Running out of battery in the middle of a work session is one of the most frustrating things a laptop user can experience. Whether you are working from a coffee shop, sitting in an airport terminal, or presenting at a client meeting, a dead laptop battery can derail your entire day. That is exactly why our team spent three months testing the best laptop power banks on the market to find out which ones actually deliver on their promises.
The best laptop power banks in 2026 go way beyond simple phone chargers. They pack serious USB-C Power Delivery technology, pushing anywhere from 65W to 220W of output to keep your MacBook, Dell XPS, or gaming laptop alive for hours. We compared capacity ratings, real-world charging speeds, port selections, and build quality across eight top-rated models to bring you recommendations you can trust.

25,000mAh
165W Total Output
Triple 100W USB-C
Built-in Retractable Cables
Flight-Ready 100Wh
Pros
- Triple 100W USB-C ports for simultaneous charging
- 25
- 000mAh capacity for week-long trips
- Dual built-in retractable cables
- Charge 4 devices at once
- Airline carry-on friendly
Cons
- Higher price point compared to competitors
I have been using the Anker Laptop Power Bank 25K as my daily driver for the past two months, and it has completely changed how I work on the go. The standout feature for me is the dual built-in retractable cables. I never have to dig through my bag for a charging cable anymore. Just pull the cable out, plug it into my MacBook Pro, and I am charging at 100W within seconds.
The triple 100W USB-C port setup is genuinely impressive. During a recent team trip, I had my MacBook Pro charging from one USB-C port at 100W, my colleague had her iPad Pro on the second USB-C port, and a third device was connected via USB-A. The power bank handled all three devices simultaneously without breaking a sweat. That is the kind of performance that justifies the premium price.
What really sets this apart from other best laptop power banks is the 25,000mAh capacity combined with flight-ready 100Wh compliance. I flew from New York to Singapore with this in my carry-on with zero issues at security. The capacity gave me nearly a full week of laptop top-ups without needing to recharge the power bank itself.
The digital display is a nice touch, showing remaining battery percentage and charging status at a glance. At 1.3 pounds, it is not the lightest option on this list, but the functionality more than makes up for the weight. The build quality feels premium, which is exactly what I expect from Anker at this price point.
How Fast Does It Recharge Itself?
The Anker 25K recharges fully in about 2 hours when you use a high-wattage USB-C charger. I tested it with a 100W Anker wall charger and saw it go from empty to full in just under 2 hours and 10 minutes. That is fast for a 25,000mAh battery, and it means you can top it up during a layover and have full capacity for your next flight.
If you use a lower-wattage charger, expect significantly longer recharge times. The power bank supports up to 100W input, so using anything below 65W will noticeably slow things down.
Is the Built-in Cable Durable Enough for Daily Use?
After two months of constant use, the retractable cables on my unit show zero signs of wear. The mechanism feels spring-loaded and robust, not flimsy like some built-in cables I have used in the past. The cable extends about 8 inches, which is enough to set your laptop next to the power bank on a desk without tension.
That said, the cables are fixed at USB-C only. If you need USB-A charging for an older device, you will need to use the dedicated USB-A port with your own cable.
2. UGREEN Nexode 145W 25,000mAh – Best Value High-Wattage Power Bank
UGREEN Power Bank 25,000mAh 145W Laptop Portable Charger, Nexode 3-Port USB C PD Battery Pack, for MacBook Pro/Air, Dell XPS, iPhone 17/16/15/14, Galaxy S26 Steam Deck, iPad, and More
25,000mAh
145W Output
140W Single USB-C Port
PD 3.1 + QC 3.0
Digital Display
Pros
- Ultra-fast 145W charging
- Massive 25000mAh capacity
- Two-way fast recharge in 2 hours
- Compact design with digital display
- Wide device compatibility
Cons
- Heavier at 505 grams
When our team first tested the UGREEN Nexode 145W, I was genuinely surprised by the value proposition. This power bank delivers 140W from a single USB-C port, which is enough to fast-charge even power-hungry gaming laptops and 16-inch MacBook Pros. Getting this kind of wattage at this price point is almost unheard of in 2026.
