Our soft starters are software-controlled using the latest technology.

The GS11 is the bigger brother of the GS10, featuring a 5-20R receptacle and 12AWG gauge conductors inside and out, but otherwise is constructed exactly the same. 

Adding a soft start function to your power tools, pumps, etc. has never been so simple, just plug it in! And the best part, it's so simple and versatile that you can soft start your other compatible equipment as well.  You can even leave multiple devices plugged into the soft starter at all times via a splitter or power strip. Just remember, only use one device at a time and make sure that the GS10 or GS11 maximum current rating is not exceeded by your equipment. Onward!



-This product is not intended to reduce overall current consumption.
-This product model is not compatible with digital applications, air compressors, air conditioners, or dehumidifiers.

Originally built for use with universal motor power tools, this soft starter has since evolved to provide you so much more with a wide-variety of applications:

  1.  Prolonging equipment life
  2.  Noise reduction

  4.  Preventing nuisance circuit breaker tripping
  5.  Increased comfort with jumpy power tools
  6.  Multi-level safety factor improvement
  7.  Electrical injury prevention
  8.  Electrical fire prevention

      Works as expected. Solved issue.

      Saves me alot of trips to the breaker panel

      Using it on a 12-inch Milwaulkee miters, 10-inch Delta table saw. Over 100 cuts and not one trip to reset AGCI breaker. Before I got the GS-11, I could not even use the miter saw on the AGCI circuit. Did not work on variable speed Hilti hammer drill (not surprisingly according to specs)
