Who Should Buy This#
The Anker 737 Power Bank is for people who have outgrown tiny phone-only battery packs. It gives you enough capacity and output to keep a laptop, tablet, phone, and smaller accessories alive through a long travel day, a delayed flight, or a full afternoon away from a desk.
It also makes sense for anyone trying to carry fewer chargers overall. Instead of packing one brick for the wall and another weak battery for emergencies, you get a single pack that can do serious work when your main device starts dying.
Perfect for:
- Frequent travelers who need reliable backup power for a USB-C laptop, phone, earbuds, and handhelds on long transit days
- Hybrid workers who bounce between office, home, and coffee shops and cannot risk a dead laptop before the day is over
- Students carrying one USB-C laptop and several smaller devices who want one battery that actually matters
- Mobile creators who charge cameras, wireless mics, monitors, or phones on location and need more than a pocket-sized battery can deliver
Design & Build Quality#
The 737 looks more serious than the average plastic slab power bank. It has a dense, upright shape with a dark shell, metallic face, and a small screen that gives it more of a compact power tool vibe than a disposable accessory vibe. That matters more than it sounds. If you are paying for a premium battery pack, it should feel built to survive daily travel instead of getting tossed in a drawer after a month.
At 6.13 × 2.15 × 1.95 inches and about 22.22 ounces, it is not a jeans-pocket battery. This is a bag carry, not a pocket carry. The upside is that the footprint works well in a backpack, tote, or tech pouch, and the weight feels justified once you realize how much output and capacity Anker squeezed into the body.
The front display is one of the best quality-of-life touches here. Instead of guessing from four blinking lights, you can quickly check remaining battery, charging behavior, and other live status data. Once you get used to that, basic LED indicators feel primitive.
Key Features#
140W Charging That Can Handle Real Laptops#
The headline feature is 140W max output, which puts the 737 in a different class from the many 20W to 65W battery packs sold as laptop-capable. That extra headroom matters if you charge larger USB-C notebooks, especially when you want the battery to keep up instead of merely slowing the drain.
In practical terms, this is the kind of power bank you buy when a MacBook, high-end Windows ultrabook, or power-hungry tablet is part of your everyday carry. It is not just for emergency phone top-ups. It is built to keep main devices running.

24,000mAh Capacity That Is Big Enough to Matter#
Anker rates the pack at 24,000mAh, which is the sweet spot for people who want serious backup power without stepping into oversized travel-brick territory. It gives you enough reserve for multiple phone charges or a meaningful partial refill on a laptop, which is exactly what most buyers are actually looking for.
The official spec page also keeps it within airline-friendly carry-on territory, so it is easier to recommend for flights than extra-large battery packs that raise eyebrows at security. You get real endurance without making travel awkward.
Smart Digital Display Beats Guessing#
A lot of power banks still rely on tiny LEDs that tell you almost nothing. The 737 uses a smart digital display that gives you a much clearer read on what is happening. You can see battery status at a glance and make better decisions about when to recharge the pack or which device to prioritize.
That sounds small until you are traveling with several devices and limited wall time. Better visibility means less guesswork, fewer surprises, and less unnecessary charging anxiety.
Two USB-C Ports and One USB-A Keep It Flexible#
The port mix is exactly what most people still need in the real world: two USB-C ports for current laptops, tablets, and phones, plus one USB-A for older accessories and backup cables. That keeps the pack useful during the messy transition period where your main gear is modern but part of your cable pile is not.
It also means you can charge multiple devices from one pack without resorting to dongles. That is valuable on flights, in cafes, or at conferences where power outlets are limited and every cable has to earn its place.
Fast Recharging Makes the Battery Easier to Live With#
High-capacity power banks are frustrating when they take forever to refill. The 737 avoids that trap with high-speed USB-C input, so the pack itself can recharge much faster than older battery banks that crawl back to full over several hours.
That is one of those features that affects long-term satisfaction more than first impressions. A battery you can top up quickly is a battery you will actually keep ready.
Strong Fit for Modern Travel and Daily Carry Tech#
The 737 is especially good if your gear revolves around USB-C. Laptops, tablets, phones, wireless headphones, handheld consoles, compact monitors, and USB-powered accessories all fit naturally into its use case.
That broad compatibility makes it easy to justify the price. Instead of buying separate chargers for separate situations, you get one battery pack that covers commuting, travel, remote work, and backup power in a single piece of kit.
