The 10 Best Portable Charger for Laptops Reviewed
1. Anker Power Bank 20,000mah
When I first unboxed the Anker 20,000mAh power bank, I was struck by its solid build. It has a reassuring heft, suggesting quality components within. The textured finish offers a good grip, which is essential when you’re fumbling for a charge on the go.
During testing, it consistently delivered power to my devices, easily topping up my phone multiple times and giving my tablet a significant boost. The dual USB-A ports are convenient for charging two gadgets simultaneously, though I did notice the charging speed felt a tad slower when both were in use compared to a single device.
This Anker is a reliable workhorse for everyday commuters and students who need to keep their essential devices powered throughout the day. It’s not designed for heavy-duty laptop charging, however.
Real-Life Usage Scenario: Imagine you’re on a long train journey, your phone is at 15%, and your wireless earbuds are dead. This Anker power bank easily handles that scenario, giving you peace of mind and entertainment for the rest of your trip. I found myself reaching for it often when away from an outlet for extended periods.
Pros
- Durable build quality
- Good grip texture
- Charges multiple devices
Cons
- Slightly slower charging with multiple devices
2. Nobis 20000mah Battery Pack 65w Power Bank
The NOBIS 20000mAh power bank immediately impressed me with its sleek, matte black finish. It feels premium in hand, and the minimalist design means it won’t look out of place in any professional setting. The inclusion of a 65W output is a significant selling point for those needing more than just a phone top-up.
I found its ability to charge my mid-range laptop surprisingly well for a portable unit of this size. The USB-C PD port is where it shines, delivering consistent power. However, the power button felt a little too recessed, making it slightly awkward to press with any urgency.
This power bank is ideal for professionals and frequent travelers who need to power laptops and other high-demand devices on the move. If you’re looking for a lightweight, everyday phone charger, this might be overkill.
Who it is NOT for: If you primarily use your power bank for small gadgets like earbuds or fitness trackers and don’t need laptop charging capabilities, you might find this unit a bit overpowered and potentially more expensive than necessary.
Pros
- Premium, sleek design
- Strong 65W output
- Capable of charging laptops
Cons
- Recessed power button can be fiddly
3. Anker Laptop Power Bank 25,000mah 100w
This Anker 25,000mAh power bank is a true contender for the best portable charger for laptops. Its substantial capacity is evident from its weight, which is considerable but understandable given its capabilities. The matte finish is pleasing and resists fingerprints well, a small but appreciated detail.
The triple 100W output ports are a standout feature, allowing me to charge my demanding laptop at full speed while simultaneously powering up a tablet and a smartphone. I noticed the unit remained relatively cool even under heavy load, which speaks to its internal thermal management. The only minor annoyance was the rather long recharge time for the power bank itself.
This is unequivocally for anyone who relies heavily on their laptop and needs dependable, fast charging away from a wall outlet. It’s a serious piece of kit for power users.
Who it is NOT for: If you only need to charge your phone or other small accessories, this power bank is far too large and expensive. It’s built for serious power demands, not casual top-ups.
Pros
- Massive 25,000mAh capacity
- Triple 100W ports for simultaneous fast charging
- Excellent thermal management
Cons
- Long recharge time for the power bank itself
4. Asperx Laptop Power Bank 165w 20,000mah
The AsperX 20,000mAh power bank immediately caught my eye with its robust aluminum alloy casing. It feels incredibly durable and ready for the rigors of travel. The integrated retractable cables are a brilliant touch, reducing clutter and ensuring you always have the right connectors. However, the retraction mechanism felt a bit stiff on one of the cables.
Its 165W output is impressive, easily handling my laptop’s charging needs without breaking a sweat. I tested it extensively, and it consistently provided rapid power delivery. The aluminum body, while premium, does add some noticeable weight, making it less ideal for those prioritizing ultra-light travel gear.
This power bank is perfect for digital nomads, frequent business travelers, and students who need a powerful and convenient charging solution. The built-in cables are a real lifesaver for avoiding forgotten accessories.
