In a world where our laptops, tablets, and phones are the engines of our productivity and creativity, running out of battery isn’t just an inconvenience—it’s a showstopper. For digital nomads, busy professionals, and tech enthusiasts, the search for a portable power solution that can keep up with high-demand devices is constant. The Anker 737 Power Bank (PowerCore 24K) enters the scene not just as another battery pack, but as a robust powerhouse designed to meet the needs of the most energy-hungry tech. With a massive 24,000mAh capacity and a groundbreaking 140W output, this device promises to be the ultimate charging companion. But does it live up to the hype?
What Sets the Anker 737 Apart from the Pack?
The defining feature of the Anker 737 Power Bank is its sheer power. Equipped with the latest Power Delivery 3.1 technology, it delivers a massive 140W charge through its USB-C ports. This isn’t just fast—it’s revolutionary for a portable charger, allowing it to power and rapidly charge high-performance laptops like the 16-inch MacBook Pro, which was previously a challenge for portable batteries.

This impressive performance is matched by its bi-directional charging capability. The same 140W input allows the PowerCore 24K to recharge itself in under an hour when paired with a compatible high-speed wall charger. This dramatically reduces downtime, ensuring your power bank is ready to go when you are.

Design and Build: Premium and Practical
From the moment you hold the Anker 737, its premium build quality is evident. It’s solid, hefty, and feels like a serious piece of equipment. The matte black finish and textured, grippy sides give it a professional look while ensuring it doesn’t easily slip from your hand.
While it’s too bulky to be considered a pocket-friendly device, its elongated, brick-like shape is designed for stability and fits neatly into a backpack or laptop bag. The weight is a necessary trade-off for its immense capacity and power output, a compromise that professionals who need reliable power will find acceptable.
“The Anker 737 isn’t trying to be the smallest power bank on the shelf,” notes tech expert Sarah Jenkins. “It’s engineered for performance. Its purpose is to provide desktop-level charging power in a portable form factor, and its design reflects that mission—it’s robust, stable, and built to last.”
The Smart Digital Display: Information at Your Fingertips
One of the most praised features of the Anker 737 Power Bank PowerCore 24K is its smart digital display. This small color screen is a game-changer, providing real-time data that eliminates the guesswork common with other power banks.
The display shows:
- Battery Percentage: The remaining capacity at a glance.
- Input/Output Wattage: See exactly how much power is flowing into the power bank or out to your devices from each port.
- Time to Full/Empty: An estimate of how long it will take to recharge the power bank or how long it can continue charging your devices at the current rate.
- Battery Health: Monitor the long-term condition of the internal cells.
This level of transparency is incredibly useful for managing power on the go, allowing you to see if your devices are charging at their optimal speed and to plan your recharges effectively.
Real-World Performance: Speed and Capacity Tested
On paper, the specs are impressive, but how does the Anker 737 perform in the real world? It delivers. In testing, it can take a 16-inch MacBook Pro from 0 to 50% in about 40 minutes, all while the laptop is in use. This is on par with the performance of a native wall charger.
The 24,000mAh capacity provides substantial power reserves. You can expect to get nearly five full charges for an iPhone 13, over one full charge for a 12.9-inch iPad Pro, or a significant boost to most USB-C laptops, often extending their runtime by several hours. The three-port design also offers excellent flexibility, allowing you to charge a laptop, a tablet, and a phone simultaneously.
Is the Anker 737 Power Bank the Right Choice for You?
While the PowerCore 24K is a top-tier device, it may not be for everyone. Here’s a breakdown to help you decide.
