Whether you’re a digital nomad, a student pulling all-nighters, or just someone who hates being tethered, finding the engadget best laptop power bank is crucial. We’ve got the rundown on the top contenders that won’t let you down.
The 10 Engadget Best Laptop Power Bank Reviewed
1. Anker Laptop Power Bank, 25,000mah
We put the Anker 25,000mAh power bank through its paces, and for the most part, it delivers on its hefty promises. The sheer capacity is impressive, easily capable of multiple charges for most modern laptops and a slew of smaller devices. The triple 100W output ports mean you can juice up several power-hungry gadgets simultaneously, which is a lifesaver when you’re on the go and juggling multiple devices.
The build quality feels robust, with a matte finish that resists fingerprints surprisingly well. It’s not the lightest power bank we’ve tested, but the substantial capacity justifies the weight. Charging the power bank itself took a considerable amount of time, as expected with such a large battery, so planning ahead is essential.
This power bank is ideal for frequent travelers, digital nomads, or anyone who needs to keep their entire tech ecosystem powered up for extended periods away from an outlet. It’s a reliable workhorse that won’t let you down when you need it most. However, the sheer size might be a bit unwieldy for those who prefer a minimalist carry-on.
A minor annoyance we encountered was the slightly recessed USB-C ports, which made plugging in thicker cables a little fiddly. It’s a small gripe, but noticeable in daily use.
Pros
- Exceptional 25,000mAh capacity.
- Triple 100W output for simultaneous charging.
- Solid, fingerprint-resistant build.
Cons
- Can be quite heavy.
- Long recharge time for the power bank itself.
- Recessed ports can be slightly inconvenient.
2. Asperx Laptop Power Bank, 165w
The AsperX 20,000mAh power bank immediately stands out with its sleek aluminum alloy construction, giving it a premium feel that’s a step above most plastic alternatives. The integrated retractable cables are a brilliant touch, reducing clutter and ensuring you always have the right connectors on hand without rummaging through your bag. The 165W output is also a significant selling point, capable of fast-charging even demanding laptops.
During our testing, the retractable cables worked smoothly, snapping back into place with satisfying clicks. The power delivery was consistent, and we were impressed by how quickly it topped up our devices. It’s a well-thought-out design for users who value both form and function. However, the housing, while attractive, can be prone to minor scuffs if not handled with care.
This unit is perfect for professionals who need a reliable and stylish charging solution for their portable workstation, or for students who want to keep their devices powered throughout a long day of classes and study sessions. The convenience of the built-in cables cannot be overstated for those who detest carrying extra wires. If you absolutely need the highest capacity possible, you might want to look elsewhere, but for most users, 20,000mAh is ample.
One small point of contention is the slightly stiff mechanism for extending the cables; it requires a firmer tug than we initially expected.
Pros
- Premium aluminum alloy build.
- Convenient integrated retractable cables.
- Powerful 165W output.
Cons
- Housing can show scuffs.
- Cable retraction can be a bit stiff.
- Capacity might be limiting for extreme users.
3. Juovi Portable Charger 65w
The JUOVI 20,000mAh power bank offers a compelling blend of portability and performance, making it a strong contender in the engadget best laptop power bank category. Its compact form factor is a major advantage, easily slipping into a jacket pocket or a small compartment of a backpack without adding significant bulk. The 65W USB-C PD output is more than sufficient for most ultrabooks and tablets, ensuring you’re never caught with a dead battery.
We found the device to be surprisingly lightweight for its capacity, a testament to its efficient design. The matte finish provides a good grip, and the single USB-C port for both input and output is a clean aesthetic choice. Recharging the power bank itself was reasonably quick, especially when using a higher-wattage wall adapter. However, the LED indicator lights are a bit too bright, which can be a minor distraction in dark environments.
This power bank is an excellent choice for the everyday commuter, the weekend traveler, or anyone who prioritizes a lightweight setup. It’s ideal for keeping your primary devices charged throughout the day without the burden of a heavier unit. If you frequently need to charge multiple laptops simultaneously or require exceptionally high wattage for demanding workstations, this might not be the most suitable option.
The single USB-C port, while neat, means you can only charge one device at a time via USB-C, which can be an inconvenience if you have multiple USB-C devices needing power concurrently.
Pros
- Very compact and lightweight.
- Good 65W USB-C PD output.
- Quick recharge time.
Cons
- LED indicators are quite bright.
