The DeWalt DCE400D2 is a cordless PEX-A expander that runs on the 20V MAX battery platform. Its automatic rotating head turns the expander cone as it works for even expansion, and a full-trigger design lets you expand with one hand. It accepts DeWalt PEX heads and also fits Milwaukee and Uponor heads, so plumbers already invested in those systems can use it. Owners rate it highly for speed and consistency on PEX-A jobs; it is a specialist tool, so it only makes sense if you install PEX-A regularly.
