The Einhell Power X-Change 18V Cordless Detail Sander is a compact orbital sander with a high fixed speed of 24,000 OPM, designed for precision work on small surfaces. Its main trade-off is the lack of variable speed control and the need to purchase batteries separately. It is best suited for hobbyists and DIYers who already own Einhell Power X-Change batteries.

The BLACK+DECKER BDCMS20B is a cordless 20V MAX* bare-tool mouse detail sander designed for sanding in tight corners and small spaces. It features a compact ergonomic design with an interchangeable detail finger attachment, variable speed up to 12,000 RPM, and a hook-and-loop sandpaper system for easy changes. While it offers excellent portability and control, the requirement to buy batteries separately and the lower speed compared to corded models are significant considerations.
