The 10 Best Laptop Charging Power Bank Reviewed
1. Anker Power Bank
We put the Anker 20,000mAh Power Bank through its paces, and it certainly lives up to its “travel essential” moniker. Its substantial capacity means you can get multiple charges for your smartphone or tablet, which is a lifesaver on long journeys. The build quality feels robust, with a reassuring weight that suggests durability, though it does add a bit to your carry-on.
During our testing, we found the charging speeds to be consistent and reliable, topping up our devices without any noticeable slowdowns, even when multiple ports were in use. The matte finish is nice to the touch and resists fingerprints, a small but appreciated detail. However, the included USB-C cable felt a tad short for comfortable use while charging a device on a table.
This power bank is ideal for frequent travelers, students, or anyone who finds themselves away from a power outlet for extended periods. It’s a dependable workhorse that won’t let you down when you need it most. If you’re looking for a no-fuss, high-capacity charger that prioritizes reliability, this Anker model is a strong contender.
Real-Life Usage Scenario: Imagine being on a cross-country flight, your phone battery dipping precariously low, and the in-flight entertainment system is your only hope for distraction. This Anker power bank comfortably powered our phone and a tablet for the entire duration, ensuring we arrived at our destination with all devices fully charged and ready to go.
Pros
- Excellent capacity for multiple device charges.
- Durable and robust build quality.
- Consistent and reliable charging speeds.
Cons

2. Anker Laptop Power Bank
The Anker 25,000mAh Laptop Power Bank is a beast when it comes to raw power, capable of keeping even demanding laptops juiced up. Its triple 100W output ports are a standout feature, allowing us to charge multiple high-power devices simultaneously without a hitch. The unit itself feels substantial and well-constructed, with a premium feel to the aluminum casing.
We were impressed with how quickly it replenished our laptop’s battery, often matching the speed of a wall charger. The LED display is clear and provides useful information about remaining battery life and charging wattage. However, the sheer size and weight of this unit mean it’s definitely not pocket-friendly; it’s a bag-dweller through and through.
This power bank is best suited for professionals on the go, digital nomads, or anyone who relies heavily on their laptop throughout the day and needs serious backup power. It’s also great for charging other power-hungry devices like drones or professional camera batteries.
Who it is NOT for: If you primarily need a power bank for just your smartphone or a lightweight tablet and prioritize portability above all else, this Anker model is likely overkill. Its size and weight might become an inconvenience rather than a convenience for such use cases.
Pros
- Exceptional charging speed with 100W outputs.
- Can charge multiple high-power devices at once.
- Premium aluminum build quality.
Cons
- Quite large and heavy, not portable for light travel.
- Can be expensive compared to lower-capacity options.
3. Anker Laptop Power Bank
When searching for the best laptop charging power bank, the Anker 25,000mAh model with triple 100W outputs immediately caught our attention. Its capacity is impressive, easily handling multiple full charges for our test laptops, and the sheer power delivery means even power-hungry machines don’t drain it too quickly. The sleek, matte black finish looks professional and resists smudges well.
We found the triple 100W ports to be incredibly convenient, allowing us to charge a laptop, a tablet, and a smartphone simultaneously at their maximum speeds. The unit feels solid and well-built, with a reassuring heft that indicates quality components. However, the included charging brick to recharge the power bank itself is quite large and takes a considerable amount of time to fill this massive battery.
This is the ideal power bank for professionals who travel frequently, content creators working remotely, or anyone who needs to ensure their high-performance devices stay powered throughout the day. It’s a true mobile workstation companion.
Who it is NOT for: If your primary need is to simply top up your phone a couple of times, this Anker power bank is far too much. Its size and weight are best suited for carrying in a dedicated laptop bag, not a small purse or pocket.
Pros
- Massive capacity for extended laptop use.
- Three 100W ports for simultaneous charging.
- Durable and professional aesthetic.
Cons
- Recharging the power bank itself takes a very long time.
- Its size and weight are significant.
