You have gotten way over my head when you are talking watts. I have been vaping for 3 weeks+ now and all I understand is the power chart, where you take the ohms of the coil and set the voltage about 2 above the ohms. Where does the "watts" come from and how do they affect the vapor?

Hey, R1Barlow.

You're at a good place and starting off well. As you continue vaping, you may find yourself with a variable wattage device (vw). You are using a variable voltage device (vv). To simplify greatly, voltage is a measurement of the electricity supplied and wattage is a measurement of the electricity consumed by the heating coil. Ohm's Law (Ohm's law - Wikipedia, the free encyclopedia) tells us that watts are determined by dividing the square of the voltage (Volts x Volts) by the resistance of the coil (Ohms). ie A 2 ohm coil supplied with 4 volts [(4x4)/2] is 8 watts. A vw device measures the resistance of the coil and supplies the correct voltage to achieve the desired wattage. This was more important prior to vv/vw devices and continues to be VERY important when using mechanical devices.

If you move past where you are now in vaping, you'll want to have a reasonable understanding of Ohm's law, if only for safety's sake.

Happy Vaping!

Everything is a Trade Off.

A 1W ~ 200W, Constant Voltage APV with an Adjustable 510 Pin that has 5,000mAh would work for 99.99% of the Vapers in the World.

But can you make it for 17 or 18 Bucks? And would it be the Size of the eLeaf iStick?

Price and Size appear to be the Primary Design Criteria's for the eLeaf iStick. And for what they Packed into the Size at the Cost that they are Wholesaled it for, I think they did a Very Good Job.
Economically speaking, I'd have to agree with you on all counts. The iStick even as it stands will most likely satisfy 9 out of 10 people that get one. At $35 it's really a no-brainer for those 9 folks.

But I have to say... if a simple software algorithm could have made the PWM output on par with the VV3, MVP... I don't understand why Eleaf didn't do that. Perhaps I'm naive about such things in the manufacturing process though.

Edit: Zoidman... you had one apart. What kind of chip is on the board if you noticed?

Too true. Everything is a trade off.

A 3 - 5.5 volt/ 4 amp device, with a 2200 mAh battery and adjustable 510 pin, capable of firing 1 - 3ohm loads; all for under $40 would be great for 75+% of the World's vapers... And Eleaf managed to mess it up, IMHO.

I'm not a Chip Tech. And I don't Know what the Chip inside an eLeaf iStck Can and Can Not Do.

But I do have a Background in Manufacturing. And if you are Selling something for say 20 Bucks wholesale, 4 or 5 Dollars may be your Entire Profit Margin.

So if it Isn't a Simple Task of Burning a Different Algorithm into the Chip you want to use, a $1 Upgrade to a "Better" Chip would put a Huge Dent into your Profits.

The Power/Logic Board and the USB Board didn't have any P/N's or OEM Marks that I could see. That was Another Reason I wanted to see what was Inside an iStick.

Well... Then I guess you Shouldn't Buy One.

Such decisions that compromise the final product are usually stupid mistakes or made by bean-counters. Look at the history of American manufacturing.

If a manufacturer can save $.25 each on a $10 product (0.025%), which is probably the cost of the iStick from the manufacturer to the distributor/wholesaler; and they produce 3 million units; Eleaf just kept $750,000 in their pockets...

I believe the iStick is using a proprietary chipset. But I may be wrong.

All I know is that for the Retail Price and Size of the iStick, eLeaf Wasn't going to Satisfy Everyone.

But from what I have seen in this Thread, eLeaf did a Good Job of giving the Majority of Users what they Wanted.

A Small VV/VW APV with Good Battery Life at a Dirt Cheap Price.

I got what I wanted and loved it enough to engrave on it with my dremel tool :D My iStick works Great. Here's what she looks like now

It's a great value to be sure. My KFL+ vapes wonderfully on this thing at 2.7ohms. It's got solid construction and of course ample venting with the micro USB port. The OLED readout gives everything you need at a glance and I can appreciate the elegant simplicity. I'm just hoping Busardo points out the incongruities on the low end and makes enough noise about it that Eleaf might listen. I'd gladly pay an extra $10/$15. (Either that or Innokin takes a cue).

I don't. My formula is keep the wattage low and the oHms high.

Is there a larger version of those photos?
Exactly what went through my mind just now.

We've not met before AG, hulloo and I gotta say wow!
The engraving at first blush looks great! I'd be willing to wager that's not your first shot at the art?

Hulloo back at cha :laugh: I like to create things and paint mostly, crafty kinda monkey I am :D I don't engrave often
