Anker Nano II (65W) High-Output AC Adapter Regular price: ¥4,490 Size: Approximately 36 x 42 x 44 mm Weight: Approximately 112g *Quoted from the official website below [Rapid Charging for a Wide Range of Devices] With a 65W output supporting USB Power Delivery (PD), this USB charger can rapidly charge a wide range of devices, from smartphones to laptops. You don't need to carry different chargers for each device. Compatible with MacBooks and PD-compatible Windows PCs: With a maximum output of 65W, it can rapidly charge not only MacBooks but also various PD-compatible Windows PCs. It is very lightweight and compact compared to the AC adapters included with typical Windows PCs, making it comfortable to use for remote work in cafes or at home. [Ultra-Compact Design] Approximately 60% smaller than conventional chargers with 60W or more output, and the foldable plug makes it convenient to carry. It has been designed to be lightweight and compact. Uses proprietary "Anker GaN II" technology: GaN (Gallium Nitride) USB chargers have evolved to the second generation. By innovating the power IC and circuit design, the switching frequency has been increased by approximately twice compared to our previous models, reducing the size of electronic components, and implementing heat and EMI (noise) countermeasures, achieving a smaller and lighter design while meeting strict safety standards. [Compliant with International Safety Standards] It complies with the technical standards set by the Electrical Appliance and Material Safety Law, as well as the international safety standard IEC 62368-1. [Active Clamp Flyback (ACF) Power Circuit System] By adopting the ACF power circuit system, soft switching (a power technology that switches when the voltage or current is zero) is realized, further improving power conversion efficiency.
