E-Turbo ..my new invention....

I think you mean 1200 mA? mAh is used to tell the capacity of a battery. mA is when you measure how much current is being used by the atomizer. Which is usually around 1A (1000 mA).

Depends on the voltage. Eg. I see a lot of USB adaptors used here. Unless they have stepdown transformers (I very much doubt this), these run at 5v. Since the resistance of a working atomizer is reported to be around the 3.5ohm mark, with a stock battery (nominally 3.7v) we should get around 1A, (assuming the battery doesn't burn out ) but with USB, it would be more like 750mA. You would get 1200 mA with a 3v power source.

[Bertrand]

Forgot to mention. USB specification says power is 500mA, so I guess that would be the limit (and it may do bad things to your computer) unless you have something like this:

DealExtreme: $5.97 Slim USB Power Adapter (1000mA)

Hey thanks for explaining. Would it also be an idea (like mentioned earlier) to use AC current instead of DC or wouldn't that make any difference?

AC Current?...that will take up space in an already congested space..I suppose so.. but, needs to be a portable device as well...hmmm...good suggestion...will think about it...Thanks yo han...

Well doc, I have at least 10 dead atomisers saved up ready to be revived Will it get rid of burning taste like when an evil battery does its cleaning cycle?

No Bad burning taste after using it and totally eliminates the need for the cyclical cleaning that many of us has experienced...I called it the "purge"..yucky as well...I hope your atomiser are just in tired dormant stages..not entirely dead atomisers...still on field testing..getting as many dead atomiser and see how many will be recovered...will let everyone knows the tally later on...

great idea!!! congrat!!! sorry -you have almost tell

Think I let half of the cat out of the bag..

I have used rechargeable battery ..the 1200mah was meant for battery capacity...the output was somewhat lower after all the "appendages" attached sapped away some of the power..yes, I will need to remeasure all this later on...thanks again yo han..you been very helpful....

Been following this thread avidly - great stuff! Certainly sounds like a product that will be very popular amongst e-smokers. I'm even beginning to think perhaps the e-cigarette suppliers will think its a good thing - at least it will save them constantly sending out free replacement atomisers/batteries...

Good work Doc and when you get a chance to focus your attentions on the pipe or cigar, you will have a mucho happy customer! In the mean time:
GOOD LUCK!!!!

Thanks SD..I hope so...it will change the landscape for e-smokers again....that was the actual aim..to be cost effective for both sides..the manufacturers and the consumers as well....

On E-pipe and E-cigar...ahhh....still not able to come out with a suitable alternative yet..give me some time..I will do something for those types..(only thing is I don't have any e-cigar at the moment)....

Betrand,

As far as we can tell the operating current of an atomiser is approximately 80mA. Even taking the small batteries used and the usual maximum 4 x capacity rule you could not reach the 1A (1000ma) that you suggest. If you follow some of bastages threads you will see that he has succesfully run atomisers on USB on laptops (usual max current 100mA) so 80mA for a 901 atomiser seems about right.

Some of you people really do need to take a quick look at Ohms law - there are some wildly incorrect figures being bandied around here, most sounding very much like the voice of authority when, in fact a lot of it is just plain BS.

- "If you don't know the answer keep your traq shut!" was what my old Mentor used to tell me, and very good advice it was too.

My standard classic batteries (li-ion) are around 4.1 volts when fully charged, the atomisers have a resistance of around 4 ohms, Ohms law states that the current drawn by the atomiser will be around 1 amp.

There will amost certainly be some circuitry in the standard battery electronics that reduces the current slightly, maybe 10-20%, say - 800mA.

Those of us that are running our e-cigs directly from an external battery pack, and with only the manual switch in the circuit will be pulling around 1 amp using 3 AA or AAA ni-mh batteries, and they all seem to be doing very well on it, thank you.

I'm thinking of running mine on 4 AA or AAA batteries and including a small regulator circuit to limit the current to around 1100 mA.

No worries Doc - I guess the e-pipe & e-cigar would be really good ones to nail due to the fact the atomisers aren't really disposable.. I mean most people don't think twice about replacing a 901 atomiser when it dies, but to replace a whole pipe every two weeks...

