Highest Amperage Stun Gun

Highest Amperage Stun Guns

If you’re looking for the highest amperage stun gun, then you’ve seen past the hype concerning voltage. When we first started selling stun guns back in 2000, the highest voltage stun gun at the time was a whopping 300,000 volts.

Soon after, manufacturers started to increase the stated number of volts to be higher than the next guy. Amperage wasn’t even on the radar. We had 400,000 then 500,000 and even a 775,000-volt stun gun. It wasn’t long till the Million volter came out and it was all the rage.

High Voltage Stun Guns

9 volt stun gun batteryBack then, these devices worked on 9-volt batteries. Any reasonably common-sense type person could deduce that the more batteries it took, the more powerful the output actually was. This was true no matter what the stated voltage was. If a device took two batteries and was 300K volts, it was more powerful than a million-volt stunner that only took a single battery.

Comparing them side by side was another way to tell the difference between them. You can tell how strong it is when you fire them off one after the other. Without knowing any specifications, your eyes and ears will tell you exactly which one you don't want to be stunned with.

So even after the 2nd and 3rd million volters came out, there wasn't much difference in the actual output of any of them. While higher voltage means it has more penetrating power, the newer numbers coming out were more for marketing than any increase in actual electrical power. Voltage as low as 25,000 is enough to go through clothing, so higher amounts are unnecessary anyway.

Is it Volts or Amps?

In any case, it's the amps that provide the juice delivering the most energy rather than the voltage. Voltage gives it the wide open push to go through clothing, so the higher the real voltage, the better the ability to deliver the charge through thick jackets and such. Amperage is the biting force.

And in the case of stun devices, we're talking thousandths of an amp, measured as milliamps. You've heard the saying, "One amp will kill ya." Well, we're nowhere close to that when dealing with these self defense products.

Stun Gun Schematic

Most of them are between 3 and 4.9 milliamps. This amount is enough to deliver the effect you’re after. Anything over five milliamps can overload the circuitry inside the device and burn out the capacitor. The capacitor is where the energy builds up and is stored until it's discharged through the probes. Too many milliamps and you'll burn out the unit.

One of our strongest stun guns is the Runt. It has 4.5 milliamps which are more than enough to overload the electrical impulses of the human body. The body has nerves just about everywhere so anywhere you touch the person with the probes of the stunner is going to have an effect. However, if possible, you want to go for the major muscle groups such as the neck, upper body, or even groin area to have the best effect.

The electronics inside the Runt are top quality and the thick electrodes (probes) on top deliver all available energy into your attacker. For being such a small weapon, it really does have it all when it comes to available power and having the desired effect of stopping an attacker.

Nowadays, most stun guns use rechargeable batteries. This saves you from having to replace batteries, but you do have to remember to plug in your device every 2-3 months.

The stun gun is one of the most powerful and effective tools for self defense. Handy, simple in design, and straightforward to use, stun guns are preferred in many instances for deterring an attack or controlling unruly and dangerous behavior because it delivers fast efficient results. Stun guns come in a variety of power, usually expressed in voltages. The number indicated as the voltage of the stun gun is an indication of its power, but again, it's the amps that matter.

Stun guns with high voltages are intended for close encounters. They are designed to shock by contracting the muscles and causing pain. However, they may not be effective in knocking the assailant to the ground. They are, however, quite efficient at producing a shock that will cause enough pain and discomfort in order to discourage a physical attack.

Just how powerful is stun gun voltage?

If you’ve ever experienced the discomfort of static electricity, such as when you rub your shoes against a synthetic rug and proceed to touch a door knob, then you could safely say that you’ve been shocked with about 20,000 to 30,000 volts of electricity. This does not even compare to what a stunning device gives.


um, I am a licensed ham radio operator and also have a bit of an electrical/electronics education.

to sum up: at sea level given 100% humidity, the dielectric breakdown voltage of air is 10KV at 1 inch of Separation. Dryer air will have higher breakdown values. Now, if you can deliver 10 ma at 10kv over that inch, that will be about 100 watts of energy delivered over the approximate 10 Microseconds the pulse lasts. This is a realistic value. In order to pull 100 watts from a 9 volt batter, you would need to draw about 11 amps over 10 Microseconds. This is doable but the battery will not last very long. Most alkaline batteries will provide about 5 pulses before they effectively die. Rechargables (such as NiCAD, Li-ion or LIPO and lead acid) can deliver much more current and will tend to last a bit longer under full load.

