The Anker 747 Charger (GanPrime 150W) is an impressive entry into the world of USB GaN chargers. With a stellar 150W maximum power output, this device stands tall in a market dominated by lesser power offerings while boasting a design that’s 38% smaller than most OEM chargers with a similar output. With size and power combined in a perfect blend of portability and functionality, the Anker 747 seems like an absolute game-changer.

The charger sports four ports — one USB-A port, capable of up to 22.5W, and three USB-C ports that allow for simultaneous charging of multiple devices, up to 150W. Despite the compact size, there’s no compromise on performance, making the Anker 747 Charger a perfect companion for power users and frequent travelers. In this review, we will dive deep into the Anker 747 Charger, exploring its features, benefits, and the unique value proposition it brings to the table.

Design and Build Quality

The Anker 747 features a robust and compact design with dimensions of 2.66 x 1.22 x 2.41 inches. Weighing 231.5 grams, the charger is impressively light. It is crafted using good quality material that contributes to its excellent build quality. The charger boasts a dark grey body which beautifully complements its titanium-color front, offering it a sleek and modern appearance. One of its noteworthy features is the retractable plug prongs which ensure maximum compactness, making it highly portable and ideal for travel.

When compared with its competitor, the Apple 140W charger, the Anker 747 exhibits significant advantages in terms of size and weight. The Apple charger, with dimensions of 5.52 x 4.64 x 1.28 inches, is significantly larger; the Anker 747 is significantly smaller by volume. Additionally, the Apple 140W charger weighs 340 grams, making it approximately 47% heavier than the Anker 747. Therefore, the Anker 747 offers greater portability due to its compact size and lighter weight.

Power Output and Compatibility

This USB charger, engineered with top-tier technology, boasts an impressive maximum aggregated power of 150W when utilizing multiple ports. It is designed so that if several devices charge simultaneously, the power is intelligently split amongst them, up to the maximum of 150W.

The charger is equipped with both USB-C (three) and USB-A ports (one), catering to various devices. For high-powered needs, any of its USB-C ports can deliver up to 100W of power, making it suitable for charging energy-intensive devices, including laptops that support USB-C charging. This high capacity enables swift and reliable power delivery to keep your devices running efficiently.

Meanwhile, the USB-A port provides a maximum charging speed of 22.5W. This is ideal for legacy devices not equipped with the latest USB-C technology. Therefore, this charger is an ideal solution for users with a mix of modern and older-generation devices.

The flexibility of this charger is further enhanced by its compatibility with a broad range of protocols, including USB Power Delivery (USB PD), Apple, and Samsung, among others. Since there might be intellectual property licensing involved, some cheap chargers might not be compatible with some or all the protocols. Such broad compatibility ensures that you can charge virtually any USB device without worrying.

To assist users in understanding the possible charging combinations and maximizing the charger’s efficiency, Anker provides detailed information in their official specifications. This resource is invaluable for taking full advantage of this charger’s capabilities and getting the best possible performance out of your devices.

Charging Performance

According to our tests, this USB charger is a reliable power supply for various well-known devices, including 100W laptops. The efficacy and compatibility of the charger have been tested and verified, showcasing its efficient functionality in accordance with the power requirements of different devices.

A noteworthy feature of this charger is its adaptive power output. It’s important to note that charging speed is primarily determined by the device itself (with compatible protocol), as it decides how much power it pulls. If the device being charged uses a protocol unknown to the charger, the process will default to something using less power such as a more basic USB charging method.

One of the key safety features of this charger is its dedicated overheating protection. The charger checks its temperature an impressive 3 million times per day, constantly monitoring its thermal performance to prevent any potential overheating. This diligent oversight contributes to a safer charging environment and promotes longevity in both the charger and the devices it powers.

The USB charger has demonstrated its power output capability, confirming its ability to provide an aggregate limit of up to 150W. This robust power output allows it to charge multiple devices simultaneously effectively, or power high-demand devices like laptops. Check our test data below:

Smartphones max Watts
Galaxy S23 Ultra 41.9
Galaxy S22 Ultra 29.5
Honor Magic 5 Pro 28.7
OnePlus 11 5G 19.5
Laptops max Watts
Lenovo Z16 91.6 (charging)
Lenovo Slim i9 14 65.7 (charging)
Lenovo X1 Extreme Gen4 60 (USB-PD) running GB
Lenovo X1 Carbon Gen 10 52.6 running GB

Note that devices such as the OnePlus 11 5G are capable of charging much faster, but only using proprietary protocols and the appropriate same-brand charger.


This USB charger is straightforward to use and transport. Its user-friendly design ensures that you can operate it without any hassle. Moreover, the compact and lightweight construction makes it an ideal travel companion. It’s a must-have device for those who are always on the go and could quickly become the only charger you need.

It should be noted that no cable was provided in the box. Some competitors do provide a cable along with the charger in case the user does not have a spare high-power USB cable, such as laptop owners.

No foreign electric plug adapter was provided in the box, which I am okay with since I own quite a few already. That said, new users should take into account the fact that competitors may offer these small accessories and that might impact the overall value proposition.

Pros and Cons

The Anker 747 USB charger’s compact design is impressive, offering easy portability. Despite its size, it provides a robust 100W maximum power for a single device and an aggregate 150W output for multiple devices. Its broad compatibility includes tech giants like Apple and Samsung, adding to its versatility.

On the downside, the Anker 747 is priced at a steep $110, which could be a deterrent for some. Additionally, the absence of a foreign plugs adapter limits its usefulness for international travel.

Future enhancements include embracing the 240W output that USB PD now supports, allowing faster charging for power-demanding devices. Also, expanding compatibility by licensing protocols from OEMs like OnePlus, Oppo, Honor would enhance its appeal to a wider audience.


In conclusion, the Anker 747 GanPrime 150W charger (official page, Amazon page) is an outstanding product based on real-world data and experiences. Considering its size, its performance is remarkably impressive, making it a reliable and efficient charging solution. I highly recommend the Anker 747 to anyone needing an extremely compact and powerful USB charger. In fact, it is the best in its category at publication time.
