Overview
The SOARFLY BS-2 is a 21 volt cordless impact tool built for driving and removing fasteners under high torque. At 3.2 kilograms it is a substantial handheld unit, closer in heft to a heavy-duty impact wrench than a compact driver, so it suits users who need sustained torque over all-day comfort.
Impact tools in this weight class trade portability for holding power, and the BS-2 leans toward the latter. Buyers should confirm which battery and accessories are included before ordering, since neither is broken out in the listing data. Its appeal is straightforward: torque for stubborn fasteners rather than finesse for everyday screws.

Who it's for
Suited to anyone tackling lug nuts, lag bolts, or other high-torque fastening jobs around the home, garage, or job site. Not the pick for someone who mainly drives small screws and wants a light, one-handed driver.
Strengths and trade-offs
Drawn from this product's published specifications.
- High voltage platform for demanding fastening tasks
- 600 purchased in the past month shows active current demand
- Weight of 3.2 kilograms makes it heavier than compact impact drivers
- No battery, charger, or accessory detail provided
Performance notes
Torque on impact tools comes from a hammer-and-anvil mechanism that delivers rotational force in rapid bursts rather than constant twist, easing wrist strain on tough fasteners. The 21 volt rating and 3.2 kilogram body point to a tool built for that kind of repeated high-load work rather than fast, light-duty driving.
