I saw this picture of the internal heating elements of the mighty. I hadn't seen it before so I wanted to share!
Pretty neat: you can see the thermocouple in the bottom left of the heating chamber to track temp, the air path spirals up the element picking up convective heat, and you can see the hottest spot is in contact with the herb bowl which gives it the conductive heating. Superbly designed device!
The greatest vaporizer. I've had mine for almost 7 years now and it still works great. I did replace the batteries a couple years ago and that made a big difference in returning the battery life to what it was like when new.
Wow, that's an impressive lifetime! What batteries do they take? I was guessing maybe Molicel 18650's? When I saw the picture I was the first thing I was thinking about.
I used Panasonic NCR18650GA 3500 mAh 10A batteries with tabs. So far they've been great.
Do you mind if I ask, how much flower do you normally load for a session?
I'm trying to find a good solution for 2 people as I don't really want to haul volcano bags outside with me.
I use the dosage caps, you can change them in seconds. I haven't used the volcano since getting the Mighty+
I believe it comes out to about .15-.16 grams per capsule. I scoop it up with the capsule and then pack a little more on top and squish it a bit with my finger. It's the perfect amount for 2 people.
How difficult was it to replace the batteries?
It wasn't too bad. Took maybe an hour to complete. You'll need to do some soldering and you'll need to rebuild the internal battery assemblies with some kapton tape. Pay particular attention to how the wires are run on the assemblies or you'll have difficulty making the case fit back on. Honestly the most difficult part was sourcing the batteries with the tabs already welded on. While I'd love having a battery tab spot welder, I just don't think I would use it enough to justify the space to keep one around.
IIRC it can be done with a bunch of 9v batteries connected together
