In an era where our lives are increasingly powered by and dependent on mobile devices, a reliable power bank has shifted from a luxury to an absolute necessity. The market is flooded with options, ranging from cheap, questionable units to premium, high-capacity beasts. Navigating this landscape to find genuine value for money—a product that delivers exceptional performance and durability for its price—is a challenge. The Anker 737 Power Bank (PowerCore 24K) consistently emerges as a top contender in this category. This review delves into its features, strengths, weaknesses, and real-world performance to determine if it truly lives up to its value-oriented reputation.

Product Overview and Key Features

The Anker 737 is a high-capacity portable charger designed for the power-hungry user. It’s not the smallest or lightest device, but its feature set is engineered to justify its footprint.Massive 24,000mAh Capacity: This is the core of its appeal. With a rated capacity of 24,000mAh (approximately 88Wh), it falls just under the FAA's 100Wh limit for carry-on airline travel. This capacity translates to multiple full charges for most smartphones, several charges for tablets, and even the ability to power or extend the life of smaller laptops.Robust 140W Output: The 737 supports Anker’s proprietary Power Delivery 3.1 protocol. This allows for blistering fast charging speeds. It can charge a compatible MacBook Pro at full speed, and when using the two USB-C ports and one USB-A port simultaneously, it can deliver up to 140W of total output, with 100W available from a single USB-C port.Smart Digital Display: A standout feature is the integrated LCD screen. This doesn't just show crude battery percentages; it provides real-time data on the remaining battery percentage, current input and output wattage, and even the estimated time remaining until full discharge or recharge. This transparency is a significant value-add.Multi-Device Charging: Equipped with two USB-C ports and one USB-A port, it can charge three devices at once without a significant drop in efficiency, making it ideal for families, professionals with multiple gadgets, or travel companions.

The Advantages: Where the Value Shines

The value proposition of the Anker 737 is built on several key advantages that justify its price point.

1. True All-in-One Power Solution: For a user with a smartphone, tablet, and laptop, the 737 can effectively replace all individual chargers for short trips. The ability to fast-charge a laptop is a game-changer that many competing power banks in this price range cannot match. This consolidation eliminates the need to carry multiple accessories, offering immense practical value. 2. Unmatched Charging Speed and Efficiency: The 140W output is not a gimmick. In testing, it charged a 16-inch MacBook Pro from 10% to 50% in under 30 minutes. Similarly, modern smartphones like the Samsung Galaxy S23 Ultra saw a charge from 20% to 80% in roughly 35 minutes. This efficiency saves valuable time, a commodity often more precious than money itself. 3. The Clarity of the Display: The digital display moves beyond guesswork. Knowing exactly how much power is left and how much is being drawn by a connected device allows for intelligent power management. You can confidently plan your day without the anxiety of your power bank dying unexpectedly. 4. Build Quality and Reliability: Anker is known for its build quality, and the 737 is no exception. It has a solid, weighty feel that inspires confidence. Coupled with Anker’s reliable safety features like surge protection and temperature control, it feels like a durable product built to last, avoiding the planned obsolescence of cheaper models.

The Drawbacks: Considerations for the Buyer

Despite its strengths, the 737 has some inherent trade-offs that are crucial for a balanced assessment.

1. Size and Weight: This is the most significant compromise. Weighing in at just over 1.5 pounds (approx. 700g) and with a substantial footprint, it is not a device you casually slip into a pants pocket. It is designed for a backpack, briefcase, or carry-on luggage, not for light, everyday carry. 2. The Included Cable, But No Wall Charger: Anker includes a high-quality 140W USB-C to USB-C cable, which is excellent. However, to achieve the advertised 130W input recharge speed, you need to provide your own compatible high-wattage wall charger. Using a standard phone charger will result in a very long, multi-hour recharge time, which can be inconvenient. 3. Premium Price Point: While it offers great value, it is not a "cheap" product. It sits at a premium price point within the power bank market. The value is derived from its performance and feature set, but the initial investment is higher than that of a basic 10,000mAh power bank.

Actual Usage Experience

In daily use, the Anker 737 performs exactly as advertised. For a freelance photographer on a shoot, it was able to keep a laptop, mirrorless camera, and phone powered throughout a full day of work, something previously requiring two separate power banks. The display was constantly checked and proved to be accurate, eliminating all battery anxiety.

On a weekend trip, it served as a shared power hub for two people, easily keeping two phones and a pair of wireless earbuds topped up without ever needing to hunt for a wall outlet. The three-port design proved its worth. The only noticeable hassle was its weight in a small sling bag and the long overnight recharge time when using a standard 20W iPhone charger.

Conclusion: The Verdict on Value

The Anker 737 Power Bank is a masterclass in targeted value engineering. It does not attempt to be the smallest or the cheapest. Instead, it focuses on being the most powerful, informative, and reliable portable power solution for its specific price segment.

Its value for money is not universal; it is exceptional for a specific user. If you are a digital nomad, a professional with multiple high-wattage devices, a frequent traveler, or simply someone who despises battery anxiety and wants a single, robust solution, the Anker 737 is an outstanding investment. The combination of massive capacity, blistering speed, intelligent display, and solid build quality justifies its cost over the long term.

However, if your needs are limited to occasionally topping up a single smartphone while on the go, its size, weight, and cost would represent poor value. For that user, a smaller, less expensive model would be more appropriate. Ultimately, the Anker 737 earns its "value for money" badge by delivering a premium, feature-complete experience that efficiently solves a specific set of power problems for its target audience, making it worth every penny for those who need what it offers.
