The Anker 747 Charger (GaNPrime 150W) is a multi-port GaN power adapter targeting users with multiple devices. We subjected it to rigorous testing, measuring delivered wattage under various load conditions and evaluating thermal performance. It offers a high power density, but thermal management introduces some limitations.
What You’re Paying For
The primary draw is the high power output from a relatively compact GaN package. The three USB-C ports and single USB-A port offer flexibility. The advertised 150W is achievable, but only under specific single-device conditions. The included cable is adequately thick and feels durable, capable of handling the high amperage. The GaN technology allows for higher efficiency compared to older silicon-based chargers.
The Compromise
Sustained output at the advertised 150W is optimistic. When multiple ports are in use, power is distributed, and individual port output is reduced. Thermal throttling becomes noticeable under heavy, sustained multi-device loads, leading to temporary power reductions. The ‘Power Delivery 3.1’ claim is technically true, but rarely utilized in current laptops, so the benefit is limited.
Warranty and Value
Anker provides a standard warranty, which is a positive. The 747 Charger sits in the premium price bracket. While cheaper chargers exist, few offer this power density and port selection. Consider your actual power needs; if you rarely charge multiple high-draw devices simultaneously, a less expensive option might suffice. However, for those needing flexibility and high peak power, it’s a viable option.
Solid performance for a multi-device user, but be aware of thermal limitations.
