As long as the topic has gravitated towards MODs and External Power, I thought I'd show a couple of pictures of what I've been up to getting the most from my TET stuff. TET makes the tastiest (and healthiest) vaporizer cores, bar none. Whether I'm vaping botanicals with my T1 or Evo, and especially when I'm vaping concentrates with my DART, no other device I've ever tried produces better flavor or better efficiency of extraction. However, I'm a big fan of regulating the power to the core, while TET believes in the reliability of a totally non-electronic power source. The battery and holder and switch parts as a whole are commonly called a "mod". The mod is everything excluding the vaporizer. A "mechanical" mod has no electronics. The APEX/TET line of mods for 510 threaded atomizers was as efficient and well made as any of the best custom mech mods, and the Cera line is untouched by anyone else. State of the art materials and a low resistance wholly mechanical mod. Still, I like my hits to be the same from the first hit off a freshly charged battery to the last, so I prefer an electronic mod.
Meanwhile, unlike all the other crazies here (and I mean that in the best possible way, and I include myself in that group), I decided to wait to order from the Cera line until TET had their production in order, had figured out the finer details, and had a TET-to-510 adapter available. I think they're pretty much there now, except for the adapter, so if I can talk OF or Pipes or someone else into making me an adapter to screw a TET Cera core into a 510 connector, I'll probably be ordering a Ti EO core in a couple of weeks. And maybe a LL core as well. I already have everything else waiting patiently for it. I have the official TET glass mouthpiece (not the GoG adapter, the actual mouthpiece version), and a box full of CGR18650CH batteries.
I'm going to put the Cera cores on this:
It's a beautiful custom made wood mod. It takes TWO 18650 batteries. It has a 95% efficient regulator. It will provide up to 20 Watts of power to an atomizer. (The Cera line takes between 14 Watts and 16 Watts, as I recall, depending on which core). It is guarantied to drive a 1.0Ω load, but has been reported to work just fine with a 0.8Ω load. (This means I probably won't have to talk Tim into custom winding me a special core). It feels nice. It smells nice.
In the picture it's currently pumping 20 Watts into a TET SV Evo core, which is surrounded by modified TET Delrin heat shield, and has a long TET Delrin mouthpiece with a UFO in the end. It's really a wonderful thing. 13.5 Watt hours instead of 3 Watt hours (in the T1 mod, not the Cera mod) = 4.5 times the run time compared to my T1. When I get the Cera core on it, it'll have twice the run time of a Cera mod, which only uses one 18650, and 9 times the current run time of my Evo on a T1.
It
is pretty big though. And not every TET core needs 20 Watts, so for my DARTS I've taken to using this other custom made wood mod:
It's a rectangular version of a "tube" mod. It fits in the hand wonderfully, and feels great. I enjoy holding (and using) this mod more than any of my other mods. Just picking it up brings a smile to my face. It's only 12 Watts, which isn't enough for a T1 or Evo or Cera core, but it is enough for a DART/Revo core. It doesn't have the readouts the bigger one has, it has a single tiny button that you can press up, down, left, right, or in to fire the thing, and you have to adjust the wattage you want using a trimmer inside (so you really should have an inline 510 voltmeter), but once you adjust it to your liking you don't usually need to adjust it again. I like vaping most concentrates at 9 Watts with the DART core, and one of the nice things about this mod (and the big one above) is that you don't have to change any settings when switching from a LV TET core to a SV TET core. Since the regulator is set to provide a given Wattage (not voltage), when you change cores, it automatically adjusts the voltage to supply whatever power you've dialed in.
Here's another picture so you can get a sense of the size of things. It shows the two wood Mods behind a TET UltraLite, a TET Ultra, and a TET T1 base.