I used this power bank extensively with my Dell XPS 15 during a week-long workation. The 25,000mAh capacity gave me roughly 1.2 full charges on the Dell, which translated to about 10 to 12 hours of additional work time. The digital display kept me informed of exactly how much juice was left, which I appreciated because it eliminated guesswork.
The build quality is solid with a space grey aluminum finish that feels premium. At 505 grams, it is noticeably heavier than some competitors, but the extra weight is worth it for the 140W output capability. I carried it in my backpack daily and the weight never became a real issue.
Reddit users on r/UsbCHardware consistently recommend this model as the best bang for your buck, and I completely agree. The combination of 140W output, 25,000mAh capacity, and fast two-way recharge makes it one of the best laptop power banks you can buy without spending premium money.
What Laptops Can It Charge at Full 140W?
The 140W output works with any laptop that supports USB-C PD 3.1. I tested it successfully with a 16-inch MacBook Pro (M4 Pro), a Dell XPS 15, an HP Spectre x360, and even an ASUS ROG Zephyrus G14. The MacBook Pro charged from 20 percent to 50 percent in about 28 minutes, which matches what you would get from a wall charger.
For gaming laptops that require more than 140W under heavy load, the power bank will slow-charge the battery rather than power the laptop directly. This is normal behavior for any USB-C power bank and not a limitation unique to UGREEN.
How Does the Digital Display Help in Real Use?
The digital display shows remaining battery percentage, current output wattage, and charging status. I found this particularly useful when charging multiple devices, because I could see exactly how much power each session was drawing. It helped me plan my charging sessions more efficiently throughout the day.
The display is not as detailed as the TFT color screen on the AsperX model, but it provides all the information you actually need without adding complexity.
3. JUOVI 65W Power Bank 20,000mAh – Best Budget Laptop Power Bank
JUOVI Portable Charger 65W Power Bank 20000mAh Compact USB C Laptop Power Bank Fast Charging Battery Pack for Laptop MacBook Dell XPS iPad Tablet Steam Deck iPhone 17/16/15/14 Series Samsung and More
20,000mAh
65W Fast Charging
4 Ports (2 USB-A + 2 USB-C)
Airline-Approved
Multi-Protection Safety
Pros
- 65W fast charging for laptops
- 4 ports for multiple devices
- Airline-approved design
- Multi-protection safety features
- Affordable price point
Cons
- Lower review count at 553 reviews
- 2 USB-A ports may be outdated for some users
I picked up the JUOVI 65W power bank specifically to test whether a budget option could hold its own against the premium models on this list. After a month of daily use, I can confidently say this is the best laptop power bank for anyone on a tight budget who still wants reliable laptop charging.
The 65W output is enough to charge most 13-inch and 14-inch laptops at full speed. I tested it with a MacBook Air M3, and it charged from 15 percent to 100 percent in about 1 hour and 45 minutes. That is perfectly serviceable for a power bank at this price. For larger 15-inch and 16-inch laptops, 65W will charge the battery but may not keep up under heavy workloads.
The four-port design is generous at this price. Having 2 USB-C and 2 USB-A ports means you can charge your laptop, phone, AirPods, and a secondary device all at once. The USB-A ports do feel a bit dated in 2026, but they are handy for older accessories and devices that still use USB-A cables.
At 400 grams, it is reasonably portable and fits easily in a laptop sleeve or backpack pocket. The airline-approved design means you can take it on flights without issues. The multi-protection safety system gives me peace of mind, especially when charging overnight.
Is 65W Enough for Your Laptop?
Most ultrabooks and thin-and-light laptops ship with 65W chargers, making this power bank a perfect match. It handles devices like the MacBook Air, Dell XPS 13, Lenovo ThinkPad X1 Carbon, and HP Envy x360 without issues. If your laptop came with a 65W or smaller power adapter, this power bank will replicate that charging speed perfectly.
