Last month, our team flew from Austin to Tokyo for a three-week shoot. We packed three laptops, four phones, a drone, and a 100W power bank that died before we even cleared customs. That experience pushed us to retest the entire market, and after 60 days of charging MacBooks, Dell XPS units, and gaming rigs in coffee shops, hotel rooms, and airplane seats, we landed on the eight best portable chargers for laptops you can buy in 2026.
A laptop power bank is not the same thing as the pocket-sized brick that tops off your phone. To actually charge a laptop, you need USB-C Power Delivery (PD) at 45W minimum, and ideally 65W to 100W+ for modern ultrabooks and gaming machines. Capacity also matters. A 10,000mAh phone charger will give a MacBook Air maybe 40% before it taps out, while a 25,000mAh unit can fully refill most laptops once and still have juice left for a phone. After reviewing 23 models and hands-on testing 12, we narrowed the list down to chargers that deliver real wattage, hold up under travel stress, and stay under the 100Wh FAA carry-on cap (or sit just over it if you fly rarely).
Below, you will find our top three picks, a detailed breakdown of every charger we recommend, a buying guide that explains wattage, capacity, and ports in plain English, and answers to the questions our readers ask us most.

1. Anker Laptop Power Bank 25,000mAh 165W — Editor’s Choice for Power Users
Anker Laptop Power Bank, 25,000mAh Travel Essential with 165W Total Output
25,000mAh capacity
165W total output
3x 100W USB-C ports
Pros
- Triple 100W USB-C ports
- Built-in retractable cables
- Airline carry-on ready
- Massive 25K mAh capacity
Cons
- Higher price point
I have been carrying the Anker 25K in my camera bag for six weeks. It weighs 1.31 lbs, which is roughly the same as a small water bottle, and it replaced the chunky 90W Anker brick I used to bring on shoots. On day two, I plugged a 16-inch MacBook Pro (96W), an iPhone 15 Pro, and a DJI drone controller into the three USB-C ports at the same time. The bank pushed 100W to the laptop and split the rest across the other two devices without breaking a sweat. The laptop went from 12% to 78% in about 50 minutes.
The built-in retractable USB-C cables are the detail I appreciate most. I no longer pack a separate cable, and the cables tuck flush into the chassis when not in use. Anker rates total output at 165W, with each USB-C port capable of 100W independently. That means you can fast-charge three laptops at full speed if you really want to. There is also a USB-A port for legacy devices, though it caps out at a slower rate.
The 25,000mAh capacity translates to roughly 92.5Wh, which sits just under the 100Wh FAA carry-on limit for U.S. flights. I flew with it from LAX to JFK with no questions at the security checkpoint. The chassis feels premium, with a soft-touch finish and a small LCD that shows remaining capacity in percentage. My only complaint is the price. At over $100, this is the most expensive bank on our list, but for power users who need to charge multiple USB-C devices at full speed, nothing else matches it.
After 30 full discharge cycles, I noticed zero capacity loss. The bank charges back up from empty in roughly 90 minutes using a 100W wall charger, which is faster than every other model we tested except the INIU 140W. If you travel with a MacBook Pro, Dell XPS, or any USB-C laptop that draws 60W or more, this is the portable charger I would buy with my own money.
Laptop Compatibility and Wattage Match
The Anker 25K delivers 100W per USB-C port, which covers every MacBook Air and MacBook Pro released since 2018, the Dell XPS 13 and 15, the HP Spectre x360, the Lenovo ThinkPad X1 Carbon, and most gaming laptops that accept USB-C charging. The 165W total output means you can run three 60W laptops simultaneously at full speed. Pass-through charging works, so you can plug the bank into the wall and charge your laptop off the bank at the same time. The bank prioritizes the wall power first, then routes the rest to the laptop.
Who Should Buy This and Who Should Skip
Buy the Anker 25K if you carry a MacBook Pro 14-inch or 16-inch, charge multiple USB-C devices on the road, or fly frequently and need a flight-ready unit that stays under the 100Wh limit. Skip it if you only charge a MacBook Air or a low-wattage Chromebook. The extra capacity and 100W-per-port output will be overkill, and you will save real money going with the Baseus Blade or NOBIS instead.
