Engineered with Gallium Nitride (GaN) technology, this dual-port charger provides up to 47W of total output—perfect for simultaneously charging your smartphone and tablet or quickly powering a lightweight laptop like the MacBook Air. Whether you’re traveling, working from a café, or commuting, its foldable plug and ultra-slim profile make it one of the most travel-friendly high-power chargers available.

Key Features

• Dual High-Speed USB-C Ports: One port outputs up to 27W while the other delivers 20W, enabling simultaneous fast charging of two devices—ideal for pairing an iPhone with an iPad or charging your phone and earbuds together.
• Up to 47W Single-Port Power: When used alone, either USB-C port can deliver full 47W output, fast enough to charge a MacBook Air from near-empty in under an hour—great for professionals and students who need quick laptop top-ups on the go.
