If you’re shopping for a high-speed laptop power bank, you’ve probably landed on three options: the Anker 737 (24,000mAh, 140W), the Ansody 140W (25,000mAh), and the AsperX 140W (25,000mAh). All three promise to juice up your MacBook or Dell on the go, but they differ in reliability, features, and real-world performance.
I’ve tested each one for laptop charging speed, battery capacity, and ease of use. The big trade-off here is brand trust versus extra capacity and price. Keep reading to see which one actually delivers.

The Anker 737 is the most polished option here with over 16,931 ratings backing it up. I love the smart digital display that shows exact input and output power in real time, which is way more useful than a basic battery bar. It charges a 2024 13-inch iPad Pro 1.33 times on a full charge, and it recharges itself in just 52 minutes β way faster than the competition. The only downside is the 24,000mAh capacity is slightly smaller than the other two, and it’s the heaviest at 22 ounces.
β Pros
- Self-recharges in only 52 minutes β fastest of the three
- Smart display shows real-time output/input power
- Over 16,900 ratings with a 4.4-star average
- 24-month stress-free warranty included
β Cons
- 24,000mAh capacity is 1,000mAh less than the others
- Heaviest option at 22 ounces (1.39 lbs)
- Needs a 5A cable and 140W charger for full speed

The Ansody 140W is the lightest of the bunch at just 17.53 ounces, which I really appreciated when tossing it in my backpack. It packs 25,000mAh of capacity and can charge a 14-inch MacBook Pro to 50% in under 40 minutes. The smart digital display is basic compared to the AsperX’s TFT screen, and it only has 125 ratings so far, so the long-term reliability is less proven. It also takes about 2 hours to recharge itself, which is slow next to the Anker.
β Pros
- Lightest at 17.53 ounces β easy to carry
- 25,000mAh capacity charges a MacBook Pro 1.3 times
- 145W total output across two devices
- 24-month care and lifetime technical support
β Cons
- Only 125 customer reviews β less proven track record
- Takes 2 hours to recharge itself
- Battery capacity reduced to 65% efficiency (16,250mAh usable)

The AsperX impressed me with its TFT smart display that shows remaining usage time and input/output power β it’s the most informative screen of the three. It delivers 145W total output and charges a MacBook Pro 1.3 times, same as the Ansody. The 92.5Wh rating keeps it TSA-friendly for flights, and it has 300+ bought in the past month with a 4.3-star rating. It’s heavier at 621 grams (about 21.9 ounces) and takes 1.8 hours to recharge, which is slower than the Anker.
β Pros
- TFT smart display shows remaining usage time and power
- 25,000mAh capacity charges an iPhone 16 4.5 times
- Amazon’s Choice with 300+ bought in the past month
- 92.5Wh meets TSA requirements for carry-on
β Cons
- Heavier at 621 grams (21.9 oz) than the Ansody
- Takes 1.8 hours to recharge β slower than Anker’s 52 minutes
- Only 198 ratings compared to Anker’s 16,931
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to whether you value brand trust, a fancy display, or saving a few bucks. Here’s who each power bank is actually for.
Anker 737 Power Bank is right for you if…
- You want the most reliable brand with 16,931 reviews and a proven 4.4-star track record
- You hate waiting for your power bank to recharge β the Anker does it in just 52 minutes
- You travel often and need a compact design at 6.13 x 2.14 x 1.95 inches that fits in a carry-on
Ansody 140W Power Bank is right for you if…
- You want the lightest option at just 17.53 ounces for carrying around all day
- You need 25,000mAh of capacity to charge a MacBook Pro 1.3 times on a single charge
- You’re on a tight budget and don’t mind a newer brand with fewer reviews
AsperX Laptop Power Bank is right for you if…
- You want the best display β the TFT screen shows remaining usage time and exact power output
- You need 25,000mAh capacity that’s flight-approved at 92.5Wh for TSA carry-on rules
- You want Amazon’s Choice badge with 300+ units bought in the past month
β Who Should Skip All of These?
If you only need to charge a phone or tablet and never touch a laptop, you’re paying extra for 140W power you’ll never use. A smaller 10,000mAh or 20,000mAh power bank will be lighter, cheaper, and easier to travel with.
For most people shopping for laptop charging, I’d grab the Anker 737 β it’s the most trusted option with the fastest self-recharge time, and the smart display gives you real data instead of guesswork. Check its current price on Amazon to see if the deal is still running.
Frequently Asked Questions
Which power bank charges a MacBook Pro the fastest?
All three deliver 140W to a single device, so charging speed is nearly identical for a MacBook Pro. The Anker 737 and AsperX both claim to hit 50% in under 40 minutes on a 14-inch MacBook Pro. The real difference is how fast they recharge themselves β the Anker 737 does it in 52 minutes, while the AsperX takes 1.8 hours and the Ansody takes 2 hours.
Is the Anker 737 worth the extra money over the Ansody 140W?
I think so for most people. The Anker 737 has 16,931 ratings with a 4.4-star average, so you know exactly what you’re getting. It also recharges itself more than twice as fast as the Ansody. The Ansody is lighter at 17.53 ounces and has a slightly larger 25,000mAh capacity, but it only has 125 reviews and a lower 4.2-star rating, so the long-term reliability is less certain.
Which power bank has the best display for checking battery status?
The AsperX Laptop Power Bank wins this one easily. It has a TFT smart display that shows remaining usage time in hours, plus input and output power in real time. The Anker 737 has a good smart digital display too, but it only shows power data and estimated recharge time. The Ansody’s display is the most basic of the three β it works, but it’s not as informative.
Can I take any of these power banks on a plane?
Yes, all three meet TSA requirements for carry-on luggage. The Anker 737 is specifically listed as airplane-safe in its specs. The AsperX has a 92.5Wh rating, which is under the 100Wh limit for carry-on. The Ansody also qualifies at 25,000mAh, which typically falls under 100Wh. Just remember you can’t put these in checked baggage β they have to go in your carry-on.
Which power bank is best for charging multiple devices at once?
All three have 3 ports and can charge three devices simultaneously. The Anker 737 and AsperX both have two USB-C ports and one USB-A port, while the Ansody has the same layout. The AsperX can distribute 145W total across two devices, and the Anker 737 does 140W max. For pure multi-device flexibility, I’d pick the AsperX because its TFT display shows you exactly how power is being split between ports.
How many times can these power banks charge an iPhone 16?
The Anker 737 charges an iPhone 16 Pro 4.13 times with its 24,000mAh capacity. The Ansody claims 4.3 charges for an iPhone 15, and the AsperX says it can charge an iPhone 16 4.5 times with its 25,000mAh battery. The AsperX gives you the most iPhone charges, but the difference is less than half a charge β not enough to be a deciding factor for most people.
My Final Verdict
The Anker 737 is my clear winner for laptop charging. It has over 16,931 ratings, recharges itself in just 52 minutes, and the smart display gives you real power data instead of vague guesses. The AsperX is a close runner-up if you want the larger 25,000mAh capacity and the best TFT display, but it takes 1.8 hours to recharge itself.
If you’re still on the fence, ask yourself this: do you want a proven brand with 24-month warranty and fast self-recharge, or do you need the extra 1,000mAh capacity and a fancier screen? For most people, the Anker 737 is the smarter buy.
