I’ve spent serious time testing two of Anker’s top portable laptop chargers: the Anker 737 Power Bank with its 24,000mAh capacity and 140W output, and the newer Anker 25,000mAh Power Bank that pumps out 165W with built-in retractable cables. Both promise to keep your MacBook, iPhone, or Samsung powered up, but they take very different approaches to get the job done.
This comparison is for anyone who needs a reliable power bank for charging a laptop and multiple devices while traveling or working remotely. The main trade-off here is raw single-device charging speed versus all-around convenience with built-in cables. Stick with me, and I’ll break down exactly which one fits your bag better.

Individual Product Breakdown
I put both of these Anker power banks through real-world laptop charging tests, checking speed, port versatility, and how easy they are to toss in a bag for travel.
Anker 737 Power Bank (PowerCore 24K)
24,000mAh | 140W Max | 3 Ports | 6.1 x 2.1 x 1.9 in | 22 oz
- 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...
This is the one I grab when I need to charge a MacBook fast. The 140W Power Delivery 3.1 is legit — it’ll juice up a laptop quicker than most competitors. I love the smart digital display that shows exact output and input wattage, plus estimated recharge time. At 24,000mAh, it charged my iPhone 16 Pro over four times in my tests. The only catch is you need a 5A cable and a 140W charger to get that full speed, and it’s a bit heavier than the newer model at 22 ounces.
✅ Pros
- 140W single-port output for ultra-fast laptop charging
- Smart digital display gives real-time wattage readouts
- Recharges itself in just 52 minutes with a 140W charger
- 24-month stress-free warranty included
❌ Cons
- No built-in cables — you must carry your own
- Heavier than the 25,000mAh model at 22 oz
Anker Power Bank (25K, 165W, Built-In Cables)
25,000mAh | 165W Total | 5 Ports (3 USB-C) | 6.18 x 2.13 x 1.93 in | 1.31 lbs
- 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 is the power bank I take on trips where I don’t want to fuss with extra cables. The built-in retractable USB-C cable extends up to 2.3 feet and is rated for 20,000 retractions, plus there’s a second 0.98-foot cable that doubles as a carrying strap. With three 100W USB-C ports, I can charge my MacBook, iPhone, and a friend’s phone all at once. It hits 30% charge in just 22 minutes, which is impressive. My biggest gripe is the 18-month warranty is shorter than the 737’s 24-month coverage.
✅ Pros
- Two built-in USB-C cables (one retractable, one strap)
- Triple 100W USB-C ports for charging up to 4 devices at once
- Ultra-fast recharge to 30% in just 22 minutes
- Lighter than the 737 at 1.31 lbs despite higher capacity
❌ Cons
- 18-month warranty is shorter than the 737’s 24-month plan
- No single port delivers the 737’s 140W speed
Which One Should You Buy?
After testing both of these Anker power banks with my own laptop and phone, I can tell you there’s no universal winner — the right choice depends entirely on whether you value raw charging speed or grab-and-go convenience. Let me walk you through who each one suits best.
Anker 737 Power Bank is right for you if…
- You need the fastest possible single-port laptop charging with a full 140W from Power Delivery 3.1
- You want real-time power insights from the smart display showing exact output wattage and recharge time
- You prefer a longer 24-month warranty and don’t mind carrying your own USB-C cables
Anker 25,000mAh Power Bank (Built-In Cables) is right for you if…
- You hate fumbling for cables — the built-in retractable cable extends 2.3 feet and lasts 20,000 retractions
- You frequently charge multiple devices at once with three 100W USB-C ports available
- You want the highest capacity at 25,000mAh in a lighter package (1.31 lbs) with ultra-fast recharging to 30% in 22 minutes
❌ Who Should Skip All of These?
If you only need to top off a phone and never charge a laptop, both of these are overkill — a smaller 10,000mAh power bank will save you weight and cash. Also, if you need to run AC-powered devices like a mini-fridge or power tools, you’re better off looking at a portable power station instead of a USB power bank.
For the vast majority of laptop users I talk to, I recommend the Anker 737 — its 140W single-port speed and smart display make it the better tool for fast, informed laptop charging, and the 24-month warranty gives extra peace of mind. But if you’re a traveler who values simplicity and hates carrying extra cables, the 25,000mAh model with built-in cables is a fantastic alternative.
Frequently Asked Questions
Which power bank charges a MacBook faster, the Anker 737 or the 25,000mAh model?
The Anker 737 wins this one hands down. It delivers a full 140W through a single USB-C port using Power Delivery 3.1, which is significantly faster than any single port on the 25,000mAh model. While the newer bank has three 100W ports, none of them match the 737’s peak speed for a single laptop.
Is the Anker 25,000mAh power bank worth the extra money over the Anker 737?
That depends on what you value. The 25,000mAh model costs more but gives you built-in retractable cables and a slightly higher total capacity at 25,000mAh versus 24,000mAh. I’d say it’s worth it if you hate carrying separate cables and frequently charge multiple devices at once. If raw laptop charging speed is your priority, stick with the 737.
Which power bank is better for traveling on a plane?
Both are perfectly fine for air travel since they comply with the 100Wh airline restriction. The Anker 737 measures 6.1 x 2.1 x 1.9 inches and weighs 22 ounces, while the 25,000mAh model is slightly longer at 6.18 inches but lighter at 1.31 pounds. I’d give a slight edge to the newer model for travel because the built-in cables mean one less thing to dig for at the security checkpoint.
Can the Anker 737 charge an iPhone 16 Pro faster than the 25,000mAh model?
For iPhone charging, they’re essentially the same speed. The 737 has 24,000mAh and can charge an iPhone 16 Pro 4.13 times, while the 25,000mAh model has a slightly higher capacity. Both support fast charging for iPhones, so your real decision should be about the other features like the display on the 737 or the built-in cables on the newer model.
Which power bank has better warranty coverage?
The Anker 737 gives you a 24-month stress-free warranty, while the 25,000mAh model only comes with an 18-month warranty. That’s a six-month difference, which matters if you’re planning to use this as a daily driver for years. I consider the 737 the better long-term investment for warranty coverage alone.
How many devices can I charge at once with each power bank?
The Anker 737 has 3 ports total (USB-C and USB-A) and can charge multiple devices, but the 25,000mAh model is the clear winner here with 5 total ports. It has three 100W USB-C ports plus a USB-A port and the built-in cables, letting you charge up to 4 devices simultaneously. If you’re charging a laptop, phone, tablet, and earbuds all at once, the newer model is your pick.
My Final Verdict
After all my testing, the Anker 737 Power Bank is my clear winner for laptop charging. Its 140W single-port output with Power Delivery 3.1 is unmatched for juicing up a MacBook fast, and the smart display showing real-time wattage is genuinely useful. The 25,000mAh model with built-in cables is a great runner-up for travelers who value convenience over raw speed, but it can’t match the 737’s peak charging performance or its 24-month warranty.
If you’re still on the fence, ask yourself this: do you want the fastest possible laptop charge and a longer warranty, or do you prefer built-in cables so you never forget one at home? That single question will tell you which Anker to buy.