Now, 10 KV will easily go through air or even through skin, but is effectively stopped by thick clothing (such as heavy leather). Now, between the laws of conservation, etc, accounting for losses, what you get out of the battery in terms of watts will be what you produce at the output. A suitable voltage and current for being able to deal with typical scenarios should be no more than 50 KV with 1 to 1.5 inch probe separation and at most about 25 MA max. However, since most batteries cannot produce that level of wattage, even over 10 Microseconds, an oscillator and high voltage capacitor are needed. The oscillator will feed a high voltage transformer to charge the cap. When it reaches full charge, it will discharge across the probes. btw, at 50KV and 25ma, you will still need approximately 12.4 KW. over 10 Microseconds. Since almost no small battery can deliver this it takes a bit of time to build up the level needed, which is why most stun devices can produce between 4 and 6 pulses per second. Of course, more batteries means more capability to deliver said wattage, but the key here is the high voltage cap. For reference, I have a 100 mw HeNe laser here with a 50,000 microfarad mylar cap rated at 50 KV. At full charge on that cap, the discharge would be enough to kill a full grown man instantly on contact with the skin in 3 vital areas. Most stun devices don't use a cap that big. so, voltage and current are often necessarily limited. Since the main power source is the limiting factor here, you are pretty much stuck with 5 ma and 50 KV at most. That is still effective enough to drop a full grown man..

btw, there is one poster on here who is a qualified electrical engineer and what he says can be taken as gospel. Ohms law, the law of conservation of energy and any other applicable physical laws apply and there is no bending them or violating them.


They say that with the Stun Gun you need 1 microcoulomb or greater to have it be very painful/ unbearable.
so 1uC OR 1/1,000,000 of an amp x 1 Second
This also depends on the subject and where they get hit.
Big difference if you hit someone on the palm or if you stick it right behind the earlobe and vertically down the neck.

The STUN GUN is NOT measured in Voltage but Coulombs.
Technically it is supposed to be measure in Coulombs which is just a unit to measure charge like ampere-hours or milliamp-hours.
A Coulomb is how much charge flows in 1 second- it being
1 Ampere of Current X 1 Second.
So think of it as all the charge that flowed for a second.

This is why if you are looking at a Stun gun the Voltage number is BS when it says Hundreds or millions of volts.

As far as the 30,000V jumping a 1cm gap you guys need to refer to what is known as Paschen's law. Basically it is the math that describes the voltage needed to make the arc between 2 distances. This 30K volts everyone is talking about can change with variables such as Pressure or if it is in a vacuum.
So I believe the 1cm arc requires almost 30K volts
but a 2cm spacing needs only 50K to arc
What the issue is at a certain distance (far) it requires great voltage as you get closer and closer there is a spot where instead of needing less voltage the number increases again before it then decreases again.

These are estimates on the Voltage Required Not sure if accurate been a long time on this

Distances are in cm centimeters
Distance(cm) ---- Voltage /(arc)
0.5cm--15K Volts
0.75---22K Volts
13.00(1/2in) 300K
65 METERS - 97,500,000(97.5 Million V)
A typical lightning flash is about 300 million Volts and about 30,000 Amps


They can't be above $30,000 or 30 KV because that is the breakdown of air and a 1 cm spark gap anymore and you're violating the laws of physics, I wish that stun gun manufacturers would stop lying about this.

Could be wrong but if you have a million,a billion, or a zillion volts it will pass. Once it arcs, just like as if it was a physical copper wire, It will pass any voltage that is being transmitted.

There is no step down transformer between the electrodes.

Air is an insulator. You just have to increase voltage til it excesses the insulation value. If you take a copper wire with 120 volts but use wire rated for 1 volt insulation, odds are you will get a tingle because you exceeded the insulation rating.

I think what he is trying to say is it takes a MINIMUM of 30,000 volts to make the jump.


