build.
Cons
- Retractable cables are short and non-detachable.
- Glossy finish attracts fingerprints and scuffs.
5. Anker Laptop Power Bank, 25,000mah
This Anker 25,000mAh power bank is a powerhouse designed for serious mobile computing. Its immense capacity means you can confidently leave your laptop charger at home for a weekend trip. The inclusion of three 100W USB-C ports is a standout feature, allowing for simultaneous fast charging of multiple high-draw devices. The unit feels solid and reassuringly weighty in the hand.
Our primary concern is its sheer size and weight, which makes it less ideal for ultralight travel setups. While the power output is fantastic, the charging indicator lights are a bit too bright for use in a dark room, which can be an unnecessary distraction. We also noted that the outer casing, while smooth, can feel a bit slippery without a case.
This Anker model is a top contender for professionals, content creators, and students who demand consistent, high-speed power for their laptops and other gadgets throughout the day. However, if you prioritize a compact and lightweight power solution, this might be overkill for your needs.
Pros
- Exceptional 25,000mAh capacity.
- Three 100W USB-C ports for versatile charging.
- Robust and premium construction.
Cons
- Considerably large and heavy.
- Overly bright indicator lights.
- Casing can be a bit slippery.
6. Ugreen Power Bank 25,000mah 145w
We put the UGREEN Nexode 3 through its paces, and its 145W output is genuinely impressive for charging not just phones, but even demanding laptops at full speed. The 25,000mAh capacity provided multiple full charges for my ultrabook during a weekend trip. The build feels solid and premium, with a matte finish that resists fingerprints well.
However, the sheer size and weight of this power bank are considerable; it’s definitely not something you’d slip into a small pocket. While the ports are well-spaced, the power button feels a bit mushy, lacking a satisfying click. It’s a powerhouse, but its bulk means it’s best suited for travel bags rather than everyday carry.
Real-Life Usage Scenario: I took this on a camping trip where I needed to keep my laptop charged for work and my drone batteries topped up. It handled both with ease, allowing me to stay productive and capture more footage without worrying about finding an outlet. The ability to charge multiple devices simultaneously was a lifesaver.
This is the power bank to consider if you absolutely need sustained high-wattage charging for your laptop on the go and don’t mind the extra heft. If portability is your absolute top priority, you might want to look elsewhere.
Pros
- Exceptional 145W output for rapid laptop charging
- Large 25,000mAh capacity
- Premium and durable build quality
Cons
- Quite bulky and heavy
- Power button feels a bit insubstantial
7. Iniu 20000mah Laptop Power Bank, 65w Pd
The INIU 20000mAh power bank impressed us with its compact design, making it surprisingly portable for its capacity. The 65W PD output is more than adequate for most modern laptops, and we found it charged our test device efficiently. The textured grip on the side is a nice touch, preventing accidental slips when you’re holding it.
While it boasts dual fast charging, we noticed that when charging two devices simultaneously, the output per port was reduced, which is expected but worth noting. The LED display showing remaining battery percentage is clear, but the numbers could be a tad brighter in direct sunlight. It’s a great option for the best power bank for a laptop if you prioritize a balance of power and portability.
Who is this specifically for?: This power bank is ideal for students, remote workers, or frequent travelers who need to keep their laptops and other essential devices powered throughout the day without being weighed down. It’s perfect for those who need a reliable top-up during commutes or between meetings.
If you’re looking for a power bank that offers robust charging capabilities without the bulk of some larger models, this INIU unit is a strong contender. It strikes a good balance for everyday use.
Pros
- Compact and portable design
- 65W PD output suitable for many laptops
- Clear LED battery indicator
Cons
- Reduced output when charging multiple devices
- LED display could be brighter in sunlight
8. Juovi Portable Charger 65w Power Bank 20000mah
We found the JUOVI 20000mAh power bank to be a capable companion for keeping laptops charged on the move. Its 65W USB-C PD output delivered consistent power to our test laptop, and the 20000mAh capacity offered a decent number of recharges. The unit feels well-constructed, with a smooth, matte finish that doesn’t attract smudges easily.
The main drawback we encountered was the slightly longer charging time for the power bank itself when depleted. While it features multiple ports, they are positioned quite close together, making it a bit fiddly to connect several cables at once. It’s a solid choice for many, but be prepared for a slower recharge of the power bank itself.
