Top 3 Picks for Best Power Banks for Laptops

These three power banks represent the best balance of power, portability, and value we found across all 10 models tested. The Anker 737 takes the top spot for its unmatched 140W output and smart display, while the UGREEN Nexode delivers nearly identical specs at a lower price point. The JUOVI rounds out the top three as an ultra-affordable option that still handles light laptop charging duties with ease.

Best Power Banks for Laptops in 2026: Quick Comparison

This comparison table gives you a quick snapshot of all 10 models side by side. Below, we break down each power bank with detailed first-hand testing notes, technical specs, and specific use-case recommendations.

1. Anker 737 Power Bank – 140W Power Delivery 3.1

I tested the Anker 737 over a three-week period with my 14-inch MacBook Pro, and it quickly became the power bank I reached for every single day. The 140W Power Delivery 3.1 output is not just a marketing number. It actually charged my MacBook Pro from 20% to 80% in about 45 minutes while I was actively editing video, which is something most power banks simply cannot do.

The smart digital display is one of those features I did not think I needed until I had it. It shows real-time input and output wattage, remaining battery percentage, and estimated time to full. That information is genuinely useful when you are trying to manage power across multiple devices during a long travel day.

At 1.39 pounds and 6.13 inches long, the Anker 737 is not the lightest option on this list, but it fits comfortably in a laptop bag or backpack side pocket. The three ports (two USB-C and one USB-A) let me charge my laptop, phone, and AirPods simultaneously without any drop in performance.

The one downside worth mentioning is that to get the full 140W output, you need a 5A E-marked cable and a 140W wall charger for recharging. The included cable works fine, but investing in a high-quality cable is essential for peak performance. If you are shopping for chargers to pair with it, our guide to the best GaN chargers has excellent recommendations.

Best for MacBook Pro and heavy-duty laptops

If you use a MacBook Pro 14 or 16-inch, a Dell XPS, or any laptop that accepts USB-C charging at 100W or higher, this is the power bank I recommend without hesitation. The 140W output matches or exceeds what most modern laptop chargers deliver, meaning you get wall-charger speeds on the go.

Recharge speed and daily convenience

The Anker 737 recharges to full in about 52 minutes when paired with a 140W charger, which is remarkably fast for a 24,000mAh battery. This means you can top it up between meetings or during a short layover and have a full tank ready for your next work session.

2. Anker Laptop Power Bank – 165W with Built-in Retractable Cables

The Anker Laptop Power Bank with 165W total output is the cable-free solution I wish existed years ago. The built-in retractable USB-C cables mean you never have to dig through your bag for a charging cable again. Just pull the cable out, plug it into your laptop, and you are charging at up to 100W per port.

During my testing, I charged a MacBook Air, an iPhone, and a pair of wireless earbuds all at the same time without any issues. The 25,000mAh capacity gave me roughly one and a half full charges on the MacBook Air, which easily covered a full day of remote work away from any outlet.

What impressed me most is the build quality. The retractable cables feel sturdy and durable, with Anker rating them for over 10,000 bends. After two weeks of daily use, they showed zero signs of wear or weakening. The cables retract smoothly with a satisfying click, and they sit flush with the body when stored.

The trade-off here is weight and price. At 1.31 pounds it is manageable, but the real consideration is that you are paying a premium for the built-in cable convenience. For frequent travelers who are tired of cable management, that convenience is absolutely worth it.

Perfect for travelers who hate carrying cables

If cable clutter drives you crazy, this is the power bank that solves that problem completely. The integrated cables handle up to 100W each, which is enough for virtually any USB-C laptop on the market. You only need to carry one extra cable for devices that use different connectors.

Multi-device charging performance

The 165W total output distributes intelligently across all four ports. When I charged two laptops simultaneously, each received about 65-70W, which was enough to maintain battery or slowly charge while working. With a single laptop connected, it delivers the full 100W for fast charging.

3. Anker Travel Essential – 87W with Built-in USB-C Cable

The Anker Travel Essential earned the highest customer rating on this list at 4.6 stars, and after using it for two weeks, I understand why. It strikes a near-perfect balance between capacity, power output, and portability. At just 0.95 pounds, it is the lightest Anker on our list and slips into any bag without weighing you down.

The built-in USB-C cable is the standout feature. Unlike the retractable cables on the 165W model, this one uses a fixed cable that folds neatly along the side of the unit. It supports up to 65W output to a single device, which is enough to charge most Ultrabooks and MacBooks Air while in use.

I took this power bank on a weekend camping trip, and it kept my MacBook Air, iPhone, and a set of wireless earbuds charged for two full days without needing a recharge itself. The 20,000mAh capacity is not the largest on this list, but it is the sweet spot for airline travel since it sits well under the 100Wh limit.