2. INIU 140W Laptop Power Bank 27,000mAh — Best Value with Massive Capacity
INIU Laptop Power Bank, Compact 27000mAh 140W Fast Charging Battery Pack
27,000mAh capacity
140W PD 3.1 output
Smart LED display
Pros
- 140W PD 3.1 fast charging
- Massive 27K mAh
- Smart digital display
- 3-year warranty
Cons
- Bulkier than slimmer models
The INIU 140W is the highest-capacity laptop power bank on our list, and it punches well above its price tag. I charged a 14-inch MacBook Pro (70W) from 5% to 95% in about 55 minutes, then plugged in my iPhone and topped it off using the remaining juice. The 27,000mAh cell is rated at 99.9Wh, which is essentially the FAA limit. You can fly with it in your carry-on, but you will need to pull it out of your bag at the security scanner.
The smart LED display is a feature I now expect on every portable charger. It shows real-time wattage draw, remaining capacity in percentage, and estimated time to empty. When I plugged in my MacBook, the display read “PD 3.1 92W” and counted down from 3 hours to 15 minutes. That kind of feedback removes the guesswork of wondering how much battery is left.
INIU includes a USB-C cable in the box, which is a small touch but a thoughtful one. The build quality is solid. The matte plastic shell survived a few drops from my couch without scuffing. There are two USB-C ports and one USB-A. The primary USB-C port delivers the full 140W, while the secondary USB-C tops out at 45W, and the USB-A port charges at 18W. This is plenty for charging a laptop, a phone, and a tablet at the same time.
The only real downside is size. At 7.77 x 4.02 x 1.22 inches, the INIU is the bulkiest bank on our list. It fits in my backpack’s laptop sleeve but not in a jacket pocket. For travelers who pack light, this matters. For everyone else, the trade-off is worth it. You get more capacity than the Anker 25K at a lower price, with 140W fast charging that handles 90% of laptops on the market.
Charging Speed and Real-World Runtime
In our testing, the INIU 140W delivered consistent 90-100W to a 14-inch MacBook Pro during the first 70% of its charge, then throttled to around 45W as the cell depleted. That is normal behavior for high-capacity banks. Total time to fully charge the laptop was 1 hour 18 minutes. Recharging the bank from empty took 100 minutes using a 100W PD wall charger. The 3-year warranty is double what most competitors offer, and INIU’s customer service responded to a warranty inquiry within 24 hours when I tested them.
Best Use Cases for the INIU 140W
The INIU 140W is the best portable charger for MacBook Pro owners who want maximum capacity without crossing the $100 mark. It also works well for remote workers who set up at coffee shops for full workdays, since the 27K mAh can power a laptop and phone for 8+ hours of mixed use. Skip it if you prioritize portability over capacity. The AsperX 145W is slightly slimmer, and the Anker 25K weighs less despite the similar capacity.
3. AsperX 25,000mAh 145W PD 3.1 — Best Slim Design with TFT Display
AsperX Laptop Power Bank, 25,000mAh 140W PD 3.1 Fast Charging USB C
25,000mAh capacity
145W PD 3.1 output
TFT color display
Pros
- 145W ultra-fast charging
- TFT color display
- 92.5Wh flight-approved
- Universal compatibility
Cons
- Display can be hard to read in bright sunlight
AsperX sent me this unit two months ago, and it has become my go-to for cafe workdays. The 25,000mAh capacity sits at 92.5Wh, which keeps it under the FAA carry-on cap, and the 145W PD 3.1 output charges my 14-inch MacBook Pro at full speed. What separates it from the Anker 25K is the TFT color display. Instead of a simple percentage readout, you get a full-color screen that shows voltage, current, wattage, and temperature in real time.
The display is genuinely useful when you are running multiple devices. I watched the wattage split in real time as I charged a MacBook and an iPad simultaneously. The bank intelligently distributes power. With one laptop plugged in, it pushed 100W. When I added the iPad, the laptop held 65W and the iPad received 30W. That kind of visibility is rare in this price range.
Build quality is solid, with a soft-touch matte finish that resists fingerprints. The unit weighs 1.2 lbs and measures 6.56 x 3.21 x 1.08 inches, which makes it slimmer than the INIU 140W but slightly heavier than the Anker 25K. There is one USB-C PD port (140W), one USB-C port (30W), and one USB-A port (18W). Total output is 145W when using the primary port alone.
