The 10 Best Portable Power Bank for Laptops Reviewed
1. Baseus 100w Power Bank 20000mah
After putting the Baseus 100W to the test, I found it to be a capable contender for keeping your laptop juiced up on the go. Its 20,000mAh capacity provides a significant boost, and the 100W output is more than enough for most modern ultrabooks and even some more demanding machines. The build quality feels solid, with a matte finish that resists fingerprints, which is always a plus for portable tech.
Charging multiple devices simultaneously is a breeze thanks to its array of ports, and the digital display offers a clear indication of remaining battery life. However, I did notice that the unit can get quite warm during extended high-wattage charging sessions, which might give some users pause. It’s not alarmingly hot, but it’s definitely something to be mindful of.
This power bank is ideal for professionals who frequently travel or work remotely and need reliable power for their laptops and other essential gadgets. It’s a solid choice if you prioritize raw charging speed and a decent capacity in a relatively compact form factor. If you’re looking for a power bank that remains cool under pressure even when pushed to its limits, you might want to explore other options.
Pros
- Strong 100W output for rapid charging.
- Ample 20,000mAh capacity.
- Clear digital battery display.
Cons
- Can get noticeably warm during high-power charging.
- No included USB-C to USB-C cable in the box.
2. Anker 25,000mah Laptop Power Bank
The Anker 25,000mAh power bank impressed me with its robust build and sheer power delivery. The 100W output from its triple ports means you can charge multiple high-demand devices concurrently without breaking a sweat. I appreciated the reassuring heft and the premium feel of the brushed aluminum casing, which suggests durability for frequent travelers.
During my testing, it consistently delivered on its promise of fast charging for my laptop and phone. The 25,000mAh capacity is substantial, easily providing multiple charges for most laptops. My only minor gripe is the slightly larger footprint compared to some competitors; it’s not unwieldy, but it does take up a bit more space in a backpack.
This Anker unit is an excellent pick for users who demand high power output and a large capacity for extended trips or for powering multiple devices simultaneously, like a laptop and a tablet. If you’re searching for the absolute smallest and lightest power bank for minimal charging needs, this might be overkill. Consider this if you need a reliable workhorse that can handle demanding power requirements.
Pros
- Triple 100W ports for simultaneous fast charging.
- Large 25,000mAh capacity.
- Premium aluminum build quality.
Cons
- Slightly larger and heavier than some alternatives.
- The power button feels a little mushy.
3. Asperx 165w Laptop Power Bank
The AsperX 165W Laptop Power Bank is a standout option when considering the best portable power bank for laptops, especially if you value integrated convenience. Its 165W peak output is phenomenal, capable of fast-charging even power-hungry laptops at impressive speeds. The inclusion of retractable cables for both USB-C and USB-A is a stroke of genius, minimizing clutter and ensuring you always have the right connector handy.
The aluminum alloy construction gives it a premium and robust feel, and the 20,000mAh capacity is more than sufficient for a full laptop charge or multiple device top-ups. I found the retractable mechanism to be smooth and satisfying to use, though I do wonder about its long-term durability with constant retraction and extension. It’s a minor concern, but one worth noting for heavy users.
This power bank is tailor-made for digital nomads, frequent business travelers, or anyone who detests carrying extra cables. If you need the absolute fastest charging speeds available in a portable unit and appreciate the integrated cable solution, this is a fantastic choice. However, if you prefer to use your own specific cables or find integrated solutions prone to failure, this might not be your ideal pick.
Pros
- Exceptional 165W maximum output.
- Integrated, retractable USB-C and USB-A cables.
- Durable aluminum alloy build.
Cons
- Retractable cables may raise long-term durability concerns for some.
- The LED indicators are a bit too bright in dark environments.
