Highlights

Brushless Motor: SundpeyPRO 1/4 cordless impact driver features a high-efficiency brushless motor with a maximum torque of 2832 in-lbs. The brushless architecture eliminates the carbon brush assembly, effectively reducing physical friction and wear. This design supports smooth rotation and precise torque adjustment, delivering higher power conversion efficiency. Whether tightening long screws, installing expansion bolts, or handling large-volume assembly tasks, this power impact drivers handles a wide range of tasks with ease — making it a dependable choice for furniture assembly and daily maintenance
2 x 21V 2.0Ah Batteries: SundpeyPRO brushless impact driver comes with two 2.0Ah batteries for longer runtime. Use one while the other charges for uninterrupted, high-efficiency work. A battery indicator displays remaining power in real time, making charge planning simple. The fast charger fully charges a single battery in 1–1.5 hours, while each charge provides approximately 30 to 90 minutes of runtime. (The duration depends on the speed setting and the material being processed.) Multiple built-in safety protections—including overcharge (max 21.12V), overcurrent (max 62A), and over-temperature (cut-off at 75℃)—ensure safe and reliable operation
4 Speed & 3 Working Modes: SundpeyPRO 1/4 inch impact driver features 0–3200 RPM 4-speed control and three material-specific modes (wood, thin iron, thick iron). Users can freely match speed settings with material modes in real time. The system adapts precisely to material hardness, preventing damage to workpieces and thread stripping caused by excessive torque. It ensures precise and controllable power output for every tightening operation, while improving operational smoothness, work efficiency, and consumable durability
Built-in ring LED light: SundpeyPRO battery powered impact driver features a built-in ring LED that casts uniform, shadow-free light around the bit. Unlike single-point LED lights, it can illuminate every corner and crevice, so screws are always clearly visible, helping you complete fastening tasks more efficiently and easily. The light uses a sensor-activated design; pulling the trigger turns it on immediately, and it automatically turns off 10 seconds after releasing the trigger, giving you ample time to align the next screw
1/4-Inch Steel-Ball Chuck Design: SundpeyPRO cordless electric impact driver bit features a durable all-metal chuck for quick, tool-free bit changes. This design significantly reduces bit-change time, whether you're installing wall-mounted shelves, repairing appliances, doing woodworking DIY, or maintaining your yard, allowing you to focus more on the task at hand. (Note: Minor bit movement after installation is normal)
Forward/Reverse with Smart Slowdown Speed-Down: SundpeyPRO compact impact driver allows for quick toggling between tightening and loosening modes. In reverse mode, press the scene mode button (red indicator lights up) to activate smart slowdown protection. It automatically slows down the moment a bolt loosens, ensuring smooth output, preventing screw slippage, and reducing the risk of screws falling for safer operation. Press the button again (green indicator on) to deactivate smart slowdown and return to standard reverse speed
Impact Driver Kit for Various Projects : 1 x 1/4" impact driver cordless, 2 x 2.0Ah batteries, 1 x charger, 14 x socket set(5,5.5,6,7,8,10,12mm; 3/16",1/4",9/32",5/16",11/32",3/8",7/16"), 10 x screwdriver bit(5/32,3/16,1/4; PZ1,PZ2, PZ3; T15,T20,T25,T30), 1 x storage case, 1 x user manual. In addition, we provide a 3-year product support! If you have any questions about the small impact driver, please find us, and we will solve your issues promptly

Detailed Review

The SundpeyPRO 21V Cordless Impact Driver Set delivers high-torque fastening for household maintenance, furniture assembly, and DIY projects. Powered by a carbon-free brushless motor reaching up to 2832 in-lbs of torque, it provides smooth rotation and power efficiency for driving long screws or anchoring hardware without excessive physical wear on the tool.

Precision is built into the drive controls, offering four speed stages up to 3200 RPM alongside three material-specific modes for wood, thin iron, and thick iron. This setup helps prevent workpiece damage and stripped threads by tailoring output to the material. For removal tasks, an intelligent reverse mode automatically slows rotation the moment a bolt breaks loose, keeping hardware secure and preventing dropped fasteners.

Workplace visibility and convenience get solid attention with the 1/4-inch all-metal chuck and shadow-free ring LED. Pulling the trigger turns on the multi-point light, which lingers for 10 seconds after release to help line up the next fastener. Power is supplied by two included 21V 2.0Ah lithium-ion battery packs that recharge in 1 to 1.5 hours on the supplied charger, supported by built-in overcharge, overcurrent, and 75-degree Celsius thermal shutoff protections.

When considering trade-offs, note that the all-metal chuck design exhibits minor bit play after insertion, which is a normal characteristic noted by the manufacturer. Runtime also fluctuates considerably between 30 and 90 minutes depending on speed settings and workload resistance, though having two batteries helps mitigate downtime.

Verdict: The SundpeyPRO 21V set is a capable choice for homeowners and DIYers who want high torque, smart speed controls, and a complete bit and socket accessory kit ready to go out of the case.