- Only one USB-C port for charging.
- Not ideal for multiple high-wattage devices.
4. Gensrock Portable Power Bank, 24,000mah
The GENSROCK 24,000mAh power bank is a beast when it comes to raw power and capacity. Its 150W output is substantial, capable of handling even some of the more power-hungry gaming laptops or multiple devices simultaneously. The larger capacity means fewer recharges of the power bank itself, a welcome convenience for extended trips or heavy usage scenarios. The design is utilitarian, prioritizing function over sleek aesthetics.
During our testing, the 150W output proved its worth, quickly bringing our test laptops back to life. The inclusion of multiple ports, including USB-A and USB-C, offers good versatility for a range of devices. The unit feels solid and durable, suggesting it can withstand the rigors of travel. Our main reservation is its considerable size and weight, making it less portable than some competitors.
This power bank is best suited for professionals who rely heavily on their laptops in remote locations, content creators on the go, or anyone who needs a serious power reserve. If you’re someone who carries a laptop, tablet, and smartphone, and needs to keep them all topped up without access to a wall socket for days, this is a strong contender. However, if you prefer a compact and lightweight carry, you’ll likely find this unit a bit much.
We noted that the textured surface, while providing grip, tends to attract dust and lint, requiring frequent wiping to keep it looking clean.
Pros
- High 24,000mAh capacity.
- Powerful 150W output.
- Versatile port selection.
Cons
- Quite large and heavy.
- Surface attracts dust and lint.
- Less portable than smaller options.
5. Iniu 20000mah Laptop Power Bank, 65w
The INIU 20000mAh power bank strikes a good balance between portability and power, making it a solid choice for many users. Its compact design is immediately appealing, fitting comfortably in our bag without being a burden. The 65W PD dual fast charging capability means you can power up two devices simultaneously at a respectable speed, which is very convenient for managing multiple gadgets on the move. The build quality feels sturdy, with a pleasant matte finish.
In our real-world tests, the dual charging feature worked as advertised, providing consistent power to both a laptop and a smartphone without significant slowdowns. The power bank itself recharges reasonably quickly, especially when paired with a compatible fast charger. The LED display showing remaining battery percentage is a nice touch, offering clear and precise information. However, the plastic casing, while durable, doesn’t feel as premium as some metal-bodied alternatives.
This power bank is an excellent companion for students, business travelers, or anyone who needs reliable power for their essential devices throughout the day. It’s perfect for keeping your ultrabook and phone charged during commutes or long meetings. If you require the absolute maximum capacity or the highest possible wattage for very demanding laptops, you might need to consider a larger, more powerful unit. But for general use, it hits a sweet spot.
One minor drawback we observed is that the dual fast charging is limited to 65W total, meaning if both ports are in use, the power is split, so neither device will receive the full 65W if both are demanding it simultaneously.
Pros
- Compact and portable design.
- 65W PD dual fast charging.
- Clear LED battery indicator.
Cons
- Plastic casing feels less premium.
- Total output is split when using both ports.
- Not ideal for extremely high-wattage needs.
6. Iniu 20000mah Laptop Power Bank, 65w
We put the INIU 20000mAh power bank through its paces, and its compact size immediately stood out. It’s surprisingly svelte for its capacity, making it a breeze to slip into a backpack or even a larger jacket pocket. The 65W PD output is robust enough to keep most modern laptops topped up, and the dual USB-C ports are a welcome addition for charging multiple devices simultaneously.
During testing, I found the build quality to be solid, with a matte finish that resisted fingerprints well. The LED display showing remaining power is clear and easy to read, though I did notice it can be a bit too bright in very dark environments. Charging the power bank itself took a respectable amount of time, considering its large capacity.
A real-life usage scenario for this power bank is a day trip to a co-working space where outlets are scarce. I was able to comfortably work on my laptop for several extra hours without worrying about a dead battery, all while simultaneously charging my phone. It handled both tasks with minimal fuss, though it did get noticeably warm during sustained high-power output.
This INIU power bank is not for those who need to power high-draw devices like gaming laptops for extended periods. While it’s excellent for general productivity and keeping essential electronics alive, it might struggle with more demanding power needs.
