I have been selling stun guns and other self defense products on my website, Stun Gun Supply, since 2005. In the early years, stun guns were typically of a rectangular shape with some contouring in the shape. All contained two electrodes on top and a battery compartment on the back or side. Typically one to three 9-volt batteries would power the devises depending on the power output. Claimed voltages were 80,000 to 300,000 volts.
A few years later, the first "minis" were introduced. These were also rectangular but with no contouring and quite small, about the size of a pack of cigarettes. Everything was smaller on these units, the electrodes, the power switch and the activation button. They were still easy to operate however and sales skyrocketed.
These units were too small for 9 volt batteries so they were designed for the smaller CR-123A lithium batteries. These provide longer life although a lithium battery cost more than an alkaline.
Surprisingly, these compact units produce high voltages for their size, first 350,000 volts and soon thereafter 950,000 volts. Soon, design enhancements enabled these mini devices to produce millions of volts, or so their makers claimed. (Power outputs are difficult to obtain and the voltage draws down when in contact with a person.)
Almost every new model stun gun introduced in the last couple years has featured a rechargeable battery pack (non-replaceable type). Advances in battery pack design allow high power and low weight, two positive attributes for small carry-along stunning devices. The Streetwise Small Fry series is so small that one can be hidden in the palm of the hand thus allowing the element of surprise in any counter attack.
All rechargeable compacts used to come with a charging cord. The problem with this is that they are easy to misplace. Without it, your stun gun will soon lose its charge with no way to re-charge without purchasing another cord. To solve this problem, makers have introduced units with integrated male plugs that swing out. So to re-charge you just plug the whole unit into the wall outlet.
Customers frequently ask me how long to charge the battery until full and then how long until a re-charge. I urge customers to read the insert that came with the unit. Charging times vary by model type. After the initial charge, unplug the unit. Most are not meant for a trickle charge and over-charging could damage the device.
Most battery packs are of the Nickel-Cadmium (Ni-Cd) type. These offer long life and will take hundreds of re-charge cycles. As far as re-charging goes, I recommend giving a short shock burst into the air every month or so. Make sure the spark is as loud and strong as when you first tried it after your first full charge. If not, re-charge.
Some deluxe compacts are now shipping with the new Nickel-Metal Hydride (NiMH) rechargeable batteries. These are longer lasting per charge than Ni-Cads with comparable self discharge rates. The Streetwise Small Fry series, among others, contains this newest premium battery pack.
Stun guns represent a non-lethal deterrent to intruder crime, whether it's at home or outside. The good news is that the overall trend in stun guns is more power, more choices and stable prices.
