Product Details
✓【Extended Runtime Cordless Polisher Kit】 Designed with two upgraded 21V 4000mAh rechargeable batteries, this cordless car buffer delivers significantly longer working time for complete vehicle detailing without frequent battery changes. Features a quick-release locking mechanism for smooth battery swaps: simply press the release latch firmly all the way down to slide the battery out effortlessly. Ideal for SUVs, trucks, boats, and professional detailing jobs. Compatible only with the original Niusken battery system.
✓【6 Variable Speeds & Smart LED Display】 Choose from six variable speeds (2800–5800 RPM) for waxing, polishing, paint correction, and scratch removal. The built-in LED display shows both speed level and remaining battery power in real time. The 8mm dual-action random orbital movement delivers even polishing with reduced vibration, lower noise, and better heat control for safer paint correction.
✓【Dual 4000mAh Extended Runtime & Secure Fit】 This upgraded kit includes two high-capacity 21V 4000mAh lithium-ion batteries and a fast charger, providing substantially longer runtime than standard battery configurations. Designed for a tight, secure fit that prevents accidental loosening during high-speed polishing. Spend more time polishing and less time recharging.
✓【Lightweight & Comfortable to Use】 Despite the larger-capacity battery system, the polisher remains lightweight at only 3.9 lbs. The ergonomic rubberized grip reduces fatigue during extended polishing sessions, while the cordless design provides complete freedom for use in garages, driveways, workshops, or outdoor detailing environments.
✓【18-Piece Complete Detailing Kit】 Everything needed for professional car detailing is included: 2×5" flat foam pads, 2×6" flat foam pads, 2×5" wave foam pads, 2 wool pads, 2 microfiber bonnets, 2 non-woven bonnets, 6 sanding discs, fast charger, carrying bag, and more. Suitable for polishing cars, motorcycles, boats, RVs, furniture, marble, wood, metal, and other painted surfaces.
✓Important Note: For optimal performance, please fully charge the battery before first use; ensure it is clicked firmly into place and long-press the power button to start. Please note that our battery system is uniquely designed for this model and is not compatible with DeWalt batteries or other third-party battery brands. If you have any questions regarding battery compatibility, charging, or operation, our professional technical team is available 24/7 to provide expert guidance and troubleshooting.