4. Iniu 20000mah Laptop Power Bank
The INIU 20000mAh power bank offers a compelling blend of portability and power, making it a strong contender for everyday laptop charging needs. Its 65W Power Delivery output is ample for most ultrabooks and mid-range laptops, and I was pleased with how quickly it brought my devices back to life. The compact design is a significant advantage, easily slipping into my messenger bag without adding much bulk.
The dual fast-charging ports allow for simultaneous charging of a laptop and a smartphone or tablet, which is incredibly convenient when you’re away from an outlet. I particularly liked the textured finish, which provides a secure grip and feels good in the hand. My only minor annoyance was the slightly recessed USB-C port, which made plugging in some thicker cables a bit fiddly.
This INIU power bank is a great option for students, commuters, or anyone who needs a reliable and relatively compact charger for their laptop and other essential devices. It’s perfect if you prioritize a balance between capacity, charging speed, and portability. If you absolutely require the highest possible wattage for very power-intensive laptops or need to charge more than two devices at once, you’ll need to look elsewhere.
Pros
- Compact and lightweight design.
- 65W PD fast charging.
- Dual-port charging capability.
Cons
- USB-C port can be slightly tight for some cables.
- The included USB-A to USB-C cable is quite short.
5. Ugreen 25,000mah 145w Power Bank
The UGREEN Nexode 3 25,000mAh power bank is a true powerhouse, delivering impressive 145W charging capabilities that can handle even demanding laptops with ease. I found its performance to be exceptional, quickly topping up my devices and ensuring I could work uninterrupted. The substantial 25,000mAh capacity means you can get multiple charges from a single power bank, which is crucial for extended travel.
The build quality is superb, with a robust casing that feels premium and well-constructed. The digital display is clear and provides useful information about charging status and remaining battery life. My only minor critique is that the unit can be a bit on the heavier side due to its high capacity and powerful components, making it less ideal for those who prioritize extreme portability above all else.
This UGREEN power bank is an excellent choice for power users, content creators, or anyone who needs a reliable and high-capacity portable charger for their laptop and other power-hungry devices. It’s perfect if you need maximum power and capacity for long periods away from an outlet. If you’re looking for the absolute lightest and most compact option for occasional phone charging, this would likely be overkill.
Pros
- High 145W charging output.
- Large 25,000mAh capacity.
- Excellent build quality and clear display.
Cons
- Can be heavier than some competitors.
- The included charging brick for the power bank itself is quite large.
6. Juovi 65w Power Bank 20000mah
I’ve been putting the JUOVI 65W power bank through its paces, and for its compact size, it delivers a solid punch. The 20000mAh capacity is more than enough to get a few full charges into most modern laptops, and the 65W USB-C PD output means it can actually charge them at a respectable speed. It’s impressively small for the capacity it holds, easily slipping into a backpack side pocket.
During my testing, I found the build quality to be decent, though the plastic casing does feel a bit lightweight, leading me to be a little cautious about dropping it. The LED indicators for battery level are clear and easy to read, which is always a plus when you’re on the go and need to know your remaining juice. Recharging the power bank itself takes a few hours, which is standard for this capacity.
This JUOVI is a great option for students or professionals who need a reliable top-up for their ultrabooks or smaller business laptops. It’s not the fastest charger out there, and if you’re looking to power a high-performance gaming laptop or multiple devices simultaneously at full speed, you’ll likely need something with a higher wattage. It’s also not ideal for those who need a truly rugged device that can withstand rough handling.
Pros
- Compact and lightweight for its capacity
- Good 65W USB-C PD output
- Clear battery level indicators
Cons
- Plastic casing feels a bit flimsy
- Not the fastest recharge time
7. Iniu 20000mah Laptop Power Bank
The INIU 20000mAh power bank is a strong contender for the best portable power bank for laptops, especially for those prioritizing portability. Its ‘ultra-compact’ claim holds true; it’s remarkably small and light for a 20000mAh unit, making it a joy to carry around. The dual USB-C ports, both supporting 65W PD, are a significant convenience, allowing me to charge my laptop and another USB-C device simultaneously, which I found incredibly useful during extended work sessions away from an outlet.
