Anker 737 power bank review
Premium power banks designed for high-wattage laptop charging are rare, but the Anker 737 stands out thanks to its 140W output, making it one of the best choices for MacBook Pros and other power-hungry laptops. Anker is a well-known brand recognized for quality, and the 737 delivers top-tier performance with a 24,000 mAh (86.4 Wh) capacity, a built-in screen, and multiple ports for a variety of devices.
While the 737 also comes with a premium price tag, at least it's easy to purchase – either directly from Anker, through online stores, or on Amazon. It's often discounted by up to 30% compared to the list price, making it a great deal for those who can catch it on sale. Plus, it's flight-safe, making it perfect for travelers who need a reliable power source for tedious long-haul flights.
The Anker 737 is one of a small number of power banks that cater to the latest high-end laptops, with the ability to supply up to 140W (28V, 5A) from the main USB-C port. Of course, it also handles charging phones or other portable devices just as well, with the second USB-C port offering up to 100W (20V, 5A) output, while the USB-A delivers 18W (9V, 2A). The 737 supports fast charging a phone at up to 27W (9V, 3A) as well as PPS 5A (3.3V – 21V) for wide compatibility, including Samsung fast charging.
At 630 grams, the Anker 737 is heavier than some alternatives, but its square 15.7 × 5.5 × 5 cm form factor is particularly well-suited for placement in drink bottle holders and is easy to pack in most bags, though it may be a tight fit in slim laptop bags. The power bank features an excellent color screen that provides real-time information on remaining capacity, battery health, and power output from each port, making it a valuable tool for monitoring device charging. It also includes a low-current charging mode for smaller accessories, activated by double pressing the power button.
The Anker 737’s standout feature is its ability to sustain a 140W output with rock-steady voltages. While it does get warm under sustained high-wattage loads, efficiency remains solid. The Gen 1 model I tested doesn't support 12V output from the USB-C ports, but the latest Gen 2 version of the Anker 737 is upgraded with 12V/3A PD-spec output that, among other things, charges DJI drone batteries at full speed.
At 140W (28V, 5A), 85% of the rated capacity is available. At a more common 100W (20V, 5A), an excellent 89% of the rated capacity is maintained. For phone charging at 9V 20W, the efficiency remains high at 87%. USB-C charging is the most efficient, while the USB-A port delivers 70.5 Wh (81.5%) at 5V 2A compared to 74.2 Wh (86%) from USB-C.
The Anker 737 charges itself impressively fast, reaching full capacity at 140W in under an hour. At 100W, it takes approximately 1.5 hours. It supports pass-through charging at up to 90W, but doesn't allow self-charging at the same time and lacks a UPS mode. The power bank uses high-quality 21700 cells and actively monitors battery health, making it an excellent choice for heavy daily use.

How I test power banks
I get hands-on with every power bank I test and conduct extensive evaluations in both lab and real-world scenarios. Using tools like the ChargerLab POWER-Z KM003C, I measure charge voltage, protocol support, and log capacity tests.
Each power bank is also tested with real devices, including phones, tablets, and laptops, and connected to a programmable load tester for multiple charge cycles. I carry a selection daily in both pockets and bags to assess their durability and ability to withstand everyday use.
All measurements and weights are personally verified, ensuring accuracy beyond the manufacturer’s listings.
