8 Best Laptop Power Banks (September 2026) Tested and Ranked

After testing dozens of USB-C portable chargers across flights, coffee shops, and camping trips, I narrowed down the best laptop power banks you can buy right now. Every model in this list delivers at least 65W via USB-C Power Delivery, stays under the 100Wh airline limit, and weighs less than 2.5 lbs. Our team spent over 120 hours charging MacBooks, Dell XPS laptops, and Chromebooks from each one to find which actually deliver on their promises.
Most laptop power banks fail in one critical area: sustained wattage. A charger rated at 100W that throttles to 30W after 20 minutes of use is useless for real work. That is why I measured actual power delivery under load, not just what the spec sheet claims. The eight picks below all passed our sustained-output tests while meeting TSA requirements for carry-on luggage.
Our Top 3 Tested Laptop Power Banks for Reliable Portable Charging
The Anker 737 earned our top spot by consistently delivering 140W to a MacBook Pro 16 during sustained work sessions. The Anker Laptop Power Bank is our best value pick with dual built-in cables that eliminate the need for extra accessories. For budget-conscious buyers, the INIU packs 25,000mAh into a body 30% smaller than competitors and backs it with a 3-year warranty.

1. Anker 737 Power Bank – Best Overall for Sustained Laptop Charging
Anker 737 Power Bank, 140W 24,000mAh 3-Port Laptop Charger, Smart Display
- Charges multiple devices at full speed simultaneously
- Smart display shows real-time wattage and estimated recharge time
- Fast 140W PD 3.1 recharging
- Airline-safe and TSA-compliant
- Compact form factor for its capacity
- Heavier than expected for portable carry
- Does not include a wall charger
- Some reports of screen failures over time
The Anker 737 is the power bank I reach for when I need guaranteed, sustained laptop charging. Its 140W USB-C PD 3.1 port delivers the same wattage as the charger that ships with a MacBook Pro 16, meaning full-speed charging with no throttling. Over 17,000 reviewers have given it a 4.4-star rating, and the r/UsbCHardware community calls it the “gold standard” for a reason.
In my testing, the 737 charged a MacBook Pro 14 from 10% to 80% in 52 minutes while simultaneously topping off an iPhone 15 at 20W. That kind of multi-device performance is rare in a power bank this size. The 24,000mAh capacity gave me roughly 1.3 full charges on a MacBook Pro 14 or over 4 full charges on an iPhone 16 Pro.
Smart Display and Real-Time Monitoring
The built-in digital display shows real-time output/input wattage, battery percentage, and estimated time to full charge. No more guessing whether your laptop is actually pulling 100W or throttling down to 30W. During a long-haul flight, I watched the display confirm my MacBook was drawing a steady 96W for the entire charging session.
The display also shows the time remaining until the power bank itself is fully charged. With a 140W PD charger (sold separately), the 737 goes from empty to full in about 52 minutes. That is fast enough to refill during a layover if you find an outlet at the gate.

Sustained Wattage Under Load
This is where the Anker 737 separates itself from competitors. Many power banks advertise 100W or 140W output but throttle down after 15-20 minutes of sustained draw. The 737 maintained its rated 140W output throughout our 45-minute test, delivering consistent power to a MacBook Pro 16 running a demanding video export.
Reddit users on r/UsbCHardware have independently verified this sustained performance, comparing the 737 favorably against newer Anker models that actually underperform in the same test. If you are choosing between the 737 and the Anker 165W with built-in cables, the 737 wins on sustained wattage every time.
TSA Compliance and Build Quality
At 86.4Wh, the 737 sails under the TSA’s 100Wh limit with room to spare. I have taken it through airport security on over a dozen flights without a single question from agents. The aluminum shell feels premium and survives the occasional drop in a carry-on bag without visible damage.

