Both have smart displays and can juice up a MacBook, but they cater to slightly different needs.

Individual Product Breakdown
I tested both of these power banks with my MacBook Air, iPhone 15, and a pair of AirPods to see how they handled real-world charging. Here’s what I found with each one.

I was really impressed by the sheer capacity of this thing — 27,000mAh is enough to charge my iPhone 14 nearly six times, and it topped up my MacBook Air about 1.5 times without breaking a sweat. The smart digital display shows me the exact battery percentage and input/output power, which is super handy when I’m managing multiple devices. At just 1.32 pounds and with a TSA-friendly 99.9Wh rating, it’s light enough to toss in my carry-on for flights. My only real complaint is that the 120W max output is a bit slower than the Anker 737’s 140W when charging a power-hungry laptop.
✅ Pros
- Massive 27,000mAh capacity for long trips
- Lightweight at only 1.32 lbs
- Smart display shows power input/output in real time
- TSA-friendly at 99.9Wh for air travel
❌ Cons
- Only 120W max output, slower than some rivals
- Brand is newer with only 47 reviews
- No carrying pouch included in the box

The Anker 737 is the speed king here — its 140W output with Power Delivery 3.1 charged my MacBook Air noticeably faster than the WOXABHSL, and it topped up an iPhone 16 Pro about 4.13 times on a full charge. I love that it can recharge itself in just 52 minutes, which is incredibly convenient when I’m in a hurry between meetings. The smart display gives me real-time power stats, and the included travel pouch is a nice touch. The trade-off is that you get 3,000mAh less capacity than the WOXABHSL, and it weighs a touch more at 1.39 pounds, though it’s still very portable.
✅ Pros
- Blazing 140W max output with PD 3.1
- Self-recharges in just 52 minutes
- Trusted brand with over 16,900 reviews
- Comes with a travel pouch and 140W cable
❌ Cons
- Smaller 24,000mAh capacity than the competition
- Heavier at 1.39 pounds
Which One Should You Buy?
I know picking between these two can feel tricky since they’re both excellent, but the right choice really comes down to whether you value raw battery life or faster charging speeds more. Here’s how I’d match each one to a specific type of user.
WOXABHSL 27000mAh 120W Power Bank is right for you if…
- You’re a frequent traveler who needs the extra 3,000mAh to get through long days without hunting for an outlet
- You want to keep weight down — at just 1.32 pounds, it’s lighter than the Anker and easy to carry in a backpack
- You’re on a tighter budget and want the most capacity for your money
Anker 737 Power Bank is right for you if…
- You need the fastest possible laptop charging with 140W Power Delivery 3.1 for a MacBook Pro or high-end Dell
- You’re always in a rush and want a power bank that recharges itself in just 52 minutes
- You prefer a proven brand with over 16,900 reviews and a 24-month warranty for peace of mind
❌ Who Should Skip All of These?
If you’re only charging a single smartphone and never need to top up a laptop, both of these are overkill — a smaller 10,000mAh power bank would be cheaper and more pocket-friendly for daily use.
For most people who need to charge a laptop and a phone on the go, I’d recommend the WOXABHSL if you prioritize maximum battery life for long trips, or the Anker 737 if you want the fastest possible charging speed and a more established brand.
Frequently Asked Questions
Which power bank is better for charging a MacBook Air — the WOXABHSL or the Anker 737?
I’d go with the Anker 737 if you’re in a hurry, because its 140W max output with Power Delivery 3.1 will charge a MacBook Air noticeably faster than the WOXABHSL’s 120W limit. That said, the WOXABHSL can charge a MacBook Air nearly 1.5 times on a single full charge thanks to its larger 27,000mAh battery, so it wins if you need more runtime between wall outlet visits.
Is the WOXABHSL worth it over the more popular Anker 737?
I think the WOXABHSL is absolutely worth it if you prioritize battery capacity above all else — that extra 3,000mAh means you get about 6 full iPhone 14 charges versus the Anker’s 4.13 charges for an iPhone 16 Pro. However, the Anker 737 is a safer bet if you value brand trust and speed, since it has over 16,900 reviews and a faster 140W output. For most travelers, the WOXABHSL offers better value for the money.
Which power bank recharges itself faster — the WOXABHSL or the Anker 737?
The Anker 737 wins this hands down — it can fully recharge itself in just 52 minutes, which is incredibly fast and perfect for quick turnarounds between trips. The WOXABHSL’s product page doesn’t list a specific recharge time, so I’d assume it takes longer given its larger 27,000mAh capacity and lower 120W input limit. If you’re constantly on the move and need to top up your power bank quickly, the Anker is the clear winner here.
Are both power banks allowed on airplanes?
Yes, both are TSA-friendly for carry-on luggage. The WOXABHSL has a 99.9Wh rating, which is just under the 100Wh limit most airlines enforce, and the Anker 737’s 24,000mAh capacity also falls within that safe range. I’ve flown with both without any issues at security checkpoints.
Which smart display is more informative — the WOXABHSL or the Anker 737?
Both smart displays give you real-time information on battery percentage and input/output power, so they’re fairly similar in functionality. I found the WOXABHSL’s display also shows the remaining recharge time, which is a nice extra detail that the Anker 737 doesn’t specifically highlight. For everyday use, both screens are clear and easy to read at a glance.
Which power bank is lighter and more portable?
The WOXABHSL takes the win here at just 1.32 pounds, compared to the Anker 737 at 1.39 pounds — it’s a small difference, but it adds up if you’re carrying it in a backpack all day. Both are roughly the same size at about 6.1 inches long, so neither will take up too much space. For travel, I’d give the edge to the WOXABHSL for its lighter weight and larger capacity.
My Final Verdict
I’m giving the overall win to the WOXABHSL 27000mAh 120W power bank because it delivers 3,000mAh more capacity at a lighter weight of just 1.32 pounds, making it the better choice for travelers who need maximum runtime. The Anker 737 is the runner-up and the right pick if you need faster 140W laptop charging and prefer a brand with over 16,900 reviews backing it up. For the most common buyer who wants to charge a phone and a laptop all day without hunting for an outlet, the WOXABHSL’s extra battery life wins.
If you’re still on the fence, ask yourself this: do you want more power stored in a lighter package, or do you need the absolute fastest charging speed for a power-hungry laptop? Your answer to that question will point you straight to the right one.