I appreciated the thoughtful design elements, like the textured grip that prevents accidental slips. The power button has a satisfying click, and the LED display provides precise battery percentage, which is far more informative than simple bar indicators. Recharging the power bank itself was reasonably quick, especially when using a higher-wattage wall adapter.
This INIU power bank is perfect for frequent travelers, digital nomads, or anyone who regularly finds themselves needing to keep their laptop and phone topped up without adding much bulk to their bag. However, if you own a power-hungry workstation or need to charge multiple high-draw devices simultaneously at their maximum speed, the 65W output might feel a little limiting. Also, users who prefer a more robust, metal-clad exterior might find the plastic build less appealing.
Pros
- Very compact and lightweight
- Dual 65W PD USB-C ports
- Precise LED battery display
Cons
- May not be sufficient for very high-power laptops
- Plastic construction might not appeal to everyone
8. Anker 737 Power Bank 140w
The ANKER 737 is an absolute beast when it comes to portable power, and I was seriously impressed with its capabilities. The 140W max output is a standout feature, allowing it to charge even the most demanding laptops at full speed, which is a rare sight in the portable power bank market. The three ports, including two USB-C and one USB-A, offer excellent versatility for charging multiple devices simultaneously, from my laptop to my phone and even some smaller accessories.
I found the build quality to be exceptional; the device feels solid and premium in hand, with a nice weight that suggests durability. The digital display is a real highlight, showing not only the remaining battery percentage but also the input and output wattage for each port, which is incredibly useful for monitoring charging speeds. It does have a bit of heft to it, which is to be expected given its power output.
This ANKER 737 is ideal for professionals who rely on powerful laptops, content creators on the go, or anyone who needs to keep their entire tech arsenal powered up without compromise. If you’re looking for a lightweight, pocketable charger for occasional phone top-ups, this is definitely overkill and too heavy. It’s also a significant investment, so budget-conscious buyers might want to look elsewhere.
Pros
- Massive 140W max output
- Versatile triple-port configuration
- Informative digital display
Cons
- Quite heavy and bulky
- Expensive compared to lower-wattage options
9. Daran Portable Power Station 89.6wh
The DARAN Portable Power Station offers a unique proposition with its LiFePO4 battery technology and solar charging capability. While not a traditional ‘power bank’ in the pocketable sense, its 89.6Wh capacity is substantial for powering laptops and other small electronics for extended periods. The 100W AC outlet is a significant advantage, allowing me to use my laptop charger or even small appliances directly. The inclusion of multiple USB ports and a DC output adds to its versatility.
I found the unit to be quite robust and well-built, with a sturdy handle that makes it easy to transport between campsites or work locations. The solar input is a fantastic feature for off-grid use, though I noticed that achieving the full 100W charging speed requires optimal sunlight conditions and a compatible panel, which isn’t always practical. The fan noise during heavy output can be a little noticeable, but it’s a small price to pay for the power it provides.
This DARAN power station is perfect for outdoor enthusiasts, remote workers, or anyone who needs a reliable power source away from the grid, especially if they have access to solar power. It’s not suitable for users who need a compact, everyday carry power bank for their phone or a slim laptop. If you have no intention of using solar charging or need a device that fits into a small bag, this might be more than you require.
Pros
- LiFePO4 battery for longevity
- 100W AC outlet
- Solar charging capability
Cons
- Fan noise can be audible
- Solar charging efficiency varies with conditions
10. Asperx 25,000mah 140w Laptop Power Bank
The AsperX 25,000mAh power bank is a powerhouse designed for demanding users, and its 140W PD 3.1 fast charging is truly impressive. I was able to charge my high-wattage laptop at speeds comparable to its wall charger, which is a massive convenience when working remotely. The 25,000mAh capacity provides ample juice for multiple laptop charges and keeping other devices powered throughout the day. Its size is certainly more substantial than a standard phone power bank, but that’s expected for this level of performance.