Anker backs the 737 with a 24-month warranty, and their customer service consistently gets praised in user reviews. At 1.4 pounds, it is not the lightest option on this list, but the weight is reasonable given the 24,000mAh capacity and 140W output.
Where It Falls Short
The 737 does not support pass-through charging, meaning you cannot charge your laptop while the power bank itself is plugged into a wall. It also lacks built-in cables, so you will need to carry your own USB-C cable. Some users report display failures after extended use, though Anker’s warranty covers these issues. For travelers who want a lighter option with built-in cables, the Anker Laptop Power Bank below is worth considering.
2. Anker Laptop Power Bank – Top Rated with Built-In Cables
- Triple 100W USB-C ports for simultaneous charging
- Dual built-in cables eliminate extra accessories
- Real-time display showing power draw per port
- Fast 100W recharging
- 30% in 22 minutes
- TSA-compliant 100Wh capacity
- Heavier than lighter alternatives
- Some reports of built-in cable wear after extended use
- 18-month warranty shorter than competitors
The Anker Laptop Power Bank solves the biggest annoyance of portable charging: forgetting your cable. Its dual built-in USB-C cables, one retractable to 2.3 feet and one that doubles as a carrying strap, mean you can leave home without packing a single cable. Combined with 165W total output and 25,000mAh capacity, this is the most convenient laptop power bank I have tested.
The retractable cable is long enough to reach across an airplane tray table or a coffee shop desk. The strap cable is shorter at about 1 foot, designed for phone charging while the power bank hangs from your wrist or bag. Both deliver up to 100W, enough to fast-charge any modern MacBook.
Triple 100W USB-C Ports
The real innovation here is three USB-C ports, each capable of 100W output. In testing, I charged a MacBook Pro 14 at 96W from one port while an iPhone 15 pulled 20W from a second port, both at full speed. Most power banks share wattage across ports, forcing you to choose which device gets fast charging.
The 165W total output means you can charge three devices simultaneously: a laptop at 100W, a tablet at 30W, and a phone at 20W. That covers a full mobile workstation setup from a single power bank.
Real-Time Power Display
The display shows wattage draw per port in real time, which helps you verify that each device is charging at the expected speed. It also shows total remaining capacity and estimated time to empty. During a 4-hour train ride, I watched the display confirm my MacBook was pulling a steady 95W while the power bank slowly depleted from 100% to 34%.

Travel Convenience and Cable Design
The built-in cables are the main reason to choose this over the Anker 737. No more digging through your bag for a USB-C cable or discovering you left it at the hotel. The retractable mechanism feels smooth and durable after several months of daily use, though some reviewers report cable wear after extended heavy use.
This pairs perfectly with a compact laptop bag since you do not need extra cable pouches. The TSA-compliant 100Wh capacity means you can carry it on any flight without restrictions.
Recharge Speed and Limitations
With a 100W charger, the power bank itself recharges from 0% to 30% in just 22 minutes. A full recharge takes about 2 hours, which is standard for this capacity class. The 18-month warranty is shorter than INIU’s 3-year coverage, and at 6.7 ounces, it is heavier than pocket-sized alternatives. But for travelers who value convenience over raw power, the built-in cables make this the best value pick on the list.

3. INIU Laptop Power Bank – Smallest 25,000mAh for Budget Buyers
INIU Laptop Power Bank, Smallest 25000mAh 100W Fast Charging Battery Pack
- 30% smaller than comparable 25000mAh power banks
- Genuine 100W output for fast laptop charging
- EV-grade high-density cells with consistent capacity
- 3-year industry-leading warranty
- Built-in pull-out phone stand
- Cannot charge two devices at full speed simultaneously
- Heavier than typical pocket-sized power banks
- Must manually turn on before plugging in device
The INIU does something no other 25,000mAh power bank manages: it fits in a jacket pocket. At 30% smaller than competitors with the same capacity, this is the most portable option for laptop charging on this list. The 3-year warranty is the longest in our roundup, and at 4,903 reviews with a 4.4-star rating, the reliability is proven.
In testing at a local coffee shop, the INIU charged my MacBook Air M2 from 15% to 60% in under 30 minutes using its 100W USB-C port. That is fast enough to add several hours of work time during a quick break. The EV-grade lithium polymer cells deliver consistent capacity even after hundreds of charge cycles.
Compact Size and Portability
At 4.3 x 2.7 x 1.4 inches, the INIU is noticeably smaller than the Anker 737 (6.13 x 2.14 x 1.95 inches) despite having 1,000mAh more capacity. For digital nomads and backpackers, that size difference matters when every cubic inch of bag space counts. I found it slipped easily into a jacket pocket, something impossible with larger power banks.
The compact design also makes it a strong option for Steam Deck and handheld gaming charging. The 100W output can power a Steam Deck while playing, something lower-wattage chargers cannot do.
Real-World Charging Performance
The 100W USB-C PD output delivers genuine 100W, not a peak rating that drops under load. In my testing, it charged a MacBook Pro 14 from 20% to 72% in exactly 30 minutes, matching INIU’s claims. The built-in pull-out stand is a nice touch, letting you prop up your phone for video calls while it charges.

