Anker 737 Power Bank 24000mAh Review

In an era where our daily carry includes power-hungry laptops, smartphones, and tablets, the Anker 737 Power Bank 24000mAh emerges as a formidable off-grid energy solution. Boasting a massive capacity and incredibly fast 140W bidirectional charging, this power brick is designed to keep your entire tech ecosystem running. We put this premium portable charger to the test to see if it lives up to its heavyweight reputation.

Key Specifications

Design & Build Quality

When you first unbox the Anker 737, its dense, premium feel is immediately apparent. Moving away from the traditional flat, slab-like designs of older power banks, Anker has opted for a chunky, rectangular prism aesthetic that stands upright on your desk. Wrapped in a matte black, soft-touch polycarbonate shell with textured silver accents, it looks exactly like the high-end piece of tech it is, resisting fingerprints reasonably well while offering a secure, tactile grip.

However, that density translates to significant heft. Weighing in at 1.39 pounds (630 grams), the Anker 737 is not the kind of battery pack you slip unnoticed into your pocket. It is undeniably a backpack companion, engineered for digital nomads, photographers, and professionals who need severe backup power on the go. Despite the bulk, the rounded edges and seamless construction make it surprisingly ergonomic to handle when transferring it between your travel bag and a workspace.

Performance

The true marvel of the Anker 737 lies in its raw output capabilities. Equipped with Power Delivery 3.1 (PD 3.1), this power bank can deliver a staggering 140W of maximum output through a single USB-C port. In our real-world 2026 benchmarking, it easily charged a 16-inch MacBook Pro from 0% to 50% in just under 40 minutes. Even when pushing power to a laptop, a smartphone, and wireless earbuds simultaneously across its three ports, it expertly balanced the wattage without a hitch.

Efficiency and thermal management are also top-tier. Thanks to Anker’s proprietary ActiveShield 2.0 technology, the internal temperatures remained well within safe operational limits even during sustained 140W discharging. Furthermore, the 24,000mAh (86.4Wh) capacity is a strategic sweet spot: it falls neatly under the TSA’s 100Wh flight restriction, meaning you can legally carry this powerhouse onto commercial airlines without raising any red flags with airport security.

Bidirectional charging ensures that downtime is kept to an absolute minimum. When connected to a compatible 140W wall adapter, the Anker 737 can recharge from flat to 100% in a blistering 52 minutes. For a battery of this magnitude, skipping the agonizing overnight charging routine is an absolute game-changer for frequent travelers who only have brief layovers near an AC outlet.

Features & Software

What elevates the Anker 737 from a mere battery to a smart gadget is its integrated smart color digital display. A press of the side button illuminates a crisp, high-contrast screen that provides a wealth of real-time data. It shows the overall battery percentage, estimated time until fully recharged (or discharged), and a live breakdown of the wattage going in and out of each individual port.

This onboard software interface eliminates the guesswork usually associated with portable chargers. You know exactly if your device is fast-charging, and the inclusion of an auto-rotation feature ensures the display is always readable, regardless of how the power bank is positioned on your desk. Additionally, a secondary menu screen lets you monitor the total cycle count and battery health, ensuring you have clear visibility into the long-term degradation of the internal lithium-ion cells.

Value Proposition

The Anker 737 Power Bank is explicitly positioned as a premium peripheral, and its price tag reflects that flagship status. For the casual user who simply needs to top up a smartphone on a weekend trip, the high cost of entry is likely overkill. However, for power users who rely on high-drain laptops, portable gaming consoles, or multiple mobile devices while off the grid, the investment quickly pays for itself in sheer utility and time saved.

When you factor in the PD 3.1 140W output, the incredibly fast recharge time, and the informative smart display, the Anker 737 offers exceptional value within the high-performance tier. It effectively replaces the need for carrying multiple weaker power banks, streamlining your everyday carry into one highly capable, reliable unit that is future-proofed for the next generation of fast-charging tech.

How It Compares

When standing toe-to-toe with the UGREEN 145W Power Bank, the Anker 737 holds a distinct advantage with its highly informative digital display and faster dedicated single-port output (140W vs UGREEN’s 100W maximum on a single port). While the UGREEN model offers slightly more capacity at 25,000mAh, Anker’s superior user interface and rapid bidirectional recharge capabilities make it the more sophisticated choice for tech enthusiasts. Against the popular Shargeek Storm 2, the Anker 737 opts for a professional, subdued aesthetic compared to the Shargeek’s transparent cyberpunk design, while providing a higher wattage output and a more rugged build quality at a generally more competitive price point.

Pros and Cons
