Post 1 of 4:
OK, for anyone looking for more scope pics (zoidMan) than I already posted earlier, here are the screen caps from my TPI Scope Plus 440 software (found it). The software doesn't have a cursor mode and readout so I still don't know if it's a Vavg or Vrms reading (and really don't care after you see my conclusions).
Regardless of whether it bucks, boosts, buck-boosts, it vapes well for me and it
most certainly does reduce power below battery volts.
Do the math. 4.2 volts through 2.1 ohms = 2.0 amps, 8.4 watts. At 4.0 volts it's 1.9 amps and 7.62 watts.
In the readings below 2 were from an iStick fresh off of overnight charge. Now do the math with these figures. Also my Radio Shack 22-168 DMM on the same setup read 3.1 volts and 1.46 amps.
Any figure you use indicates a reduction of "power" with a fully charged battery.
My interesting conclusion is this- after you look just at the iStick numbers and have a look at the other device numbers, which ones match up to what most of us use as daily vaping measurements.. (Meaning volts based on your experience and/or coil ohms, or watts based on your vape preferences. Then when you want to compare things, some of us do calculations based on ohm's and watt's laws, or ask other vapers right?) Well,
none of the devices I measured are really that close to the results you get using ohms/watts laws. Even using the scope or the DMM
numbers.
No repeatability a problem? No "standard"?? Who cares. How does it compare to YOUR other stuff, and YOUR measuring device ... and how does it
vape for YOU??
This thread is way too fast & furious to keep up with so I'm just going to leave everyone with the pics, my conclusions, and reiterate that (imo) the iStick
most certainly does reduce "power" below battery volts. Enough for YOU? Can't answer that!
I can only post 5 attachments in one post, so since each device I measured has a volt and an amp pic, I'm doing them in sets of 4 and hopefully I'll get all the pics in successive posts.
Vape on, Vape happy!