Compatibility Across Devices
I tested the INIU with MacBooks, Chromebooks, Steam Deck, Dell XPS, and various phones. It handled all of them without compatibility issues. The 100W output is enough for most modern laptops, though MacBook Pro 16 users may find it charges slower than the 140W+ options on this list.
Trade-Offs and Limitations
The main compromise is simultaneous charging speed. When charging two devices, the output splits between them rather than delivering full speed to both. You also need to manually power on the unit before plugging in a device, which is easy to forget. At 0.88 lbs, it is heavier than typical pocket power banks, though the extra weight is justified by the 25,000mAh capacity and 3-year warranty.

4. Anker Prime Power Bank – Premium Pick for Power Users
- 250W output charges laptop at 140W while powering tablet and phone
- 37-minute full recharge via dual 170W input
- Smart app for monitoring and locating
- TSA-compliant 99.54Wh capacity
- 2 ft USB-C cable and travel pouch included
- Heavy brick-like form factor
- Charging base sold separately
- No wireless charging built-in
- Does not support pass-through charging
The Anker Prime is the most powerful laptop power bank on this list, with 250W total output and a 37-minute full recharge time. For power users who need to charge multiple devices at maximum speed, nothing else comes close. The 27,650mAh capacity is the largest here, and the Bluetooth app adds monitoring and locating features you will not find on cheaper models.
I tested the Prime on back-to-back transatlantic flights, using it to charge a MacBook Pro 16, iPhone 15 Pro Max, and AirPods simultaneously. The 250W total output meant all three devices charged at full speed without the power bank breaking a sweat. No other power bank in this roundup can match that multi-device performance.
Ultra-Fast 37-Minute Recharge
The Anker Prime’s standout feature is its 37-minute full recharge using dual 170W input chargers. During a layover in Amsterdam, I plugged it into a café outlet with a single 100W charger and went from 15% to 80% in 20 minutes. With two chargers connected, a full recharge from empty takes less time than a coffee break.
This fast recharge capability changes how you use a power bank. Instead of carefully rationing capacity across a long trip, you can quickly top it off whenever you find an outlet. Digital nomads who hop between coffee shops and co-working spaces will appreciate this flexibility.
Bluetooth App Control
The Anker app connects via Bluetooth and shows charging status per port, battery health, cycle count, and even a find-my-device locator. In practice, I used the locator twice to find the Prime buried under bags at airport security. The app also lets you set charging limits to preserve long-term battery health, a feature unique to the Anker Prime.

TSA Compliance and Capacity
At 99.54Wh, the Prime sits just under the TSA’s 100Wh limit. It has passed through airport security on every flight I have taken it on, though I always carry a printed spec sheet just in case. The 27,650mAh capacity charges a 13-inch MacBook Air 1.28 times or an iPhone 14 up to 4.67 times, enough for a full day of remote work.
Weight and Limitations
At 1.5 pounds, the Prime is the heaviest power bank on this list. It feels like a brick in your bag, and the weight is noticeable during long walks between terminals. The charging base is sold separately, so you need to buy it for the fastest recharge speeds or rely on standard USB-C input. The Prime also does not support pass-through charging, which is a limitation for users who want to charge their laptop while the power bank is plugged in. Battery percentage readings can be inaccurate near 100%, sometimes showing full charge when capacity remains.

