Build and Design

In terms of build quality, the Anker 737 Power Bank has a nice smooth finish, with a completely flush display on top. It isn’t too difficult to hold given its size, opting for a longer thin design versus more of a larger brick shape. The construction feels pretty sturdy, and our sample has taken a few drops without any ill effects. When it comes to weight, it does have some heft but that is expected given the large battery.

Anker makes the 737 Power Bank simple to use, which is most evident with its single button and basic OLED screen. The display provides real-time information about the output and input power, allowing you to monitor the charging progress. Additionally, it estimates the time required for the power bank to fully recharge or discharge, giving you a better sense of planning and managing your charging needs.

Under the advanced area, the screen will show you the number of charge cycles the battery has gone through, overall health, current temperature, and other useful power stats. You can also change if the screen goes to sleep on its own or stays on all the time if that is something you want to adjust. That also happens to be the only adjustment available on the battery.