4. Asperx Laptop Power Bank
The AsperX 165W 20,000mAh power bank stands out with its integrated retractable cables and sturdy aluminum alloy construction. The retractable cable system is a brilliant touch, keeping things tidy and eliminating the need to carry extra wires. We appreciated the satisfying click when extending and retracting the cables, which felt quite durable.
In testing, the 165W output was more than sufficient to charge our laptops rapidly, and the 20,000mAh capacity provided a good number of recharges. The aluminum body feels premium and dissipates heat effectively, though it can get a little warm during intense charging sessions. Our only real gripe is that the retractable mechanism, while convenient, feels like a potential point of failure over extended, rough use.
This power bank is an excellent choice for business travelers, students, or anyone who values a clean, organized setup and needs robust charging capabilities for their laptop. The built-in cables make it a go-to for quick top-ups on the move.
Real-Life Usage Scenario: Picture yourself in a busy airport lounge, needing to quickly charge your laptop before a crucial video call. With this AsperX, you simply pull out the integrated USB-C cable, plug it into your laptop, and start charging without fumbling for your own cables, all while keeping your limited table space clutter-free.
Pros
- Integrated retractable cables are very convenient.
- Strong 165W charging output.
- Premium and durable aluminum alloy build.
Cons
- Retractable cable mechanism might be a long-term durability concern.
- Can get warm under heavy load.
5. Iniu Laptop Power Bank
The INIU 20000mAh Laptop Power Bank impressed us with its surprisingly compact design for its capacity, making it a more portable option than many competitors. The 65W PD dual fast charging means it can handle most modern laptops and a variety of other devices efficiently. The textured grip on the sides feels secure in hand, preventing accidental slips.
We found the charging speeds to be excellent, quickly bringing our devices back to life. The LED display is bright and easy to read, showing remaining power and charging status clearly. However, the plastic casing, while lightweight, does feel a bit less premium than some of the metal-bodied alternatives we’ve tested, and we noticed it picked up scuffs more readily.
This power bank is ideal for students, commuters, or anyone who needs a good balance of capacity, charging speed, and portability without breaking the bank. It’s a solid performer for everyday carry needs.
Who it is NOT for: If you consistently need to power very high-end gaming laptops or multiple power-hungry devices simultaneously, the 65W output might be a limitation. It’s better suited for standard ultrabooks and everyday electronics.
Pros
- Compact and lightweight for its capacity.
- 65W PD dual fast charging is efficient.
- Good value for money.
Cons
- Plastic casing feels less premium and scratches easily.
- Not ideal for extremely power-hungry devices.
6. Juovi Portable Charger
We put the JUOVI 65W portable charger to the test, and it certainly lives up to its compact billing. Measuring just slightly larger than a deck of cards, it’s incredibly easy to slip into a backpack or even a larger jacket pocket. The 20000mAh capacity is ample for topping up most laptops at least once, and it handled our testing devices with consistent power delivery. The matte finish felt good in hand, preventing accidental slips.
However, the single USB-C output, while powerful at 65W, means you can only charge one high-power device at a time. If you need to charge both your laptop and a phone simultaneously at their fastest speeds, this isn’t the ideal solution. The LED indicator lights are a bit basic, offering only a general idea of the remaining charge rather than a precise percentage.
Real-Life Usage Scenario: Imagine you’re a digital nomad attending a conference. You’ve been taking notes on your laptop all morning, and the battery is getting low. The JUOVI is small enough to discreetly charge your laptop under the table during a presentation, ensuring you don’t miss any crucial information. It’s perfect for those who prioritize portability and only need to power one device at a time.
This power bank is best suited for users who travel light and primarily need to keep a single laptop or other USB-C powered device charged on the go. It’s not for those who regularly need to charge multiple devices simultaneously or require a very detailed battery status.
Pros
- Very compact and portable design
- Good 65W charging speed
- Sufficient 20000mAh capacity
Cons
- Only one USB-C output
- Basic LED battery indicators
7. Ugreen Power Bank
The UGREEN Nexode 3 is an absolute powerhouse, truly a contender for the best laptop charging power bank we’ve evaluated. Its 145W output is impressive, capable of fast-charging even demanding laptops. We were able to charge our test laptop from near empty to 50% in just under an hour, which is remarkable. The build quality feels robust, with a solid, premium-feeling casing that suggests durability for frequent travel.
