Both tools operate at a maximum speed of 3000 RPM, which allows for quick fastening and loosening of bolts. The AOBEN's powerful 21V engine is designed for efficiency, making it ideal for demanding tasks. While the SEYVUM also features a powerful brushless motor, its slightly lower torque may not be suitable for heavy-duty applications.
Battery and Charging
In terms of battery performance, both impact wrenches come with a 4.0Ah lithium-ion battery, ensuring ample power for extended use. The AOBEN model can be fully charged in a few hours, while the SEYVUM's battery charges in just 2 hours, providing quicker turnaround times.