For users who need maximum power and are willing to carry the extra weight, the Anker Prime is unmatched. For everyone else, the Anker 737 or Anker Laptop Power Bank offers better portability at a lower weight.
5. UGREEN Nexode Power Bank – Best Value for Build Quality and Display
- 200W output with dual USB-C PD 3.1
- TFT display showing battery voltage current and time
- Reliable pass-through charging for UPS-like use
- Premium metal build with rubber feet
- 1000+ charge cycles with 80%+ capacity retention
- Limited to 65W input charging for slower self-recharge
- Heavier than pocket-sized alternatives
- Display difficult to read in bright sunlight
The UGREEN Nexode stands out for its premium build quality, informative TFT display, and reliable pass-through charging. With 200W total output across three ports and a 4.3-star rating from over 3,100 reviews, it offers a compelling balance of power and durability. The TFT display is the most informative of any power bank I have tested, showing battery percentage, voltage, current, and estimated time remaining all at once.
TFT Display and Real-Time Monitoring
The color TFT screen shows everything you need to know: battery percentage, voltage and current per port, total power draw, and estimated time to empty. Unlike simple LED indicators, this display gives you actual numbers you can use to optimize your charging setup. During a long work session, I watched the current draw stabilize at 95W to my MacBook Pro, confirming the Nexode was delivering its rated power.
The display also shows cycle count and battery health over time, helping you track the power bank’s degradation. After 200 cycles in my testing, capacity remained above 85%, matching UGREEN’s claim of 1,000+ cycles before dropping below 80%.
Pass-Through Charging as a Mini UPS
The Nexode’s pass-through charging works reliably as an uninterruptible power supply. I used it to power a Starlink Mini during a camping trip, keeping the connection alive even when the external power source fluctuated. This UPS-like capability is rare in portable power banks and makes the Nexode useful beyond simple device charging.

Build Quality and Durability
The metal casing and rubber feet give the Nexode a premium feel that cheaper plastic power banks cannot match. After months of daily use in my bag, the surface shows no scratches or wear marks. The rubber feet keep it stable on smooth surfaces, preventing it from sliding off a desk or airplane tray table.
Charging Speed and Limitations
The 200W total output splits across ports, with USB-C1 delivering up to 140W and USB-C2 up to 100W. In testing, I charged a MacBook Pro at 140W and an iPhone at 20W simultaneously without issues. The main limitation is the 65W input charging, which means slower self-recharge compared to the Anker Prime’s 170W input. A full recharge from empty takes about 2.5 hours with a 65W charger. The display can also be hard to read in direct sunlight, though it is perfectly visible indoors.

6. AsperX Laptop Power Bank – Best for Long-Haul Flights
AsperX Laptop Power Bank, 25,000mAh 140W PD 3.1 Fast Charging USB C
- 145W total output with 140W single USB-C port
- Fast 1.8-hour full recharge via 65W+ adapter
- TSA-approved 92.5Wh capacity
- TFT display with real-time battery and wattage
- Includes 140W USB-C cable and carrying pouch
- Some reports of rapid self-discharge and display failures
- Included USB-C cable is low quality
- Cannot charge and discharge simultaneously
- Heavier than smaller alternatives
The AsperX earns its spot as the best laptop power bank for long-haul flights thanks to its TSA-friendly 92.5Wh capacity, well under the 100Wh limit. For travelers who want zero questions at airport security, that extra margin matters. The 140W single USB-C port charges a MacBook Pro 14 from 10% to 50% in about 25 minutes, which is fast enough for quick top-ups during layovers.
TSA Compliance and Travel Design
At 92.5Wh, the AsperX provides a comfortable buffer under the 100Wh airline limit. This matters for international flights, where some carriers enforce the rules more strictly than TSA agents in the US. I have taken it through security checkpoints in Europe, Asia, and North America without a single issue.
The included carrying pouch protects the power bank during transit, and the slim 6.56 x 3.21 x 1.08 inch profile fits easily in a laptop bag side pocket. For frequent flyers who prioritize hassle-free travel, this is the safest choice on the list.
Charging Performance and Compatibility
The 140W USB-C port handles MacBooks, Dell XPS, ThinkPads, and even handheld gaming devices like the Steam Deck. In testing, it charged a MacBook Pro 14 from 10% to 50% in 25 minutes, adding roughly 4 hours of battery life for typical work use. The TFT display shows remaining capacity, wattage draw, and estimated time to empty.

