If you’re trying to keep a modern laptop charged away from a wall outlet, you’ve run into the same problem I have: most power banks just don’t push enough juice. The best Laptop Power Bank for PD 3.1 delivers a full 140W output, which means you can actually fast-charge a MacBook Pro or Dell XPS while also topping off your phone. I’ve spent weeks testing seven models to find which ones actually deliver on that promise.
Every power bank on this list meets three hard requirements: it supports the PD 3.1 protocol at 140W or higher, it has at least 20,000mAh capacity for real laptop charging, and it includes a digital display so you’re not guessing how much power is left. I focused on models from brands with solid customer ratings and real-world availability, skipping anything that looked too good to be true on paper.

How I Selected These Products
I only considered power banks that actually support PD 3.1 at 140W output, since that’s the real standard for fast laptop charging. Every model also needed at least 20,000mAh capacity so you can get a meaningful charge on a drained MacBook or Dell XPS.
Value mattered a lot in my ranking. I compared real-world charging speeds and portability alongside price, looking for the best balance of performance and cost. A cheap power bank that doesn’t deliver isn’t a bargain at all.
User feedback from verified buyers helped separate the hype from the truth. I cross-checked star ratings and comment patterns, focusing on reliability and long-term durability rather than just launch-day excitement. Models with consistent complaints got knocked down.

The Anker 737 is the most popular laptop power bank on Amazon for a reason, and after testing it I can see why. It pushes a full 140W through its USB-C port, which is enough to fast-charge a MacBook Pro while still having two other ports for your phone and tablet. The smart display shows exact remaining time and wattage, so you always know what’s happening.
This is the best Laptop Power Bank for PD 3.1 for most people because it balances proven reliability with real-world performance. My only complaint is that at 24,000mAh, it’s slightly heavier than some competitors, so it’s not the most pocket-friendly option for ultralight travel.
✅ Pros
- Proven track record with over 16,000 ratings and 2,000+ bought monthly
- Smart display shows real-time wattage and charge estimates
- 140W single-port output charges a MacBook Pro to 50% in about 30 minutes
- Works with iPhone 16, Vision Pro, Samsung, and most USB-C laptops
❌ Cons
- Heavier than some 25,000mAh competitors at similar capacity
- Only 24,000mAh capacity lags behind newer 27,600mAh models

The Ansody 140W Power Bank delivers PD 3.1 fast charging at a price that undercuts almost every other 25,000mAh option on the market. I was surprised by how well it handled charging my Dell XPS 13 alongside an iPhone — the smart digital display kept me informed without any guesswork.
This is the best Laptop Power Bank for PD 3.1 if you’re on a tight budget but still need full 140W laptop charging. The catch is that it’s a newer brand with only 125 ratings, so you’re trading long-term track record for the lower price.

- PD 3.1 at 140W matches premium chargers for a fraction of the cost
- Smart digital display is clear and easy to read

If you love seeing detailed power stats at a glance, this is the best Laptop Power Bank for PD 3.1 for you. The limitation is that the TFT display is a bit power-hungry, so you lose a small amount of battery life to the screen itself.

This is the best Laptop Power Bank for PD 3.1 if portability is your top priority and you don’t need to charge a laptop more than once. The trade-off is the smaller 20,000mAh capacity, which means you’ll get fewer full laptop charges compared to the 25,000mAh+ options.

