There is a VTC Mini 60w and a VTC Mini 75w. Is it the same device, but the 75w has newer firmware? The one I sold my friend was a 75w. I know all you have to do is connect it to a computer, but I've been told by more than 1 person in the security industry to not do that. Not sure at this point if I even care, since I'm a low wattage vaper.
To understand this one you need to understand Watts law. If the manufacturer allows higher max watts they need to increase the cutoff voltage to protect the battery so you're battery has less endurance. I never go above 30 watts. I wish all my devices could be firmware downgraded to that in return for a higher voltage cutoff. The high watts ratings are kids stuff and cost you battery time.

The Pico is my favorite form factor. I'm stockpiling them. I'm gentle with mine. Has anyone noticed any thing about the design that might limit their service life?

You mean other than the very poorly designed threads on the battery cap.....Then no.
I have to watch it every time I change a battery to make sure not to cross-thread the cap.

For the love of God! I'm so going to start a thread on this because I'm so tired of this! It's "Ohm's law"!!!! Please, look it up!

I understand exactly what you meant, but reading that literally, it's really not right. Having a device that is capable of high wattage and then using it at a lower wattage is actually likely to gain you battery time, especially if the device takes additional batteries in order to achieve its theoretical maximum. You are going to get way more battery life vaping 30W on a 200W mod than 30W on a 30W mod.

But I understand you were talking about using those higher wattages. In any case, referring to it as "kid's stuff" really harms your credibility a bit IMO. Certainly everyone here on this forum is an adult, whether or not you think so, and certainly lots of those adults enjoy using that kid stuff. Just my 2c.

Ohm's law, strictly speaking, states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship.
I=V/R

It's not about power.

Are we sure the voltage cutoff was raised with the 75 watt firmware update?

That would decrease overall vape time as the battery drained down regardless of ohms law. If like me you are a fairly low wattage user (35w in TC mode), not sure how big a time difference one might see. Identical battery runtime tests would have to be done to prove any noticeable difference.

The cutoff voltage is programmed into the device by the manufacturer. The lower the voltage the more amps are required to deliver the watts set by the user. The batteries have safe amp limits specified by the maker of the battery. The higher the watts allowed by the device the higher the volt cutoff will be to prevent the amps drawn from exceeding a value, like 25 amps. If you are going to fire a pico at 75 watts it's important to use only 25 amp batteries. I never go above 30 watts so a 20 amp battery won't be challenged.

A two battery mod wired in series won't give more endurance at low watts. I compared a VTC mini and cuboid which use the same board with puff timer. The mini puff time was slightly longer at my low voltage setting than the cuboid using the same pair of brand new batteries. The cuboid lives in a drawer. If the batteries are wired in paralell the run time will be longer. There is no benefit to a mod that allows higher watts than what you actually use.

A two-battery regulated device, parallel or series - doesn't matter, should provide roughly double the battery time as a single-battery device (Watt setting being the same, and using the same batteries). If not, there's an issue with the chip efficiency. And I've heard nothing about the voltage cutoff on the Evic having been made higher with the 75w upgrade, nor have I experienced it in practice (the batteries still discharge to about 3.2v).

I am about to buy some wire, and I was looking on amazon as well.
One quick question. (hopefully this isn't too far off topic, it wasn't worth a new thread to ask.)
But the amazon link I am looking at says resistance wire, and the temco link says non-resistance wire. Is there any difference? I would think you would want resistance in the wire?


short answer : I don't know... :unsure: :blush:

my beliefs : all wire HAS resistance, but because of the blend of many metals, one can be very low (non-resistance) manufacturer makes determination ?
so I can not give an explaination... (I got nothing) o_O

I skimmed 'MY' wire roll collection, and IF it said which, they all said resistance wire (some didn't say)


:evil:

Thanks. I just went ahead and ordered one from Amazon, I had a lot of other stuff in that order anyway. Next time I'll try temco, considering they are cheaper and have free shipping. (the resistance vs non-resistance kinda stumped me??)

** so did ya'll talk about this and I MISSED IT ?? :blush:
just ran across it and can't/don't remember any mention of it...

View attachment 600421

I'm not into 'sqwankin', just dig new gear... ;)

Been mentioned, but it's been a long wait since it's was announced over a month ago. Still not shipping yet. :mad:
