Good thinking!Maybe if it's posted on youtube those suppliers will start sending their cartos here. We'll make sure Katya's topless avatar starts it off.

Marking you off of my "free carto" list....
Well you're welcome to make suggestions on the "changing of the avatar". Should it stay or should it go?
After all you guys are the experts I'm only a neophyte here.
Ok, I'm not an expert by any means....
Basically the PTs (power supplies) being sold with the kits are ... well ... junk.
First of all there is the issue with being able to supply sufficient current. Let's take a standard Joye 510 ecig (w/battery). Joye 510 atomizers run about 2.2 ohms to 2.4 ohms. Joye 510 battery delivers something like 3.2 volts? Plug those figures into
Ohm's Law Calculator
and you get something like 1.5 amps current.
Ohms law relates volts, resistance, and current. Fix one of those 3 variables and the other two are directly porportional to each other. In our case the resistance is due to the physical attributes of the atomizer/cartomizer and for all practical purposes, fixed. In the example above the Joye 510 presents 2.2 ohms resistance. The power supply is going to have volts (potential) and produce some amount of current flow through that fixed resistance. Let's say the power supply has infinite capacity and you set the voltage on it to 3.2 volts. You would get about 1.5 amps of current running through the atomizer coil.
Now let's say you set the voltage on the power supply to 5 volts. With the 2.2 ohm resistance you would now get about 2.3 amps of current running through the atomizer coil.
So back to the regular Joye 510 kit, we're trying to draw 1.5 amps of current right? Let's look at the USB port on our PC for a power supply. The ratings on a (typical) USB port on a PC are 5 volts and can supply up to 0.5 amps... Well, we're trying to draw 3 times that amount of current. The resistance is fixed, the USB port can only supply 0.5 amps of current so that means that voltage has to give. You're not going to get 5 volts. Using the calculator and plugging in 2.2 for ohms and 0.5 for amps you're going to end up with 1.1 volts. Pretty weak right? That's why the PTs (without battery) are pretty much worthless when plugged into a PC.
Ok, the USB port will produce power (as wimpy as it may be) constantly. We don't hold the button on the PV down constantly. If we put a battery in line then we could store up while not vaping and release it (faster) when the button is pressed. Works pretty good since you're not vaping a lot more of the time than you are vaping. The problem is that it's a teeny tiny battery. It's not so much that it doesn't hold much it's just that teeny tiny batteries get really stressed when releasing relatively large amounts of energy in a short amount of time. So while you can get better performance while it works you're stressing the battery and it's lifetime as a battery is pretty short. A larger battery like a 14500 would last much longer but who wants that hanging from their cord. and they cost more.
In any event, the 5v PTs you usually get to plug into the wall are poorly made and woefully under rated/built for our application. Don't know the particulars but there are usually windings and/or some eletrical componentry in there that's all encased in resin (or not) and it gets stressed and it quits working. Lots of it is of the very cheapest Chinese manufacture overseen by the same fine quality control that our atomizers and cartomizers are manufactured under. I'll qualify my opening statement. It's designed/rated for requirements less than what we need AND it's junk. You're overdriving something that's woefully underpowered to begin with.
4 or 5 PTs... With that amount of use it sounds like it would be cost effective for you to invest in a quality power supply/PT. Something like this:
Enercell High-Power AC Adapter : AC Adapters | RadioShack.com
would be sufficient. Pick your voltage and it can supply up to 2 amps. Not quite enough but sufficient. And I would expect it to last years if you don't crimp the cord.
(you would need to get the correct plug for it to fit the device/PT you're using. A fixed voltage (3v or 5v) might be cheaper or more durable if not cheaper but you lose the flexibility to choose your voltage.
I'm not familiar with the 2 amp power supplies that someone (one of our suppliers?) has conscripted from China. The fact that it's rated for 2 amps says something for it. He was selling them for $5 or something before he starts supplying them to WallMart where he expects them to be priced at about $15.
No details but maybe that helps.
The good suppliers actually do that. I will, hopefully, be getting some of those XL Truemans sometime next week from Ross at Vapors Etc. He ordered samples and would like us to take them for a spin before he decides to stock them. So, stay tuned. I'll share with those of you here who are interested in testing them. I'm not sure how many I'll have, maybe six or so, I'll let you know.
Nice avatar. Legs will only take you so far.
Neo and Tibur and Salt! Good Prophets finally carries the 3.0Ω blank 4081s. Time to order.
"Neo and Tibur and Salt! Good Prophets finally carries the 3.0Ω blank 4081s. Time to order."
lol, katya, still got too many left from the trueman order. i've been vaping with the 808 e2 for the last 10 days![]()
Aw, man. I'm trying to make mine last. I only bring one out a week. Disciplined, aren't I?![]()
I was just debating between the two. Provapes is also rated at 1.8-2.0.Just to report on the cloudsofvapor 1.8-2.0 LR cartos for the 510. I swore I wouldn't get any more but then did when I picked up some E2's from Bruce but just had another go out and this time on an eGo. I normally use the Provapes LR for the eGo and was using the 1.8-2.0Ω ones on the Bart and Protege but I still haven't got one to last over a week. I know some think that's about right but not me. Esp. after only losing one Provapes for months now. Again, these cov LR cartos are good - great vapor and still hold flavor well but imo, simply not worth it. Bruce says they're made esp. for cov (and I haven't seen that exact ohm rating elsewhere - and yes, they meter out at that) but he should perhaps have them make them more substantial than they are.
Anyone else have better luck with them than I have?
I don't know how you do it Neo. If I go 2 days out of a carto I feel accomplished.
Just ordered some of that.I'm going to have to pick some of the 1.8-2.0 ones up myself, just in case they are as stable as the older ones.
Just ordered some of that.
You will get my full report.nic,
If you get yours before I get around to ordering some, let me know how they are, meter, if you do that, etc.
New problem with Mega Ego cartos - On my last 3 the metal cap covering the carto (that connects to the battery) has completely fallen off on fairly new cartos. Has this happened to anyone else? I don't know if I can get the cap back on to work. 3 in a row not good.
