if you're touching someone who gets tasered

Pepper spray requires distance-at arms' length, it's possible to spray yourself as much as your opponent. In other words, where a stun gun could be tenable is in a fight or attack where you are in contact with your assailant. Bludgeons of any kind such as batons or saps are not either…and any “pressure point” pokey thing is unlikely to do much in a real fight. Providing that yours has sufficient enough amperage (with fresh batteries) to actually induce not only pain but mild muscular contraction, a stun gun could (in theory) be an effective contact weapon. On paper, the stun gun is not an entirely useless defensive tool. But is there a possible niche? When Would A Stun Gun Be Practical? With so many downsides, you may be starting to gather that stun guns are a limited tool.

An Axon-brand X26 TASER (a common model issued to police) has an output of 2.1mA. So, an inherent flaw in stun guns is that they can't be made powerful enough to be reliably effective while remaining a non-lethal tool. To be a reliable fight stopper, you'd need to deliver enough amperage to guarantee muscle seizure, which can require anywhere from 50mA to 150mA…but the problem there is that even 100mA (0.1 amp) can be fatal. AA batteries have around 2,800mAH (milliamp hours 1 milliamp per hour for 2,800 hours) of charge, and a 3.7-volt 18650 battery has about 3,400mAH. Defibrillators, by contrast, typically have an output of around 45mA or more. Inducing mild muscular reactions can require 10mA to 30mA. Humans generally need to be subjected to 5 to 10 milliamps to even register pain. This is why humans can withstand thousands and thousands of volts with nearly no effect.

An ounce of water at incredible pressure is still only an ounce of water, but four gallons per minute is a lot of water to move regardless of the pressure. To help better understand that, consider the classic analogy that compares voltage to water pressure but amperage to water volume or flow rate.