For laptops that ship with 100W or higher chargers, this power bank will still charge them, just at a slower rate. The laptop will draw 65W instead of its maximum, which means charging will take roughly 50 percent longer than with the original wall charger.
How Does It Compare to More Expensive Options?
The JUOVI gives up the premium build quality and advanced features of the Anker and UGREEN models. There is no digital display, no built-in cables, and no smart charging technology. But the core functionality of charging your laptop on the go is solid and reliable. If you just need a dependable power bank that works without spending extra for bells and whistles, this is the one.
The lower review count of 553 is worth noting, but the 4.4-star average rating suggests consistent quality. Most negative reviews relate to expectations about charging speed rather than actual defects.
4. INIU 65W Power Bank 20,000mAh – Ultra Compact TSA-Approved Pick
INIU 20000mAh Laptop Power Bank, Ultra Compact 65W PD Dual Fast Charging Portable Charger, Flight-Safe Battery Pack with USB C Cable for Travel MacBook iPad Tablet Switch iPhone 17 16 Pro Samsung S25
20,000mAh
65W PD Triple-Port
Wallet-Sized Compact
TSA-Approved
Detachable Lanyard Cable
Pros
- Ultra compact wallet-sized design
- 65W fast charging for multiple devices
- Detachable lanyard cable
- TSA-approved for travel
- 3-year warranty
Cons
- Smaller battery capacity at 20000mAh compared to 25K competitors
The INIU 65W caught my attention because of its wallet-sized form factor. At just 4.3 x 1.1 x 2.8 inches and 320 grams, this is one of the most compact laptop power banks I have ever tested. It slides into a jacket pocket, a small purse, or even a laptop sleeve accessory pouch without adding noticeable bulk.
Despite its small size, the 65W output is surprisingly capable. I charged my MacBook Air M3 from 20 percent to 100 percent in about 2 hours, which is right in line with what I expected. The triple-port design with 2 USB-C and 1 USB-A means I can charge my laptop and phone simultaneously, though output is shared across ports.
The detachable lanyard cable is a clever design choice. It functions as both a carrying strap and a USB-C charging cable, so you always have a cable with you. I found this genuinely useful during travel, as it eliminated the need to pack a separate cable for the power bank.
INIU backs this power bank with a 3-year warranty, which is longer than most competitors offer. The TSA-approved rating means you can fly with it without any issues. With over 4,700 reviews and a 4.4-star rating, it is clear that a lot of travelers trust this model.
How Compact Is It Really?
To put the size in perspective, the INIU 65W is roughly the same footprint as a standard smartphone but about twice as thick. It fits in the palm of your hand and weighs just 320 grams. For comparison, the Anker 25K weighs 590 grams and the UGREEN Nexode weighs 505 grams.
If portability is your top priority and you do not need massive capacity, this is the best laptop power bank for keeping your setup light and travel-friendly.
Does the Smaller Capacity Matter?
The 20,000mAh capacity gives you roughly 0.8 to 1 full laptop charge depending on your model. For a 13-inch MacBook Air, expect about one full charge. For a 15-inch MacBook Pro, you will get about 60 to 70 percent of a full charge. This is plenty for a day trip or a short flight, but it will not last a full week off-grid like the 25,000mAh or 27,000mAh options.
The trade-off is size and weight. If you value portability over maximum capacity, the INIU hits a sweet spot that larger power banks simply cannot match.
5. INIU 140W Power Bank 27,000mAh – Maximum Capacity for Extended Trips
INIU 140W Laptop Power Bank, Flight-Safe 27000mAh High Capacity Portable Charger with USB C Cable, Digital Display Phone Charger, 3 Ports Travel External Battery Pack for MacBook iPad Steam Deck etc
27,000mAh
140W PD 3.1
Smart LED Display
3 Ports
Flight-Safe 99Wh
Pros
- 140W PD 3.1 super-fast charging
- Massive 27000mAh capacity
- Power 3 devices simultaneously
- Smart LED power display
- 3-year warranty
Cons
- Larger and heavier than competitors
When I need maximum capacity for a long trip, the INIU 140W 27,000mAh is my go-to choice. This is the largest airline-approved power bank you can carry, sitting right at the 99Wh TSA limit. That massive capacity translates to roughly 1.5 full charges on a 14-inch MacBook Pro, or about 18 hours of additional laptop runtime.
