Thinking about my first APV, why batteries? I have unlimited power at my wall outlet.

[RavenTai]

So i have been vaping for about a month now, I have not bought a pack of analogs since my eGo-C kit arrived,

I think eGo or at least the batteries will do for my out and about vape for a while but I want something more for home, most vapes are decent with it but every once in a while I get a perfect vape from my ego, but it is fleeting, I am looking for the perfect consistent tasty vape, I want to play with dripping, various atomizers, tanks and alike, but the ego battery is limiting in what you can do.

At home I vape in one spot, the living room, really just at the computer, so why bother with the cost weight and hassle of swapping batteries into a big heavy PV that still has a limited number of amp hours before you have to charge.

A few years ago I assembled a 1 amp variable voltage DC power supply (0-24V) to power up an automotive cluster on the workbench, it was a transformer, 4 diodes forming a rectifier, a few capacitors to flatten the ripple, a IC voltage regulator, and a pot to control it, seams something like that (little more amperage & narrower voltage range) with a cord and a small wand with a 510 head would be the ideal stationary vape? inexpensive unlimited power, the power supply could be as bulky as needed its stationary, voltage displays, amp meters, guarded switches, giant dials, I doubt it would be my last APV but it could be a good way to get started.

has anyone played with this idea? any plans out there? square wave DC and PWM?

I have seen voltage regulators and current regulators but how is wattage regulation achieved?

No need to re-invent the wheel.
All you need is a passthrough and an AC/USB adapter capable of handling about a 2amp current draw.
You can get them for about $15 or so.

And dump that "C" part of your ego. Just use a regular 510 clearomizer or cartomizer. They have tanks specially made for eGos that work better than the stupid C and T systems they hang on those egos. Try a Stardust, aka CE4+, aka ego Vision Clearomizer.

Oh, and if you want variable voltage, get a VV PV capable of holding a protected Lithium Ion. Put a 3100mah battery in it and you won't be swapping batteries very often. And you won't be tethered to a power supply.

Radio shack used to have a variable voltage AC/USB adapter. I don't know if they still carry them, but someone probably still does. Then, all you would need then is a straight passthrough e-cig without an in-line battery. They're out there too and they're dirt cheap. Just don't try to plug them straight into your computer.

Wattage regulation is controlled by the resistance of your atomizer/cartomizer.

I just noticed that you said the ego is limiting what you can do with clearomizers, etc. In case you aren't aware of it, you can use anything designed for a 510 battery connection with an ego. The only limitation they have is the 3.4V output voltage.
Try a CE4+, or a 1.7 to 2.0ohm cartomizer or clearomizer made to fit a 510 battery. You'll see a big improvement over their "tank system".

Sailorman is right, you can get a basic passthrough (PT) setup for cheap, check here, USB Passthroughs. You'll need a 2 amp usb adapter to run a PT effectively. The cheap 510 PT's have a problem with weak cords so if you can, spend the extra $$$ on a better one.

Ah-Ha! a pass through! I should have figured they were already made,

That phrase and google got me to one that is variable voltage:
USB Variable Voltage Passthrough

Yes I am ditching the "C" part, I loaded the last two C atomizers from my kit tonight, I have some CE3 XL's coming in the mail, along with my favorite juice which I ran out of (typical noob mistake), both are delayed by memorial day,

some things I would like to play with that the eGo cannot do are low resistance atomizers, most sites say aything below 2.5 ohms can shorten the life of the eGo battery.

Wattage regulation is controlled by the resistance of your atomizer/cartomizer.

I was thinking more in the Darwin sense of wattage regulation where no matter the resistance of the atomizer swapped on the Darwin will adjust itself to deliver the same wattage as before, I know a bit about electronics, I am familiar with constant voltage regulators and constant current regulators but not constant wattage regulators.

If you have a 650mah ego, that may be true but, frankly, I wouldn't use anything above 2ohms on 3.4V battery. The loss of battery life is insignificant compared to the increase in performance.

With a 2.5ohm on a regulated ego, you're only getting 4.6 Watts. That's terrible. Horrible even!!
Most people like to vape between 6 and 10 watts. 4.6 is total failure.
With a 2ohm, at least you're approaching an acceptable 5.8 Watts.

That's the other problem I have with eGos. Besides their crappy tank/atty system, they're underpowered.
The best you can do with them is a 1.7ohm Smoketech "Ressurector" cartomizer. That'll get you 6.8 watts, which is not too bad. I've not heard of problems with an ego battery and low resistance since they first came out. They've changed the MOSFET since then and people use them with 1.7ohms all the time. It may decrease the battery life somewhat, but I don't think it's enough to negate the fact that it's the only way to get a decent vape off of them.

If you have a 900-1000mah ego, it's not even an issue.

At the circuit level, I'm clueless. Are you familiar with the "Kick"? It does that in any PV with an 18mm diameter lithium battery. You can put it in a mod with an 18*** battery and it'll automatically adjust the wattage to a value you set, regardless of the battery charge level or the resistance of the carto/atty you attach. So, your tube mod can become an instant Darwin.

Just got a new toy off Ebay, a lab grade DC power supply





1.0 - 16.5 VDC 0-4Amps, should be perfect for vaping,
