When testing charging speeds for various 100-watt or higher power adapters connected to an iPhone 13, Apple’s 140-watt power adapter proved to be super quick at refilling the MacBook Pro. However, it lacks multiple ports, which may be a drawback for some users within the Apple ecosystem. For those in need of a fast charger for ultraportable laptops, the Razer 130-watt GaN adapter is recommended for its speed, compact size, and included accessories. It’s important to pay attention to charging standards and power output when selecting a charger for optimal performance. Factors such as size, weight, and efficiency should also be considered, with GaN-based chargers offering a more compact design and higher power output. Testing involved draining devices to 10 percent battery and recording charge added every 10 minutes for an hour, using certified cables and selecting the port with the highest power output for charging stations with multiple ports. The testing covered a range of devices from smartphones to laptops, with GaN technology offering increased power efficiency and output. Overall, the best chargers were categorized based on power output, with consideration for compatibility with various devices and the potential for multi-device charging.
