Astrum USB-C 240W PD 3.1 EPR Cable, E-Marker, Braided – UCC240B (Black)

𝟮𝟰𝟬𝗪 𝗨𝗦𝗕 𝗣𝗗 𝟯.𝟭 𝗘𝗣𝗥 — 𝗧𝗛𝗘 𝗛𝗜𝗚𝗛𝗘𝗦𝗧 𝗨𝗦𝗕-𝗖 𝗣𝗢𝗪𝗘𝗥 𝗦𝗧𝗔𝗡𝗗𝗔𝗥𝗗 — USB Power Delivery 3.1 with Extended Power Range (EPR) delivers up to 240W (48V/5A) — nearly 2.5× the 100W maximum of PD 3.0. EPR adds new voltage levels of 28V, 36V, and 48V above the 20V cap of PD 3.0, enabling USB-C to replace the proprietary barrel connectors on high-performance gaming and workstation laptops. 𝗘𝗣𝗥 𝗘-𝗠𝗔𝗥𝗞𝗘𝗥 𝗖𝗛𝗜𝗣 — 𝗠𝗔𝗡𝗗𝗔𝗧𝗢𝗥𝗬 𝗙𝗢𝗥 𝟮𝟰𝟬𝗪 𝗗𝗘𝗟𝗜𝗩𝗘𝗥𝗬 — A standard E-Marker chip caps at 100W (20V/5A). The UCC240B contains an EPR-rated E-Marker that communicates 50V/5A capability to the charger — required by the USB PD 3.1 specification before EPR mode is enabled. Without an EPR E-Marker, a 240W charger silently falls back to 100W. The UCC240B carries the right chip. 𝗪𝗛𝗜𝗖𝗛 𝗟𝗔𝗣𝗧𝗢𝗣𝗦 𝗡𝗘𝗘𝗗 𝟮𝟰𝟬𝗪? — 𝗚𝗔𝗠𝗜𝗡𝗚 𝗔𝗡𝗗 𝗣𝗥𝗢𝗙𝗘𝗦𝗦𝗜𝗢𝗡𝗔𝗟 𝗚𝗥𝗔𝗗𝗘 — High-performance gaming laptops (ASUS ROG, Alienware, Razer Blade, MSI) and workstation laptops (HP ZBook, Dell XPS 17, Lenovo ThinkPad P-series) require more than 100W for USB-C charging at full speed. MacBook Pro 16" M4 Pro/Max draws up to 140W. These devices need EPR — or they throttle charge speed on a 100W cable. 𝗕𝗥𝗔𝗜𝗗𝗘𝗗 𝗖𝗔𝗕𝗟𝗘 — Braided jacket handles 5,000+ bends for sustained high-power desk use. SR protectors at both USB-C ends. 2.0m for standard desk charging reach. 𝗙𝗨𝗟𝗟𝗬 𝗕𝗔𝗖𝗞𝗪𝗔𝗥𝗗 𝗖𝗢𝗠𝗣𝗔𝗧𝗜𝗕𝗟𝗘 — 𝗪𝗢𝗥𝗞𝗦 𝗪𝗜𝗧𝗛 𝗔𝗟𝗟 𝗨𝗦𝗕-𝗖 𝗗𝗘𝗩𝗜𝗖𝗘𝗦 — A 240W EPR cable is the single cable that works for every USB-C device: phones at 18–27W, tablets at 30–65W, MacBook Air at 45–67W, MacBook Pro at 96–140W, gaming laptops at 140–240W. USB PD 3.1 negotiates down automatically. One cable replaces all others.
