@THC SCIENTIFIC how would one go about replacing their outer shield & mouthpiece for their SR-74? Long story short, got too medicated & tossed it in the trash by accident. And the "vaporizer" has had my attention for a while now, any idea on a release date?
I don't know what the max power is that the ceramic heating rod can handle without damage but I do know that an SR71 "7.4v" rod varies between 1.5-1.7 ohms at room temperature. And for a 1.5 ohm resistance to put out 100 watts you would need 12.25 volts at 8.16 amps.what is the maximum power the sr71 7.4 rod can handle without damaging anything? i would like to try it on a 100watt mod i'm picking up for ejuice. sony vtc5 batteries will handle the 18amps or so it's gonna pull if set at the full 100 watts but how much can the herc take? it's more of a curiosity then a need. with the iris i usually only use around 28-30 watts for a good mix of flavor of vapor delivery.
I don't leave mine in all the time ( but mine mostly gets used in the car.). Might I suggest a power strip with a switch that you could place nearby. Then you can switch on when you need it. @THC SCIENTIFICIs it wise to leave the core plugged in all the time? I'm getting a bit tired of having to plug and unplug it everytime..
I've had mine plugged in for over a year, but though a UPS that runs my computer as well. My only issue is seeing it on sale for half the price I pre-ordered it forAbout the core. I have mine plugged all the time since 3 weeks, and a usb fridge running through the usb outlet. I decided that if it needed to be turned off, there would be a mention about it in the instruction manual. Or an on/off switch.

But, remember that the ceramic heater increases in resistance quite a bit as it gets hot. On my Iris I (used to ) see the resistance about 30% higher right after a hit. If the heater resistance increases to 2.2 ohms it would take about 15 volts to maintain 100 watts.
So, if it were me, I would avoid any constant wattage mode and stick with constant voltage.
Good luck. I've never heard of anyone burning out a heating rod in the Herc. You could be the first!
Hedo
maybe that was the sr74 theni don't see how. this sr71 is fairly indestructible.
My biggest gripe with W9/UpTech is the ~2 year delay (so far) for an Iris upgrade (@THC SCIENTIFIC ). I burned out my v1 Iris a few months ago (pop and burnt smell) and have had to rely on the barbaric practice of feathering the power button on my v2 top! Seems barbaric anyway after having gotten used to dialing in the power level with the Iris. Surprisingly my burnt out Iris still works to measure battery voltage and cart resistance. Just no power applied any more. If I knew how to take if apart I'd try to fix it.if it works i will be leaving the iris at home at least until the v2 is available. i'm always terrified of that thing frying (cuz it likes to do things like fire at 7.4v when i have it set to 4v) and there is no other vv/vw option from uptech to replace it with if it breaks. took me 6 months to find a used iris for sale and i paid about as much for it.
They should fit just fine. I have both the 71 and 74If I were to order an sr71, do the titanium coils from the 74 fit correctly in the 71, or should I just buy the standard coils?