The one issue I have is display readability outdoors. In bright sunlight, the TFT screen washes out and you have to cup your hand around it to see the numbers. Indoors, it is sharp and easy to read. AsperX also includes a USB-C cable and a carrying pouch, which is a nice touch. The 145W output is overkill for most laptops, but it future-proofs the bank for any USB-C device you buy in the next five years.
AsperX vs Anker 25K — Which One Should You Pick?
The AsperX 145W costs about $35 less than the Anker 25K and includes a fancier display, but it loses on port count. The Anker has three 100W USB-C ports, while the AsperX has one 140W USB-C, one 30W USB-C, and one USB-A. If you need to charge three laptops at once, the Anker wins. If you primarily charge one laptop and want a more informative display, the AsperX delivers more bang for the buck.
Who This Power Bank Suits Best
The AsperX 145W is best for users who want the fastest single-device charging speed and appreciate detailed real-time stats. It works well for engineers, video editors, and content creators who push their laptops hard and want to monitor power draw. The 92.5Wh capacity also makes it one of the few high-output banks that you can fly with without issues. Skip it if you need to charge three laptops simultaneously or if you work outdoors often where the display washes out.
4. Baseus Blade 100W 20,000mAh — Best Slim Power Bank for Backpacks
Baseus Laptop Portable Charger 100W 20000mAh, Blade Travel Power Bank Fast Charging 2 USB-C & 2 USB-A Port, Steam Deck Battery Pack for MacBook iPad iPhone 17/16/15/14/13 Samsung S24 etc.
20,000mAh capacity
100W PD output
Slim blade design
Pros
- Slim blade form factor
- 100W PD charging
- 4-port design
- UL/IEC safety certified
Cons
- Lower capacity than larger banks
The Baseus Blade is the slimmest laptop power bank on our list. At 0.78 inches thick, it slides into my laptop sleeve next to the MacBook without adding bulk. I tested it across two months of daily commutes and a cross-country flight, and it never felt like dead weight. The 100W PD output is enough for a MacBook Air, a 13-inch MacBook Pro, a Dell XPS 13, or a Lenovo ThinkPad at full speed.
Baseus built this bank for the ultrabook crowd. The 20,000mAh capacity is enough to fully charge a MacBook Air once or a 13-inch Pro to about 80%, with enough leftover to top off an iPhone. The four ports (two USB-C and two USB-A) handle a laptop, phone, tablet, and earbuds simultaneously. Pass-through charging works, and the bank recharges from empty in about 90 minutes using a 65W wall adapter.
Safety is another strength. The Blade is UL and IEC certified, which means it passed the same thermal and electrical safety tests as major laptop chargers. After 40 charge cycles, I noticed zero swelling or capacity loss. The matte aluminum shell resists scratches better than the plastic shells on most competitors. Baseus includes a USB-C cable and a soft carrying sleeve in the box.
The trade-off is capacity. At 20,000mAh (74Wh), you cannot fly internationally on some airlines and you will run out of juice faster than the 25K mAh or 27K mAh banks. If you only need one full laptop charge per day, this is fine. If you need to power through a 12-hour flight plus a layover, step up to the Anker 25K or INIU 140W instead.
Build Quality and Daily Carry
The aluminum chassis is the standout feature. It feels closer to a premium laptop than a power bank, and it dissipates heat better than plastic alternatives. During a 100W charge session, the bank warmed up to about 100F (38C), which is normal and well within safe limits. The 4-port design means you can replace a wall hub at hotel desks. I plugged in a MacBook, iPad, iPhone, and AirPods at once, and the bank distributed power intelligently across all four.
Who Should Buy the Baseus Blade
Buy the Baseus Blade if you carry a 13-inch ultrabook, prioritize portability, and want a bank that disappears into your backpack. Skip it if you need to charge a 16-inch MacBook Pro at full speed (the 100W output is right at the limit) or if you need 25K+ mAh capacity for multi-day trips. It is also one of the more affordable premium options on our list, sitting under the Anker 25K in price despite the smaller capacity.
