Safety: Power banks contain lithium-ion cells. Use the cables the manufacturer supplies or recommends, keep the unit away from heat, and follow the manual.
The Anker 737 Power Bank is a 24,000mAh bank that lists 140W output over USB Power Delivery 3.1, aimed at people whose laptop charger is rated above 100W. It adds a smart display that shows output and input power and an estimated recharge time, and it ships with a 140W USB-C cable.
This review is based on the manufacturer listing and specifications. It is meant for travelers and remote workers deciding whether a high-wattage bank is worth carrying. See more options in our Laptop Power Banks category.
Our Verdict
The strongest point of the Anker 737 Power Bank is that it pairs 140W Power Delivery 3.1 output with the matching cable in the box, so a high-wattage laptop can charge without a second accessory. The display is a practical extra because it reports input and output power and an estimated recharge time.
The main trade-off is that the listing leaves some details open: the combined output across ports and the port types are not stated in the product details. It suits a traveler with a large laptop charger; if your laptop charges at a lower wattage, a less powerful bank will do the same job.

Capacity and Output
The listing gives 24,000mAh of capacity and 140W of Power Delivery 3.1 charging, described as two-way, meaning the bank can also be recharged at high power. It notes that full 140W use needs a 5A cable and a 140W charger.
The listing does not give a combined output for all three ports, so we cannot state how power is shared when several devices are connected. Check the product page before relying on it for a laptop plus other devices.
Charging and Setup
The box includes a 140W USB-C to USB-C cable, a travel pouch and a welcome guide. Using the supplied cable matters because a cable rated for less power limits charging speed regardless of the bank.
The display provides real-time information on output and input power and an estimated recharge time. The listing does not give a recharge time of its own, so use the display or the manual for guidance.
Build, Size and Portability
The listed dimensions are 6.13 x 2.14 x 1.95 inches and the weight is 1.39 pounds, which the listing rounds to about 22 ounces. The thickness of nearly two inches makes it more of a bag item than a pocket item.
Anker states that the bank meets airline carry-on requirements. Airline rules depend on the rating printed on the unit, so confirm it and your airline policy before you fly. The listing gives a 24-month warranty.
Features and Compatibility
The listing names iPhone 16, 15 and 14 series phones, Vision Pro, Samsung devices and MacBook among compatible examples. It does not list every supported laptop, so compare your laptop charger rating with the 140W figure.
The bank can charge a phone and a laptop together, but the share each receives depends on the combined output, which the listing does not state.

Final Verdict
The Anker 737 Power Bank offers 140W output, a useful display and the matching cable for a high-wattage laptop, with a 24-month warranty. Its compromise is a thick body and a listing that does not state the combined output. Confirm your laptop charger rating and the missing details on the product page before you buy.
