I read a post from Jeso on Vapor Talk that I thought was interesting about the Joker. Depending how you look at the Joker, it is really a 6 volt mod. There's no 5 volt regulator in it. So it is really no different than any other mod that uses 3 volt LiFePO4s like the Prodigy V3.
Joker Volts - Vapor Talk E Cig ForumYes, unloaded the Jokers voltage reads 6.5 volts with fresh batteries.
After all considerations while designing it, the loaded voltage and power is the crucial element.
A 510 atty measures 5.1 volts and a 801 atty measures 5.3 to 5.5 volts under load.
A zener diode is used for power surges and in rush current when turned on.
That is the reason why 3 volt LiFePO4s are used because they will supply power without
loses from resistors or a regulator, and thus the unit can last much longer with a set of batteries.
For short circuits a device is used to shut down the unit. if 2 amps or greater is being drawn
from a atty or carto, the unit will shut down after 5-10 seconds depending on how much greater than
2 amps is being used. It will automatically shut down within milliseconds if the unit draws 4 amps or greater.
I hope I was able to answer your questions.
Best Regards
Jeso
