Overview
The Anker 737 Power Bank, also known as the PowerCore 24K, positions itself as a premium solution in the portable charging market. It's not just for topping up your phone; this power bank is built for the high-demand needs of modern mobile computing. Featuring a very large 24,000mAh capacity and the latest in charging technology with 140W Power Delivery 3.1, the Anker 737 is designed to be a single charging source for your entire tech arsenal, including power-hungry laptops.
Key Features
The Anker 737 Power Bank isn't just about its large capacity. It packs several standout features that cater to power users and tech enthusiasts who need reliable, fast, and intelligent charging on the go.
140W Bi-Directional Fast Charging
The headline feature is its support for USB Power Delivery 3.1, enabling a massive 140W of power transfer. This is "bi-directional," which means not only can the power bank deliver 140W to a compatible device (such as a 16-inch MacBook Pro), but it can also be recharged at the same blistering speed. This dramatically reduces downtime. Recharging a 24,000mAh battery can be a lengthy process, but with a 140W wall adapter (sold separately), the Anker 737 can be refueled significantly faster than its competitors.
To take full advantage of the 140W recharging speed, pair the Anker 737 with a 140W or higher Power Delivery wall adapter. A lower-wattage charger will still work, but will refuel the power bank more slowly.
Intelligent Digital Display
Moving beyond the simple four-LED indicators of the past, the Anker 737 includes a full-color smart digital display. This screen provides at-a-glance, real-time information that power users will appreciate. It shows the current battery percentage, the power draw (in watts) for each connected device, and the estimated time until the power bank is fully charged or fully depleted at the current rate. This level of detail allows for precise power management and removes the guesswork typically associated with portable batteries.
High Capacity and Multi-Device Support
With a total capacity of 24,000mAh, the Anker 737 holds a significant amount of energy. This is enough to charge a modern smartphone multiple times or provide nearly a full charge for many high-end laptops. It features three ports to share this power: two versatile USB-C ports and one legacy USB-A port. This allows it to charge up to three devices simultaneously, making it an ideal companion for travelers or anyone juggling a phone, laptop, and another accessory like headphones or a tablet.
While the total output is 140W, this power is shared when multiple ports are in use. The power bank intelligently distributes the wattage, but a single port will not maintain its maximum output if other devices are also drawing power.
Design & Build
The Anker 737 Power Bank has a functional, utilitarian design. It comes in a sleek Black finish and has a rectangular prism shape. Given its high capacity and power output, the dimensions of 6.13 x 2.15 x 1.95 inches are reasonably compact, making it suitable for stowing in a backpack, laptop bag, or carry-on luggage. The smart display is located on the front face for easy viewing, with the three charging ports situated on one of the end caps for accessible cable management.
With a capacity of 24,000mAh (approximately 88.8Wh), the Anker 737 Power Bank is compliant with FAA regulations (under the 100Wh limit) and is suitable for carry-on luggage on most airlines. However, it's always a good idea to double-check with your airline before flying.
Who It's For
This power bank is clearly aimed at individuals with high-performance charging needs. Digital nomads, business travelers, and students who rely on powerful laptops that support USB-C Power Delivery will find the 140W output particularly valuable, as it allows them to work and charge without being tethered to a wall outlet. The massive capacity and three-port layout also make it a great choice for trips, where a single charging solution can service an entire family's or individual's collection of gadgets—from phones and tablets to headphones and portable gaming consoles.
Conversely, users who only need to top up a single smartphone might find the Anker 737 to be overkill. Its size, cost, and advanced feature set are best leveraged by those who can make use of its high-wattage charging capabilities.