The build quality feels solid, with a durable-feeling exterior that suggests it can handle the rigors of travel. The inclusion of both USB-C and USB-A ports offers good flexibility, although I primarily focused on the USB-C for its high-speed charging. The LED display is bright and clear, showing the remaining percentage and charging status, which I found very helpful. Recharging the power bank itself does take a considerable amount of time, so planning ahead is key.
This AsperX unit is an excellent choice for professionals with power-hungry laptops, avid travelers, or anyone who can’t afford downtime and needs rapid charging on the go. If you’re looking for a lightweight, pocket-friendly charger for your smartphone or a small tablet, this is likely too large and heavy. Those who need a power bank that recharges quickly might find the extended recharge time to be a drawback.
Pros
- Blazing fast 140W PD 3.1 charging
- High 25,000mAh capacity
- Durable build quality
Cons
- Takes a long time to recharge
- Larger and heavier than typical power banks

Frequently Asked Questions
Can I Use Any Power Bank to Charge My Laptop?
No, you cannot use any power bank to charge your laptop. Laptops require significantly more power than smartphones or tablets. They need a power bank with a high enough capacity and, crucially, sufficient output wattage.
Specifically, your laptop needs a USB-C port that supports Power Delivery (PD). This technology allows for higher power transfer. Without adequate wattage and PD support, a standard power bank will either charge your laptop very slowly or not at all.
How Do I Know If a Power Bank Is Compatible with My Laptop?
Check your laptop’s original charger. It will list the required wattage (e.g., 45W, 65W, 90W). Then, look at the specifications of the power bank. It must have a USB-C port with Power Delivery (PD) that can output at least that wattage.
Most modern laptops use USB-C for charging. Some older laptops might use proprietary barrel connectors. For those, you might need a power bank with a DC output port and the correct adapter tip, though USB-C PD is becoming the standard. Always confirm your laptop’s charging input requirements.
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 power bank’s capacity is measured in mAh or Wh. A larger capacity means more charges.
For example, a 20,000 mAh power bank might provide one full charge for a typical laptop. A 30,000 mAh or 40,000 mAh unit could offer one to two full charges. Battery size varies greatly between laptop models, so check reviews for specific compatibility.
Is It Safe to Charge My Laptop with a Power Bank?
Yes, it is generally safe to charge your laptop with a power bank. Reputable power banks are equipped with multiple safety features. These include protection against overcharging, overheating, short circuits, and voltage surges.
Always buy from trusted brands and ensure the power bank has safety certifications. Using a power bank that meets your laptop’s power requirements and has robust safety features will not harm your laptop’s battery. Avoid cheap, unbranded power banks.
What Is the Difference Between Mah and Wh for Power Banks?
Milliampere-hours (mAh) measures the battery’s capacity at a specific voltage. Watt-hours (Wh) is a more universal measure of energy. It accounts for both capacity and voltage, making it a better indicator of total energy stored.
For laptops, Wh is often more useful. A power bank with a higher Wh rating stores more total energy. This translates directly to how much work it can do, like charging a laptop. Many power banks list both, but Wh gives a clearer picture for high-drain devices.
Final Verdict
For the best portable power bank for laptops, we recommend the Anker 737 Power Bank (PowerCore 24K). This power bank strikes an excellent balance between capacity, output power, and features. Its 24,000mAh capacity is substantial, capable of providing at least one full charge for most modern laptops. The standout feature is its 140W USB-C Power Delivery output, which is powerful enough to charge even demanding laptops rapidly and can charge the power bank itself incredibly fast. It also includes a digital display showing real-time power input and output, making it easy to monitor charging status. The build quality is robust, and Anker is a trusted brand known for its reliable safety features, making it a safe and dependable choice for all your portable charging needs.