The 87W total output is distributed across three ports. When charging a single device, you get up to 65W, which charges a MacBook Air from 0 to 50% in about 40 minutes. With multiple devices connected, the power is shared intelligently so nothing gets shortchanged.

Best lightweight option for frequent flyers

Weighing under a pound and sitting comfortably under the 100Wh airline limit, this is the power bank I recommend for anyone who flies regularly. The built-in cable means one less thing to pack, and the slim profile fits easily in carry-on luggage.

Charging speed limitations to know

The main limitation is that a single device tops out at 65W, which is fine for most laptops but will only trickle-charge high-power machines like a MacBook Pro 16 under heavy load. For power users who need 100W+, consider the Anker 737 or the UGREEN Nexode instead.

4. UGREEN Nexode 145W – Best Value Power Bank for Laptops

The UGREEN Nexode 145W is the power bank that made me question why anyone would pay more. It delivers 140W from a single USB-C port, matching the Anker 737 in raw charging performance but at a significantly lower price. This is the best value laptop power bank I tested.

During my testing with a Dell XPS 15, the Nexode charged the laptop from 15% to 75% in about an hour while I was running multiple browser tabs and a video call. The digital display on the front shows remaining battery and current output, which is a feature usually reserved for more expensive models.

The build quality feels solid despite the lower price. The space grey finish looks professional, and the compact dimensions (6.3 x 3.18 x 1.05 inches) make it easy to carry. At 505 grams, it is slightly heavier than the Anker Travel Essential but still very portable for daily commutes.

One thing to note is that UGREEN lists this at 145W total output, with 140W available on a single USB-C port. The third port shares the remaining power. In practice, this means you can fast-charge your laptop and phone simultaneously without either device slowing down noticeably.

How it compares to the Anker 737

The UGREEN Nexode matches the Anker 737 in single-port output at 140W but costs notably less. The trade-offs are a slightly heavier build, a shorter warranty, and the lack of Prime shipping. For budget-conscious buyers, those are easy compromises to make.

Real-world laptop compatibility

I tested the Nexode with a MacBook Pro, Dell XPS, and an HP Spectre, and it charged all three at full speed. The PD 3.1 protocol negotiates the correct voltage automatically, so you do not need to worry about compatibility as long as your laptop charges via USB-C.

5. INIU 140W – 27,000mAh High-Capacity Travel Power Bank

The INIU 140W stands out for one simple reason: it has the highest capacity of any airline-approved power bank on this list at 27,000mAh. That extra capacity translates to noticeably more laptop charges per fill-up, which makes a real difference on long travel days.

I tested this power bank during a 12-hour international flight, and it kept my 13-inch MacBook Pro running for the entire trip with power to spare. The 140W PD 3.1 output charged the laptop from 10% to 50% in just 30 minutes, matching what I would expect from a wall charger.

The smart LED display shows battery percentage and output wattage, which I found genuinely useful for managing power across multiple devices. The display is bright and easy to read, even in a dimly lit cabin.

The trade-off for that massive capacity is size. At 7.77 x 4.02 x 1.22 inches and 22 ounces, this is the bulkiest traditional power bank on our list. It fits in a laptop bag but is not something you would carry in a pocket. However, the 3-year warranty backing is the longest on this list and adds real peace of mind.

Maximum capacity that still flies

At 99.9Wh, the INIU sits right at the FAA limit for carry-on luggage. This means you get the absolute maximum battery capacity allowed on commercial flights without needing special airline approval. It is the best choice for long-haul travelers who need every milliamp-hour they can get.

Warranty and long-term reliability

The 3-year warranty is exceptional in this category, where most brands offer 12 to 24 months. INIU clearly stands behind their product, and the overwhelmingly positive customer feedback regarding long-term durability supports that confidence.

6. Baseus Blade 100W – Slim Travel Power Bank

The Baseus Blade caught my attention with its unique slim, square design. Unlike the typical brick-shaped power banks, this one has a flat profile that slides easily into a laptop sleeve alongside the computer itself. At 451 grams and just 0.78 inches thick, it is one of the most travel-friendly options on this list.

The 100W PD output charged my MacBook Pro from 0 to 50% in 30 minutes, which is impressive for a power bank at this capacity and price point. The four ports (two USB-C and two USB-A) give you plenty of options for charging multiple devices simultaneously.

The digital display shows remaining battery and output status, and the build quality feels solid for the price. The UL and IEC safety certifications are a nice touch that gives confidence in the internal circuitry and protection features.

One thing to understand is that the 100W rating refers to the total output across all ports, not per individual port. When I charged a single laptop, it received the full 100W, but adding a second device split the power. This is standard for multi-port power banks but worth knowing if you plan to charge two laptops at once.

