Pre Built Stun Gun Transformers

There are not many places you can get (high voltage / high power) stun gun transformers on the market today.  XRS Design Systems is the best place to find them. Simply look under their Pre Built Impulse Ignition section.

After you buy one simply put the impulse ignition unit inside a small hand held miniature enclosure of your choice to make a savage high power stun gun system. Easy !

You must be very careful of buying fakes of high voltage impulse ignition units that lack performance from China. Rule of thumb Don’t Buy China ! you will just be disappointed and waste your money.

These units shown below are fully ready to go, just connect a battery and get fast impulse power from the output probes.
