Anker 737 Power Bank: What to Know
The Anker 737 is the highest-capacity, highest-wattage unit in this group. Per the listing's own feature bullets, it carries a 24,000mAh battery and supports Power Delivery 3.1 with bi-directional charging - meaning the same 140W port can both fast-charge a connected laptop and recharge the bank itself. The listing explicitly notes that it does not support wireless recharge using a charging base, so this is a cable-only affair.
The digital display is the other headline feature. Per Anker's own description, it shows output and input power plus an estimated time for the bank to fully recharge - useful if you want to know whether you have enough left for one more laptop top-up before a flight.
On real-world capacity, the listing's own claim is that 24,000mAh will juice an iPhone 13 almost five times or a 2021 iPad Pro 12.9-inch about 1.3 times. Those are manufacturer figures, not our measurements, and they will vary with the device and cable you use. The box contents per the listing are the power bank itself, a welcome guide, and a 24-month warranty.