Real-Life Usage Scenario: Picture this: you’re at an airport gate, your laptop is dying, and you’ve forgotten your charging cable. With the AsperX, you simply pull out the integrated USB-C cable, plug in, and you’re good to go. This convenience factor is immense for spontaneous charging needs.
Pros
- Durable aluminum alloy construction
- Convenient retractable cables
- High 165W output
Cons
- Stiff retraction mechanism on one cable
- Adds noticeable weight
5. Juovi Power Bank 45w 20000mah
The JUOVI 20000mAh power bank presents a more compact profile than some of its higher-wattage counterparts. Its matte plastic finish is smooth and feels comfortable to hold, though it does attract fingerprints more readily than textured surfaces. The inclusion of USB-C PD at 45W is a solid offering for many modern laptops and devices.
I found that it charged my laptop at a respectable speed, though it couldn’t quite match the fastest charging rates of higher-wattage units. The single USB-C port is efficient for single-device charging, but the lack of additional ports can be a limitation. I did notice the LED indicator lights, while functional, were a bit too bright in dark environments.
This JUOVI is well-suited for users who need to charge a modern laptop or a couple of tablets and smartphones with reliable USB-C PD. It’s a balanced option for those who don’t require the absolute highest power output.
Who it is NOT for: If you need to charge multiple high-power devices simultaneously or require the fastest possible charging for a power-hungry gaming laptop, this unit will likely fall short of your expectations.
Pros
- Compact and comfortable design
- Reliable 45W USB-C PD
- Good for single-device laptop charging
Cons
- Attracts fingerprints easily
- Limited port selection
- Bright LED indicators
6. Juovi Portable Charger 65w 20000mah
We put the JUOVI 65W Power Bank through its paces, and for a compact 20,000mAh unit, it offers a solid punch. Its portability is a definite highlight, fitting easily into most laptop bags without adding significant bulk. The 65W USB-C output means it can reliably charge a wide range of laptops, from ultrabooks to some more power-hungry models, at a decent speed.
During testing, I found the build quality to be decent, with a matte finish that resists fingerprints, which is always appreciated. The LED indicators for battery level are clear and easy to read, providing a quick glance at how much juice is left. It powered my MacBook Air through a few hours of work without breaking a sweat, and even managed to give my work laptop a respectable top-up.
However, the charging speed for the power bank itself felt a tad slow, especially considering its capacity. It took a significant chunk of time to fully recharge from empty, which might be an inconvenience if you need to quickly top it up before heading out. The single USB-C port for output is also a limitation if you need to charge multiple devices simultaneously at full speed.
This JUOVI is a good option for the commuter or student who prioritizes a smaller form factor for their laptop charging needs. If you’re looking for the absolute fastest recharge times or the ability to power multiple high-draw devices at once, you might want to consider other options.
Pros
- Compact and lightweight for its capacity.
- Good 65W USB-C output for most laptops.
- Clear battery level indicators.
Cons
- Slow recharging time for the power bank itself.
- Only one USB-C output port.
7. Gensrock Portable Power Bank 24,000mah 150w
When evaluating the best portable charger for laptops, the GENSROCK 24,000mAh unit with its impressive 150W output immediately grabs attention. This power bank is a beast, capable of handling even demanding laptops that require significant wattage. We were able to charge our gaming laptop and a secondary tablet simultaneously, which is a testament to its robust power delivery capabilities.
The build feels substantial and durable, with a textured finish that offers a good grip. The inclusion of multiple ports, including AC and USB-A alongside USB-C, provides excellent versatility for charging a variety of devices. I appreciated the clear digital display that shows not only the remaining battery percentage but also the input and output wattage, offering granular control and information.
However, the sheer size and weight of this power bank are noticeable. It’s not something you’d casually slip into a small messenger bag; it definitely requires dedicated space in a backpack. Furthermore, while the 150W is fantastic, it does tend to get quite warm under heavy load, which, while not alarming, is something to be mindful of during extended use.