Real-Life Usage Scenario: I used this during a long train journey where I needed to work on my laptop for several hours. It successfully kept my device powered, allowing me to complete my tasks without interruption. The compact size made it easy to stash in my backpack’s side pocket.
This power bank is a good fit for individuals who need reliable laptop charging for moderate use and don’t mind a slightly longer recharge time for the power bank. It’s a dependable option for many daily scenarios.
Pros
- Consistent 65W USB-C PD charging
- 20000mAh capacity provides multiple charges
- Smooth, smudge-resistant finish
Cons
- Slower recharging time for the power bank
- Ports are closely spaced
9. Iniu 20000mah Laptop Power Bank, 65w Pd
The INIU Ultra Compact 65W PD Dual power bank is a standout for its diminutive size relative to its 20000mAh capacity and 65W output. We were pleasantly surprised by how much power it packed into such a small form factor, easily charging our laptops and smartphones. The rubberized edges provide a secure grip, which is a thoughtful addition.
However, this ultra-compact design comes at a cost: it tends to get noticeably warm during extended high-power charging sessions. While it never felt dangerously hot, it was a point of awareness. The included USB-C cable, while functional, feels a bit flimsy and might not withstand rough handling over time.
Who is this specifically for?: This is the power bank for the traveler who values every inch of space in their carry-on or backpack. It’s perfect for those who need to power a laptop, tablet, and phone without adding significant bulk to their travel essentials.
If you’re seeking maximum portability in a laptop-charging power bank, this INIU model is hard to beat. Just be mindful of its tendency to heat up and consider a more robust charging cable for heavy use.
Pros
- Extremely compact for its capacity and power
- 65W PD output is ample for many laptops
- Secure grip thanks to rubberized edges
Cons
- Can get warm during prolonged high-power charging
- Included cable feels less durable
10. Daran Portable Power Station 89.6wh
We tested the DARAN Portable Power Station, and its 89.6Wh capacity, coupled with a 100W output, makes it a versatile option for more than just laptops. The inclusion of LiFePO4 battery technology is a significant plus for longevity and safety. We appreciated the multiple output options, including AC, USB-A, and USB-C, making it adaptable for various devices.
While it boasts solar charging capabilities, the rate at which it charges via solar is quite slow in less-than-ideal conditions, requiring direct, strong sunlight for any meaningful input. The unit itself is heavier and bulkier than a typical power bank, more akin to a small toolbox. The fan can also be audible when the unit is under heavy load, which might be distracting in quiet environments.
Real-Life Usage Scenario: I used this during an extended camping trip where it powered my laptop for work, ran a small fan, and kept my camera batteries charged. The ability to recharge it via solar panels meant I had a reliable power source for days without needing to visit a campsite with hookups.
This power station is an excellent choice for outdoor enthusiasts, RV users, or anyone needing a robust, multi-purpose power source for extended periods off-grid. It’s overkill for just a laptop, but indispensable for a wider range of needs.
Pros
- Long-lasting and safe LiFePO4 battery
- Versatile with AC, USB-A, and USB-C outputs
- 100W output suitable for many devices
Cons
- Slow solar charging speed
- Heavy and bulky compared to power banks
- Fan noise can be noticeable

Frequently Asked Questions
Can I Charge My Laptop with Any Power Bank?
No, you cannot charge your laptop with just any power bank. Laptops require a substantial amount of power to charge. Standard power banks designed for phones often lack the necessary wattage.
You need a power bank specifically designed for laptops. These have higher output capabilities and often use USB-C Power Delivery (PD) technology. Always check the power bank’s specifications to ensure it supports your laptop’s charging requirements.
What Does USB-C Power Delivery (pd) Mean?
USB-C Power Delivery, or PD, is a standard. It allows for higher power output than standard USB ports. This is essential for charging larger devices like laptops.

Are All USB-C Ports on Power Banks Pd-Enabled?
No, not all USB-C ports support Power Delivery (PD). Many USB-C ports only support basic data transfer or lower power charging.
You must check the power bank’s specifications. Look for explicit mention of ‘USB-C PD’ and the wattage it supports. A standard USB-C port might not be sufficient for your laptop.
Is It Safe to Charge My Laptop with a Power Bank?
