The Promate TRIPLUG‑PD18 solves this neatly by combining a compact universal plug adapter and fast dual-port charger in one palm-sized device. Slide-out plugs cover US/UK/EU/AU sockets, while built-in 18W USB‑C Power Delivery and Qualcomm Quick Charge 3.0 USB‑A power two devices simultaneously fast and smart.
Perfect for frequent flyers, business travelers, and digital nomads, this adapter mixes convenience, power, and protection in a compact package—no need for separate chargers or bulky converters.

Powerful Charging on the Go
USB‑C 18W Power Delivery (PD)

USB‑A Quick Charge 3.0
The second port supports QC 3.0, delivering up to 18W via USB‑A. It also negotiates voltage (5V/3A, 9V/2A, 12V/1.5A), allowing rapid charging of compatible devices—e.g., gaining ~70–75% charge in 30 minutes .
