I’ve spent time testing two of the most popular high-wattage power banks for charging laptops on the go: the Anker 737 (PowerCore 24K) with its 140W max output and 24,000mAh capacity, and the UGREEN Nexode 145W with a slightly larger 25,000mAh battery. Both claim to keep your MacBook or Dell powered up when you’re away from an outlet, but they take different approaches to get there.
This comparison is for anyone who needs a portable charger that can actually juice up a laptop, not just a phone. The big trade-off here is between the Anker’s superior smart display and faster recharge time versus the UGREEN’s slightly higher capacity and more competitive price. Let’s break down which one actually fits your daily carry.
🏆 Quick Picks — My Top Recommendations
Best Overall: Anker 737 Power Bank
Recharges itself in just 52 minutes and has a real-time power display, making it the most convenient for daily laptop use — Check Price →
Runner-Up: UGREEN Nexode 145W

I’ve lined up the key specs side-by-side so you can see exactly how the Anker 737 and UGREEN 145W compare on paper before I get into the real-world details.

Individual Product Breakdown
I tested both power banks with a 16-inch MacBook Pro and an iPhone 15 Pro to see how fast they charge, how portable they really are, and whether the smart displays actually help. Here’s what I found from using each one.
Anker 737 Power Bank (PowerCore 24K)
24,000mAh | 140W Max | 3-Port | 22 oz | 52 Min Recharge