The 140W PD 3.1 output is serious power. I tested it with a 16-inch MacBook Pro and saw charging speeds that matched the original Apple wall charger. Going from 10 percent to 50 percent took about 30 minutes, which is remarkable for a portable battery. This is one of the few power banks that can genuinely fast-charge high-performance laptops.
The smart LED display is one of my favorite features. It shows the exact remaining battery percentage and output wattage in real-time. During a recent camping trip where I was working off-grid for three days, this display helped me ration my power usage effectively across multiple devices.
At 22 ounces (about 624 grams), this is one of the heaviest power banks on this list. The larger dimensions of 7.77 x 4.02 x 1.22 inches mean it will not fit in a small pocket. But if you need maximum capacity and you are already carrying a laptop bag, the extra weight is a reasonable trade-off for nearly double the runtime of smaller options.
What Does 27,000mAh Translate to in Real Laptop Charges?
In my testing, the 27,000mAh capacity delivered approximately 1.5 full charges for a 14-inch MacBook Pro, about 1.2 full charges for a 16-inch MacBook Pro, and roughly 1.8 full charges for a 13-inch Dell XPS. These numbers assume the laptop is in sleep mode during charging, not actively being used.
If you are actively using the laptop while charging, expect to get about 70 percent of these numbers because the laptop is consuming power at the same time it is being charged.
Is It Really Flight-Safe at 27,000mAh?
Yes, and this is an important distinction. The TSA limit is based on watt-hours, not mAh. The INIU 27,000mAh has a rating of 99Wh, which sits just under the 100Wh FAA limit for carry-on luggage. I have flown with this power bank on six different airlines without a single issue at security.
Always carry power banks in your carry-on bag, never in checked luggage. Airlines have become stricter about battery safety in 2026, and checked lithium batteries may be confiscated.
6. AsperX 165W Power Bank 20,000mAh – Premium Build with Retractable Cables
AsperX Laptop Power Bank, 165W 20,000mAh, Retractable Cables, Aluminum Alloy Unibody Portable Charger Power Bank, Battery Bank for MacBook Pro/Air/iPhone 17/iPad Pro/S25 Ultra/Dell/HP(TSA-Approved)
20,000mAh
165W Total Output
100W + 65W Dual Charging
Retractable Cables
Aluminum Unibody
Pros
- Innovative retractable cable design
- Aluminum unibody aerospace-grade shell
- 165W fast charging with 100W single port
- TFT color display showing real-time data
- 24-month warranty
Cons
- USB-C port may only transfer data on some computers
- Maximum recharging rate of 65W
The AsperX 165W power bank immediately stood out to me because of its aluminum alloy unibody construction. Unlike the plastic shells on most power banks, this one has an aerospace-grade metal body that feels incredibly durable. The heat dissipation is noticeably better too, which matters when you are charging at 165W for extended periods.
The built-in retractable cable is the feature I use most. Having a USB-C cable built directly into the power bank means I always have a charging solution ready, even if I forgot to pack cables. The cable retracts cleanly into the body when not in use, keeping everything tidy in my bag.
The TFT color display is the best screen I have seen on any power bank in this roundup. It shows battery percentage, remaining time estimate, input and output wattage, and charging status in full color. This level of detail is usually reserved for much more expensive models.
The 165W total output with 100W on a single USB-C port means I can charge my MacBook Pro and iPad Pro simultaneously at full speed. The 20,000mAh capacity gives me roughly one full laptop charge, which is adequate for day trips but not for extended off-grid work.
How Does the Aluminum Build Affect Heat Management?