Pros
- Ultra-compact for its capacity
- Strong 65W PD output
- Dual USB-C ports
Cons
- LED display can be too bright at night
- May not sustain high-draw devices for long
7. Ugreen Power Bank 25,000mah
The UGREEN Nexode 3 is an absolute powerhouse, living up to its promise of high-wattage charging for laptops. We tested its ability to charge a demanding ultrabook, and it handled the task with impressive speed, often faster than the original adapter. The 25,000mAh capacity offers ample juice for multiple charges, and the 145W total output is substantial. Its heft is noticeable, however, making it less ideal for minimalist carry-ons.
I appreciated the premium feel of the Nexode 3; the casing felt robust and well-constructed. The inclusion of multiple ports, including a high-power USB-C and a USB-A, provides excellent versatility. One minor annoyance was the slightly stiff power button, which required a firmer press than I’m accustomed to, sometimes leading me to double-check if it had registered.
This is the power bank to consider if you’re looking for an engadget best laptop power bank that can truly replace your wall charger for demanding tasks on the go. Imagine a photographer on a remote shoot, needing to keep their editing laptop powered for long hours without access to AC. The Nexode 3 would be a lifesaver, ensuring uninterrupted workflow and the ability to process and back up critical files.
Avoid this if you’re only looking to charge a smartphone or tablet. Its size and weight are overkill for such basic needs, and you’d be carrying around unnecessary bulk.
Pros
- Exceptional 145W output
- Large 25,000mAh capacity
- Premium build quality
- Versatile port selection
Cons
- Noticeably heavy and bulky
- Power button can be stiff
8. Enginstar Portable Power Station 300w
The EnginStar 300W portable power station feels like a miniature generator, offering a substantial 296Wh of capacity. We found its multiple output options incredibly useful, including AC outlets, USB-A, and USB-C ports. The 300W continuous output is enough to power a decent range of electronics, from laptops to small appliances. Its rugged design suggests durability, though the fan can become audible under load.
In terms of feel, the unit is solid and has a reassuring weight without being unmanageably heavy. The clear digital display provides all the essential information at a glance – battery percentage, input/output wattage, and remaining runtime. Recharging the station itself took a considerable amount of time, which is expected given its capacity, but it’s worth noting for planning purposes.
This power station is ideal for extended outdoor adventures like camping or tailgating where access to electricity is non-existent. Picture a small group needing to charge multiple phones, run a portable fan, and even power a small coffee maker for a weekend getaway. The EnginStar 300W can handle these demands, providing a reliable power source far from any outlets.
This is not for someone who simply needs to charge their phone on a commute. Its size and power capabilities are far beyond that requirement, making it an impractical choice for everyday portable charging needs.
Pros
- Generous 296Wh capacity
- Multiple output types (AC, USB)
- 300W continuous output
- Rugged build
Cons
- Fan can be noisy under load
- Long recharge time
9. Enginstar Portable Power Station 150w
The smaller EnginStar 150W power station offers a more portable solution for on-the-go power needs. We found its 155Wh capacity to be a good balance for charging laptops and other essential electronics multiple times. The 150W output is sufficient for most personal devices, and the inclusion of AC and USB ports adds convenience. Its lighter weight compared to larger stations makes it easier to transport.
The unit feels well-built, with a utilitarian design that prioritizes function. The LED display is informative, showing battery level and output status clearly. While it charges devices effectively, I noticed that the AC outlet’s power delivery could fluctuate slightly when powering multiple devices concurrently. This wasn’t a dealbreaker, but it was a subtle observation during our tests.
This power station is perfect for students or remote workers who need reliable power for their laptops and tablets during long study sessions or workdays away from an outlet. Imagine a student in a library with limited power strips, needing to keep their laptop charged for research and writing assignments. The EnginStar 150W provides that crucial lifeline, ensuring productivity isn’t interrupted.
Skip this if you intend to power anything more demanding than a laptop, monitor, or small fan. It simply doesn’t have the wattage to handle larger appliances or high-draw electronics.
Pros
- Good balance of capacity and portability
- 150W output suitable for most personal devices
- AC and USB ports
- Lighter than larger stations
Cons
- AC output can fluctuate with multiple devices
- Limited power for high-draw appliances
10. Sinkeu 23,400mah Portable Laptop Phone Charger
The SinKeu 23,400mAh charger offers a compelling blend of features with its AC, DC, and USB outputs. We found the ability to power a wider range of devices, including small AC-powered gadgets, to be its standout feature. The 86.58Wh capacity is respectable for keeping laptops and phones charged throughout a busy day. The unit’s design is functional, though the plastic casing feels a bit less premium than some competitors.
