Overview
A trade user or serious DIYer gets a cordless impact driver with a two amp hour lithium ion battery and a charger in the listing. The listing names variable speed, and the maximum chuck size is quarter inch.
A kit style setup with the battery side covered lets a buyer start working without hunting for a power source. The limitation is data quality, because the torque unit reads foot pounds and the listing gives no warranty detail.
Who it's for
Household and light trade fastening suit this driver. A professional matching torque to a spec should confirm the torque rating with the maker, since the unit shown looks wrong.
Pros and cons
- Charger listed as included
- Lithium ion battery
- Torque unit looks wrong
- Warranty terms absent
- Heavy listed weight
- Number of batteries not stated
Performance notes
Fastening force comes from the motor and impact action, and the battery capacity sets run time per charge. Variable speed lets the user ease into a screw before driving it home. The torque figure cannot be trusted as written, so compare it with maker data.
