I sent mine back and will post update after I get it back. The odd thing with the atties is that is 6V max with the battries.
Here's what you do, if you have a drip tip it's easier. Vape normally, when the light goes out, keep the button pressed and pull from mouth and listen. If it's still powered up, you will hear it sizzling. Might be faintly sizzling, but you can hear it if it's not cutting off.
I was just wonder how everyone elses Joker is holding up now? I just got home and sent an email to get mine RMA and got a response that they are offering a free upgrade for a varable regulated Joker2. Trying to decide if I want this upgrade or just get mine fixed. The email said it'd be 3-4 weeks for the upgrade. I've owned this thing for over a month and only got 6 days of use out of it.
You should get the upgrade because it will give you more voltage options. The original Joker doesn't have a 5 volt regulator in it and it is really a 6 volt mod.
You sure it's not regulated?
Yes, 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
