'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.

Power banks are a really handy, portable way to keep your smartphones, laptops and other devices charged up. But the latest MacBook Pro needs 140W of power to fast-charge, which is more than most power banks can handle.
The Anker 737 power bank changes this. This power bank can output a full 140W of power needed to handle the most demanding workloads.
The Anker 737 has a very solid, brick-shaped construction, of exactly the sort of high quality that I have come to expect from a company like Anker. It has a battery capacity of 24,000 mAh, good for nearly five recharges of an iPhone 13, and more than one charge of the MacBook Pro.
On one end are three USB ports (two USB-C, one USB-A), and there's also a small but bright and readable color display. On the side is a button that controls everything.
On the display you can see information on battery capacity, charge and discharge currents from the various ports, the time needed to recharge or discharge, temperature, battery health, and other info.
This offers a great overview of the overall health of the power bank, as well as the power that's going into and out of it.
As for power output, the three ports are capable of outputting 140W of power, depending on the configuration:
Single USB-C in use: Up to 140W
Two USB-C ports in use: Up to 140W
One USB-C and one USB-A in use: Up to 100W for both USB-C, up to 18W for USB-A
Two USB-C and one USB-A in use: Up to 122W for both USB-C, up to 18W for USB-A
There's also a trickle-charge feature for low-draw devices such as earbuds and the like. This is activated by double-pressing the button.
Inside are all the safety features you'd expect from a quality power bank, such as temperature sensing and over/under voltage protection.
As for charging, I managed to get the power bank to take in power at close to 130W using the Apple MacBook Pro 140W charger and the supplied cable.
Anker says the supplied cable is rated for 140W, so it's a good idea to keep this handy for fast-charging if you have a 140W charger.
The Anker 737 is now my favorite power bank. The 140W output is a massive game-changer for keeping my MacBook Pro charged up when I'm out and about. The bright, crisp display adds value rather than being a gimmick, and the addition of a USB-A port along with the USB-C ports means that legacy devices don't get left out in the cold.