So I have a 500,000V stun gun and I just put two 3,300 MA batteries in it and it works pretty good from the sound. is that too much? Is it potentially deadly? It hasn't burnt out the circuit so I'm wondering if its even delivering more power

The phrase "It's the amps that kill, not the voltage", is extremely false and misleading. If I lead to you a 450KV high voltage transformer line, would you want to touch it? Of course you wouldn't. We know from Ohm's law that V = I*R or Voltage = Current * Resistance. If you put a lot of voltage across your body, you're going to feel it cause if you divide the voltage by the resistance of the body, you'll get the current that flows. Sure, it may only take a few milliamps across the body for you to feel pain, but you need a lot of voltage for that. If the more voltage you apply to an object of a fixed resistance, the more pain you will feel. Yes, amps are a measure of how much current runs through the body, but you couldn't have that current without a substantial amount of voltage.


I have to admit that I had a stun gun that took 2 9 volt battery’s back in the day and it had a curve to it to get a better angle on the person so anyway there was two very large guys that was drunk and they tried to attack me and they was both wearing LEATHER jackets so I hit/stung one in the rib area and low behold that sucker was on his way down if not for his buddy to grab his other arm like from under his arm pit to stop him from going down and the guy was literally ennobled and the guy that was holding him was yelling at me to stop stop stop lol cause he could’ve heard that gun blast away and it saved my ass I really wish I knew what happened to it or would of like to know what was it like I don’t remember nothing about it but just what I typed but to answer everyone’s question I knkw for a fact they go through leather jacket lol


Amps= The Current Flow Per Second. Volts=The Pressure of the Current. That is what I know, put simply. Lastly, The Two Combined, Equal Total Power/Watts i.e. Potential Electrical Force. I AM VERY DISAPPOINTED TO HEAR THAT AT ANY AMOUNT OF AMPS ABOVE 5 MILLIAMPERES THE CAPACITOR WILL MALFUNCTION/BREAK... I WAS PARTICULARLY LOOKING FOR A 100-200 mA device, with atleast 30,000 volts.... -SIGH-.

Those of you who think 30kV is the max sent across prongs are incorrect. You can't apply ohms law because in this circuit the parts of the stun gun are ohmic but air is not ohmic.

Air doesn't really have a dielectric "resistance," but it does have a dielectric strength, which, if exceeded by enough volts, can be overcome at ANY distance. Think in your head of,..lightning, which travels, a little bit further than 1cm through air.

How much the true measure of strength! 0.5–1.0 µc = pain 1.0+ µc = intolerable pain what is the µc for this ???"

Because at that distance 30kV will break down the dielectric resistance in the air itself and arc between the prongs, thus discharging the voltage so it can build up again from scratch untill it reaches 30k (or whatever distance your progs are) this is one way you can tune into the resonant frequency a tesla coil (tuning one right now). And please don't goole this and start yapping to me about air humidity etc i just don't care....

What is the value and technical description of step-up transformer shown in schematic?

Being an electronics engineer all I can say is Bull S#!S+
Amps, as you say is the term for the curreht flowing in a circuit. That is determined by the voltage across a resistance. I=E/R Current/Amps =Voltage/Resistance.
I like your schematic but your text is bull shit.

The guy did give the mA why do you say he didn't say the amps he clearly said the volt is for penetration and amps delivers the bite. That's informally sound info I don't think anything gets through a thick leather jacket (without puncture) and have yet to it happen,

What makes you think 30k volts is the max?! The spark plugs in your car get hit with 10 times that....

And just what source are you using that states the voltage cannont exceed 30,000 volts when traveling between two prongs? Because I can't find the actual reference in the source given by Sabre. I imagine it's made up.

Actually 30,000 volts is the maximum that can be sent between two prongs 1 centimeter apart. Any more voltage would be against the laws of physics. You should really advertise the Amperage because that is what does the damage.

Thank you for, I hope, an unbiased opinion. I do not trust most reviews because they are pushed by the dollar signs, and the information you just gave sounds vert creditable. I do know the volts are a highly overrated number, and the amp number is much more important. Try getting that number. Thanks again.
