【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 to prevent overcurrent, overheating, and short circuits, supports PD/QC/PPS standards. When using multiple ports 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 high-power output of 100W, which not only supports fast charging for smartphones but also significantly reduces charging time for laptops and other devices that take a long time to charge. A MacBook Air 14 can be charged from 0% to 70% in about 45 minutes, and an iPhone 16 Pro Max can be fast-charged 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 adopts "GaN (Gallium Nitride)," a next-generation power semiconductor material with high withstand voltage and power efficiency, which sufficiently improves energy exchange efficiency and suppresses heat generation, while maintaining safety, and achieving high-efficiency fast charging to reduce charging time. It also supports voltages from 100 to 240V, making it convenient to carry for business trips abroad, at home, at work, or while traveling.
