Jruav Cordless Buffer Polisher – 7230 RPM, 21V, 4.0Ah, 29-Piece Car Detailing Kit

Power, Performance, and paint-safe operation

Meet the Jruav Cordless Buffer Polisher, a versatile tool designed for polishing, waxing, scratch refinement, and more. It uses a high-efficiency brushless motor that delivers up to 900W of power and reaches speeds up to 7230 RPM. An integrated buffer overload protection helps prevent excessive pressure from affecting the finish, offering steady control and a safer detailing experience.

In real-world use, you can move from delicate waxing to more aggressive cutting as you gain confidence, thanks to thoughtfully chosen speed settings and a responsive control system. The result can feel smooth in hand and precise in action, making complex jobs feel more approachable without sacrificing performance.

Battery, charging, and runtime

The cordless setup includes two 21V 4.0Ah batteries and a fast charger. A full recharge takes roughly 90 minutes, so you can swap in the second battery to extend your session and minimize downtime. A note for first-use: charging before the initial run helps you get the most from each session.

• Two high-capacity batteries enable longer polishing without frequent interruptions.
• Fast charging reduces downtime between tasks.

Control, handling, and versatility

Weighing about 4 lbs, the polisher features a rubber-coated, anti-slip exterior for comfortable, secure handling. It supports two control modes: a button-based approach (1/2/4/6) and a knob-based approach (1–6); you can’t use both at once, so switch modes with the switch off and wait for the indicator to reset. It is compatible with discs sized 125mm, 150mm, and 180mm for broader applicability.

• 6 adjustable speeds cover waxing, polishing, defect removal, and DIY cutting.
• Lightweight design helps reduce fatigue during extended sessions.

Applications and kit contents

Designed for professionals and enthusiasts alike, this polisher handles polishing, swirl removal, scratch repair, and more on painted surfaces. It is also suited for boat sanding, furniture refinishing, and floor maintenance when paired with the included accessories.

The 29-piece kit brings a complete detail setup, including multiple pad types (flat foam, wave foam, and wool polishing pads), 2000-grit sandpaper, a backing plate, two batteries, a fast charger, handles, and a hex driver, so you can start a project right away.

• Three pad types to tackle different tasks: flat foam, wave foam, and wool.
• Comprehensive set that supports polishing, finishing, and light material prep for various surfaces.