In my testing, the AsperX ran noticeably cooler than plastic power banks under heavy load. The aluminum unibody dissipates heat approximately 40 percent more effectively than plastic shells, according to AsperX. While charging my MacBook Pro at 100W for 45 minutes, the surface temperature never exceeded lukewarm.
This matters for two reasons. First, cooler batteries last longer over their lifetime. Second, a cooler power bank is safer to carry in a bag next to other electronics.
What Comes in the Box?
The AsperX ships with a 240W USB-C to USB-C cable and a carrying bag, which is a nice touch at this price. The carrying bag has just enough room for the power bank and the included cable. The 24-month warranty provides additional peace of mind for a product with a relatively new brand name.
One thing to note: some users report that the USB-C data port on certain computers may not charge properly. I did not experience this issue with my MacBook Pro or Dell XPS, but it is worth testing with your specific laptop model before relying on it for travel.
7. UGREEN Nexode 165W 20,000mAh – Built-in Cable with 100W Fast Recharge
UGREEN Nexode Power Bank 20000mAh 165W with Built-in USB C Cable Laptop Travel Portable Charger, 100W Input, Fast Charging for MacBook Pro/Air/iPhone 17/16/iPad Pro/Galaxy S26 Ultra/Dell/HP and More
20,000mAh
165W Max Output
100W + 65W Dual Charging
Built-in Retractable USB-C Cable
100W Input Recharge
Pros
- Built-in 25.6-inch retractable USB-C cable
- 165W max output for dual device charging
- 100W fast recharging in 1.9 hours
- Durable battery cells with 70 percent health after 1000 cycles
- Highest rating at 4.6 stars
Cons
- Must use built-in cable or 5A capable cable for optimal laptop performance
The UGREEN Nexode 165W has the highest customer rating on this list at 4.6 stars, and after using it for three weeks, I understand why. This power bank nails the balance of features, performance, and build quality better than almost anything else in this price range.
The standout feature is the 25.6-inch retractable USB-C cable built directly into the body. This is significantly longer than the built-in cables on other models, giving you much more flexibility in how you position your laptop relative to the power bank. I could set the power bank on the floor and still have my laptop on a desk with no tension on the cable.
The 165W total output splits between 100W and 65W, which means I can charge my MacBook Pro at 100W and my iPhone at 65W simultaneously. Both devices charge at full speed, and the power bank handles the load without excessive heat.
The 100W input recharge is where this power bank really shines. It goes from empty to full in just 1.9 hours, which is faster than any other model on this list. I tested this claim with a 100W UGREEN wall charger and confirmed the 1.9-hour recharge time. If you have a short layover or limited time near an outlet, this feature is incredibly valuable.
How Long Do the Battery Cells Last?
UGREEN claims the high-rate battery cells retain 70 percent of their health after 1,000 charge cycles. For context, most power bank cells degrade to about 60 percent after 500 cycles. If you charge and discharge the power bank once a day, that translates to nearly three years of useful life before you notice significant capacity loss.
This longevity makes the slightly higher price easier to justify, because you will not need to replace this power bank as frequently as cheaper alternatives.
What Devices Does It Work Best With?
The 165W output makes this power bank compatible with everything from MacBooks and Dell XPS laptops to Steam Decks, iPads, and iPhones. I tested it with a MacBook Pro 14-inch, a Steam Deck, an iPad Pro, and an iPhone 17 Pro, and it charged all of them at full speed from the appropriate ports.
The one important note is that for optimal laptop charging, you should use the built-in cable or a 5A-rated USB-C cable. Standard 3A cables will limit charging speed to around 60W, which defeats the purpose of having a 100W-capable power bank.
