You know the drill: you’re deep into work at a coffee shop, your laptop is at 15%, and the only outlet is behind a bookshelf. A laptop power bank with pass-through charging fixes this — it keeps your laptop topped up and the battery pack itself recharged at the same time. That’s the key feature I looked for when testing these nine models.
I picked these specific power banks because they all deliver at least 140W total output, support pass-through charging (charge the bank and your laptop simultaneously), and are small enough to actually throw in a bag. I also prioritized models with smart displays so you’re never guessing how much juice is left. Every single one here earned its spot through real-world testing, not just spec sheets.

How I Selected These Products
I started by filtering for models that actually support pass-through charging — that’s the whole point of this list. Every power bank here delivers at least 140W total output and has a smart display so you can see your charge status at a glance. Capacity had to be 20,000mAh or higher to be worth your money.
Price matters, but I ranked based on what you get for it. A power bank that costs less but lacks a display or has slow recharging speeds isn’t a bargain — it’s a headache. I weighed build quality, portability, and how well each one handled real-world use with a MacBook Pro and an iPhone plugged in.
I also dug into user reviews and star ratings. Products with hundreds or thousands of ratings got more weight than brand-new releases with only a handful. If a model had consistent complaints about overheating or failing after a few months, it didn’t make the cut. Reliability is non-negotiable here.
Top Pick
Anker 737 Power Bank
140W Max Output | 24,000mAh | Smart Display | 3 Ports | Pass-Through Charging
- Power Through Your Day: With a 24,000mAh capacity, this laptop power bank...
- Intelligent Charge Monitoring: The smart digital display on this laptop...
- Rapid Two-Way Charging: Experience fast power delivery with 140W charging...
I’ve tested a lot of laptop power banks, and the Anker 737 is still the one I reach for most. The 140W max output means it can charge my MacBook Pro at full speed while still juicing up my iPhone on the second port. The smart display is genuinely useful — it shows remaining capacity in watt-hours and estimated charge time, so I never have to guess.
This is best for anyone who wants a proven, reliable power bank that just works. The only catch is the 24,000mAh capacity — it’s enough for one full laptop charge plus some phone top-ups, but if you need to charge a MacBook Pro twice in a row, you’ll want something bigger. Over 2,000 people bought this in the past month, and with 16,931 ratings sitting at 4.4 stars, it’s clearly doing something right.
✅ Pros
- 140W single-port output charges most laptops at full speed
- Smart display shows remaining capacity and estimated charge time
- 3 ports let you charge a laptop, phone, and earbuds simultaneously
- Over 16,900 ratings with a 4.4-star average — proven reliability
❌ Cons
- 24,000mAh capacity is good but not huge for heavy laptop users
- No built-in cables — you’ll need to bring your own USB-C cord

- Triple 100W USB-C Ports for Multi-Device Charging: Ideal for laptop users,...
- 25,000mAh for Long-Haul Power: Tackle week-long trips or extended camping...
- Dual Built-In Cables for Travel: Features two USB-C cables, one extendable...
This Anker Laptop Power Bank is the one I grab when I’m traveling and don’t want to dig through my bag for cables. The built-in retractable cables are a legit big improvement — they’re sturdy, retract smoothly, and save me from the dreaded “where’s my USB-C cord” panic. With 25,000mAh capacity and three 100W USB-C ports, I can charge my MacBook, iPhone, and iPad all at once.
This is the best pick for frequent travelers who hate carrying extra cables. It’s flight-approved, so you can toss it in your carry-on without worry. The trade-off is that the retractable cables are fixed length — about 2 feet — so if you need a longer reach, you’ll still want to pack a separate cable. Over 10,000 people bought this in the past month, and with an 4.5-star average across 8,931 ratings, it’s clearly a crowd favorite.
✅ Pros
- Built-in retractable cables mean no fumbling for cords
- Triple 100W USB-C ports charge three devices at full speed
- 25,000mAh capacity gives you a full laptop charge plus extras
- Flight-approved for worry-free air travel
❌ Cons
- Retractable cables are short — about 2 feet — limiting reach
- No USB-A port, so older devices need an adapter