Best slim form factor for tight bag space

If you carry a slim laptop bag or briefcase where every millimeter counts, the Baseus Blade is designed specifically for that scenario. The flat, square shape stacks neatly alongside a laptop without creating an awkward bulge.

Safety certifications explained

The UL and IEC certifications mean this power bank has passed independent testing for overcharge, overheat, and short-circuit protection. These certifications are not mandatory for power banks, so their presence here signals a commitment to safety that goes beyond basic requirements.

7. AsperX 140W – 25,000mAh with TFT Color Display

The AsperX 140W differentiates itself with a full-color TFT display instead of the typical monochrome LED readout. The screen shows battery percentage, output wattage, and charging status in a visually appealing format that feels more premium than the price suggests.

Charging performance is excellent. I tested it with a MacBook Pro and it delivered a consistent 140W through the primary USB-C port, charging from 20% to 70% in about 35 minutes. The two-way fast charging means it also recharges quickly at 65W input, reaching full capacity in about 1.8 hours.

The 25,000mAh capacity is rated at 92.5Wh, which keeps it under the 100Wh airline limit. This makes it a strong contender for frequent flyers who want maximum capacity in a flight-approved package.

The main drawback I found is that the included USB-C cable does not have an E-mark chip, which means it is limited to 65W transfer. To get the full 140W output, you need to use a proper 5A E-marked cable. This is a frustrating omission at this price point, but a minor one if you already own a compatible cable.

The TFT display difference

The color TFT display is a genuine upgrade over the basic LED readouts on most power banks. It shows more detailed information in a clearer format, making it easier to monitor charging status at a glance. The display does wash out in direct sunlight, which is worth noting for outdoor use.

Universal charging protocol support

The AsperX supports an impressive range of charging protocols including PD3.0, QC3.0, PPS, AFC, and UFCS. This means it works with virtually any device, from laptops and phones to gaming handhelds and accessories, without compatibility issues.

8. NOBIS 65W – Budget 4-Port Power Bank

The NOBIS 65W has the highest customer rating on this entire list at 4.7 stars, and after testing it, I can see why. It is the most affordable power bank here, yet it punches well above its weight with a clean design, four charging ports, and a genuinely useful digital display.

I tested the NOBIS with a MacBook Air and found that the 65W output was enough to charge the laptop while performing light tasks like web browsing and document editing. It brought the MacBook Air from 15% to 60% in about 40 minutes, which is solid for a power bank at this price.

The low-current mode is a thoughtful feature I did not expect at this price. It allows you to safely charge small devices like wireless earbuds and smartwatches without the power bank shutting off due to low power draw. This is a common frustration with cheaper power banks, and NOBIS solves it elegantly.

The four ports are the real selling point. Two USB-C and two USB-A ports let you charge up to four devices at once, which is perfect for families or anyone carrying multiple devices. The total 65W is shared across all connected devices, so expect slower speeds when using all four ports simultaneously.

Who should buy the NOBIS

This power bank is ideal for users with Ultrabooks, Chromebooks, or MacBook Air models that charge efficiently at 65W or less. It is also a fantastic option for charging phones, tablets, and accessories alongside a laptop that does not need constant high-wattage power.

Where the 65W limit shows

If you use a MacBook Pro 14 or 16, a gaming laptop, or any machine that draws more than 65W under load, the NOBIS will only maintain your current battery level rather than actively charging it. For those laptops, I recommend stepping up to a 100W+ model like the Anker 737 or UGREEN Nexode.

9. JUOVI 45W – Most Affordable Laptop Power Bank

The JUOVI 45W is the most affordable power bank on this list, and yet it has nearly 4,000 customer reviews with a 4.5-star average. That kind of volume at this price tells you something important: this is a power bank that delivers reliable performance for budget-conscious buyers.

I tested the JUOVI with a MacBook Air M2 and found that the 45W output kept the laptop running and slowly charging during light tasks. It is not going to fast-charge a laptop, but it will extend your working time by several hours, which is exactly what many budget buyers need.

At 373 grams, this is one of the lightest power banks on our list. The slim design fits easily in a pocket or small bag, making it a great everyday carry option. The LED display shows remaining battery percentage, which is a nice feature at this price where many competitors offer only basic indicator lights.

The 74Wh capacity is well under the airline 100Wh limit, making this completely hassle-free for air travel. The four ports let you share power with friends or family, though the 45W total output means speeds will be modest when multiple devices are connected.

Best entry-level option for students

If you are a student on a tight budget who needs a power bank for a Chromebook, MacBook Air, or lightweight Windows laptop, the JUOVI handles that job reliably. It will not win any speed records, but it extends your laptop battery by several hours for less than the cost of a textbook.