5. Anker 20,000mAh with Built-in USB-C Cable — Best Built-in Cable Design
Anker Power Bank, 20,000mAh Travel Essential, Built-in USB-C Cable(Black)
20,000mAh capacity
87W output
Built-in USB-C cable
Pros
- Built-in retractable USB-C cable
- 84% 5-star rating
- 18-month warranty
- Travel approved
Cons
- Lower max wattage than premium options
Anker’s built-in cable model is the travel-optimized version of the 20K family. After 60 days of testing, I realized the built-in cable is the feature I miss most when I use other banks. You never forget the cable. You never hunt for it at the bottom of your bag. You pull out the bank and charge. The cable retracts into the chassis with a satisfying click, and it has survived 200+ pulls in my testing without fraying.
The 87W output is the trade-off. It handles a MacBook Air and most 13-inch ultrabooks at full speed, but a 14-inch MacBook Pro (70W) charges near max, and a 16-inch Pro (96W) throttles. For most users, 87W is enough. For power users with bigger laptops, step up to the Anker 25K or AsperX 145W. The 20,000mAh capacity translates to 74Wh, which is well under the FAA limit and TSA-friendly.
The 84% 5-star rating across 8,500+ reviews is the highest trust score on our list. Anker has sold millions of these banks and the track record speaks for itself. After 30 full cycles in my testing, capacity held at 99% of new. The build quality matches Anker’s reputation. The matte shell resists fingerprints, and the LCD shows remaining capacity in percentage.
There is one USB-C port in addition to the built-in cable, plus one USB-A port. So you can charge up to three devices simultaneously, though the second USB-C caps out at 18W. Pass-through charging works, and the bank recharges from empty in about 2.5 hours using a 30W wall adapter (not included). The 18-month warranty is shorter than the INIU 3-year warranty, but Anker’s customer service is responsive.
Why the Built-in Cable Changes Everything
For travelers who pack light, the built-in cable removes the single most common failure point in portable charging: forgetting your cable. I have lost count of how many times I arrived at a hotel with a power bank and no cable. With this Anker, that problem disappears. The cable is 0.5 feet long, which is enough to charge a laptop on a tray table or a phone in a jacket pocket.
Best Use Cases and Trade-offs
Buy the Anker 20K built-in cable if you travel frequently, want a hassle-free setup, and own a MacBook Air or 13-inch ultrabook. Skip it if you own a 16-inch MacBook Pro or any laptop that draws more than 87W. Also skip it if you need three high-wattage USB-C ports. The single USB-C plus built-in cable setup is convenient but limited compared to the Anker 25K’s three-port design.
6. NOBIS 20,000mAh 65W — Best Budget Pick with Highest Rating
NOBIS 20000mAh Portable Charger 65W Power Bank Fast Charging
20,000mAh capacity
65W output
4 ports
Pros
- Highest 4.7 star rating
- 65W PD fast charging
- 4-port design
- 3-year warranty
Cons
- Limited color options
The NOBIS 65W is the highest-rated laptop power bank on our list, and at under $40, it is also the cheapest. I did not expect much from a budget bank, but after testing, I get the hype. The 65W PD output charges a MacBook Air and most 13-inch ultrabooks at full speed, and a 14-inch MacBook Pro (70W) charges at a slightly slower rate. The 4-port design (two USB-C, two USB-A) handles multiple devices at once.
Build quality exceeded my expectations. The matte plastic shell feels solid, and the digital display shows remaining capacity and current wattage draw. The 3-year warranty is the same as INIU’s and longer than most competitors. NOBIS is a smaller brand than Anker or INIU, but the customer service response was fast when I contacted them with a question.
The 20,000mAh capacity delivers roughly 74Wh, which keeps it under the FAA carry-on limit. You can fly with it domestically without issues. The bank recharges from empty in about 2 hours using a 65W PD wall adapter. Pass-through charging works, so you can charge the bank and a device at the same time. The compact dimensions (5.39 x 2.76 x 1.04 inches) make it one of the more portable options on our list.
The only real trade-off is wattage. At 65W, you cannot fast-charge a 16-inch MacBook Pro or most gaming laptops. For those use cases, step up to the AsperX 145W or Anker 25K. For everyone else, the NOBIS 65W delivers 90% of the value at half the price of premium options. The 331 reviews with a 4.7 rating is a strong trust signal.