The Ansody 140W Power Bank surprised me for the price. It packs 25,000mAh capacity and PD3.1 fast charging into a package that costs less than most competitors. The smart digital display is clear and shows exact remaining percentage, which I appreciate when I’m trying to decide if I need to top off before heading out.
This is best for budget-conscious buyers who still want solid performance and a laptop-sized battery. The catch is that it’s a newer product with only 125 ratings, so it doesn’t have the long-term track record of the Anker options. I also found the build feels slightly less premium than the more expensive picks — the plastic casing is functional but not fancy.
✅ Pros
- 25,000mAh capacity at a budget-friendly price point
- PD3.1 fast charging supports modern laptops at full speed
- Smart digital display shows exact battery percentage clearly
- Compatible with MacBook, Dell XPS, iPad, Steam Deck, and more
❌ Cons
- Only 125 ratings so far — less proven than established brands
- Plastic build feels less durable than aluminum alternatives

The AOHI 140W Power Bank is an absolute beast with its 40,000mAh capacity — that’s enough to charge a MacBook Pro nearly twice over. It supports PD3.1 fast charging at 140W, so even power-hungry laptops get topped up quickly. The “Future Starship” design is a bit flashy for my taste, but the 2-in-1 form factor means it doubles as a camping power station.
This is best for people who need maximum capacity for long trips or off-grid work sessions. The downside is size and weight — it’s noticeably bigger and heavier than the 25,000mAh options on this list, so it’s not ideal for daily carry. Also, with only 93 ratings at 3.9 stars, it’s less reviewed than I’d like for something this expensive.
✅ Pros
- Massive 40,000mAh capacity charges a laptop twice over
- 140W PD3.1 output supports the fastest laptop charging speeds
- 2-in-1 design works as both a power bank and camping station
- Compatible with MacBook Pro/Air, iPad Pro, iPhone 16, and Steam Deck
❌ Cons
- Large and heavy — not great for everyday carry in a backpack
- Only 93 ratings so far, and 3.9 stars is lower than most competitors

- Charge 3 Devices at Once. With a total 170W output and multi-port design,...
The EF ECOFLOW Laptop Power Bank stands out because it delivers 170W total output — the highest of any power bank in this price range. That means you can plug in two laptops simultaneously and still get fast charging speeds on both. The smart display is crisp and shows input/output wattage in real time, which I love for monitoring how fast my devices are actually charging.
This is best for power users who need to charge multiple high-wattage devices at once. The limitation is that it’s a newer model with only 103 ratings, so long-term reliability is still unproven compared to Anker’s established lineup. Also, the 25,000mAh capacity means you’ll get one full laptop charge, but not much extra for a second device.
✅ Pros
- 170W total output — highest in this price range for multi-device charging
- Dual 140W USB-C ports let two laptops charge at full speed
- Smart display shows real-time input and output wattage
- Flight-approved for easy travel and 25,000mAh capacity
❌ Cons
- Newer model with only 103 ratings — less established track record
- 25,000mAh gives one full laptop charge, not much extra for a second device

- [25,000mAh Capacity - Flight-Approved]: This 25,000mAh power bank features...
The AsperX Laptop Power Bank is a solid mid-range option that punches above its price. It delivers 140W PD 3.1 fast charging from a 25,000mAh pack, and the TFT smart display is one of the clearest I’ve seen at this price — it shows exact wattage going in and out. With 92.5Wh capacity, it’s flight-approved, so I can toss it in my carry-on without a second thought.
This is best for anyone who wants an Amazon’s Choice pick with a proven track record — 198 ratings at 4.3 stars and over 300 bought in the past month. The honest limitation is that the 140W output is shared across ports, so if you plug in two devices, the wattage splits and each charges slower. It’s fine for a laptop and phone, but don’t expect full speed on two laptops at once.
✅ Pros
- TFT smart display shows real-time wattage clearly
- 25,000mAh capacity with 140W PD 3.1 fast charging
- Flight-approved at 92.5Wh for worry-free travel
- Amazon’s Choice with 4.3 stars from 198 ratings
❌ Cons
- 140W output is shared across ports — slower with multiple devices
- No built-in cables, so you need to carry your own
Premium Build

- 𝑨𝒍𝒖𝒎𝒊𝒏𝒖𝒎 𝑼𝒏𝒊𝒃𝒐𝒅𝒚: AsperX...
This second AsperX model cranks things up with a 27,600mAh capacity and 162.5W total output — enough to charge my MacBook Pro faster than the 140W models. The aluminum unibody construction is a huge step up in feel and durability; it doesn’t flex or creak like plastic alternatives. At 99.36Wh, it’s right at the FAA limit for carry-on, so it’s flight-approved but maxing out the legal capacity.
This is best for anyone who wants a premium-feeling power bank with maximum legal flight capacity. The catch is that 27,600mAh is only marginally more than the 25,000mAh options — you’re paying more for the aluminum build and the extra 2,600mAh, not a huge capacity jump. Also, with 121 ratings, it’s less reviewed than the other AsperX model.
✅ Pros
- Aluminum unibody feels premium and resists damage
- 162.5W total output charges laptops faster than 140W models
- 27,600mAh capacity with PD3.1 for modern laptops
- Flight-approved at 99.36Wh — max legal carry-on capacity
❌ Cons
- Only 2,600mAh more than 25K models — marginal upgrade for the price
- Only 121 ratings — less proven than the other AsperX option

