Anker 737 Power Bank Review: 140W Travel Power

If you’ve ever watched a laptop battery drain to single digits in an airport gate area with no free outlet in sight, you already know the problem the Anker 737 Power Bank is built to solve. It pushes 140W over USB-C, carries 24,000mAh of cells, and puts a live readout on the front so you know exactly what’s happening.

That combination of high-wattage USB-C output, airline-legal capacity, and a real-time display puts the 737 in a narrow group of power banks that can meaningfully recharge a laptop, not just top off a phone.

At roughly 1.4 pounds and 6.1 inches long, it’s closer to a hardcover paperback than a phone accessory. That weight buys you three ports, two-way 140W charging, and enough headroom to run a MacBook and a phone at the same time.

Bottom Line

For frequent flyers, remote workers, and anyone whose laptop battery gives out before the day does, this is one of the most capable travel banks you can carry through security.

Overview: Anker 737 Power Bank

Model A1289 sits at the top of the brand’s non-Prime portable lineup, pairing a 24,000mAh lithium-ion pack with Power Delivery 3.1 support. Three ports, two USB-C and one USB-A, handle simultaneous charging, and the shell measures 6.13 x 2.14 x 1.95 inches in matte black.

Anker rates the pack for 4.13 full iPhone 16 Pro charges or 1.33 charges of a 2024 13-inch iPad Pro. A 24-month warranty covers it, and the box includes a 140W-rated USB-C cable plus a travel pouch.

If you want context on where this fits against the rest of the range, our roundup of the best Anker powerbank options covers smaller and larger siblings.

140W USB-C Laptop Charging

The headline number is real, and it changes what a power bank can do. Power Delivery 3.1 on the primary USB-C port delivers up to 140W, enough to fast-charge a 16-inch MacBook Pro at close to wall-adapter speed instead of trickling in a few percent per hour.

Two conditions matter: you need the bundled 5A cable, or an equivalent 240W-rated one, and the laptop itself has to negotiate the higher voltage. Older USB-C laptops capped at 60W or 100W will still charge, just at their own ceiling.

Input works the same way. Paired with a 140W wall charger, the pack refills quickly, which is the difference between an overnight top-up and a coffee-break one.

24,000mAh Capacity for Long Days

Capacity here translates to about 87Wh, close to the practical ceiling for a carry-on battery. In real terms, that means a MacBook Air from empty to full with charge left over for a phone, or a long weekend of phone-and-earbuds use without touching a wall socket.

Expect roughly 80 to 85 percent of the rated capacity to reach your devices after conversion losses. That’s normal for any lithium pack.

For lighter loads, a smaller unit like the Anker 10000mAh portable charger makes more sense. The 737 earns its size when a laptop is part of the equation.

Smart Display and Three-Port Flexibility

The front-mounted screen is the feature owners mention most often, and for good reason. It shows live input and output wattage, remaining percentage, and an estimated time to full, so you can tell at a glance whether your cable is actually negotiating high power or quietly limiting you to 15W.

Port allocation is straightforward:

Port	Solo output	Notes
USB-C1	Up to 140W	Primary laptop port, also the fast input
USB-C2	Up to 100W	Second high-power device
USB-A	Up to 18W	Legacy cables and accessories

Total shared output tops out at 170W across all three, so a laptop, a phone, and earbuds can run together without one starving the others.

Is It Practical for Air Travel and Daily Carry?

At 87Wh, the pack sits under the 100Wh TSA limit, so it goes in your carry-on without airline pre-approval. Owners report clearing security in both the US and EU without questions.

Daily carry is a different calculation. At about 22 ounces, it’s noticeable in a jacket pocket and unremarkable in a backpack or tote, which is where most owners keep it.

The matte finish resists fingerprints reasonably well, though the clear plastic panel over the display picks up scuffs faster than the rest of the body. A sleeve or the included pouch helps if that bothers you.

Pros and Cons

Pros

• Genuine 140W PD 3.1 output charges most USB-C laptops at full speed
• Live wattage and time-to-full display removes guesswork about charging rates
• Fast recharging when paired with a high-wattage wall adapter
• Under the 100Wh airline threshold for carry-on baggage
• Includes a 140W-rated cable and travel pouch, which many competitors omit
• Two USB-C ports plus USB-A covers old and new gear

Cons

• Heavier and thicker than most people expect from photos
• Display window scratches more easily than the surrounding shell
• No wall charger included, so 140W input requires a separate purchase
• Printed instructions are small and hard to read
• Premium pricing compared with 100W alternatives

What Customer Reviews Reveal

Owner feedback clusters around two themes: charging speed impresses, and weight surprises. Multiple buyers describe fully recharging a MacBook Pro and an iPad Pro in a single session, while several note the pack still had reserve after two to three weeks of moderate phone use.

The display draws consistent praise for showing exact draw and remaining capacity. One recurring complaint is that the plastic covering it marks easily.

Weight comes up in nearly every critical review, though most of those same buyers say it stays fine in a backpack. A handful of international reviewers flagged confusion over what ships in the box, and one noted the manual’s tiny print. Feedback across the broader Anker powerbank lineup follows similar patterns.

Conclusion

The 737 makes the most sense if you carry a USB-C laptop and regularly work away from outlets. The 140W ceiling and 24,000mAh reserve cover a full workday of laptop use, and the display tells you where you stand without connecting an app.

If your charging needs stop at phones and tablets, a lighter 10,000mAh or 20,000mAh pack saves you a pound and a fair amount of money. Buyers who want even more headroom for multiple laptops should look at the Anker Prime 27,650mAh 250W charger instead.

Pair the 737 with a compact 140W GaN wall adapter and you have a two-piece travel kit that handles a laptop, a phone, and accessories from one bag pocket.

Frequently Asked Questions

Is the Anker 737 Power Bank allowed on airplanes?

Yes. Its 24,000mAh capacity works out to roughly 87Wh, under the FAA and TSA 100Wh threshold for lithium batteries carried without airline approval. It must travel in your carry-on, never in checked baggage.

Can the Anker 737 charge a laptop while charging a phone?

Yes. With three ports and up to 170W of combined output, a laptop on the primary USB-C port and a phone on the second port both charge at usable speeds. The per-port maximum drops when multiple devices are connected, so expect a laptop to draw less than the full 140W in that scenario.

How long does it take to recharge the Anker 737 Power Bank?

With a 140W USB-C wall charger and the included 5A cable, the pack reaches a substantial charge in under an hour and full in roughly 90 minutes. Using a standard 30W or 65W adapter stretches that to several hours, since input speed is limited by the charger.

Does the Anker 737 include a charging cable?

Yes. A 140W-rated USB-C to USB-C cable ships in the box along with a travel pouch and a welcome guide. No AC wall adapter is included, so you’ll need a high-wattage charger separately to hit full input speed.

Is the Anker 737 Power Bank too heavy for everyday carry?

At about 22 ounces, it’s too heavy for a pocket but fine for a backpack, messenger bag, or tote. Owners who carry it daily generally keep it in a bag rather than on their person.

Those who only charge phones tend to prefer something half the size.
