Corrected entry: Holmes' ''stun baton'' works multiple times without having to recharge. That is not how electricity works. If it has the ability to discharge, it will keep going until the charges between the device and the ground are equal, which would be after one time. And batteries that small didn't exist then.

Correction: The victim gets flung away from the device instantly, breaking the contact, so that the discharging is interrupted.
Correction: You suppose a lot knowing absolutely nothing about how this home made device of his works. A tazer can discharge multiple times without needing to recharge because it must be activated with a button press. Apparently there is a similar such activation mechanic on Holmes' baton.