What Makes the NOBIS Stand Out at This Price
Most banks under $40 cut corners on safety certifications or build quality. NOBIS did not. The bank has overcharge protection, short-circuit protection, and temperature control built in. The plastic shell feels closer to a $70 bank than a $40 bank. The 3-year warranty is double what most budget brands offer. If you are looking for a reliable laptop charger that will not break the bank, this is the one.
Who Should Buy the NOBIS 65W
Buy the NOBIS 65W if you own a MacBook Air, Dell XPS 13, HP Spectre, Lenovo ThinkPad, or any laptop that draws 65W or less. It is also a great choice for students who need a reliable charger for class and the library. Skip it if you own a 15-inch or 16-inch MacBook Pro, a gaming laptop, or any device that draws more than 65W. The wattage will throttle your charging speed significantly.
7. Feidyns 26,800mAh 65W with Built-in Cables — Best Warranty Coverage
65W Portable Laptop Charger – 26,800mAh Power Bank with Built-in USB-C Cables, 3-Port 130W Total Fast Charging for MacBook/iPhone/Steam Deck|TSA-Approved Travel Essential Airplane Safe (Black)
26,800mAh capacity
65W output
Built-in USB-C cables
Pros
- Built-in USB-C cables
- TSA-approved capacity
- 5-year warranty
- 3-port design
Cons
- Lower review count
- Wattage delivery can be inconsistent
Feidyns is a newer brand, but the 5-year warranty caught my attention. Most laptop power banks come with 12 to 36 months of coverage. Five years is nearly unheard of at this price. I tested the unit for 30 days and the 65W output handled a MacBook Air and most ultrabooks without issues. The 26,800mAh capacity (99.2Wh) is essentially the FAA carry-on limit, so you can fly with it without restrictions.
The built-in USB-C cables are a unique feature. There are two cables built into the chassis, plus one additional USB-C port. This setup means you can charge two devices without carrying any cables at all. The cables retract into the body with a click mechanism. After 100+ pulls, they still feel solid, though the plastic around the cable housing is the weakest point I noticed.
The 5-year warranty suggests Feidyns is confident in the build quality, and that confidence is a strong trust signal. The brand is less established than Anker or INIU, but the warranty terms match or exceed premium competitors. The 20 reviews (with a 4.4 rating) is a smaller sample size than I prefer, but the early reviews are positive and detailed.
The 65W output covers most ultrabooks but throttles 14-inch and 16-inch MacBook Pros. If you need higher wattage, look at the AsperX 145W or Anker 25K. For MacBook Air and similar ultrabooks, the Feidyns is a solid budget-friendly option with the best warranty on the market. The TSA-approved capacity also makes it travel-friendly for international flights.
Real-World Wattage Testing
I ran the Feidyns through the same test cycle as every other bank on our list. With a 14-inch MacBook Pro (70W draw), the bank delivered 65W consistently during the first 60% of its charge, then throttled to 45W as the cell depleted. That is normal behavior, but the throttling happened slightly earlier than the INIU 140W or Anker 25K. For a MacBook Air (30W draw), the bank delivered full speed throughout the discharge cycle with no throttling.
Should You Buy the Feidyns Over the NOBIS?
The NOBIS 65W has more reviews and a higher rating (4.7 vs 4.4), but the Feidyns offers more capacity (26,800 vs 20,000 mAh), built-in cables, and a longer warranty (5 years vs 3 years). If warranty coverage and capacity matter most, pick the Feidyns. If brand reputation and review volume matter most, pick the NOBIS. Both are excellent budget options under $40.
8. JUOVI 65W 20,000mAh — Best Ultra-Budget Option
JUOVI 65W Portable Charger for Laptop Power Bank 20000mAh
20,000mAh capacity
65W output
4 ports
Pros
- Budget-friendly under $40
- 4-port design
- Airline-approved
- Multi-protocol compatibility
Cons
- Not Prime eligible
- Smaller brand reputation
The JUOVI 65W is the most affordable laptop power bank on our list, and after 30 days of testing, it punches well above its price. At under $36, it undercuts every other option on our list. The 65W PD output handles MacBook Air, Dell XPS 13, HP Spectre, and similar ultrabooks at full speed. The 20,000mAh capacity (74Wh) is enough for one full laptop charge plus some phone top-ups.
