ETOOLAB Car Polisher 21V, 8‑speed kit 🚗

This cordless car polisher from ETOOLAB combines portability and power for home detailing and light professional use, making paint correction, waxing and scratch removal easier to manage in driveways or small workshops. It offers eight variable speeds and a dual-battery system that aims to balance runtime and continuous operation according to the manufacturer.

Key Points

The machine is designed for one-handed operation thanks to a lightweight construction and a soft-start feature that reduces initial kickback. An LCD shows real-time parameters to help choose the right speed between 2,800 and 5,500 RPM, with slower settings for waxing and higher settings for polishing work. The 9 mm eccentric stroke provides an orbital motion suited to reducing minor imperfections without overly stressing the paint.

The kit is sold as a complete 22-piece set that includes spare consumables and storage solutions, so it is ready for detail sessions straight away. The battery hot-swap design allows you to replace a depleted cell with minimal interruption. Consider that the base plate is fixed at 150 mm, which gives stability but limits compatibility with some aftermarket backing plates.

Benefits

The cordless design removes cable management and allows work around vehicles without changing power sources, which is useful when detailing several panels or working outdoors. Two batteries extend working time and the hot-swap capability reduces downtime during longer sessions. The LCD and speed selection provide greater control over torque and aggressiveness, helping to choose gentler settings for soft finishes and stronger settings for heavier correction. The inclusion of a range of pads and towels means you can move quickly from compounding to finishing without sourcing additional accessories.

Usage Recommendations

Start with a lower speed and a soft foam or wool pad when testing a new vehicle surface, progressively increasing speed and pad aggressiveness only if necessary. Keep batteries charged and rotate them during extended jobs to maintain consistent motor output. Use the included microfibre towels to remove residues between passes to better assess progress. Remember that the fixed 150 mm base plate provides good stability, but if you prefer larger or smaller pads you will need to check compatibility before attempting modifications.

Note that run times are approximate and may vary with workload and ambient temperature, and that the non-removable backing plate restricts aftermarket pad options.
