The Astrum UCC240B — 240W USB PD 3.1 EPR. One Cable for Everything.
The Astrum UCC240B is built for the highest USB-C power standard available. USB PD 3.1 Extended Power Range supports up to 240W output at 48V/5A, replacing proprietary laptop charger bricks for the most demanding devices.
With an EPR-rated E-Marker chip, braided jacket, SR bend protection, Black and White colour options, it is built for high-power USB-C charging across phones, tablets, laptops, gaming laptops, and professional workstations.
What is USB PD 3.1 EPR?
USB PD 3.0 maxed out at 100W using 20V/5A. USB PD 3.1 Extended Power Range adds 28V, 36V, and 48V power levels, reaching up to 240W at 48V/5A.
This is the power level needed by gaming laptops and professional workstations for full-speed USB-C charging — previously only possible with proprietary barrel connectors.
EPR E-Marker — The Right Chip
A standard E-Marker cable caps at 100W. An EPR-rated E-Marker communicates 50V/5A capability to the charger, enabling EPR mode. Without the EPR E-Marker, a 240W charger silently falls back to 100W.
One Cable for Every Device
Phone at 27W. MacBook Air at 61W. MacBook Pro 16″ at 140W. Gaming laptop at 240W. USB PD 3.1 negotiates power automatically, so each device draws only what it needs. Fully backward compatible.
Braided + Two Lengths
The braided jacket is built for daily use, with a 5,000+ bend lifespan and SR protection at both ends. Available in 2.0m and 3.0m lengths.
Available in Black and White.
