It runs on two rechargeable 21V batteries, giving you up to 100 minutes of cordless use, which is enough to finish most cars in one session. The polisher has a brushless motor offering six speed levels from 2800 to 5800 RPM, allowing you to adjust the speed for different tasks easily. Its 6-inch pad size and orbital motion help provide smooth, swirl-free polishing results.

Weighing about 3.3 pounds, it is relatively lightweight and comfortable to hold thanks to its ergonomic grip, making it easier to maneuver around your vehicle. The LED display is a nice touch, showing battery status and speed clearly during use. Plus, the included 18-piece accessory kit covers various polishing needs across different surfaces, not just cars but also boats, furniture, and more.

While 3.3 pounds is light for many users, some may find it a bit heavier compared to ultra-compact models, which could affect longer polishing sessions. The battery capacity is suitable for casual or moderate work but might not suffice for very large or multiple vehicles without recharging. This product suits beginners and DIY detailers well but may lack the power or durability preferred by professional detailers working daily. For those seeking a cordless polisher with flexible speed options, decent battery life, and a full accessory set for various surfaces, this Niusken model represents a solid choice. Its ease of use and no-cord design make it especially appealing for hobbyists and newcomers to car polishing.

The variable speed trigger allows for precise control, which is a significant advantage for detailed work.

One notable feature is the premium electronic motor feedback that maintains consistent speed and power, even under load, ensuring reliable performance during extended use. The lock-on switch is also designed to reduce user fatigue, making it more comfortable for long polishing sessions.

This makes it suitable for tackling tough jobs efficiently.

Battery life is a crucial aspect of cordless tools, and this polisher offers reliable run-time, although the actual usage time may vary depending on the intensity of the task. It’s important to note that the batteries are sold separately, which could be an additional cost for users.

The variable speed settings allow for versatile use, making it easy to switch between different polishing tasks. This feature will benefit both beginners and experienced users who need finer control during various applications.