What to Look for in Laptop Power Bank for PD 3.1
Picking the wrong power bank for your laptop is frustrating — you end up with slow charging or a dead battery in the middle of your workday. I’ve tested enough of these to know that most people focus on the wrong specs and end up overpaying for features they don’t need. Here’s what actually matters when you’re shopping for the best Laptop Power Bank for PD 3.1.
Power Output (Wattage)
The wattage determines how fast your laptop actually charges. For PD 3.1, you want a minimum of 140W from a single USB-C port — that’s the sweet spot for modern MacBook Pros and Dell XPS models. Anything less than 100W will charge your laptop slowly or might not charge it at all while you’re using it. My rule of thumb is simple: match or exceed your laptop charger’s wattage. If your laptop came with a 140W brick, don’t settle for a 100W power bank.
Battery Capacity (mAh and Wh)
Capacity is measured in milliampere-hours (mAh) and watt-hours (Wh), and both numbers matter. For laptop charging, look for at least 20,000mAh — that gives you roughly one full charge for a 13-inch MacBook Pro. The Wh rating is crucial for air travel since the FAA caps carry-on batteries at 100Wh. Most quality power banks in this category sit between 86Wh and 99.36Wh, which keeps them flight-legal while maximizing capacity.
PD 3.1 Protocol Support
Not all USB-C power banks support PD 3.1, and that’s the protocol that enables 140W charging. Older PD 3.0 tops out at 100W, which means slower charging for newer laptops. Make sure the product explicitly states “PD 3.1” in its specs — if it only says “PD” or “USB-C fast charging,” it might be the older standard. This is the single most common mistake I see buyers make.
Port Configuration
Consider how many devices you’ll charge at once. A good laptop power bank should have at least two USB-C ports and one USB-A port so you can charge your laptop, phone, and earbuds simultaneously. Pay attention to the total output rating — some banks advertise 140W but that’s only available from one port, while the other ports drop to much lower speeds. If you travel with multiple devices, look for a bank with a high total output like 162.5W or 170W.
Display and Build Quality
A digital display isn’t just a gimmick — it’s genuinely useful for knowing how much charge you have left and whether your devices are pulling the right wattage. Basic LED indicators are frustratingly vague. For build quality, aluminum unibody construction is more durable and dissipates heat better than plastic, but it adds weight and cost. Decide which trade-off matters more for your daily carry.
Flight Approval and Size
If you travel by plane, check the Wh rating before buying anything over 20,000mAh. The FAA limit is 100Wh, and most premium laptop power banks are designed to sit just under that threshold. Also consider physical size — a 27,600mAh bank will be noticeably thicker and heavier than a 20,000mAh one. I always recommend checking the dimensions against your laptop bag’s pocket before committing.
My Shortcut Advice: Prioritize a single 140W PD 3.1 USB-C port and at least 24,000mAh capacity — everything else is a bonus. Don’t overpay for features like huge displays or ultra-high total output if you only charge one laptop at a time.
Frequently Asked Questions
What is the best Laptop Power Bank for PD 3.1 overall?
In my testing, the Anker 737 Power Bank is the best overall pick. It delivers a full 140W PD 3.1 output from a trusted brand with over 16,000 ratings, and the smart display shows you exactly how much power you’re pulling. It’s not the cheapest option, but it’s the most reliable one I’ve tested for consistent laptop charging.
How many watts do I need to charge a MacBook Pro with PD 3.1?
You need at least 140W from a single USB-C port to fast-charge a modern 16-inch MacBook Pro at full speed. A 100W PD 3.0 power bank will still charge it, but much slower — especially if you’re using the laptop while it’s plugged in. Every power bank on this list delivers 140W, so you’re covered with any of them.
Is a PD 3.1 power bank worth it over a regular PD 3.0 model?
Yes, if you own a newer laptop that supports 140W charging. PD 3.1 delivers that extra 40W over PD 3.0’s 100W limit, which cuts charging time for a MacBook Pro by roughly 30 to 40 minutes. If your laptop only supports 100W max, you won’t see a difference, and a good PD 3.0 bank will save you money.
Can a Laptop Power Bank for PD 3.1 charge a phone and laptop at the same time?
Absolutely, but you need to check the total output rating. The HARGEEK 170 Power Bank pushes 170W total, so it can handle a MacBook at 140W and an iPhone simultaneously without slowing down. Most 140W banks split the power when you use multiple ports, so your laptop might drop to 100W if you plug in a second device.
How long will a 25,000mAh power bank charge a Dell XPS 13?
A 25,000mAh power bank like the Ansody 140W or the INIU 25000mAh will fully charge a Dell XPS 13 about one and a half times. The XPS 13 has roughly a 52Wh battery, and these banks hold around 92.5Wh of usable energy. You’ll get a full charge plus a partial top-up on the second round.
What’s the difference between the two AsperX Laptop Power Banks on this list?
The main difference is build material and capacity. The first AsperX model (25,000mAh) uses a plastic body with a TFT display, while the second one (27,600mAh) has an aluminum unibody construction that feels much more premium. The aluminum version also offers 162.5W total output versus 140W, but it costs more and is slightly heavier.
Can a PD 3.1 power bank charge a Steam Deck or Nintendo Switch?
Yes, and it’s actually overkill in a good way. The Steam Deck pulls around 45W max, and the Switch pulls about 18W, so any 140W bank will charge them incredibly fast. The Ansody 140W and AsperX models both list Steam Deck compatibility, and I’ve tested the CUKTECH 15 Ultra with a Steam Deck — it works perfectly.
Are these power banks allowed on airplanes?
Most of them are, but you need to check the Wh rating. The FAA limit is 100Wh for carry-on bags, and every power bank on this list is under that threshold. The AsperX 27,600mAh model sits right at 99.36Wh, which is the legal maximum. You cannot put any of these in checked luggage — they must go in your carry-on.
My Final Verdict
After testing all seven power banks, the Anker 737 is the clear winner for most people. It delivers consistent 140W PD 3.1 output, has over 16,000 positive ratings backing its reliability, and the smart display gives you real-time charging data. The Ansody 140W is my runner-up for budget-conscious buyers, and the AsperX with the TFT display is the best choice if you want the most informative screen on the market.
If you need a proven, no-surprises power bank that will charge your laptop fast for years, grab the Anker 737. If budget is the priority and you’re okay with a newer brand, the Ansody 140W is an excellent value at 25,000mAh. Still unsure? Go with the Anker — it’s the safest bet on this list.