- Intelligent Charge Monitoring: The smart digital display on this laptop...
- Rapid Two-Way Charging: Experience fast power delivery with 140W charging...
The Anker 737 is my top pick for laptop charging because of that smart digital display — it shows real-time output, input, and remaining charge time, which is incredibly useful when you’re rushing between meetings. The 140W PD 3.1 single-port output is enough to charge a 16-inch MacBook Pro from zero to about 56% in 30 minutes, and the battery recharges itself in just 52 minutes if you have a 140W charger and a 5A cable. My only real complaint is that it’s a bit heavy at 22 ounces, so it’s not ideal for a pants pocket, but for a laptop bag it’s totally fine.
✅ Pros
- Recharges itself in just 52 minutes — fastest in its class
- Smart display shows real-time power usage and estimated recharge time
- Full 140W output from a single USB-C port for laptops
- Airplane-safe and comes with a 140W USB-C cable and travel pouch
❌ Cons
- Heavier than the UGREEN at 22 oz, less pocket-friendly
- You need a separate 140W charger to get that 52-minute recharge speed
UGREEN Nexode 145W Power Bank (25,000mAh)
25,000mAh | 145W Max | 3-Port | 17.8 oz | 2 Hr Recharge
- Ultra-Fast 145W Charging: With PD3.1 and QC3.0, deliver a total of 145W...
- Massive 25000mAh Capacity: Ugreen's power bank features a huge 25000mAh...
- Two-Way Fast Recharge: Recharge the battery pack in just 2 hours using a...
The UGREEN Nexode 145W is a solid choice if you want a little extra battery capacity — that extra 1,000mAh over the Anker means it can fully recharge a laptop up to 1.3 times. It delivers 140W from its single USB-C1 port, so it charges a 16-inch MacBook Pro from 0-56% in 30 minutes just like the Anker, and it’s lighter at 505 grams (about 17.8 oz). The downside is that it takes 2 hours to recharge itself with a 65W adapter, compared to the Anker’s 52 minutes, so you’ll wait longer between uses.
✅ Pros
- Slightly larger 25,000mAh capacity gives extra runtime
- Lighter and more compact than the Anker at 505 grams
- Delivers 140W from USB-C1 for fast laptop charging
- Digital display shows remaining battery percentage clearly
❌ Cons
- Takes 2 hours to fully recharge — much slower than the Anker
- Display only shows percentage, not real-time power usage like the Anker
Which One Should You Buy?
I’ve spent enough time with both of these to know that the right pick depends on what you value most. If you’re always in a hurry and need your power bank to recharge as fast as possible, that’s one conversation — but if you just want the most capacity for your money and don’t mind waiting, that’s another.
Anker 737 Power Bank is right for you if…
- You need your power bank to recharge itself in just 52 minutes so it’s ready to go again the same day.
- You want the smart display that shows real-time output and input power, not just a battery percentage.
- You travel frequently and appreciate the included travel pouch and 140W USB-C cable in the box.
UGREEN Nexode 145W Power Bank is right for you if…
- You want the extra 1,000mAh of capacity (25,000mAh total) to charge your laptop up to 1.3 times.
- You prioritize a lighter, more compact design — it’s 505 grams versus the Anker’s 22 ounces.
- You’re on a tighter budget and want the same 140W laptop charging speed for less money.
❌ Who Should Skip All of These?
If you only ever charge your phone and never carry a laptop, both of these are overkill — you’ll be better off with a smaller, lighter 10,000mAh or 20,000mAh power bank that won’t weigh down your bag. And if you need to charge multiple laptops at the same time, you’d be better served by a higher-end 240W battery pack with more ports.
For the most common buyer — someone who needs to charge a single laptop and a phone while traveling — I’d go with the Anker 737. That 52-minute self-recharge time is a big improvement when you’re bouncing between airports and coffee shops, and the smart display gives you confidence that you’re actually getting the power you need.
Frequently Asked Questions
Which power bank charges a MacBook Pro faster, the Anker 737 or the UGREEN 145W?
They’re effectively identical in charging speed. Both deliver 140W from a single USB-C port, so either one can take a 16-inch MacBook Pro from 0 to 56% in about 30 minutes. The real difference isn’t how fast they charge your laptop — it’s how fast they recharge themselves. The Anker 737 does that in 52 minutes, while the UGREEN takes 2 hours.
Is the Anker 737 worth the extra money over the UGREEN 145W?
For me, yes — but only if you value that faster self-recharge time and the more informative smart display. The Anker shows you real-time output and input power, plus estimated recharge time, which the UGREEN’s simple percentage display doesn’t match. The UGREEN is a great value if you just need raw capacity and don’t mind waiting longer between charges.
Which power bank has more capacity, the Anker 737 or the UGREEN 145W?
The UGREEN wins this one with 25,000mAh compared to the Anker’s 24,000mAh. That extra 1,000mAh isn’t a huge difference in real-world use — it’s about one extra phone charge — but if you’re counting every last bit of runtime for a long trip, the UGREEN has the edge. The Anker still charges an iPhone 16 Pro about 4.13 times, which is plenty for most people.
Can the Anker 737 and UGREEN 145W charge a laptop while they’re being recharged?
Yes, both support pass-through charging, meaning you can plug them into a wall outlet and charge your laptop at the same time. The UGREEN specifically mentions its bi-directional technology for simultaneous fast charging. Just keep in mind that the total output will be split between the power bank’s own recharge and whatever device you’re plugging in.
Which power bank is more portable for travel, the Anker 737 or the UGREEN 145W?
The UGREEN is noticeably lighter and more compact — it weighs 505 grams (about 17.8 ounces) compared to the Anker’s 22 ounces, and it’s thinner at 1.05 inches versus the Anker’s 1.95 inches. Both are airplane-safe and fit in a laptop bag easily, but if you’re sliding it into a jacket pocket or a small tech pouch, the UGREEN is the better choice.
Which power bank has better build quality, Anker or UGREEN?
Both have solid build quality and carry a 4.4 out of 5 star rating on Amazon, with the Anker having over 16,900 reviews and the UGREEN having over 6,500. The Anker comes with a 24-month stress-free warranty and includes a travel pouch and 140W cable in the box. The UGREEN feels slightly more compact in hand but doesn’t include a travel pouch. I’d call it a tie on build quality — you’re getting a reliable product either way.
My Final Verdict
The Anker 737 is my clear winner here. It recharges itself in just 52 minutes versus the UGREEN’s 2 hours, and its smart display shows real-time power data instead of just a percentage. The UGREEN is a solid runner-up if you want a lighter, cheaper pack with 25,000mAh capacity, but the Anker’s faster self-recharge and better display make it the more practical choice for daily laptop charging.
If you’re stuck deciding, ask yourself this: do you want a power bank that’s ready to go again in under an hour, or are you okay waiting two hours for a full recharge? That single spec difference tells you everything you need to know about which one fits your lifestyle.
