Bought for installing a fence, repairing a roof, and renovating an apartment. By itself, a screwdriver copes with all these tasks with a bang. The only thing in my opinion is a short cord that limits maneuverability during operation. But unlike with batteries, constant charging is not required. Specifications you can see on the Internet. Confirmation of purchase π you can see photos 3 and 4. The screwdriver itself is in photos 1 and 2
