I've already gone through a bunch ofcomrdless tools - from small electric screwdrivers to 36-volt self-propelled lawn mowers - everything works fine! For any grinders and circulars, it is highly desirable to put them at least 2 in parallel - these tools require high currents, especially when the disk gets stuck in the material. For less voracious gadgets, their power and capacity will be enough for the eyes! Definitely recommend! How even a single-speed screwdriver turns with them can be seen here - ? t=604
I've added some photos to help enhance the overall impression of my review.
