Overview
The NA-QZJ is a cordless impact driver from NAWIN built around a 16.8-volt battery, running at up to 3,450 RPM in a body that weighs about 2 pounds. It suits users who want a light, one-handed driver for repeated screw driving.
Impact drivers trade smooth torque for repeated rotational hits, which is what lets a tool this light drive long screws without stalling. NAWIN does not publish torque or impact-per-minute figures here, so the 3,450 RPM figure describes free speed rather than driving force. At 2 pounds it sits toward the lighter end of the category, which matters most for overhead or repetitive work.
- 16.8 volt DC battery power
- 2 amp draw
- 3,450 RPM free speed
- About 2 pounds
Who it's for
Suits anyone doing repeated deck, fence or furniture assembly who wants a driver light enough to hold overhead for stretches at a time. Less suited to users who need a full torque spec sheet before buying, since NAWIN has not listed one here.
Pros and cons
- Light at about 2 pounds for a driver
- 16.8V battery platform
- 3,450 RPM free speed
- No torque or impact-per-minute spec listed
- No stated chuck or bit-holder type
Performance notes
Impact drivers deliver rotational force in short bursts rather than continuous torque, which reduces cam-out on long screws and cuts down on wrist strain compared to a standard drill driver. The 3,450 RPM figure is a free-speed number, not a loaded driving speed, so actual screw-driving pace will vary with fastener length and material.
