The Einhell Professional CP-EP 18/125 Li BL Solo is a battery-operated random orbital sander that operates on the Power X-Change 18 V lithium-ion battery platform. This tool features a brushless motor that offers variable speeds ranging from 500 to 3,800 RPM with electronic speed control for precise polishing results. The 125 mm polishing pad with 8 mm eccentricity creates a random orbital motion that avoids sanding marks and achieves streak-free surfaces. The brushless motor technology provides higher power output and a longer lifespan compared to conventional brushed motors. Practical features include a soft start for smooth operation, continuous operation for longer tasks, and quick accessory changes with a hook-and-loop system. The ergonomic design includes a front handle and an additional side handle for comfortable, controlled handling during extended polishing sessions. The device comes with three polishing pads but requires the separate purchase of a Power X-Change battery and charger. The eccentric sanding action combined with variable speed control makes this polisher suitable for car care, wood finishing, and surface restoration where professional results are required. The battery-operated design offers mobility and convenience without compromising polishing performance, making it ideal for workshop and mobile care environments.