I can just picture it: And now after much waiting and anticipation, we can exclusively reveal... bom, bom, bom.... the new e-turbo pipe enhancer... applaud

Good luck and we're all cheering you on!!

..It's okay BarryK...lots of wild guessing....not all of us understood fully the "electrical engineering" knowledges....I am still struggling to understand something that not even my field of work...good to know though that we are all learning and hopefully guided by the right way...

Thanks GS..I hope I can do that as well......

Small update..
Ran into some trouble today..Hit 1800maH batteries and nearly fried my atomiser(as well as my fingers),it get super hot but surprisingly the atomiser now still functioning..hmmm....something there need looking into for...the wires all melted down to the cores and I can hear "pop"ing noise from the atomiser as if there is fireworks going on inside then all hell break loose.....like looking into a Lava filled Cauldron....but then the atomisers did not fail!....still working diligently as ever...I need some help here...technically it should be fried but it wasn't...I made those batteries from a old cellphone ...it measure 4.19v 1800mah....any ideas people?....can use a hand here...

:)..It's okay BarryK...lots of wild guessing....not all of us understood fully the "electrical engineering" knowledges....

Bit OT sorrry. I think I started this by explaining you could actually get 1200mA (rate of electron flow) through the atomizer by reducing the voltage (average energy of the electrons).

Ohms law is very simple. R = I.V (R is resistance in ohms, V is potential in volts, I is current in amps.)

But, it does assume you've got sufficient power from the source, hence my comment about USB specs being 500mA / 5v. (If there are no power restrictors on your computer's usb power supply, you could very well melt something on the circuit board of your motherboard; if there are, then ohms law isn't going to work.)

Similarly for batteries: the little batteries in the small ecigs are meant to be about 150mAh. I think this gets tested over something like 20 hours. This means that the voltage doesn't drop by more than 'an acceptable' amount over 20 hours drawing a current of 150/20 = 7.5mA. Since the current is more like 1000mA, in an ideal battery you 'should' get about 10 minutes (150/1000 hours) of atomizer use. This is not the case, since the batteries are not ideal, and lose their charge more quickly when providing a higher current. It also kills the batteries, as we all know. ;)

Peace. hehe

Thanks Bertrand for your valuable input...much knowledge added as this thread grows....

Anyway, just for all to know, I am rolling out 20 units of pre production models for my locals here by next week( who had all agreed to keeping this under wraps and not for resale clause..they will have to sign a binding agreement pertaining to copyrights before buying these pre production version...all duly done up by my lawyers and if any infringement /breach of the agreement will be met with a severe consequences... )...sounds serious..huh...

There is a significant change to the model looks and design after much consideration and the battery power is now set at 3.6V/1800mAh with a 5V/400mAh DC input....and a universal USB port for charging purposes( I will post pics later..sorry still no video yet)..much slimmer and "pocketable"...Adaptors design has been improved and better hold/grip achieved for ease of use....

The battery roughly lasted 2 days on intense use(that is vaporising 2 ml to 3ml of liquids per day.. that is being used every 20 to 30 minutes for 2 minutes of continuous "smoking"...ahem,.. I employed a heavy smoker for that measurement) and 3 days plus for minimal use..around 1 ml of liquid vaporisation...yep, it's the Gas guzzler alright for the e-cig world if used intensely...

Interestingly, light smokers does not like it as the power is overwhelming...describing it as choking sensation....so might need to make a "lighter version" but heavy smokers will appreciates its power.. Nicotine /throat hit is very consistent to the last drop...

I have been using it for more than a week now and I found that it helps me to actually reduce my e-cig usage as well...I don't have to vape all the time like before with the OE batteries...I put that down to correct delivery of nicotine into my system so it actually stop me from puffing further...well, that means good news for those who will need to cut down later on e-cigs too....more to discover I guess...

That's all at the moment...I will update again as soon as more data /feedback from my users..hope you all can bear with me till full release later on...

Cheers....

Good news. One small thing: Do an electromagnetic radiation test on the unit. If it's to be stored in a shirt pocket, it will be in extremely close proximity to the heart. Make sure the EMR is not at a level to disrupt the heart rhythm of even the most vulnerable person -- or even someone with an implant. In fact, shielding would seem safe and shouldn't be prohibitively expensive.

Good luck with further progress and glad to hear field testing is about to begin.
