Introduction
In our increasingly mobile and device-dependent world, the demand for reliable, high-speed portable power has never been greater. From laptops and tablets to smartphones and smartwatches, keeping all our gadgets charged on the go is a constant challenge. Traditional power banks often fall short when it comes to supporting power-hungry devices like modern laptops, or they sacrifice portability for capacity. Enter the Anker 737 Power Bank, a device that promises to bridge this gap with its impressive 140W GaNPrime output and substantial 24,000mAh capacity. This review delves into whether this powerhouse lives up to its reputation as a potential ultimate portable charger for your everyday technology.
Product Overview
The Anker 737 Power Bank, part of Anker’s GaNPrime series, is designed for users who require serious power delivery in a portable form factor. Boasting a robust 24,000mAh battery capacity, it’s capable of multiple recharges for most smartphones and can even provide significant charges for demanding laptops like a MacBook Pro. Its most notable feature is the 140W bidirectional charging, meaning it can not only output power at this rate but also recharge itself incredibly fast when paired with a compatible 140W charger. The use of GaNPrime technology contributes to a more compact and efficient design compared to older, silicon-based power banks of similar capability. It features two USB-C ports and one USB-A port, allowing for simultaneous charging of multiple devices, with intelligent power distribution to optimize charging speeds.
Key Features

- 24,000mAh Ultra-High Capacity: Sufficient power to charge an iPhone 14 almost five times, or provide more than a full charge for a 2021 MacBook Pro 14-inch.
- GaNPrime Technology: Anker’s advanced Gallium Nitride (GaN) based charging system allows for a smaller, lighter design with improved efficiency and less heat generation compared to traditional silicon-based chargers and power banks.
- Smart Digital Display: An intuitive display provides real-time information, including output/input wattage, remaining battery percentage, and estimated recharge time for the power bank or remaining use time for connected devices.
- Three-Port Output: Equipped with two USB-C ports (up to 140W total output) and one USB-A port (up to 18W output), enabling simultaneous charging of up to three devices.
- ActiveShield 2.0 Safety System: Monitors temperature 3 million times a day for safe and optimized charging, offering enhanced protection against overheating and overcharging.

- Power Output: The Anker 737 delivers up to 140W, significantly higher than the PowerCore III Elite’s 87W. This makes a crucial difference for power-hungry laptops, which can charge at their maximum speed with the 737. The PowerCore III Elite is still good for many laptops but might not hit their peak charging rate.
- Capacity: The PowerCore III Elite boasts a slightly larger 25,600mAh capacity compared to the 737’s 24,000mAh. However, this marginal difference is often negligible in real-world use.
- Technology: The Anker 737 utilizes cutting-edge GaNPrime technology, contributing to its more compact size relative to its power output and improved thermal management. The PowerCore III Elite uses older, standard battery and charging technologies.
- Features: A standout feature of the 737 is its smart digital display, offering real-time power metrics, which the PowerCore III Elite lacks, relying on simpler LED indicators. The 737 also supports 140W bidirectional charging, making its own recharge significantly faster than the PowerCore III Elite’s maximum 60W input.
- Price: The Anker 737 is typically priced higher due to its advanced technology and increased power output, while the PowerCore III Elite offers a more budget-friendly alternative for those who don’t require 100W+ charging speeds.
In essence, if you need the absolute fastest charging for high-demand devices and appreciate the technological refinements and informative display, the Anker 737 is the superior choice. If an 87W output is sufficient for your needs and you’re looking to save some money, the PowerCore III Elite remains a very capable option.
