EaseUS Disk Copy is a dedicated disk cloning utility designed to help users copy data from one hard drive to another. It creates a sector-by-sector copy, ensuring that absolutely no data is lost during the transfer. You can create a WinPE bootable USB

The term "Portable" refers to a specific version of the software. Unlike standard software that requires installation (writing files to your Program Files folder and modifying the Windows Registry), a portable application is a standalone executable. It can be run directly from a USB flash drive or an external hard drive without being installed on the host computer. Their hard drive is clicking (failing)

Even in portable mode, if you boot a secondary Windows installation (like from a WinPE), the tool can often perform "hot" clones of non-system volumes.

Unlike basic copy-paste, EaseUS Disk Copy Portable reads every sector—including empty space, deleted files (forensically), and hidden system partitions. This ensures bootable drives remain bootable.

The official bootable media creation is a feature of the paid version (Technician or Professional). The free version of EaseUS Todo Backup limits backup/cloning speed and file size. To create a true portable USB for commercial use, you need a valid license.