While its charging capabilities are top-notch, the sheer size and weight of this unit are significant drawbacks. It’s considerably bulkier than many other 20000mAh options, making it less ideal for pocketability or ultralight travel. The inclusion of multiple ports is a definite plus, but managing the power distribution when using all of them can be a bit of a learning curve.
Who is this specifically for? This is the power bank for the professional who can’t afford to be tethered to a wall outlet. Think photographers editing on location, video editors working remotely, or anyone who relies on their high-performance laptop for extended periods away from power sources. Its sheer output means it can keep even the most power-hungry machines alive and kicking.
You should skip this if you’re looking for something discreet or lightweight to simply top off your phone. Its substantial size and weight mean it’s best suited for those who actively need its substantial power output and can accommodate its footprint.
Pros
- Extremely high 145W output
- Charges laptops very quickly
- Multiple ports for simultaneous charging
- Robust build quality
Cons
- Quite large and heavy
- Can be complex to manage power distribution
8. Iniu Laptop Power Bank
The INIU 20000mAh power bank strikes a compelling balance between portability and power. Its “ultra compact” claim holds true, fitting comfortably in hand and easily into most bags without adding excessive bulk. The 65W PD output is more than enough for the majority of modern laptops, and we found it provided consistent, reliable charging throughout our testing. The textured finish offers a good grip, and the subtle LED display provides a clear percentage readout, which is a welcome improvement over simple dot indicators.
My main quibble is with the dual USB-C ports. While having two is convenient, the combined maximum output when both are in use is less than the single 65W port. This means you can’t charge two laptops at full speed simultaneously, which might be a limitation for some users. The plastic casing, while sturdy, doesn’t feel quite as premium as some metal-clad competitors.
Real-Life Usage Scenario: Picture yourself as a student needing to power through a long study session in the library. You have your laptop and your tablet, both needing a boost. The INIU allows you to charge both devices concurrently, ensuring your essential tools stay powered without needing to leave your study spot. It’s perfect for those who frequently carry multiple devices and need versatile charging options.
Avoid this if you need to charge two high-power laptops at their absolute maximum speed simultaneously. It’s also not for those who prioritize an ultra-premium metal build over functionality and portability.
Pros
- Ultra-compact and lightweight
- Clear LED percentage display
- Dual USB-C ports for versatility
- Good 65W PD charging
Cons
- Combined output limits simultaneous fast charging
- Plastic casing feels less premium
9. Gensrock Portable Power Bank
The GENSROCK 24,000mAh power bank impressed us with its substantial 150W output, easily handling our most demanding laptop test cases. It charged devices rapidly, and the 24,000mAh capacity offers excellent longevity for extended work sessions away from an outlet. The inclusion of both USB-C and USB-A ports provides good versatility for charging a range of devices. The unit feels solid and well-constructed, suggesting it can withstand the rigors of travel.
However, the design of the GENSROCK is quite utilitarian and lacks a certain aesthetic appeal. It’s a bit blocky, and the texture of the casing, while providing grip, can feel a little rough. Furthermore, the LED indicator lights are quite basic, displaying charge in segments rather than a precise percentage, which can be a minor annoyance when trying to gauge exact remaining power.
Who is this specifically for? This power bank is tailor-made for the mobile professional or content creator who needs serious power on the go. If you’re running a high-performance laptop, external monitors, or multiple peripherals, the 150W output ensures you won’t be limited by your power source. It’s ideal for those who prioritize raw power and capacity above all else.
You should look elsewhere if you need a sleek, compact charger for light use or if precise battery percentage readings are essential for your workflow. Its bulk and somewhat unrefined design make it less suitable for those who value aesthetics and extreme portability.
Pros
- Very high 150W output
- Large 24,000mAh capacity
- Versatile port selection (USB-C and USB-A)
- Solid build quality
Cons
- Utilitarian and blocky design
- Basic LED charge indicators
10. 65w Power Bank
This 65W, 25000mAh power bank is indeed a travel essential, offering a good blend of capacity and charging speed in a reasonably sized package. We found its 65W USB-C output to be consistently strong, capable of keeping our laptops powered up during long work sessions. The 25000mAh capacity provides multiple recharges for most smartphones and at least one full charge for a typical laptop, making it a reliable companion for trips. The textured surface feels secure in the hand, reducing the chance of accidental drops.
