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

The GS11 is the big brother of the GS10. It features heavier gauge conductors inside and out, but otherwise functions the exact 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 air compressors, air conditioners, or dehumidifiers.
-This product may not be compatible with digitally controlled application.

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
  3.  Preventing Brown outs and dimming lights
  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

      GS11 Universal Soft Starter (20A max. Heavy duty)

      Reviewer avatar
      Got it for my router and now I use it for everything else too.

      The soft start circuit in my half inch Porter Cable router quit and after opening it up to repair it, I saw how skimpily the soft start circuit in it is built and I didn't really want to repair it only for it to puke again later.
      I checked around for another option and luckily I found the GS11 universal soft starter.
      So I bypassed the built in soft start circuit in my router and ordered a GS11.
      It worked great out of the box not only on the router but everything else in the shop that I could think to plug into it.
      As an electrical engineer I could not help but to open it up and take a look at it's construction and I was happy to find it very well laid out on a high quality PC board with quality components. Also, I saw that many of the power handling components are very robust and many are even overrated for their function.
      The thing may well outlive me.

      no more blown breakers

      I share my workshop breaker with a few other rooms and got tired of resetting and turning off other high current devices every time I started my table saw or air compressor. This soft starter did the trick.

      Review of soft starter

      I’m liking it so far. It does what it’s advertised to do. I haven’t had it long enough to really get to know it. I don’t like all the emails asking me to review it. They start as soon as you get the product.

      Solved our problem

      5 stars. We live off the grid on a solar powered battery system and we wish we had known about this minor miracle years ago. No more household shut downs when the water pump kicks in. Highly recommend.
