Alright.... the e-power mod

[AttyPops]

Cool. Thanks Java. Now if I knew what the NoeGo was .......

Sounding more like PWM regulated to 3.x volts. IDK how e.d.jobs keeps getting battery voltage tho.......

Sorry here is a link to it. Jazz cartopipe the first Cartomizer Pipe

 

[AttyPops]

lol.

So is it regulated? If so, to what voltage? Of course I don't expect 3.7 volts............but 3.5 ish?
Also, it could just be a power mosfet and follow battery voltage...........

The Epower is the same thing as the NoeGo i believe. Made by the same Chinese company. I got the 14500 /14650 model sitting here i just don't have any 14500 batteries. They also make a 18650 model that one i have tested out seems to hit the same as my eGo. Which for me is lacking i don't really enjoy vaping without at least 4.4 volts these days. Just thought i would throw that info out there.

I think you are exactly correct, the E-power is just a rebranded NoEgo (or vice versa). I don' have either so I can't say for sure, of course, but that would be my guess from everything I've seen.

Who is testing it and getting a regulated output? I'd love to see a video/picture series of someone testing the battery for voltage then testing the same battery in an e-power and showing the e-power outputting a lower voltage. Then again, I haven't been able to test under load (should be changing soon) so if there's some sort of 'regulation' that kicks in once a load is applied ( one of our amazing electrical engineering types will chime in, i'm sure... and I love it when they do haha ) then that would explain it.. the switch is just so small.. like I said one of our resident experts would have to chime in about the complex electronics inside of the switch and what they could possible be capable of, it's beyond my understanding.

This http://www.e-cigarette-forum.com/forum/gotvapes/211178-epower-voltage.html seems to indicate just that.... but IDK for sure.

Like I said earlier.... I wonder if there are multiple types of switches........

I'm not slamming your results (in fact, thanks for testing) it's just that I hear both things........

A company in China makes them for sure SLB , Bauway , or so on. Really doubt it is joyetech though.

There is some sorta circuitry going on inside. When screwing the battery in the LED flashes. If it was just a switch that for sure wouldn't happen. Doesn't mean it is regulated but my guess is that it has the same circuitry as a Riva Ego , hello 016 and so on. I might whip something up later so i can do a loaded voltage and amp tests. Kinda busy right now i have a 100 Uv leds to solder into a board for my solder masking setup. Maybe i will get a video up later will see how it goes.

 

[MasterofChaos]

All I can say is if the switch is tiny, then it definitely doesn't have a switching power supply in it. If it had a linear power supply, then it would get hot under load. So its almost certain it has a MOSFET or other type of solid-state switch, which is just varying the duty cycle, if it is doing any regulation at all.

Really, the only proper way to see what it's doing is with an oscilloscope, that way you will be able to observe the switching and what the DC voltage it's switching is. That way you will see the maximum voltage drop as the battery becomes discharged.

 

[AttyPops]

Mosfet's don't have an inherent duty cycle.... they are just switching transistors. Fet or no, it would follow battery voltage, but with a processor it could PWM.... like the eGo.

Linear and switching regulators are different still. I doubt it's either of those.

I think you're correct Java... it's similar to an eGo/Riva. So it would be PWM modulated (and I would consider that regulated-ish). But it wouldn't follow battery voltage under load then.

I agree with the scope comment MOC, however I have neither the e-power (yet) or a scope. The PC scopes are very low res without an add-in board, so I don't bother.

Oh, and no hurry Java.

Another side note:
Kewl. Let us know how that works when ya get a chance.

Will do but now we have a thunder storm i might just shut everything down for awhile will all the lighting strikes. Bbl

Anybody asking about e-power / NoEgo check out the Vapeatron forums. Romaniac has a long thread where he discusses things about it. He contacted Smoketech about making it. They were in dev with the 14xxx model as he was contacting them i believe. Since he is just one person and not a vendor, he didn't have the buying power to make it worth while for smoketech to only produce them for him. He has no issue with them rebranding a different version of it. Although the 18650 version was his brain child i believe?

 

[MasterofChaos]

Atty,

What I meant is if it is using a MOSFET (or some other device) as a switch, then the only way it could be regulating the output is by varying the duty cycle. The "on" state would follow the battery voltage, as you said.

 

[mj64]

I've only heard of this product and haven't studied its claims in detail. What I **think** they are doing is trying to fulfill a market 'want' of a small relatively cig-like device AND variable voltage by throwing some really cheap adjustment at the **relative** voltage level. In other words they (the awful anonymous they) are trying to make mo'money and will spoil the VV impression for a lot of people that have never had a true quality VV device in the process.

 

[MasterofChaos]

mjmetz,

You are right on. That is what irks me, "they" are passing off subpar gear by hijacking the reputation of "high quality" VV gear, which was earned through consistent testing and proving over time.

 

[unloaded]

I've never seen any VV claims for the Epower. I have seen claims that its regulated.

 

[mj64]

Perhaps I was thinking it was a different one, guess this isn't the 3-click power mode one. But if it is regulated its should have regulated voltage, which it does not seem to. Otherwise what might regulated mean?

Oh yeah man didn't think you were, haha I'm actually just really curious. Looks like that guy's switch in that thread is definitely using some kind of 'regulation' (guessing PWM). I'm thankful my e-powers are not like that.. If you look in that same thread, there's another person with an e-power who claims his tested at 4.1 (http://www.e-cigarette-forum.com/forum/gotvapes/211178-epower-voltage.html#post3796746) .. looks like the logical conclusion is there's multiple switch versions. I just wish they would've mentioned it them.. version 1 and version 2 at LEAST... I bought the e-power for a true 3.7v device (Wanted 4.2 no load off the charger).. I would've been ...... if i got one of the switches with PWM haha.

 

[otrem]

What i got follows battery voltage. and have some kind of short ckt protection.

 

[AttyPops]

LOL. One thought I had is that different people's meters may tell us different things due to the PWM.

If it's reading the battery voltage during the "on" part of the cycle, then it would seem to follow battery voltage. If it's averaging out the PWM cycle to a net voltage, then it would read as regulated. No? So you'd have to know how your meter handles PWM at whatever frequency they are using.

lol.

It's not a vv device.
