I received 3 Nivel chips from Russ at Click-Bang. Once I get them in a mod - one I keep, one to Russ, and one to a lucky person to win in a contest.
The retail price of the Nivel chip is $67 plus shipping and comes from Russia.
I've breadboarded and tested the first one. My initial impressions with vaping with it and testing it so far are very favorable. Totally easy peasy to get up and running with it as it comes pre-wired and needs no external components other than an LED, atty switch, and connector. That's it - zip zip lickity split and it's done.
Accessing the menu allows you to set either variable regulated voltage vaping (from 3v - 6v) or variable regulated wattage vaping (from 3W - 15W) and uses one AW IMR 18650 battery.
Just like with the DNA board, max Watts with the Nivel chip depends on the resistance of the carto/atty - the lower the resistance the higher the max; the higher the resistance the lower the max.
Measurements from various cartos/attys (max capable):
1.5 ohm DCC: max set voltage = 4.7V (loaded = 4.63V, 2.79A) ::: max set wattage = 15W (loaded = 4.78V, 3.0A)
2.5 ohm DCC: max set voltage = 6V (loaded = 5.94V, 2.23A) ::: max set wattage = 13.5W (loaded = 5.82V, 2.25A)
2.4 ohm SCC: max set voltage = 5.9V (loaded = 5.8V, 2.59A) ::: max set wattage = 15W (loaded = 5.9V, 2.54A)
3 ohm SCC: max set voltage = 6V (loaded = 5.93V, 1.9A) ::: max set wattage = 12W (loaded = 5.89V, 2.02A)
2.4 ohm Std. atty: max set voltage = 5.9V (loaded = 5.9V, 2.36A) ::: max set wattage = 14.5W (loaded = 5.8V, 2.44A)
Now for those of you who like to plug numbers into Ohms Law, you're going find various results for each of these equations:
W = I x V
W = V(squared)/R
W = I(squared) x R
I = V/R
For example - I measured the 1.5 ohm DCC and it was 1.5 ohm when I started the testing and it was 1.5 ohm when I took the measurements. For regulated wattage vaping with the Nivel preset at 15W, the volts measured 4.78V and the amps measured 3A.
W = I x V = 3 x 4.78 = 14.34W
W = V(squared)/R = (4.78x4.78)/1.5 = 15.23W
W = I(squared) x R = (3x3)x1.5 = 13.5W
I = V/R = 4.78/1.5 = 3.19A
As you can see, the calculated amps is higher than measured amps and I think that may be what's throwing the Watts equations off. Either that or sumfin is going on with resistance behind the scenes. Or both. I dunno.
And yes, I vaped with the 1.5 ohm DCC with the Nivel set at 15W and it was a mighty suh-weet vape!!
I did a video explaining the menu system (the camera didn't pick up the display very well - the display is actually very sharp and clear)...
