Anker 737 Power Bank PowerCore 24K puts a 24000mAh battery and up to 140W USB-C output into a handheld charger for laptops, tablets, and phones, giving US travelers and commuters a way to keep multiple devices powered without hunting for an outlet.
Capacity, Ports, And Power Delivery
Anker 737 Power Bank PowerCore 24K uses a 24000mAh cell rated at 86.4Wh, paired with two USB-C ports and one USB-A port for a total of three outputs in a compact housing.The manufacturer lists 24000mAh capacity, 86.4Wh energy, and three ports.
The two USB-C ports each support USB Power Delivery 3.1 with output modes of 5V 3A, 9V 3A, 15V 3A, 20V 5A, and 28V 5A, with a maximum of 140W available across the ports, while the USB-A port offers 5V 3A, 9V 2A, or 12V 1.5A up to 18W.A technical overview confirms the PD 3.1 support and 140W USB-C output with 18W USB-A output.
When only one USB-C port is used, Anker 737 Power Bank PowerCore 24K can deliver up to 140W to a compatible laptop, while combinations of USB-C and USB-A share the total 140W output using internal power management so phones, tablets, and notebooks can be charged at the same time.Retail specifications detail one-port, two-port, and three-port power distribution up to 140W total.
Design, Size, And Display
Anker 737 Power Bank PowerCore 24K measures about 6.13 inches long, 2.15 inches wide, and 1.95 inches thick, giving it a brick-like shape that fits into a laptop bag or carry-on while still leaving room for cables and accessories.The manufacturer lists dimensions of 6.13 x 2.15 x 1.95 inches for this model.
The power bank uses an outer shell with rounded edges and places its two USB-C ports and one USB-A port on one end, while a digital display on the side shows remaining battery percentage, estimated time to full when recharging, and active output power level during charging sessions.An independent review notes the 86.4Wh battery and the integrated digital display for live power information.
The overall footprint and weight place Anker 737 Power Bank PowerCore 24K in the heavy-duty portable charger segment rather than pocket chargers, which matches its role as a companion for USB-C laptops, large tablets, and multiple phones instead of a single-phone day charger.
Full Specifications For Anker 737 Power Bank PowerCore 24K
Anker publishes detailed specs, power distribution tables, and compatibility notes for Anker 737 Power Bank PowerCore 24K on its product page.
Charging Performance And Two-Way Fast Charging
Anker 737 Power Bank PowerCore 24K supports up to 140W two-way fast charging, meaning the battery itself can be recharged at high power through USB-C as well as deliver up to 140W out, which shortens both refill times and laptop charging sessions compared with older 45W or 60W portable chargers.The spec sheet highlights 140W two-way PD 3.1 charging through USB-C.
Internal power management circuitry uses Anker PIQ 3.0 and PD 3.1 to negotiate with connected devices, so laptops that support 140W USB-C input can draw close to full charger power, while phones and tablets negotiate lower power modes that match their own charging limits.The technical description notes PIQ 3.0 support along with PD 3.1 and PPS for phones, tablets, and laptops.
The power bank can charge typical smartphones several times over and can provide substantial runtime extensions for USB-C laptops, with third-party measurements describing usable energy of roughly three-quarters of the rated 86.4Wh when running at high power levels, which is in line with conversion and heat losses in this class of devices.An external spec overview reports 24000mAh capacity, 86.4Wh energy, and a 140W max output.
Compatibility With Laptops, Tablets, And Phones
Anker 737 Power Bank PowerCore 24K is positioned as a laptop-class portable charger and supports a wide list of USB-C devices, including MacBook Air models, USB-C charging notebooks that accept up to 140W input, iPad Pro, and recent iPhone and Samsung Galaxy phones that support fast charging over USB-C or USB-A.Anker lists compatibility spanning iPhone 8 through 14, Samsung S22 and S23 series, Google Pixel 6 and 7, MacBook Air M2, and various iPad models.
Because Anker 737 Power Bank PowerCore 24K uses standard USB-C PD 3.1 and PPS profiles, it works with many USB-C laptops that draw 100W or more during heavy use as well as phones that request 20W, 30W, or similar fast-charge levels, and its USB-A port maintains support for older cables and devices that still rely on USB-A connectors.
The three-output design allows combinations such as powering one laptop from USB-C1 while charging a phone from USB-C2 and topping up wireless earbuds from USB-A, with internal limits ensuring that the total output stays within the rated 140W during multi-device use.A retailer spec table breaks down one-port, two-port, and three-port distribution, including 140W USB-C only and 118W plus 18W splits.
Price And Value In The High-Power Segment
In the US market, Anker 737 Power Bank PowerCore 24K appears around $109.99 at recent list pricing, placing it above many compact phone-only power banks but in line with other laptop-capable portable chargers with similar capacities.A technical and price overview reports a $109.99 price for Anker 737 Power Bank PowerCore 24K.
For buyers who want a charger primarily for phones, smaller Anker models with lower capacity and lower maximum output often cost less and weigh less, but they typically offer 20W to 45W output and are not intended to run power-hungry USB-C laptops.
Seen against those alternatives, Anker 737 Power Bank PowerCore 24K targets users who routinely carry a laptop, work on the road, or run high-power tablets, and who need a portable charger that can provide close to wall-adapter power levels while still fitting into travel bags and backpacks.
Comparison With Anker 733 Power Bank And Typical Chargers
Anker itself contrasts Anker 737 Power Bank PowerCore 24K with Anker 733 Power Bank, which combines a lower-capacity battery with a wall charger, highlighting the 737 model's focus on maximum portable capacity and power for laptops rather than combo wall-and-battery convenience.A manufacturer blog explains the 24000mAh capacity and 140W output of Anker 737 versus the more compact Anker 733.
Where many standard power banks in the phone-focused segment offer 10000mAh to 20000mAh capacity and peak outputs around 18W to 45W, Anker 737 Power Bank PowerCore 24K almost doubles the capacity of common compact units and triples or more the peak power output, which shifts it into a different category of use that includes powering USB-C notebooks and larger tablets during flights or remote work.
Compared with lightweight pocket chargers, the trade-offs are higher weight and a larger footprint, but in return users gain the ability to connect multiple high-drain devices and see detailed status information on the built-in display, making Anker 737 Power Bank PowerCore 24K suited for intensive digital workloads away from fixed power sources.
Positioning And Use Cases
Anker 737 Power Bank PowerCore 24K fits into the high-power portable charger segment, aimed at people who carry USB-C laptops, work tablets, and modern phones and who need sustained power while traveling by air, rail, or car without reliable access to wall outlets.
Its combination of 24000mAh capacity, 140W PD 3.1 two-way charging, three output ports, and a digital display make it suitable for creators, business travelers, and students who rely on USB-C notebooks, as well as gamers who run handheld consoles or gaming laptops that demand higher power levels than older portable chargers can deliver.
The main limits are its size and weight compared with smaller pocket units, so it serves best as a primary external battery for laptop-plus-phone setups rather than an everyday single-phone backup, and buyers who want maximum mobility with minimal bulk may still opt for compact, lower-capacity chargers while using Anker 737 Power Bank PowerCore 24K for longer trips and work-intensive days.
