Thanks for all of the info i really appreciate it! What kind of cable did you wind up using for that? Is there a DC 2.5mm plug in the back? I'm not able to find any DC cables that would work on the screw posts, nor do I know how that would work without having a ground connection somewhere in there.@Enialis
I have the Tekpower TP1502 1.5v-15v 2a power supply. It is used for tattoo machine thingies, except when we use it for powering our Underdogs. That one says HY, but it looks exactly like mine and I think that's about what I paid for it ($35). I don't know what the difference between TP and HY is, couldn't even find it on the manufacturer's website. There is another on Amazon that says TP1502 but it has fire painted on it. Bright yellow with red flames. Don't need that on my coffee table LOL! Plus you pay a premium price for those flames ($50).
Underdog pointed me at the proper cord for it, I don't remember where I got it but it had banana clips for plugging into the VVPS and the right connector on the other end for the vape.
I keep it on my coffee table 24/7, with my Dog Pen sitting on top of it. Currently I am keeping my Alpha plugged into that, and I have my SC3+ plugged into one of the UD VVPS. Both of these devices are a little fiddly getting them set, though I have found that the Tekpower pretty much stays where you set it but the UD VVPS takes a few minutes to settle. So I turn it on, turn it up, and then adjust. I turn it off when not using it so as to save the wood on the SC3+. It's a twig type vape (wood is thinner) and it is so beautiful, I just want it to last forever LOL! Or at least longer than me.
Is the suspected "bad circuit" your whole house? You said something about having to take it to a relative's house to check out the VVPS. I wonder if you could plug it in to a UPS (if you have one) to condition the line a bit? That would be a battery backup UPS. It only draws 2a max, I THINK that would be OK, Underdog would probably know for sure. It would need to be a battery backup as you want to condition the line, not just stop power surges. Unless your power is REALLY REALLY bad, a battery backup should handle the line drops and brownouts. Assuming you have grounded outlets.
I read where you are turning the VVPS up to over 12v, I promise you, no UD ever NEEDS to go that high, but if you aren't getting reliable power out of the wall, that could be reducing the efficiency of your VVPS.
Don't get mad at me, I'm not trying to be "condescending" or anything and I don't know if I've already said this to you before, if I have I have forgotten so forbear please.
I really don't get why some of the folks couldn't get these to work for them, but there has to be some difference in expectations that is going by the wayside. I think at least one issue (in addition to UDs observations) is as @SquirrelMaster said above, GROUP SESSIONS. I don't know who would think a log vape is ever the right tool for group sessions, it is patently not, so if that is what some of those folks were looking for then yes, they were BOUND to be disappointed.
Although - that makes me wonder - is there method to @tom battleboar 's madness? Perhaps he has 17 vaccinated friends who are coming over for a group session? LOL! (JK, I thought he was joking about how many he bought until he posted that picture of his pack)
Personally I'm using even less herb than I used to, since I created Frankenstem the glass one-hitter. And I wasn't using that much before. Yet I am vaping more frequently. Because each load is freaking TINY LOL! If I wanted to, I could load up the alpha glass direct draw stem with the fine screen and my finely ground "shake" and probably kill myself (more or less), but I prefer something slightly less volcanic LOL! But this way I never overshoot and only medicate when I feel like it, and I only "slip over" into stoned-ness when I actually intend to.
I did see some that were ~$45 that were traditional low end bench power supplies but they all had a dedicated DC jack on either the front or the back, so maybe you could clarify how exactly that hooks up if you know the technical details or maybe even a picture of what the screw post to DC jack cable looks? I'm curious as to where the ground is in that connection.
Yes, the suspected "bad circuit" is basically my whole house, I am already running everything through either a conditioned bench supply or UPS because of how much noise there is in the circuit. Since I set all of that up we have had everything but the wiring in the walls and outlets replaced but it hasn't really solved any of the problems with my more sensitive electronics so I'm still looking for a solution.
The issues with the underdog either under or over performing because of fluctuating voltage were on the UPS actually not one of the unconditioned lines.
But yea my power was dangerously, code violatingly bad until very recently most of the wiring and outlets are still from that so I know that this isn't necessarily an issue with the underdog per se.
I've run it as low as 11.5v but I can't achieve full extraction at that temperature without having to turn back up to 12.3v to get the last two hits. Its not like it doesn't work at 12v either, it's just hard to dial in specific temps on the stock vvps so I leave it at 12.3v.
The in line vvps I saw had double digits after the decimal point for better accuracy but they all seem low quality and like they might suffer the same issues as the stock one. The bench supplies I saw though were twice the size of the one you linked and I would like something smaller for my UD.
I actually need another bench supply anyway so I don't mind getting something more expensive even if its overkill, especially if it let's me use multiple devices at once, but the UD is my small out of the way vape for my workbench because my other vapes take up to much space so keeping the footprint small and being able to leave it plugged in while working are very important.
Any thoughts? I don't want to start ranting out loud about potential options if you think you know of a better solution. The footprint of the vvps you linked has the same sized footprint as a full featured vvps so if the in-line vvps like the default aren't a good option I would probably want to get something that was multipurpose if its going to live on my electronics bench.