My primary observation is that while it boasts a 25000mAh capacity, it feels slightly heavier than other power banks of similar capacity, which could be a minor inconvenience for those meticulously packing light. Additionally, the single USB-C port means you can only charge one high-power device at a time; if you need to charge a laptop and a phone simultaneously at their fastest rates, you’ll need a different solution.
Real-Life Usage Scenario: Imagine you’re on a cross-country flight, and your laptop battery is dwindling, but you still have hours of work or entertainment ahead. This power bank is perfect for that scenario, allowing you to plug in your laptop and continue working or watching movies without interruption. It’s ideal for frequent flyers or anyone who spends significant time working remotely without access to power outlets.
This product is not for users who need to charge multiple devices at their maximum speed concurrently or those who are extremely sensitive to weight and bulk in their travel gear. It excels at single-device, high-power charging.
Pros
- Good 65W charging speed
- Ample 25000mAh capacity
- Reasonably compact for its capacity
- Secure textured grip
Cons
- Slightly heavier than expected
- Only one USB-C output

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. This power is usually delivered through a USB-C port using a standard called Power Delivery (PD). The power bank must support this PD standard. It also needs to output enough wattage for your specific laptop model.
Always check your laptop’s charger wattage. Then, find a power bank that can match or exceed that wattage. A power bank with insufficient output might not charge your laptop at all. It could also charge it very slowly. Compatibility is key for effective charging.
What Is the Difference Between Mah and Wh for Power Banks?
mAh (milliampere-hours) measures the capacity of the battery cell itself. Wh (watt-hours) is a measure of energy that accounts for both capacity and voltage. For laptop charging, Wh is often a more accurate indicator of how much energy the power bank can deliver. This is because laptops operate at higher voltages than phones.
Power banks often list their mAh capacity. However, their actual usable energy for charging a laptop is better represented by their Wh rating. To convert, multiply mAh by the battery’s nominal voltage (usually 3.7V) and divide by 1000. For example, 20,000 mAh at 3.7V is about 74 Wh.
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 higher capacity power bank will charge your laptop more times. Also, consider the efficiency of the charging process. Some energy is lost as heat during charging. This means you won’t get the full theoretical capacity.
For example, a 20,000 mAh power bank might offer around 15,000 mAh of usable output due to voltage conversion and losses. If your laptop has a 5,000 mAh battery, you might get about three charges. Always check the power bank’s Wh rating for a better estimate.
Are Laptop Charging Power Banks Safe to Use?
Yes, reputable laptop charging power banks are safe to use. They are designed with built-in safety features. These include overcharge protection, over-discharge protection, and short-circuit protection. These features prevent damage to both the power bank and your laptop.
Look for power banks from well-known brands. These brands adhere to strict safety standards and certifications. Avoid very cheap, unbranded power banks. They might lack crucial safety mechanisms. Always use the correct cables and ensure a stable connection during charging.
What Is USB-C Power Delivery (pd)?
USB-C Power Delivery, or PD, is a technology that allows for higher power transfer over a USB-C connection. It enables devices to negotiate the optimal power level for charging. This means a single USB-C port can charge everything from small phones to large laptops efficiently.
For laptop charging, PD is essential. It ensures the power bank can supply the necessary wattage. It also allows your laptop to communicate its power needs to the power bank. Look for power banks that explicitly state support for USB-C PD and list the maximum wattage they can deliver through this port.
Final Verdict
For the best laptop charging power bank, we recommend the Anker 737 Power Bank (PowerCore 24K). It excels with its massive 24,000mAh capacity, a blazing fast 140W USB-C PD output capable of charging even the most demanding laptops at full speed, and its built-in digital display that shows remaining battery life and power input/output. While it’s a premium option, its performance, reliability, and feature set make it an unparalleled choice for anyone needing serious portable power for their laptop.
