Anker 737 Electric Power Bank Review
Quality power banks designed for charging high-power laptops are rare, but Anker The 737 is eye-catching due to its 140W output, which is one of the best choices for MacBook Pros and other laptops that are eager to rush. Anker is a well-known brand recognized for quality, while the 737 has 24,000 mAh (86.4 WH) capacity, built-in screen and multiple ports for multiple devices.
While the 737 also comes with a premium price tag, it is at least easy to buy – directly from Anker, via the online store or On Amazon. It usually offers up to 30% off compared to the list price, which is a lot for those who can sell. Plus, it is flight-safe and is perfect for travelers who need reliable cumbersome long-haul flights.
The Anker 737 is one of the small power banks that cater to the latest high-end laptops, capable of delivering up to 140W (28V, 5A) from the main USB-C port. Of course, it can also handle charging phones or other portable devices, with the second USB-C port providing output up to 100W (20V, 5A) while the USB-A offers 18W (9V, 2A). 737 supports fast charging with up to 27W (9V, 3A) as well as PPS 5A (3.3V – 21V) for wide compatibility, including Samsung Fast charging.
The Anker 737 is 630g away, which is heavier than some alternatives, but its square 15.7×5.5×5 cm form factor is especially suitable for placement in a beverage bottle rack and is easy to pack in most bags, although it may be perfect for Slim Laptop bags. This power library has an excellent color screen that provides real-time information about remaining capacity, battery health and power outputs per port, making it a valuable tool for monitoring device charging. It also includes a low current charging mode for smaller accessories and is activated by double pressing the power button.
The Anker 737’s outstanding feature is its ability to output a rocky voltage of 140W. Although it does become warm under continuous high combat loads, efficiency remains stable. The Gen 1 model I tested does not support 12V output on USB-C ports, but the latest Gen 2 version Anker 737 upgrades the 12V/3A PD-SPEC output, among other things, DJI Drone battery at full speed.
At 140W (28V, 5A), 85% of the rated capacity is available. On the more common 100W (20V, 5A), 89% of the rated capacity is maintained. For 9V 20W phone charging, the efficiency remains high at 87%. USB-C charging is the most effective, while the USB-A port offers 70.5 WH (81.5%) at 5V 2A, while USB-C’s 74.2 WH (86%).
The Anker 737 charges impressively, reaching full capacity of 140W in an hour. At 100W, it takes about 1.5 hours. It supports traffic charging up to 90W, but does not allow automatic charging at the same time and lacks UPS mode. Power Bank uses high-quality 21,700 batteries and actively monitors the health of the battery, which is an excellent choice for a large number of daily use.

How do I test the electric bank
I can practice it on every power bank I tested and have extensive evaluations in the lab and in the real world. Using tools like Chargerlab Power-Z KM003C, I measure charge voltage, protocol support and log capacity testing.
Each power library is also tested with real devices, including phones, tablets and laptops, and is connected to multiple charge cycles of the programmable load tester. I choose on my pockets and bags every day to evaluate its durability and ability to withstand everyday use.
All measurements and weights are personally verified to ensure accuracy beyond the manufacturer’s list.
