Most of my friends who were going to be engineers in college became doctors because it was a lot easier, that being said it's a simple concept. .. capacitor is required to get more power than the battery can supply.

Seems like I recall that my Provari could go up to like 6V, but had a rather low amperage limitation so you couldn't get decent wattage out of it.
You are absolutely correct in what you are saying, but you do see my point I think. I can build for a fresh battery charge to produce the flavor I prefer, but it only last a very short time, requiring me to tote a pocket full of fully charged batteries and to change them to frequently to stay where my juice taste good to me. This I know as fact, maybe not the electrical theory behind it 
Yeah I gotcha , don't be sorry I was thinking that the newer chips would have caps, or something equivalent, incorporated into them, that's what got me excited in the first place. What it really comes down to is the amp limit, like you said on the prrvari. That's why the dna40 was killer when it came out, killer is the wrong word...lol. but it has a relatively high amp limit.
I'd like to run liposuction in a mech configuration, but replaceable I haven't spent a lot of time looking but they are pretty cheap for what I've seen briefly, and have nice high specs. Is everyone generally scared to use a lipo pack or are they just not a fan of the slow charging with on board chargers....?

i ain't skeered, I'm to stupid to be skeered Pretty sure I charge them all the time for my GoPro, phone, quad copter etc ......
Pretty sure I charge them all the time for my GoPro, phone, quad copter etc ......Not quite. True you can't get more power, but you can trade current for voltage. Same power, but higher voltage.
That's what a boost circuit does.
Say at 4V you can pull 20A. You could convert that to 10A at 8V. Same power (80W). Granted the conversion isn't 100% efficient.
Now, since Ohms Law dictates current is a function of voltage and resistance, and since resistance is fixed (by the coil) to increase current in the load you need a higher voltage.
No readily available charger for lipo, they are generally hardwired in an have built in chargers(of dubious quality), and generally get power via USB (occasionally a different DC source).
There is no standard packaging (just look at all the different packages for cell phones) so no universal chargers.
You have to pick a cell, possibly attach connectors, then supply/sell them. Then users need a hobby charger with leads to attach to the battery.
Or you find an existing pack (like a cellphone or power tool) that can be reliably sourced from a quality vendor (no low quality "compatible" batteries) that has an available external charger.
Seen any recently for cellphones? I haven't as they have been trending to "not user replaceable" and people just weren't buying the ones that existed.
I'm thinking like hobby lobby type shrink wrapped cells w/leads and little connector ... I have melted some connectors on rc cars now that I think about it, I've unsoldiered batteries that were soldiered in...hmmm.
Most of the chips are in the high 90`s as far as efficacy goes right? What do you think about these boards and lipos anyways...?
The modules of today use pulse width modulation which essentially chops the flat dc signal turning it into ac with a sine wave and draws off of the peaks and valleys of the waveform. After the correct voltage is reached I is filtered by a series of small capacitors to essentially fill in the blanks of the rectified Dc wave form which yields a pulsed Dc waveform at a higher voltage than the battery can supply. This principle is actually used in a lot of our everyday appliances. The microwave would be a prime example. Led flashlights as well.
Most led flashlights must have 5v and alot of current to fire most of the higher grade led flashlights. Most of those flashlights use 18650 batteries in parallel giving them an output voltage of 3.7-4.2v but the od actually needs 5v or more PWM to the rescue. Most of the tech used in the world of ecigs stems from the flashlight industry, I believe this is a big part of the reason most ecig boards until the Dna 30 were limited at 6v and 13.5 watts. There is simply no need to push an led beyond 6v.
Now we are seeing purpose built boards for ecigs which will be great I suppose but we are still in the early stages of this, I would imagine in the next few years the boards will top out around 250w and be smaller and more reliable. The sx350j is a big step in this direction. Also the reason I don't really like the Evolv/Dna principle of only raising the bar after they have cashed in on the current level. All they're doing is slowing down technology which will work for a while until they get run over by a company that evolves with the tech instead of standing in its way. Greed only gets you so far in this world eventually you need to overcome and adapt or get out of the way. Evolv whom refuses to Evolve (see what I did there) will be a will be nothing more than an ECig history lesson in the next few years if they don't Shiite or get off the pot. YiHi seems more than happy to Evolve with the technology, it's sad that the American company can't keep up solely due to greed. Step it up or step aside.

Yeah, nah. I'm a mech guy.
No vape mail today other than ft derringers which shipped the day after my tmod lol
It's ok and all. But the lack of tmod mail is starting to physically hurt... hopefully tomorrow

You gotta be ....ting me, ft made it faster than the fastest option I could buy from the USPS! ?!? Dammmn. Maybe it got lost? Should I call the pay office and ask them about making an insurance claim? I bet if anything is gonna huey it along that will. .
usps is taking forever all around, it's probably gone via dubai or something. my peko prints have been sitting motionless at the airport for 6 days now
Pretty close as far as I read.
Though the wave is a square one and the current is still DC.
Alternating current changes direction and thus can be read as going from pos to neg and back in one cycle or hert(z).
DC (direct current) doesn't change polarity.
The square wave in this instance is merely representative of a switch turning off and on so many times per second (frequency or hertz).
A sine wave is representative of a motor being spun to make electricity.

The cellphone batteries have a low "c" rating which determines the safe amp output of the cell(s).
You're gonna want something very similar to this LiPo 2000 2-cell 7.4v Battery Pack, LiPo 2000mah Packs, Lipo-2000-74-Pack
Almost the same length as a 18650 and 100c rated