The CUKTECH 15 Ultra is the smallest power bank on this list at 20,000mAh, but don’t let the size fool you — it still pumps out 140W for fast laptop charging. The smart display is clean and easy to read, and the compact form factor makes it the most pocket-friendly option here. It’s flight-approved, which is expected at this capacity.
This is best for travelers who prioritize size and weight above all else. The trade-off is obvious: 20,000mAh means you’ll get about 80% of a full MacBook Pro charge, not a full one. If you need to top off your laptop once and also charge a phone, you’ll be cutting it close. Still, with a 4.7-star average from 444 ratings, it’s the highest-rated product on this list.
✅ Pros
- Compact 20,000mAh design — most portable option on this list
- 140W output still fast enough for any modern laptop
- 4.7 stars from 444 ratings — highest-rated product here
- Smart display and flight-approved for easy travel
❌ Cons
- 20,000mAh won’t fully charge a large laptop like a MacBook Pro 16
- Limited capacity means less room for charging multiple devices

The HARGEEK 170 Power Bank from the sharge store is a sleek option that delivers 170W total output from its 24,000mAh pack. The smart display is crisp and shows remaining capacity in both percentage and watt-hours, which I find handy for planning my charging sessions. It supports PD3.1 at 140W, so even power-hungry laptops like the MacBook Pro 16 charge at full speed.
This is best for users who want a stylish, high-output power bank with a smart display. The limitation is the 86.4Wh capacity — it’s below the FAA’s 100Wh limit, so it’s flight-approved, but it’s also less capacity than the 24,000mAh suggests because of voltage differences. With 403 ratings at 4.1 stars, it’s got a decent track record, but it’s not as popular as the top picks.
✅ Pros
- 170W total output — one of the highest on this list
- Smart display shows both percentage and watt-hours clearly
- PD3.1 at 140W supports the fastest laptop charging speeds
- Sleek design from the sharge store with 403 ratings
❌ Cons
- 86.4Wh capacity is lower than some 24,000mAh competitors
- 4.1-star rating is solid but not as high as the top picks
What to Look for in Laptop Power Bank with pass-through charging
I’ve tested enough power banks to know that buying the wrong one usually comes down to ignoring two things: pass-through support and actual wattage delivery. Most people grab the cheapest high-capacity option and then wonder why their laptop drains faster than it charges. Let me save you that headache.
Pass-Through Charging Support
This is the whole point of this list, so don’t skip it. Pass-through charging means you can plug the power bank into a wall outlet while it’s also charging your laptop — the bank acts like a passthrough for power. Without this feature, you have to choose: charge the bank or charge your laptop, but never both at the same time. Check the specs carefully because not every bank labeled “pass-through” handles it gracefully — some get hot or slow down significantly.
Power Output (Wattage)
Wattage determines how fast your laptop actually charges. Most modern laptops need at least 60W for a decent charge speed, and anything under 45W might not charge at all while you’re using the laptop. I recommend at least 100W per USB-C port for a reliable laptop power bank with pass-through charging. The 140W and 170W models on this list can handle even the most power-hungry MacBook Pro 16-inch at full speed.
Battery Capacity (mAh and Wh)
Capacity is measured in both milliamp-hours (mAh) and watt-hours (Wh). For laptops, pay more attention to Wh because it accounts for voltage differences. A 24,000mAh bank at 3.7V is about 88.8Wh, which gives roughly one full charge for a MacBook Pro. If you need two full charges, look for 40,000mAh options. Also remember that the FAA limits carry-on batteries to 100Wh — anything over that requires airline approval.
Number and Type of Ports
More ports aren’t always better if they share power. Some banks split their total wattage across all ports, so plugging in two devices cuts each one’s speed in half. I look for banks with at least two USB-C ports that can each deliver 100W independently. A third port is nice for charging earbuds or a phone, but don’t sacrifice per-port wattage for extra ports you won’t use.
Smart Display Features
A smart display isn’t just a gimmick — it’s genuinely useful for a laptop power bank with pass-through charging. The best displays show remaining capacity in percentage and watt-hours, plus real-time input and output wattage. This lets you see exactly how fast your laptop is charging and whether the bank itself is recharging at full speed. Without a display, you’re guessing when the bank will die.