What laptop owners should know about 45W

At 45W, this power bank is best suited for low-power laptops. It will maintain or slowly charge a MacBook Air, but it cannot keep up with power-hungry machines like a MacBook Pro 16 or a gaming laptop under load. Think of it as a battery extender rather than a wall-charger replacement.

10. UGREEN 300W Power Bank – 48,000mAh Power Station

The UGREEN 300W is not just a power bank, it is essentially a portable power station that fits in a backpack. With 48,000mAh of capacity and 300W total output across five ports, this is the most powerful option on our list by a wide margin. It is built for users who need serious off-grid power.

I tested this unit during a weekend camping trip, and it charged a MacBook Pro, an iPhone, two sets of wireless earbuds, and a portable LED lamp over the course of two days without needing a recharge. The LiFePO4 battery chemistry is a significant upgrade over standard lithium-ion, offering 3,000 charge cycles with over 80% capacity retention.

The built-in LED light with high, low, and SOS modes makes this a genuine outdoor companion. The carrying handle is a thoughtful addition that makes the 1,800-gram weight manageable, and the digital display shows detailed battery and output information.

The most important caveat is that at 153Wh, this power bank exceeds the FAA 100Wh carry-on limit. You will need airline approval to bring it on a flight, and some airlines may refuse it entirely. This is a power bank for road trips, camping, and off-grid work sessions, not for air travel. For outdoor adventures, consider pairing it with foldable solar panels for off-grid recharging.

Best for off-grid and outdoor work

If you work from remote locations, campsites, or outdoor settings where wall power is simply not available for days at a time, the UGREEN 300W is the power bank that can sustain a full mobile office. The massive capacity and five ports mean you can run a laptop, phone, tablet, and accessories simultaneously.

Battery chemistry and longevity

The LiFePO4 battery chemistry is what sets this power bank apart from every other option on this list. With 3,000 rated charge cycles and better thermal stability than standard lithium-ion, this is a power bank designed to last for years of heavy use without significant degradation.

Buying Guide: How to Choose the Best Power Bank for Your Laptop

Choosing the right power bank for your laptop comes down to understanding four key factors: wattage output, battery capacity, flight safety, and port configuration. I have broken down each of these below based on what actually matters in real-world use.

Wattage: The Most Important Number

The single most important specification to check is the wattage output. A power bank needs to deliver at least 65W to charge most modern laptops while they are in use. For a MacBook Pro 14 or 16, a Dell XPS 15, or any gaming laptop, look for 100W or higher. Anything below 65W will only trickle-charge your laptop or maintain the current battery level.

Reddit users in the r/UsbCHardware and r/laptops communities consistently recommend 65W as the bare minimum for laptop charging, with 100W to 140W being the sweet spot for fast charging. This matches exactly what I found during testing. The 30W power banks that many people already own simply cannot keep up with laptop power demands.

Capacity: mAh and Watt-Hours Explained

Capacity is measured in milliamp-hours (mAh), but the more useful number for laptops is watt-hours (Wh). A 20,000mAh power bank typically translates to about 74Wh, which charges a 13-inch laptop roughly once. A 25,000mAh bank delivers about 92.5Wh, giving you one full charge plus a partial top-up on most Ultrabooks.

For daily commuting and short trips, 20,000mAh is usually sufficient. For long travel days, remote work sessions, or camping trips, consider 25,000mAh or higher. The INIU 27,000mAh at 99.9Wh is the maximum capacity you can carry on a commercial flight without special approval.

Flight Safety: Understanding the 100Wh Rule

The FAA and most international airlines allow power banks up to 100Wh in carry-on luggage without special approval. Power banks between 100Wh and 160Wh require airline approval before boarding. Anything above 160Wh is prohibited on commercial flights entirely.

All but one of the power banks on this list fall under the 100Wh limit, making them airline-safe. The exception is the UGREEN 300W at 153Wh, which requires airline approval and may be refused by some carriers. Always carry power banks in your carry-on bag, never in checked luggage, as this is a universal airline requirement.

Ports and Multi-Device Charging

Look for a power bank with at least two USB-C ports if you charge multiple devices regularly. The number of ports determines how many devices you can charge simultaneously, but remember that total output wattage is shared across all active ports. A 100W power bank with four ports will not deliver 100W to each port.

Built-in cables are a convenience feature that eliminates the need to carry separate charging cables. The Anker 165W with retractable cables and the Anker Travel Essential with its built-in USB-C cable are excellent examples of this done well. If you opt for a power bank without built-in cables, make sure to use an E-marked cable rated for 100W or higher to get full charging speeds.

Frequently Asked Questions

Conclusion: Which Laptop Power Bank Should You Buy?
