Anker 737 Power Bank A1289, 140W 24,000mAh Portable Charger with 3 Ports

At 6.13 × 2.14 × 1.95 inches, the Anker 737 Power Bank packs 24,000mAh into a portable format for charging away from an outlet. Its 140W Power Delivery 3.1 output supports compatible laptops as well as phones. Three ports let you connect multiple devices, and the smart display makes charging information easy to check.

What you’ll notice day to day

The 24,000mAh capacity is suited to long days away from a desk, travel, or keeping devices ready between outlets. With two USB-C ports and one USB-A port, you can charge a compatible laptop, phone, or other device without relying on a single connection. The maximum total output is 140W, with up to 140W from one port, actual charging power depends on the connected device and its input limit.

The digital display shows real-time input and output power and estimates recharge time. That gives you a quick way to see what the bank is doing while charging, rather than relying only on a status light. Customers often appreciate the power capacity, portability, and display. Feedback on charging speed and battery life is mixed, and some find the unit heavier than expected, so its 21 oz weight is worth factoring into how you plan to carry it.

What matters most

This model is built to serve more than a phone-only charging role. Its 140W capability makes it useful for compatible laptops on a commute, during travel, or while working away from an outlet, while the additional ports let you connect a phone or another device at the same time. For shoppers comparing a compact, phone-focused bank with a higher-output option, the Anker 737’s laptop charging support and three-port layout are the distinguishing features.

The smart display adds practical visibility, while the 24,000mAh capacity gives you a substantial reserve for days with several devices in use. It is compatible with laptops and phones, including listed MacBook, Dell, iPhone, and Samsung devices. For the fastest charging the setup supports, use a 5A cable and a 140W charger when recharging the bank, connected devices also determine their own charging speed, which can decrease as their batteries fill. A 60W cable, for example, limits charging to 60W.

Practical tips

For everyday use, check the display to monitor input, output, and estimated recharge time. Charging can produce warmth, particularly when a connected phone is being used for gaming or video streaming. If the power bank or device feels warm, charge in a cool, well-ventilated place and pause use of devices that are charging. The product is designed to meet airline carry-on requirements, making its portable format useful for keeping compatible devices powered during air travel.

When it makes sense

A solid pick if you want one rechargeable bank for a laptop and personal devices rather than a phone-only backup. The combination of 24,000mAh capacity, up to 140W output, three charging ports, and an informative display suits travel days and mobile work when you need to power more than one compatible device. Its strongest appeal is having laptop-level charging capability and useful status information in a single portable unit.