Build Quality and Portability
Laptop power banks aren’t small, but some are noticeably easier to carry than others. Aluminum unibody models feel more durable and dissipate heat better than plastic ones, but they’re heavier. Look for flight-approved ratings if you travel — most banks between 20,000mAh and 27,600mAh fit within limits. I’d rather carry a slightly heavier bank that won’t crack in my bag than save a few ounces on something flimsy.
My Shortcut Advice: If you only remember one thing, make it this: buy a power bank that explicitly supports pass-through charging at the same wattage it delivers to your laptop — otherwise you’re paying for features you can’t actually use on the go.
Frequently Asked Questions
What is the best laptop power bank with pass-through charging overall?
I’d go with the Anker 737 Power Bank. It delivers 140W max output from a 24,000mAh pack, has a smart display that shows exact remaining capacity, and supports pass-through charging without overheating. With over 16,900 ratings at 4.4 stars, it’s the most proven option on the market right now.
How many watts do I need to charge a laptop while using it?
Most modern laptops need at least 60W to charge while you’re actively using them. If you’re pushing a MacBook Pro 16-inch or a gaming laptop, aim for 100W or more. Every power bank on this list delivers at least 140W total output, so any of them can handle a laptop under load — just check the per-port wattage to make sure one port can deliver enough.
Can I charge the power bank and my laptop at the same time?
Yes, that’s exactly what pass-through charging does. Plug the power bank into a wall outlet, then plug your laptop into the bank — both charge simultaneously. The Anker Laptop Power Bank and the EF ECOFLOW model both handle this well. Just make sure the power bank’s input wattage is high enough; a slow wall charger defeats the purpose.
How long will a 25,000mAh power bank run my laptop?
A 25,000mAh bank like the Ansody 140W Power Bank or the AsperX Laptop Power Bank gives roughly one full charge for a MacBook Pro 14-inch. For a smaller laptop like a MacBook Air, you’ll get closer to 1.5 charges. If you need two full charges for a large laptop, consider the AOHI 140W PD3.1 with its 40,000mAh capacity.
What’s the difference between PD 3.0 and PD 3.1?
PD 3.1 supports higher wattage — up to 240W — while PD 3.0 maxes out at 100W. For most laptops, PD 3.0 at 100W is plenty fast. But if you have a MacBook Pro 16-inch or a high-end Dell XPS, PD 3.1 lets you charge at 140W or more. The Anker 737 and the EF ECOFLOW both support PD 3.1 for the fastest possible charging.
Is a laptop power bank worth it if I already have a phone power bank?
It depends on your laptop’s battery life. Phone power banks usually top out at 20W output and 10,000mAh — nowhere near enough to charge a laptop. A dedicated laptop power bank with pass-through charging like the Anker Laptop Power Bank delivers 100W per port and 25,000mAh. If you ever work away from an outlet for more than a few hours, it’s absolutely worth it.
Are these power banks allowed on airplanes?
Most of them are, yes. The FAA allows batteries up to 100Wh in carry-on luggage without special approval. The AsperX Laptop Power Bank at 27,600mAh is rated at 99.36Wh, right at that limit. The CUKTECH 15 Ultra at 20,000mAh is well under. Just check the Wh rating on any bank before you fly — anything over 100Wh requires airline permission.
Can I use a laptop power bank to charge my phone and laptop at the same time?
Absolutely, as long as the power bank has enough ports and total wattage. The EF ECOFLOW Laptop Power Bank has dual 140W USB-C ports, so you can charge a laptop at full speed and still have 30W left for a phone. The key is checking whether the bank splits its total output across ports — some do, which slows everything down.
My Final Verdict
After testing all nine models, the Anker 737 Power Bank is my clear winner. It delivers 140W output, has a genuinely useful smart display, and its 24,000mAh capacity hits the sweet spot between portability and power. With over 16,900 ratings at 4.4 stars, it’s the most trusted option here. The Anker Laptop Power Bank is the runner-up for travelers who hate carrying cables, and the Ansody 140W Power Bank is the budget pick that still delivers 25,000mAh and PD3.1 charging at a fraction of the cost.
If you’re still on the fence, here’s the simple version: buy the Anker 737 if you want the best all-around performance and reliability. If you travel frequently and hate forgetting cables, grab the Anker Laptop Power Bank with built-in retractable cords. And if you’re on a tight budget but refuse to compromise on capacity, the Ansody 140W Power Bank gets the job done without breaking the bank.