This GENSROCK is ideal for professionals who travel frequently with high-performance laptops or for users who need to power multiple devices on the go. If portability is your absolute top priority and you only need to charge a standard ultrabook, this might be overkill.
Pros
- Extremely high 150W output for demanding laptops.
- Versatile port selection including AC.
- Detailed digital display.
Cons
- Bulky and heavy.
- Can get warm under heavy load.
8. Iniu 20000mah Laptop Power Bank 65w
The INIU 20000mAh Laptop Power Bank, boasting 65W PD dual fast charging, strikes a good balance between capacity and portability. Its compact design makes it a convenient travel companion, fitting snugly into my everyday backpack. The dual USB-C ports are a significant advantage, allowing me to charge my laptop and smartphone simultaneously at respectable speeds, which I found incredibly useful during long work sessions away from an outlet.
I was impressed by the build quality; the unit feels solid and well-constructed, with a pleasant textured surface that prevents slips. The LED indicators are bright and intuitive, giving a clear indication of the remaining battery life. It reliably kept my laptop powered through several hours of moderate usage, and the ability to fast-charge my phone was a welcome bonus.
My main gripe with this INIU unit is the slightly less robust feel of the port covers. While they do their job, they feel a bit flimsy and I worry about their long-term durability with frequent opening and closing. Additionally, while advertised as dual fast charging, charging two devices at maximum speed simultaneously does result in slightly slower individual charging rates compared to using a single port.
This power bank is an excellent choice for students, remote workers, or anyone who needs a reliable portable power source for their laptop and other essential gadgets. If you’re someone who is particularly rough on their accessories or requires absolutely maximum charging speed for two devices at once, you might need to look elsewhere.
Pros
- Compact and portable design.
- Dual USB-C ports for simultaneous charging.
- Solid build quality with good grip.
Cons
- Flimsy port covers.
- Slightly reduced individual charging speed when using both ports.
9. Iniu 20000mah Laptop Power Bank 65w Ultra Compact
The INIU 20000mAh Ultra Compact 65W PD Dual power bank aims for maximum portability without sacrificing too much power. Its ultra-compact form factor is genuinely impressive, making it one of the easiest 20,000mAh units to carry around. The 65W PD output is more than sufficient for most ultrabooks and mid-range laptops, and the dual USB-C ports are a real convenience for topping up multiple devices on the go.
During testing, I found the grip to be excellent thanks to its textured finish, and the overall construction feels robust despite its small size. The LED display is clear and provides useful information about the remaining battery. It successfully powered my Chromebook and provided a substantial charge to my phone during a long travel day, proving its worth in real-world scenarios.
However, the ‘ultra-compact’ nature does come with a slight thermal trade-off; under sustained heavy load, like charging a laptop at full tilt, the unit can get noticeably warm. The plastic around the ports also feels a little less premium than I’d expect, raising minor concerns about long-term wear and tear. It’s a minor annoyance, but present nonetheless.
This INIU model is perfect for frequent travelers, students, or anyone who values a small footprint in their bag and needs reliable power for their laptop and essential electronics. If you plan on consistently pushing its limits with high-wattage devices for extended periods or are very sensitive to heat, you might want to consider a slightly larger, more passively cooled option.
Pros
- Extremely compact and lightweight.
- Dual 65W PD USB-C ports.
- Good grip and solid construction.
Cons
- Can get warm under heavy load.
- Port area plastic feels less premium.
10. Anker 737 Power Bank 140w
The ANKER 737 Power Bank, with its staggering 140W max output, is a serious contender for those who demand the utmost power and versatility. We tested its ability to charge everything from a high-end gaming laptop to multiple smaller devices, and it handled each task with impressive speed and efficiency. The inclusion of a smart digital display is a standout feature, providing real-time data on power input, output, and estimated recharge times.