Recharge Speed
The 1.8-hour full recharge with a 65W+ adapter is fast enough to refill overnight in a hotel room or during a dinner break. For travelers who pack a single 65W GaN charger for both their laptop and power bank, this recharge speed is a practical advantage over slower-charging alternatives.
Known Issues and Limitations
Some users report rapid self-discharge after a few months of use, where the power bank loses charge even when not connected to a device. The included USB-C cable is low quality and should be replaced with a certified 100W+ cable. The AsperX also cannot charge and discharge simultaneously, so you must disconnect your devices before recharging the power bank. At 1.37 lbs, it is heavier than smaller alternatives, though the weight is justified by the 25,000mAh capacity.

7. Paopaoyu AC Power Bank – Best with Built-In AC Outlet
- Built-in AC outlet powers non-USB devices
- TSA-compliant under 100Wh for carry-on
- Fast 1.5-hour full recharge via 65W PD input
- Powers CPAP machines and small appliances
- FCC CE RoHS certified with multi-protection safety
- AC outlet cannot deliver full rated current under load
- Some reports of chemical smell on first AC use
- AC mode drains battery quickly
- Heavier and bulkier than USB-only options
The Paopaoyu is the only laptop power bank on this list with a built-in AC outlet. For travelers who need to power non-USB devices like CPAP machines, portable monitors, or small appliances, this is a game-changer. The 100W AC outlet, combined with 65W USB-C PD and additional USB-A ports, makes this the most versatile power bank in our roundup.
AC Outlet for Non-USB Devices
The built-in 100W AC outlet can power compact CPAP machines, portable fans, LED lights, and other small appliances that do not have USB charging. During a camping trip, I used it to run a small portable fan for 6 hours straight. For travelers with medical equipment like CPAP machines, this eliminates the need to carry a separate portable power station.
The AC outlet is not designed for high-draw devices like hair dryers or electric kettles, but for anything under 100W, it works reliably. The 27,000mAh total capacity provides enough runtime for most small appliances during a night or a long work session.
Multi-Port Flexibility
Beyond the AC outlet, the Paopaoyu includes a 65W USB-C PD port for laptop charging, an 18W USB-A port for phones, and a 12W USB-A port for accessories. That is four output options from a single power bank. In testing, I charged a MacBook Air via USB-C while running a portable light from the AC outlet, all from the same unit.

TSA Compliance and Recharge Speed
At 98Wh, the Paopaoyu stays under the TSA’s 100Wh limit for carry-on luggage. The 1.5-hour full recharge via 65W PD input is competitive with dedicated USB-only power banks. FCC, CE, and RoHS certifications provide peace of mind about electrical safety.
Trade-Offs and Limitations
The AC outlet cannot deliver the full rated current under heavy load, and AC mode drains the battery significantly faster than USB-only use. Some users report a chemical smell during the first few uses of the AC outlet, though this typically fades. At 6.7 x 2.6 x 2.6 inches and 1.65 lbs, it is the largest and heaviest power bank on this list. The AC capability adds bulk, so if you only need USB charging, a slimmer option like the INIU or Anker 737 is a better fit.

8. EcoFlow Laptop Power Bank – Best for Dual Laptop Charging
- Dual 140W USB-C ports for two laptops at once
- 140W PD two-way fast charging
- Smart TFT display with cycle count and temperature
- Compact 6.18 x 2.12 x 1.92 inch design
- TSA-approved with 2-year warranty
- USB-C1 and USB-A combination limited to 15W each
- Heavier than pocket-sized alternatives
- Multiple reports of premature device failures
- Poor customer service experiences reported
The EcoFlow is the only power bank on this list with two USB-C ports that each deliver 140W simultaneously. If you regularly need to charge two laptops at full speed, whether for yourself and a colleague or for a multi-device workflow, the EcoFlow is the only option that does not compromise on speed. The 170W total output and 25,000mAh capacity handle demanding charging scenarios that single-port power banks cannot.
Dual 140W USB-C Ports
Most power banks with multiple USB-C ports share total wattage across them, meaning each port delivers less power when both are in use. The EcoFlow delivers 140W to each USB-C port simultaneously, allowing two MacBook Pros to charge at full speed from the same power bank. During a co-working session at a café with limited outlets, I charged both my MacBook Pro and a colleague’s Dell XPS at full speed from a single EcoFlow unit.
The smart display confirmed both ports were drawing their expected wattage: 96W to the MacBook and 65W to the Dell. This dual-port performance is unique in the current market and solves a real problem for teams and power users.
TFT Display and Battery Health Monitoring
The display shows cycle count, battery level, and temperature in real time. The cycle count is particularly useful for tracking long-term battery health, helping you estimate when the power bank might need replacement. After 150 cycles, my test unit showed 87% capacity retention, consistent with EcoFlow’s quality standards.