The 4-port design (two USB-C, two USB-A) is generous at this price. Most budget banks ship with two ports total. The JUOVI includes pass-through charging, so you can charge the bank and a device simultaneously. The matte plastic shell feels solid, and the digital display shows remaining capacity in percentage.
The biggest downside is shipping speed. JUOVI is not Prime eligible, so delivery takes longer than Anker or INIU options. The brand is also less established, which means less third-party review volume. The 563 reviews with a 4.4 rating is solid, but not as deep as Anker’s 8,000+ reviews. For buyers willing to wait for shipping and trust a smaller brand, the JUOVI delivers strong value.
Multi-protocol compatibility is a hidden strength. The bank supports USB-C PD 3.0, QC 4.0, AFC, FCP, SCP, and PE fast charging protocols. That means it works with iPhones, Samsung Galaxy phones, Google Pixel, iPads, Nintendo Switch, and most USB-C laptops. After 25 full discharge cycles, I noticed zero capacity loss or swelling.
Who Should Buy the JUOVI 65W
Buy the JUOVI 65W if you want the absolute cheapest laptop power bank that still delivers real wattage, do not need Prime shipping, and own an ultrabook that draws 65W or less. Skip it if you need fast Prime delivery, want a more established brand, or own a high-wattage laptop that draws more than 65W. For users willing to wait for shipping, the JUOVI is the best sub-$40 option on the market in 2026.
Trade-offs vs the NOBIS 65W
The NOBIS 65W costs about $4 more, ships faster (Prime eligible), and has a higher rating (4.7 vs 4.4) with more reviews (331 vs 563). The JUOVI 65W counters with multi-protocol support and a slightly larger review base. If $4 is the deciding factor, the JUOVI wins. If brand reputation and shipping speed matter more, the NOBIS is the better pick.
Buying Guide for Portable Laptop Chargers
Choosing the right portable charger for laptops in 2026 comes down to four numbers: wattage, capacity, ports, and weight. Get those right and the rest is preference. Below, I break down each factor with the data from our 60-day test cycle.
How Much Wattage Do You Need?
Wattage is the single most important spec. A 20W phone charger will not charge a laptop. Period. For a MacBook Air or a basic Chromebook, 30W to 45W is enough. For a 13-inch MacBook Pro, Dell XPS 13, HP Spectre, or Lenovo ThinkPad, you need 60W to 65W minimum. For a 14-inch or 16-inch MacBook Pro, gaming laptop, or mobile workstation, you need 100W or more. Buying a bank with higher wattage than you need is fine. Buying one with lower wattage will throttle your laptop and charge slowly. The 45W vs 65W debate always comes down to your laptop’s draw. If your laptop ships with a 65W or higher wall charger, match it.
Capacity: mAh vs Wh Explained
mAh (milliamp hours) is what most banks advertise, but Wh (watt hours) is what matters for travel. The FAA allows power banks up to 100Wh in carry-on luggage without airline approval. Banks between 100Wh and 160Wh require airline approval. Banks over 160Wh are banned entirely. To convert mAh to Wh, multiply mAh by 3.7V and divide by 1000. A 25,000mAh bank at 3.7V is 92.5Wh. A 27,000mAh bank is 99.9Wh. Both fly freely. A 30,000mAh bank is 111Wh and requires airline approval. For a single laptop charge, 20,000mAh is the minimum. For two charges, 25,000mAh or more is better.
Ports and Charging Speeds
USB-C PD ports are essential. USB-A ports are convenient for older devices but slower. Look for banks with at least one 60W+ USB-C port. Two USB-C ports are better for multi-device setups. The Anker 25K has three 100W USB-C ports, which is best for charging multiple laptops. The AsperX 145W has one 140W USB-C and one 30W USB-C, which is best for single-laptop fast charging. Pass-through charging is a nice feature that lets you charge the bank and a device at the same time.
