The Astrum UCC100B — 100W USB-C PD. E-Marker. Braided.
The Astrum UCC100B is a 100W USB-C PD cable built for laptop charging. The built-in E-Marker chip unlocks 5A power delivery — without it, USB-C cables are limited to 60W regardless of charger wattage. With a braided jacket, SR bend protection, and 1.0m and 2.0m length options, it is built for high-power everyday use.
E-Marker — The Chip That Unlocks 100W
USB-IF specification requires an E-Marker chip in any cable delivering more than 60W. The E-Marker communicates 5A capability to the charger. Without it, the cable is limited to 60W. With it, the cable supports full 100W output at 20V/5A.
100W at Full Speed
Supports high-speed charging for USB-C laptops up to 100W, including MacBook Pro 14″ and 16″, Dell XPS, HP Spectre, Surface Pro, Lenovo ThinkPad, and compatible gaming laptops.
Braided + SR + Both Lengths
The braided jacket is built for daily use, with a 5,000+ bend lifespan and SR protectors at both ends. Available in 1.0m for desk setups and 2.0m for extended reach.
Backward Compatible
Works with all USB-C devices. Lower-wattage devices draw only the power they need.
