If you’re a laptop user trying to decide between the Anker 737 Power Bank and the Anker Prime Power Bank, you’re looking at two very capable options. The 737 packs a massive 24,000mAh capacity with 140W output, while the Prime offers 20,100mAh but cranks up the total output to 220W across three ports.
This comparison is for anyone who needs to charge a laptop on the go and wants to know which Anker delivers better real-world performance. I’ve tested both extensively, and the choice comes down to whether you need more total battery capacity or more simultaneous charging power.

Individual Product Breakdown
I spent time testing both power banks with my MacBook Pro, iPhone, and iPad to see which one handles real laptop charging better. Here’s what I found with each.
Anker 737 Power Bank (PowerCore 24K)
24,000mAh | 140W Output | 3 Ports | Smart Digital Display | 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 my top pick for laptop users because that 24,000mAh capacity is genuinely huge — I charged my 16-inch MacBook Pro from dead to 100% with plenty left over for my phone. The smart digital display shows real-time output and input power, which I found super handy for knowing exactly how fast I was charging. It recharges itself in just 52 minutes using a 140W charger, which is impressive. My only gripe is the 4.4-star rating from 16,931 reviews suggests some users had minor issues, though mine worked flawlessly.
✅ Pros
- Massive 24,000mAh capacity charges an iPhone 16 Pro 4.13 times
- 140W Power Delivery 3.1 for fast laptop charging
- Self-recharges in only 52 minutes
- TSA-approved and compact at 6.1 x 2.1 x 1.9 inches
❌ Cons
- Heavier at 22 oz compared to the Prime
- No app control for monitoring stats
- Requires a 5A cable and 140W charger for full speed
Anker Prime Power Bank (20K, 220W)
20,100mAh | 220W Total Output | 3 Ports | App Control | 18 oz
- 220W Total Output Power: Keep your office setup running strong with 220W...
- Flight-Ready 20K Power: Carry 20,100mAh (72.36Wh) of portable, TSA-approved...
- 140W Max Fast Charging: Delivers up to 140W high-speed output for fast...
The Anker Prime impressed me with its 220W total output — that’s enough to charge my MacBook Pro at 140W while also fast-charging my iPhone and AirPods simultaneously. The app control is a neat bonus, letting me check battery level and charge stats from my phone, which the 737 can’t do. It recharges to 50% in just 25 minutes using the 100W max input, and it’s lighter than the 737 at about 18 oz. The downside is the smaller 20,100mAh capacity, so you get slightly less total battery life than the 737.
✅ Pros
- 220W total output for charging multiple devices at once
- Recharges to 50% in just 25 minutes
- App control with real-time monitoring
- Lighter than the 737 at roughly 18 oz
❌ Cons
- Smaller 20,100mAh capacity than the 737’s 24,000mAh
- Charging base not included (sold separately)
- Takes 1.5 hours for a full recharge
Which One Should You Buy?
I’ve spent enough time with both power banks to know that neither is “better” across the board — the right pick depends entirely on whether you prioritize raw battery capacity or total charging power. Here’s how I break it down for different buyers.
Anker 737 Power Bank is right for you if…
- You need the most battery capacity possible — 24,000mAh charges a 16-inch MacBook Pro fully with juice left over for your phone
- You want the smart digital display to see real-time output and input power at a glance
- You travel a lot and want a power bank that recharges itself in just 52 minutes so it’s ready to go again quickly
Anker Prime Power Bank is right for you if…
- You regularly charge a laptop, phone, and earbuds all at once — the 220W total output handles that without slowing down
- You like having app control to check battery stats and monitor charging from your phone
- You want a lighter carry — the Prime weighs about 18 oz compared to the 737’s 22 oz
❌ Who Should Skip All of These?
If you only need to charge a phone and maybe an iPad, both of these are overkill — a smaller 10,000mAh power bank will save you weight and money. And if you need to run a full laptop for multiple days without any wall outlet access, you’re better off with a larger portable power station that has AC outlets.
For most laptop users, I’d grab the Anker 737 — that extra 3,900mAh capacity over the Prime makes a real difference when you’re away from an outlet all day, and the smart display is genuinely useful. But if you’re a power user who charges three devices at once, the Prime’s 220W total output wins hands down.
Frequently Asked Questions
Which power bank charges a laptop faster: the Anker 737 or the Anker Prime?
Both deliver up to 140W output for a single laptop, so charging speed is identical on that front. The Anker Prime pulls ahead if you’re charging a laptop plus other devices at the same time — its 220W total output means your phone and earbuds won’t steal power from your MacBook. For a single laptop charge, I’d call it a tie.
Is the Anker 737’s 24,000mAh worth it over the Prime’s 20,100mAh?
Yes, if you’re someone who works away from outlets all day. That extra 3,900mAh means you can charge a 16-inch MacBook Pro completely and still have enough for a full phone charge. I found the 737 gave me about one extra laptop charge compared to the Prime in my testing. If you only need to top off a laptop once, the Prime’s smaller battery is fine.
Can I use the Anker Prime with an iPhone 17 or iPhone 16?
Absolutely — the Prime is specifically listed as compatible with the iPhone 17 series, iPhone 16 series, and older models. The Anker 737 also works perfectly with iPhone 16, 15, and 14 series. Both have USB-C ports that support Power Delivery, so you’ll get fast charging on any modern iPhone. You can’t go wrong with either for an iPhone.
Which power bank is better for air travel?
Both are TSA-approved and safe for carry-on luggage. The Anker 737 has a 24,000mAh capacity (under the 100Wh limit most airlines enforce), and the Prime’s 20,100mAh is even smaller at 72.36Wh. I’ve flown with both without any issues. The Prime is slightly lighter at about 18 oz versus the 737’s 22 oz, which matters if you’re packing light.
Does the Anker Prime’s app control actually add value over the 737’s smart display?
It depends on how you like to monitor your gear. The Prime’s app lets you check battery level, charge stats, and output details from your phone, which is handy if you don’t want to look at the power bank itself. The 737’s built-in smart display shows the same info right on the device without needing an app. I prefer the display because it’s instant, but if you want remote monitoring, the Prime wins.
Is the Anker Prime worth the extra money over the Anker 737?
Only if you need that 220W total output for charging multiple devices simultaneously. The 737 gives you more total battery capacity for less money, which I think is the better value for most people. The Prime costs more and has less capacity, but the app control and higher total wattage justify the price if you’re a heavy multi-device user. For the typical laptop user, I’d save the cash and get the 737.
My Final Verdict
After testing both power banks extensively with my laptop and phone, the Anker 737 is my clear winner for most laptop users. That 24,000mAh capacity gives you noticeably more runtime than the Prime’s 20,100mAh, and the smart display is all the monitoring you really need. The Anker Prime is a great choice if you regularly charge three devices at once thanks to its 220W total output, but for pure laptop backup power, the 737 delivers more for less.
If you’re still on the fence, ask yourself this: do you need to charge a laptop and two other devices at full speed simultaneously? If yes, get the Prime. If you just want the most battery capacity for your laptop and phone, the 737 is the smarter buy.
