We purchased 12 GaN chargers at retail price. Each charger was connected to a USB-C power meter (Fnirsi FNB58) and run at its rated maximum wattage for 30 continuous minutes. We recorded output wattage every 60 seconds and logged peak surface temperature. Only the 5 chargers that sustained ≥95% of rated output made this list. The Anker 735 Nano II is our top pick for most travelers. It delivers 63.5W tested output, weighs 110g, and has 3 ports. The Satechi 100W Pro is best for power users with 97.2W tested output. The Nekteck 60W GaN at 95g is the lightest pick. The Amazon Basics 65W is the best budget option at $15.29. The Ugreen Nexode 300W is the desktop beast for multi-device setups.
