【PSE Certified & Multiple Safety Protection Features】: This AC adapter is a PSE-marked electrical appliance that has been confirmed to meet technical standards and complies with the international safety standard IEC 62368-1. It has multiple automatic protection features, including short-circuit protection, current control, over-voltage protection, over-current protection, device overheating protection, and PD charger body overheating protection, to securely protect your devices and the charger itself, ensuring safe and reliable use. 【Simultaneous Fast Charging of 4 Devices】: Equipped with 4 ports: USB-C x 3 + USB-A x 1, it can simultaneously fast charge up to 4 devices such as MacBook Pro/Air, laptops, tablets, and smartphones, eliminating the need to carry multiple chargers. It solves the problem of insufficient outlets and messy wiring, keeping your office or desk tidy. It's foldable and easily fits in your bag when carrying it! Its compact design makes it easy to use at home, work, or while traveling. 【Built-in Safe Smart Chip】: Built-in smart chip prevents overcurrent, overheating, and short circuits, supports PD/QC/PPS standards. When multiple ports are used simultaneously, it optimally distributes the 100W output according to the power requirements of the connected devices, enabling efficient and smooth charging. 24-hour continuous current control suppresses heat generation, achieving stable and fast charging at low temperatures. Furthermore, it has a silent design, allowing you to use it with peace of mind even while sleeping. 【Up to 100W Ultra-High Output PD Charger】: When using a single port (Type-C), it provides a maximum output of 100W, significantly reducing the charging time not only for smartphones that support fast charging but also for laptops and other devices that take a long time to charge. A MacBook Air 14 can charge from 0% to 70% in about 45 minutes, and an iPhone 16 Pro Max can fast charge from 0% to 70% in 30 minutes! It's about 3 times faster than conventional USB chargers, saving you over an hour of charging time and more than 2 hours of time every day. 【GaN Technology & Wide Range of Applications】: Our Type-C charger uses "GaN (Gallium Nitride)," a next-generation power semiconductor material with high withstand voltage and power efficiency. It sufficiently improves energy exchange efficiency, suppresses heat generation, and achieves high-efficiency fast charging while maintaining safety. It also supports voltages from 100 to 240V, making it convenient to carry for business trips abroad, at home, at work, or while traveling.