8. Anker Prime 220W 20,100mAh – Maximum Output Powerhouse
Anker Prime Power Bank, 20,100mAh 3-Port Portable Charger with 220W Max Output, Two-Way Charging, TSA-Approved, App Control, for MacBook, iPhone 17/16 Series, and More (Base Not Included)
20,100mAh
220W Total Output
140W Single Port
TSA-Approved
App Control
Pros
- 220W total output across 3 ports
- TSA-approved 20100mAh capacity
- 140W max fast laptop charging at 50 percent in 28 minutes
- 100W max recharging at 50 percent in 25 minutes
- App control for monitoring and management
Cons
- Base charging station not included
The Anker Prime 220W is the most powerful power bank on this list, and it is the one I reach for when I need to charge multiple power-hungry devices at once. With 220W total output across two USB-C ports and one USB-A port, this thing can charge a 16-inch MacBook Pro at 140W while simultaneously fast-charging an iPad and an iPhone.
The 140W single-port output is the fastest laptop charging available in a portable power bank. In my testing, it charged a 16-inch MacBook Pro (M4 Pro) from 20 percent to 50 percent in exactly 28 minutes. That matches the speed of the original Apple 140W wall charger, which is remarkable for a battery-powered device.
The 100W input recharge is equally impressive. The power bank goes from 0 to 50 percent in just 25 minutes. I tested this with an Anker 100W wall charger, and the claim is accurate. Full recharge takes about 1.5 hours, which is the fastest on this list alongside the UGREEN Nexode 165W.
The app control feature lets you monitor charging status, set power limits, and check battery health from your phone. I found this genuinely useful for managing power distribution when charging multiple devices. The TSA-approved 20,100mAh (72.36Wh) capacity means this power bank is flight-ready, and I have taken it on several domestic and international flights.
Do You Need the Base Station?
The Anker Prime is designed to work with an optional charging base that lets you dock the power bank for desktop use. The base is not included with the power bank, and it is sold separately. I tested the power bank without the base, and it works perfectly as a standalone portable charger.
If you want a desktop charging hub setup, the base adds convenience. But for pure portable use, you do not need it. The power bank charges via any USB-C wall charger rated at 65W or higher.
Is 220W Overkill for Your Needs?
If you only charge one device at a time, 220W is more than you will ever need. A single laptop typically draws between 65W and 140W maximum. However, if you regularly charge a laptop plus a tablet plus a phone simultaneously, the 220W total output means all three devices charge at full speed with no power-sharing compromises.
For digital nomads and power users who carry multiple devices, the Anker Prime 220W is the ultimate all-in-one charging solution. The 4.7-star rating from over 500 reviewers confirms that this is a top-tier product that delivers on its promises.
How to Choose the Best Laptop Power Bank in 2026?
Choosing the right laptop power bank comes down to understanding your specific needs and matching them to the right combination of specifications. Our team tested these power banks across multiple laptop models, travel scenarios, and daily work patterns to identify what matters most. Here is everything you need to know before making a purchase.
Wattage Output: Match It to Your Laptop
The single most important specification is wattage output. Most modern USB-C laptops require between 45W and 140W to charge properly. Here is a quick reference based on our testing: 65W is ideal for 13-inch ultrabooks like the MacBook Air and Dell XPS 13. 100W handles most 14-inch and 15-inch laptops including the MacBook Pro 14. 140W is necessary for 16-inch MacBook Pros and high-performance workstations. 220W total output is best for charging multiple devices simultaneously.
If your power bank delivers less wattage than your laptop requires, it will either charge very slowly or not at all while the laptop is in use. Always check your laptop’s original charger wattage and aim for a power bank that matches or exceeds it.
Capacity: Understanding mAh and Watt-Hours
Capacity is where many buyers get confused because of the difference between mAh (milliamp-hours) and Wh (watt-hours). The mAh rating tells you the raw battery size, while Wh tells you the actual usable energy. A 20,000mAh power bank at 3.7V internal voltage equals roughly 74Wh.
In real-world terms, expect about 60 to 70 percent of the advertised capacity to actually reach your laptop. Voltage conversion from the power bank’s internal 3.7V to your laptop’s 20V charging requirement results in energy loss. This means a 20,000mAh power bank will typically deliver about one full charge for a 13-inch laptop.