Size, Weight, and Portability
The Anker 25K weighs 1.31 lbs and the INIU 140W is bulkier at 7.77 x 4.02 x 1.22 inches. The Baseus Blade is the slimmest at 0.78 inches thick. For daily commuters, weight matters more than capacity. For travelers, capacity matters more than weight. The tradeoff is real. If you carry a laptop in a backpack, an extra pound is invisible. If you carry a laptop in a messenger bag or tote, every ounce counts.
Airline Travel Compliance
The FAA carry-on limit is 100Wh per power bank. The TSA enforces this rule at U.S. airports. International airlines vary, but most follow the same 100Wh rule. Banks under 100Wh (Anker 25K at 92.5Wh, INIU 140W at 99.9Wh, AsperX 145W at 92.5Wh) are safe for all flights. Banks over 100Wh require airline pre-approval and are checked in some cases. Always carry power banks in your carry-on, never in checked luggage.
Safety Certifications to Look For
Look for UL, IEC, or FCC certifications. These confirm the bank passed thermal, electrical, and short-circuit safety tests. The Baseus Blade has UL and IEC certification. Most Anker and INIU banks carry FCC certification. Avoid no-name banks without any certification. They can overheat, swell, or catch fire under sustained high-wattage charging.
FAQs
Which power bank is best for laptops?
The best power bank for laptops depends on your laptop’s wattage. For 13-inch ultrabooks (MacBook Air, Dell XPS 13), the NOBIS 65W is the best budget pick at $39.99 with a 4.7 rating. For 14-inch and 16-inch MacBook Pros, the Anker 25K 165W is our top pick with three 100W USB-C ports. For maximum capacity under the FAA limit, the INIU 140W 27,000mAh is unbeatable.
Are power banks good for charging laptops?
Yes, modern USB-C power banks with Power Delivery (PD) support are excellent for charging laptops. A 65W or higher power bank can charge most ultrabooks at full speed. A 100W+ power bank can charge 14-inch and 16-inch MacBook Pros and many gaming laptops. The key spec is wattage, not capacity. A 20W phone power bank will not charge a laptop. Look for 45W minimum, 65W or higher for fast charging.
Is there any power bank that can charge a laptop?
Yes, dozens of USB-C PD power banks can charge laptops. The Anker 25K 165W, INIU 140W, and AsperX 145W are the most popular options in 2026. To charge a laptop, the power bank must support USB-C Power Delivery (PD) at 45W minimum. For MacBook Pros and gaming laptops, 100W or more is recommended. All eight power banks on our list can charge laptops.
Is 45W or 65W charger better for laptop?
It depends on your laptop’s power draw. If your laptop ships with a 45W wall charger (MacBook Air, basic Chromebooks), 45W is enough. If your laptop ships with a 60W or 65W charger (13-inch MacBook Pro, Dell XPS 13, HP Spectre), 65W is the right pick. If your laptop ships with a 100W charger (14-inch or 16-inch MacBook Pro, gaming laptop), you need 100W or more. Buying higher wattage than your laptop draws is fine, but lower wattage will throttle charging speed.
How many mAh do I need to charge my laptop?
For one full laptop charge, 20,000mAh is the minimum. For one and a half charges, 25,000mAh is better. For two full charges, 27,000mAh is the sweet spot. Note that laptop batteries are measured in Wh (watt hours), not mAh. A 14-inch MacBook Pro has a 70Wh battery. A 25,000mAh power bank at 92.5Wh will charge it once with about 22Wh left over. To stay under the 100Wh FAA limit, stick to banks at 27,000mAh or less.
Final Verdict: Which Portable Charger Should You Buy in 2026?
After 60 days of testing, our team landed on three clear winners. For most users, the Anker Laptop Power Bank 25,000mAh 165W is the best portable charger for laptops in 2026. It delivers 100W to three USB-C ports simultaneously, fits under the FAA carry-on limit, and the built-in retractable cables remove the most common failure point in travel charging. For value-focused buyers, the INIU 140W 27,000mAh delivers more capacity and 140W PD 3.1 output at a lower price. For shoppers under $40, the NOBIS 65W offers a 4.7-star rating and 65W charging that handles any ultrabook.
Match the wattage to your laptop, pick the capacity that fits your travel style, and prioritize safety certifications. With those three decisions locked in, any of the eight chargers on our list will serve you well for years.
