From the same manufacturer as the Knuckle Blaster Stun Gun, the Double Trouble Stun features two 600,000 volt stun guns for a total of 1.2 million volts of stopping power.

Did you ever wonder why a TASER® at only 50,000 volts has the increasable stopping power that it does? This happens for one reason and one reason only and that is the space between the electrical contact barbs. The greater distance between the two electrical contacts, the greater the stunning or stopping effect. Most stun guns only have 1.5 inches. The Double Trouble has 5 inches between contacts. Each side has 600,000 volts making it doubly effective and double trouble with double the stopping power at 1.2 million volts.