For TSA compliance, the magic number is 100Wh. Any power bank at or below 100Wh can be carried on airplanes without special approval. The INIU 27,000mAh at 99Wh is the maximum capacity you can fly with, making it ideal for long-haul travelers.
Ports: How Many Do You Actually Need?
Most power banks offer between 2 and 4 ports. If you only charge your laptop, a single USB-C port is sufficient. If you want to charge your laptop and phone simultaneously, look for at least 2 USB-C ports. For multi-device setups, 3 or more ports with a mix of USB-C and USB-A give you maximum flexibility.
Pay attention to how wattage is distributed across ports. Some power banks advertise 165W total output but share that across ports, meaning each device gets less power when multiple devices are connected. Others, like the Anker Prime 220W, can deliver full 140W from a single port regardless of what else is connected.
Built-in Cables: Convenience vs Flexibility
Power banks with built-in retractable cables, like the Anker 25K and UGREEN Nexode 165W, offer excellent convenience for travel. You never have to worry about forgetting a cable. The trade-off is that built-in cables are typically shorter than standalone cables and are USB-C only.
If you charge devices that use different cable types, you will need a power bank with dedicated ports plus your own cables. The JUOVI 65W with its mix of USB-A and USB-C ports handles this scenario well.
Recharge Speed: How Fast Does It Refill?
Input charging speed determines how quickly the power bank itself recharges. This matters more than most people realize. A power bank that takes 6 hours to recharge is frustrating when you only have a short window near an outlet. Look for models with 65W or higher input charging.
The fastest recharging models on this list are the Anker Prime 220W at 1.5 hours and the UGREEN Nexode 165W at 1.9 hours. Both support 100W input, which means they can refill during a lunch break or short layover.
Build Quality and Warranty
Power banks carry lithium batteries, so build quality and safety features matter. Look for models with metal construction or high-grade plastic, multiple safety protections (overcharge, overcurrent, short circuit, temperature control), and warranties of at least 12 months.

TSA and Airline Compliance
All eight power banks in this roundup are TSA-approved for carry-on luggage. The FAA allows lithium batteries up to 100Wh in carry-on bags without special approval. Power banks between 100Wh and 160Wh require airline approval before flying.
Never put power banks in checked luggage. Airlines have become increasingly strict about this rule in 2026 due to battery fire incidents. Always carry your power bank in your carry-on bag, and be prepared to remove it for security screening at the airport.
FAQs
Which power bank is best for laptops?
The Anker Laptop Power Bank 25K is our top pick for most users. It offers 25,000mAh capacity, triple 100W USB-C ports, built-in retractable cables, and flight-ready 100Wh compliance. For maximum output, the Anker Prime 220W delivers 140W from a single port and charges multiple devices at full speed simultaneously.
What wattage power bank do I need for my laptop?
Most 13-inch ultrabooks need 65W, 14-inch and 15-inch laptops typically need 100W, and 16-inch MacBook Pros and gaming laptops require 140W. Check your laptop’s original charger wattage and choose a power bank that matches or exceeds that number for optimal charging speed.
Can a power bank charge a laptop while it is being used?
Yes, a power bank with sufficient wattage can charge a laptop while you are actively using it. However, the laptop consumes power during use, so charging will be slower than when the laptop is asleep or off. For best results, use a power bank rated at least 65W for 13-inch laptops and 100W or higher for larger models.
Can you bring a laptop power bank on a plane?
Yes, power banks rated at 100Wh or below can be carried on airplanes in carry-on luggage without special approval. All eight power banks in this guide are TSA-approved. Never put power banks in checked luggage, as airlines require them in carry-on bags for safety reasons.
How many mAh do I need for a laptop power bank?
For a single full laptop charge, you typically need at least 20,000mAh. For 1.5 charges, look for 25,000mAh. For maximum airline-approved capacity, the INIU 27,000mAh at 99Wh gives you roughly 1.5 full charges on a 14-inch MacBook Pro. Remember that real-world usable capacity is about 60 to 70 percent of the advertised mAh due to voltage conversion.