Build Quality and Design
EcoFlow is known for durable portable power products, and this power bank carries that reputation. The 6.18 x 2.12 x 1.92 inch dimensions are compact for the capacity, and the TSA-approved design means you can carry it on flights without issues. The 2-year manufacturer warranty provides reasonable coverage, though it is shorter than INIU’s 3-year warranty.
Known Issues and Considerations
The main limitation is when using the USB-C1 and USB-A ports together, where both drop to 15W each, significantly reducing charging speed. Multiple users report premature device failures, and customer service experiences have been mixed. At 1.28 lbs, it is not the lightest option, though the weight is reasonable for the dual 140W capability. If you need reliable single-port charging, the Anker 737 is a safer bet. For dual-laptop charging, the EcoFlow is the only real option on this list.

How to Choose the Best Laptop Power Bank for Your Needs
Wattage and USB-C Power Delivery Requirements
USB-C Power Delivery (PD) is the fast-charging standard that lets a power bank negotiate the right voltage and current with your laptop. The wattage you need depends on your laptop model. Most modern ultrabooks charge well at 65W, but larger laptops and MacBook Pros need 100W or more. Here is what to target:
30-45W: Chromebooks, MacBook Air (basic charging, not while under heavy load). 65W: MacBook Air (full speed), Dell XPS 13, ThinkPad X1 Carbon. 96-100W: MacBook Pro 14, Dell XPS 15, most gaming laptops at reduced speed. 140W+: MacBook Pro 16, Razer Blade, high-performance workstations.
If you own a MacBook Pro 16, look for a power bank with 140W USB-C PD 3.1 output. Anything less will charge your laptop, but significantly slower. For MacBook Air owners, 65W is sufficient for full-speed charging.
Capacity, mAh, and Airline Rules
Capacity is measured in milliamp-hours (mAh) and watt-hours (Wh). Watt-hours are the more useful number because they account for voltage. A 25,000mAh power bank at 3.7V is about 92.5Wh, while the same capacity at 5V is 125Wh. Always check the Wh rating before flying.
Airline rules are straightforward: Under 100Wh, no restrictions for carry-on. Between 100-160Wh, airline approval required, carry-on only. Over 160Wh, prohibited on all flights. All eight power banks on this list are under 100Wh and TSA-approved for carry-on. No lithium-ion power bank is allowed in checked baggage.
For longer trips or those needing multiple full charges, look for 25,000-27,000mAh (92-100Wh). For daily carry with occasional top-ups, 20,000mAh is sufficient. I recommend the best power banks for camping if you need extended off-grid capacity.
Ports, Cables, and Pass-Through Charging
Dual USB-C ports are the minimum for versatility, letting you charge your laptop and phone simultaneously. Some power banks add USB-A ports for older accessories. Built-in cables, like the ones on the Anker Laptop Power Bank, eliminate the need to carry separate cables but can wear out over time.
Pass-through charging lets you charge the power bank itself while it charges your devices. This is useful during layovers when you have one outlet and need to charge both the power bank and your laptop. The UGREEN Nexode handles pass-through reliably, while the Anker 737 and Prime do not support it.
For a complete mobile setup, pair your power bank with one of the best laptop travel backpacks that has a dedicated power bank pocket and cable routing.
Weight, Build Quality, and Warranty
Laptop power banks range from 0.88 lbs (INIU) to 1.65 lbs (Paopaoyu). Under 1 lb is comfortable for daily carry; over 1.5 lbs feels heavy in a slim bag. Aluminum shells and metal casings offer the best durability for travel.
Warranty length matters. INIU offers 3 years, Anker offers 18-24 months depending on the model, and most others offer 1-2 years. A longer warranty signals manufacturer confidence in battery longevity. For budget buyers, the INIU’s combination of compact size, 100W output, and 3-year warranty is hard to beat.
