Anker 737 Power Bank Review: More Than Just a Battery

In a world saturated with portable chargers, it takes something special to stand out. Most power banks are simple, utilitarian bricks designed to do one job: slowly top up your phone. But as our devices become more power-hungry—from 16-inch laptops to high-end tablets and professional cameras—the humble power bank has struggled to keep up. Enter the Anker 737 Power Bank (also known as the PowerCore 24K), a device that isn’t just a bigger battery, but a smarter, faster, and fundamentally more ambitious take on portable power. It aims to be the single charging solution for your entire tech arsenal, and for the most part, it succeeds brilliantly.
Performance: 140 Watts of Uncompromising Power

The headline feature of the Anker 737 is its staggering 140W maximum output from a single USB-C port. This isn’t just a number on a spec sheet; it’s a paradigm shift for portable charging. For years, charging a high-performance laptop like a MacBook Pro 16″ with a power bank was a losing battle—you could slow the discharge, but rarely charge it effectively while under heavy load. The 737 obliterates that limitation. It delivers enough power to fast-charge not only a MacBook Pro but also Dell XPS models, Razer Blades, and other power-hungry USB-C laptops, often matching the speed of their included wall adapters.

With a 24,000mAh (86.4Wh) capacity, it sits just under the 100Wh TSA flight limit, making it a perfect travel companion. In real-world terms, this capacity can provide approximately one full charge for a 13-inch MacBook Pro, or around 4-5 full charges for an iPhone 14 Pro. The power bank also supports bi-directional charging, meaning the same USB-C port used for its blistering output can also be used to recharge the bank itself at up to 140W. Paired with a compatible GaN charger, the entire 24,000mAh cell can be refilled from empty in less than an hour, a monumental improvement over the overnight charging times of its predecessors.
Design and The Genius Display
At first glance, the 737 is unmistakably an Anker product. It’s a dense, vertical slab with a premium feel, featuring a textured, grippy front and a smooth, semi-matte finish on the back. However, it is by no means a pocketable device. Weighing in at 1.4 lbs (635g), it’s a deliberate addition to your backpack or gear bag, not your jacket pocket. This is a trade-off for its immense power, and one that its target audience of professionals and power users will likely accept.

What truly sets the 737 apart is its smart color display. Activated by a button on the side, this small screen is a game-changer that banishes charging guesswork. It provides a wealth of real-time data: the current input and output wattage for each of its three ports (two USB-C, one USB-A), the remaining battery percentage, the estimated time until full or empty, battery temperature, and even a battery health percentage. Knowing exactly how much power your laptop is drawing or how long you have until the bank is recharged transforms the user experience from passive to informed. It’s a feature you don’t know you need until you have it, and then you can’t live without it.
Value Proposition: An Investment in Freedom
There is no getting around the fact that the Anker 737 is an expensive piece of kit. It commands a significant premium over standard power banks. However, its value isn’t measured in cost-per-milliamp-hour. Its value lies in consolidation and capability. For a digital nomad, a traveling professional, or a student who works from various locations, the 737 can replace multiple smaller power banks and even the need to carry a dedicated laptop charging brick for short trips. The ability to work at full capacity from a coffee shop, an airport lounge, or a park bench without being tethered to a wall is a powerful form of freedom. When viewed as a professional tool that enables productivity in any location, the price becomes far more justifiable.
The Final Verdict
The Anker 737 Power Bank is not for everyone. If you just need a small battery to give your phone a boost at the end of the day, this is complete overkill. But if you’re a power user, a remote worker, a content creator, or a frequent traveler whose workflow depends on high-performance devices, the 737 is a masterpiece. It combines market-leading power output, a genuinely useful smart display, and a travel-friendly capacity into a single, robust package. It’s a premium product with a premium price, but it delivers an equally premium experience that solves a very real problem for the modern tech user. It’s less of a simple accessory and more of an essential piece of infrastructure for a mobile-first world.
