new provari owner - all cartos giving e1 and e2 errors after 5 minutes of use

[jwark]

Not understanding this error. I'm running a 2 ohm carto at 4 volts and it's throwing this error. It happens on different brands and different ohms. It feels like my provari is defective. I can put the same 2 ohm carto on another mod, pump it up to 6 volts, and it fires fine.

Anyone have any advice? I'm not sure why when the carto is new it works for 5 minutes then just completely stops working every single time.

I'd contact them, sounds like something is funky.

What does it say as far as the ohms/resistance of the cartos?

 

[adeline]

What brand cartos are they?
Are you running single or dual coil cartos?
Are you checking the resistance on your ProVari when you attach the carto, and then later when it stops working?

Found a couple threads where folks saw their ohms dropping inexplicably.
It could also just be a bad carto. What other mod are you running it at 6 volts? It might not have the same protections as the ProVari.

I've tried those smoktech dual coil ones and boges single coil. ohms ranging from 1.5 to 3.0. I checked the ohms and it lowered maybe .1 but that's it.

If I can't run 4 volts at 1.9 ohms then that is not really good for me. That is my sweet spot.

 

[Thompson]

It can do it, but the cause still seems rather unclear, especially as they vape on other devices.

There customer support is supposed to be absolute top notch, though I've not had the pleasure (displeasure?) of contacting them.

I believe I have figured it out, they are using this chart:

I really don't like that chart. Not happy. All my other mods don't seem to go by that and they work fine.

I contacted provape though. I guess I'll see what they say.

That's only about 2.1 amps, well below the limit of the v2.

Contact ProVape.

I don't believe they are using that chart, I am running 1.9ohms on my mini/zap at 4v with occasional bumps up to 4.5v with no error. The only time I have seen an error is 5.6+ on a 1.5ohm. I think you have a customer support issue.

They aren't using a chart. I don't even understand how you came to that conclusion.

Clean all the contacts and don't screw it on super tight, if that doesn't fix it, put a ticket in.

Hm? Not according to that chart provape links to on their website.

Um, they state they are on their website.

That's a recommended voltage guide, found many places. It's very subjective (to taste) and has nothing to do with the ProVari.

If you want a "chart" about ProVari limits, try this one:

[adeline]

Um, they state they are on their website.

Where does it say that the ProVari is based on that chart? I'd like to see it, since amp limits aren't based on a chart, and has nothing to do with the function of the ProVari.

Like I said, it's a recommended voltage guide.

consult this safe vaping chart which shows the best voltage settings to use for whatever resistance your atty/carto may be

NOT

These are the limits of the ProVari.

That chart is not made by ProVape, and I have no idea the original origins of it. But newbies refer to it to figure out where to start with voltage settings.


The rest of the page is very enlightening though, did you read all of it?

Also, please note that resistance will drop in a cart or atty when it heats up, runs dry or gets old. If the cart is getting too hot, the resistance will drop and that will increase the wattage output, possibly into a dangerous level which will cause the ProVari to shut down and throw an error. This is one reason why you need to keep the carts moist as the liquid acts as a coolant for the heating element.

The ProVari can handle up to 14.5 watts. However, if the resistance drops and the voltage stays the same, the watts also increase.

For example: a 2.0 ohm cart at 5v runs at 12.5 watts of energy. If the cart's resistance drops to 1.5 ohms as its getting heated (which is very easy and possible to do), the watts suddenly increase to 16.67 which is more than the ProVari can handle so it will throw an error.

Most of those voltage guides are based off of outdated guides from 4 year ago anyway. Adeline is right.

Baditude has a much more accurate guide posted on his blogs.

In general, you dont even need a guide.

Just take the resistance of your atomizer/clearo/carto etc and add 2.

2ohms plus 2 equals 4 volts. This is about 8 watts or so.

Try to unscrewing the end cap and leaving the battery out for a few minutes.

If it persists send an email to Provape.

 

[Nomoreash]

The issue you've described isn't caused by the amp limit, that is if it's functioning properly. I've vaped over 4 volts on at 1.2 ohms with it. Try the things already recommended and make sure you're using an IMR battery, if you aren't that would totally explain it as the battery is the limiting factor.

If you've tried everything and are using an IMR then contact Provape.

This. I kept getting those codes at first too, turns out it was a little bit of juice on the ProVape contact. It still happens once in a while, particularly after I fill and replace my Nova.

 

[Thompson]

They'll behave very funny if there is any gunk on the inner positive contact, or on the threads of the base cap too.

Side note but they don't really take into account wire gauge or delivery system. While some of that info is very appropriate for cartomizers, its got a lesser place in the world of genesis.

Assuming no voltage drop mid vape, a ProVari should be able to fire a 1.9 ohm atty at a max of 5.6 volts and a 2.0 ohm atty at a max of 5.8 volts.