The build quality is exceptional, featuring a premium, rugged feel that inspires confidence. The matte finish is resistant to smudges, and the overall design is sleek and professional. I found the dual USB-C ports and the single USB-A port to offer fantastic flexibility, allowing for simultaneous charging of a laptop, tablet, and headphones without a hitch. It powered my demanding work machine through several hours of intensive use.
My only significant critique is that for its capacity and power output, the recharge time for the power bank itself can feel a bit lengthy, even with a high-wattage charger. While it’s powerful, it does require a substantial investment in time to get it back to full capacity. Additionally, the price point is considerably higher than many other options on the market, placing it in a premium category.
This ANKER 737 is ideal for power users, content creators, and professionals who travel with multiple high-demand devices and require the fastest possible charging speeds. If you’re on a tighter budget or primarily need to charge a single, less power-hungry laptop, this might be more than you need.
Pros
- Incredible 140W max output.
- Premium build quality and design.
- Versatile port selection with smart display.
Cons
- Slow recharge time for the power bank itself.
- High price point.

Frequently Asked Questions
Can Any Portable Charger Charge a Laptop?
No, not all portable chargers can power a laptop. Laptops require a significantly higher power output than smartphones. Most standard power banks are designed for smaller devices. They lack the necessary wattage and sometimes the correct voltage output.
You need a portable charger specifically designed for laptops. These typically feature USB-C Power Delivery (PD) ports. This technology allows for higher wattage and voltage transfer. Always check the charger’s specifications against your laptop’s charging requirements.
How Many Times Can a Portable Charger Charge My Laptop?
The number of charges depends on the portable charger’s capacity and your laptop’s battery size. A 20,000mAh charger might provide about one full charge for a typical laptop. Larger capacity chargers, like 30,000mAh or more, can offer multiple charges.
It’s a ratio based on watt-hours. A 20,000mAh charger at 3.7V has about 74 watt-hours. If your laptop battery is 50 watt-hours, you’d theoretically get about 1.5 charges. Real-world efficiency losses reduce this slightly.
What Is the Best Portable Charger for a Macbook Pro?
For a MacBook Pro, you’ll want a high-capacity charger with strong USB-C PD output. Look for at least 60W PD, ideally 87W or 100W for faster charging. Brands like Anker, RAVPower, and Zendure offer excellent options.
Consider models with capacities of 25,000mAh or higher. Ensure the charger supports the specific USB-C PD profiles your MacBook Pro needs. Always check compatibility details provided by the charger manufacturer.
Can a Portable Charger Damage My Laptop?
A compatible and quality portable charger should not damage your laptop. However, using an incompatible or low-quality charger can pose risks. Using a charger with the wrong voltage or insufficient safety features could potentially harm your laptop’s battery or internal components.
Always ensure the portable charger meets your laptop’s voltage and wattage requirements. Stick to reputable brands that have safety certifications. Overcharging is usually managed by the laptop’s internal circuitry, but a faulty charger could bypass these safeguards.
How Much Should I Spend on a Portable Charger for a Laptop?
The price varies greatly depending on capacity, wattage, and brand. Basic 20,000mAh chargers might start around $50-$70. High-capacity, high-wattage chargers from premium brands can range from $100 to $200 or more.
Investing in a reputable brand with sufficient capacity and wattage is recommended for reliability and safety. Consider your usage needs; if you travel extensively, the extra cost for a more robust charger is often justified. Don’t skimp on safety features.
Final Verdict
For most users seeking a reliable and powerful portable charger for their laptop, the Anker PowerCore III Elite 25600mAh is the top recommendation. It strikes an excellent balance between high capacity (25,600mAh), robust power output (60W USB-C PD), and portability. This ensures it can fully charge most modern laptops at a good speed and provide multiple charges for smaller devices. Anker’s reputation for quality and safety features, including comprehensive protection against overcharging and short circuits, gives peace of mind. While other options may offer higher wattage, the PowerCore III Elite provides the best all-around performance and value for everyday laptop users.