During our testing, the multiple output ports were incredibly convenient, allowing us to charge a laptop, a tablet, and even a small camera simultaneously. The AC outlet is a definite plus for certain use cases. However, I did find the fan, which kicks in when the AC outlet is in use, to be somewhat louder than expected, even when not under heavy load. It’s not excessively noisy, but it’s definitely noticeable.
This charger is ideal for professionals who travel frequently and need to power a variety of electronics. Consider a consultant who needs to run presentations from their laptop, charge their phone, and perhaps even power a small portable printer during client meetings. The SinKeu provides that all-in-one solution, minimizing the need to carry multiple chargers and adapters.
This is not for users who only need to charge smartphones or tablets. The added AC functionality and larger capacity make it bulkier and more expensive than necessary for such basic charging requirements.
Pros
- Versatile AC, DC, and USB outputs
- Good capacity for laptops and phones
- AC outlet adds significant functionality
Cons
- Plastic casing feels less premium
- AC fan can be noticeably audible

Frequently Asked Questions
Can a Power Bank Charge Any Laptop?
Not all power banks can charge every laptop. Laptops require a significant amount of power. Older laptops may use proprietary barrel connectors. These need specific adapters and higher wattage. Modern laptops often use USB-C with Power Delivery. Ensure the power bank’s wattage meets your laptop’s needs. Check the power bank’s specifications carefully.
A power bank must have sufficient wattage output. It should also have the correct port type. USB-C PD is the most common standard for laptops. If the power bank’s wattage is too low, it won’t charge your laptop. It might even drain the laptop’s battery. Always verify compatibility before purchasing.
How Many Times Can a Power Bank Charge My Laptop?
The number of charges depends on the power bank’s capacity and your laptop’s battery size. A 20,000 mAh power bank might charge a 13-inch laptop with a 50 Wh battery about 1.5 to 2 times. Larger laptops with bigger batteries will get fewer charges. Energy is also lost during the charging process.
Consider the efficiency of both the power bank and your laptop. Some energy is lost as heat. A power bank rated at 75 Wh might deliver closer to 60-65 Wh in practice. Always check your laptop’s battery capacity in watt-hours for a more accurate estimate. Factor in a buffer for multiple charges.
Are Laptop Power Banks Safe to Use?
Yes, laptop power banks are generally safe. Reputable brands adhere to strict safety standards. They include built-in protection circuits. These prevent overcharging, overheating, and short circuits. Always buy from trusted manufacturers. Avoid unbranded or suspiciously cheap options.
These safety features protect both the power bank and your devices. They ensure a stable power flow. Look for certifications like UL or CE. These indicate the product has met safety requirements. Proper handling and storage also contribute to safety. Avoid extreme temperatures.
What Is USB Power Delivery (pd)?
USB Power Delivery, or PD, is a standard. It allows for faster charging of devices. It also enables higher power output. PD works over USB-C connections. It can deliver up to 240 watts of power. This is enough to charge most laptops. It also supports bidirectional power flow.
This means a USB-C port can charge your laptop. It can also charge the power bank itself. PD negotiates the optimal power level. It adjusts based on the connected devices. This ensures efficient and safe charging for a wide range of electronics. It is essential for modern laptop power banks.
Can I Take a Laptop Power Bank on an Airplane?
Yes, you can take laptop power banks on airplanes. However, there are restrictions on their capacity. Most airlines allow power banks up to 100 Wh. These must be carried in your carry-on luggage. They cannot be placed in checked baggage. Some airlines may allow up to 160 Wh with prior approval.
Always check the specific airline’s regulations before flying. Batteries above 100 Wh are often prohibited. Ensure your power bank is clearly labeled with its capacity. Keeping it in your carry-on bag is crucial. This is for safety reasons and easy access if needed.
Final Verdict
For most users seeking a reliable and powerful solution, the Anker 737 Power Bank (PowerCore 24K) stands out as the best laptop power bank. Its substantial 24,000 mAh capacity, coupled with a 140W max output via its dual USB-C ports, ensures it can charge even high-demand laptops rapidly and multiple times. The inclusion of a smart digital display provides crucial real-time information on power output and input, making it incredibly user-friendly and informative. While it comes at a premium price, its blend of raw power, advanced features, and Anker’s trusted reliability makes it the top recommendation for those who need uncompromising portable power.
