Can anyone tell me when the official release date for the Istick 50 watt?

Istick 50 watt?
- Thread starter Forrest Johnson
- Start date
I think eLeaf has a limited window to get these out, other manufacturers are starting to follow the line of small, powerful mods. Cloupor fucked up their 30 watt entry into the small and powerful mod market...
iStick 50 is now available on Longhorn Vapor.
Price is high at the moment, but hopefully it will be dropped down in the coming days.

Just got mine and here's what I'm experiencing. Maybe someone can tell me why. Starting in the low wattage range: 8.5W on my Sig Mini 30W hits way harder than 8.5W on my iStick 50W. I have to turn the iStick up to 15W to get the same hit as on my Sig at 8.5W.
WHY?
WHY?
PMW??

PWM - Pulse Width Modulation. I don't actually have the Sig but it's my understanding that PWM is selectable in the menu. If you want to buck the voltage down for lower settings it needs to use PWM to do it as it doesn't have a DC buck circuit. The DC setting bypasses the chip and gives you direct battery voltage. The Istick uses PWM as well for bucking but does so automatically and uses regulated DC for the settings where it can meet them without PWM. At 8.5W the Sig likely needs to be using PWM to achieve it. You can set it to 8.5W without it but that's not what you'll get. Looking at the Busardo review of the 50W the scope stuff shows it as accurate.

I only remember choosing the five memory settings: M1, M2, etc. I thought about Pulse Width. Can it regulate itself into PWM under certain circumstances?
Does the Sig also auto-regulate itself with pulse width modulation? And when you mention the Busardo review on the iStick 50W, are you saying that it is accurate in that it is tuned to mean rather than RMS?

Based on the promotional material - "One unique feature of the Sigelei Mini 30W it’s that you can switch it from regulated power mode(PWM) to a mechanical mod mode(DC-DC). Mechanical mode bypasses the chip-set and allows to sub-ohm lower than the chip allows." - you pretty much have to have it in PWM mode for any regulation at all. My 50w seems pretty accurate compared to other VW devices I have and Pbusardo's scope readings agree. I just wondered how you had the Sig set. Depending on the resistance direct DC could give you considerably more than 8.5W. I don't know whether you could choose DC and still adjust the wattage on the display but that would account for a difference. I haven't seen any scope results on the Sig chip so I don't know about the accuracy of the chip when it's regulating.

It's tuned to RMS rather than the mean used in the 20W and only uses that to buck down. It uses a DC boost circuit to boost up and switches between the two automatically as needed. It puts out the correct voltages by scope readings to achieve the chosen wattage using Ohm's law.
The Sig has PWM to regulate but I don't know what method it uses or if it's accurate. Not saying it isn't, just that IDK.

When you refer to your 50W are you talking about a Sig or the iStick 50?

The Istick 50W. The Sig it appears can boost up using either PWM or DC but needs PWM to buck below battery voltage. I understand you can select the mode by holding the down and power buttons at the same time. Perhaps you have been using it in the DC mode which would account for the difference at lower wattage's.
Well, like I said, I don't remember specifically setting it to PWM, but since I can control the vw I assume it's in that mode, at least, according to what the instructions are telling me. You have a terrific grasp on electronics, Lefty. I'm winging my way through this with what little intelligence I have. Gotta love my unregulated!

Maybe it's power and down to go back IDK. I just Googled it and picked it up from another forum. You know you can't trust stuff from forums.
I wonder does the quick memory remember the PWM and DC settings as well? Just for giggles I'd set it to PWM and manually set it at 8.5W and see if it still hits as hard.

I hear that they eliminated the PWM on the ipv mini 2 because people just don't use it. I'm starting to see why. I just compared the two again: Sig in PWM at 8.5W and iStick 50 at 8.5 W. They're pretty close, with the Sig slightly more powerful. Hardly noticeable.
Oh snap, I RMA my sig 30to 101vape... Why
The mod wont turn on then it kept showing the message PMW!! I didn't know what to do, neither 101vape,they said it was a power management problem, lol..and it was auto firing on me... Oh well waiting for replacement..

Anywhere it's above zero and not snowing is good. PWM is for when you can't turn the DC down enough to suit whatever atty and coil you're using. Most regulated mods until the DNA chips came out used PWM to regulate power. It's a cheaper way to do it. It just turns the power on and off quickly. The longer it's off the lower the power. With DC you'd need one circuit to reduce and one circuit to boost. Doesn't seem that tough to do but most DC chips only do one.

All I can say is I'm pretty impressed with my iStick. The battery life on mine is amazing. I have been vaping on it exclusively for the past 24 hours with my Magma rda dual coils 28ga .8 ohms at 20 watts and the battery charge status has barely moved. It's moved so little that you have to really look at it to even notice that it's moved at all!! And the vapor is excellent. Huge clouds and the Magma gives it great flavor. It's solid, fits perfectly in my hand and no button rattle. It's the perfect size and is just made really well.
I like it so much I bought another one yesterday (got SS this time). Got it for $49.50 and free shipping with a coupon code at Elevated Vaping http://www.elevatedvaping.com. To get the coupon code just go to their site and then hover your mouse over the back button and it'll popup and give you the code.

Just had a look and they are overpriced on just about everything.

I didn't use mine exclusively but it went nearly six days before I gave up and threw it on the charger with a couple of bars still showing. Mostly around 14-15W but some over 20 and a short while at .4 and 50W. Time between charges and the ability to down regulate when needed was what I was looking for and it does that very well.

6 days..wow that's amazing! From what I'm seeing with mine I guess it'll be close to that before I need to charge it. They apparently have very efficient circuits/electronics to be able to get this amount of life out of 2 18650 batteries.
