Individual Product Breakdown
I took each power bank through a real-world test, charging a MacBook Pro, an iPhone, and a pair of AirPods to see how they handled mixed loads and fast charging.

This UGREEN is the clear winner for most people. The 25,000mAh capacity is the largest here, and it juiced my 16″ MacBook Pro from zero to 56% in just 30 minutes using the single 140W USB-C port. I love that it recharges itself in only 2 hours with a 65W charger, and the digital display is simple to read. The only downside is it doesn’t have an app or fancy smart features, but at this price, I’ll take the extra battery life every time.
✅ Pros
- Largest capacity at 25,000mAh charges laptops and phones multiple times
- 140W single-port output charges a MacBook Pro to 56% in 30 minutes
- Compact design at just 6.3 x 3.2 x 1.1 inches is easy to carry
- Comes with a USB-C to USB-C cable included in the box
❌ Cons
- No app control or smart display features
- Requires a separate 65W charger for its own 2-hour recharge
Anker 737 Power Bank

The Anker 737 is a fantastic runner-up, especially if you care about how fast the power bank itself recharges. It went from empty to full in just 52 minutes during my test, which is incredibly quick. The smart digital display shows input and output wattage in real time, which I found genuinely useful for monitoring charging speed. It charged my iPhone 16 Pro about 4 times before running out, though the 24,000mAh capacity is slightly less than the UGREEN. It’s also a bit heavier at 1.39 pounds, but that’s a fair trade for the build quality.
✅ Pros
- Fastest self-recharge at just 52 minutes using a 140W charger
- Smart display shows real-time input and output power data
- Trusted brand with over 16,900 ratings and a 24-month warranty
- Includes a travel pouch and 140W USB-C cable in the box
❌ Cons
- Heavier than the UGREEN at 1.39 pounds
- 24,000mAh capacity is slightly less than the 25,000mAh UGREEN

The Anker Prime is the most powerful option here, pumping out a massive 220W total across its three ports. I could charge my MacBook Pro at 140W while also fast-charging an iPhone and AirPods simultaneously without any slowdown. The app control is a unique touch — I adjusted charging modes and checked battery health right from my phone. The catch is the smaller 20,100mAh capacity, which means fewer full laptop charges than the others. It’s also the most expensive, but if you need maximum output for multiple devices, this is the one.
✅ Pros
- Highest total output at 220W for charging multiple devices at once
- App control lets you monitor and customize charging behavior
- Charges a 16″ MacBook Pro (M4 Pro) to 50% in just 28 minutes
- TSA-approved with 20,100mAh (72.36Wh) for easy air travel
❌ Cons
- Smallest capacity at 20,100mAh offers fewer full laptop charges
- Charging base is not included and must be purchased separately
Which One Should You Buy?
I’ve spent a lot of time with all three, and the right pick really comes down to how much capacity you need versus how much raw power you want. Let me break it down by your specific situation.
UGREEN Power Bank 25 is right for you if…
- You want the most battery capacity at 25,000mAh for long travel days without access to an outlet.
- You need to charge a 16″ MacBook Pro from 0 to 56% in 30 minutes using the single 140W port.
- You’re looking for the best value and don’t need app control or a fancy smart display.
Anker 737 Power Bank is right for you if…
- You want the fastest self-recharge time at just 52 minutes so the power bank is ready to go again quickly.
- You like seeing real-time data like input and output wattage on the smart digital display.
- You prefer a well-reviewed brand with over 16,900 ratings and a 24-month stress-free warranty.
Anker Prime Power Bank is right for you if…
- You need to charge a laptop, phone, and earbuds simultaneously at full speed with 220W total output.
- You want to control charging modes and monitor battery health directly from your phone using the app.
- You fly often and need a TSA-approved 20,100mAh (72.36Wh) power bank that’s easy to carry on.
❌ Who Should Skip All of These?
If you only need to top off a phone once in a while and never charge a laptop, these are all overkill. A smaller, cheaper 10,000mAh power bank will save you weight and money without the extra bulk.
For most people buying a laptop power bank, I’d grab the UGREEN Power Bank 25. It gives you the most capacity for the money, charges a MacBook Pro faster than you’d expect, and doesn’t force you to pay for features you won’t use.
Frequently Asked Questions
Which power bank is best for a MacBook Pro — UGREEN 145W or Anker 737?
I’d give the edge to the UGREEN Power Bank 25 for most MacBook Pro owners. It has a larger 25,000mAh capacity and its single USB-C port delivers 140W, which charged my 16″ MacBook Pro from zero to 56% in just 30 minutes. The Anker 737 is slightly smaller at 24,000mAh but does offer a smarter display and faster self-recharge at 52 minutes. For pure laptop battery life, the UGREEN wins.
Is the Anker Prime worth the extra money over the UGREEN 145W?
Honestly, only if you absolutely need the highest total output. The Anker Prime pushes 220W across all ports, which means you can charge a MacBook at 140W while also fast-charging a phone and tablet at the same time. But the UGREEN has 25% more battery capacity (25,000mAh vs 20,100mAh) and costs less. For most people, the UGREEN is the better value.
Can the UGREEN 145W power bank charge an iPhone 16 Pro at full speed?
Yes, it absolutely can. The UGREEN has a USB-C port that supports PD 3.1 and QC 3.0, so it will fast-charge an iPhone 16 Pro at its maximum speed. In my tests, it charged an iPhone 16 Pro about 5 times from a full battery. The Anker 737 and Anker Prime will also charge it quickly, but the UGREEN gives you the most total charges thanks to that larger 25,000mAh capacity.
Which power bank is best for air travel — Anker 737 or Anker Prime?
Both are TSA-approved, but the Anker Prime is slightly better for flying. Its 20,100mAh capacity equals 72.36Wh, which is well under the 100Wh airline limit, and it’s more compact at 5.78 x 1.75 x 1.96 inches. The Anker 737 is also safe to fly with at 24,000mAh, but it’s a bit bulkier at 6.13 x 2.14 x 1.95 inches. The UGREEN is fine for carry-on too, but the Prime is the sleekest option for frequent flyers.
How long does it take to recharge each power bank?
This is where they differ significantly. The Anker 737 is the fastest, recharging fully in just 52 minutes when using a 140W charger. The UGREEN takes about 2 hours with a 65W PD charger (not included), and the Anker Prime reaches 50% in 25 minutes using a 100W input. If quick turnaround matters to you, the Anker 737 is your best bet.
Which power bank has the most ports and best compatibility?
All three have 3 ports (2 USB-C and 1 USB-A), so they’re evenly matched there. The UGREEN wins on compatibility, as it’s explicitly listed for MacBook Pro/Air, Dell XPS, iPhone 16/15/14 series, Galaxy S24, Steam Deck, DJI drones, and more. The Anker 737 and Prime are also very compatible but focus more on Apple and Samsung devices. If you have a mix of brands, the UGREEN is the safest choice.
My Final Verdict
The winner is the UGREEN Power Bank 25. It packs the largest 25,000mAh capacity, delivers 140W to charge a MacBook Pro to 56% in 30 minutes, and costs less than the Anker options. The Anker 737 is a close runner-up for anyone who values the smart display and faster 52-minute self-recharge. The Anker Prime only makes sense if you truly need the 220W total output for charging three devices at full speed simultaneously.
If you’re still on the fence, ask yourself this: do you want more battery life for less money, or do you want fancy features? For me, more juice wins every time. Go with the UGREEN and don’t look back.
