Hey @davetherayon
That's a brilliant idea!
I did add a 0.22 ohm resistor in series which I can switch in and out. This just gives two power levels, I needed the slightly lower one to keep flavours like Kent from burning all the time.
Of course it doesn't give the smooth control that your rheostat would.
Cheers - Jono

Late response from me - sorry!
It's a Sony PSP 5v 2A mains adaptor, which provides good, safe isolation from the mains and 10W continuous power.
The desktop part is made from various scrap plumbing parts with a standard ecig thread adaptor in the middle.
I extracted the ecig part from the top of an old Chinese battery.
On the side I fastened a 2A microswitch, positioned for comfortable operation.
There's an LED and 200 ohm resistor in the circuit too, wired across the switch contacts so that it lights up when the Kayfun is screwed on. The LED goes off whilst the switch is activated. It's not essential but it's useful and of course it looks nice.
I use a Kayfun 3.1 and a Kayfun Lite clone on top, similar diameter with steel finish to match the other parts.
The desk vaper is made from the parts I happened to have to hand, so endless interpretations of the basic design are possible.
Cheers - JonoClouds
EDIT
Forgot to mention coil should be 2.5 ohms!

Yep, it's what VapingBad said, really.
Pass-throughs are either limited to the USB power limit, which can be very low (even a 1.5A 5v USB charger would max out at 7.5W, the cheaper chargers are around 1/3 of this), or they are simply charging your battery all the time and you are drawing on battery power each time you fire up. The mains vaper thingy always has 10W on tap, no battery or USB required. Oh, and it was free, which is important for me as I have very limited income :-(

Well, I've been using the mains vaper for a month now. I've re-coiled the Kayfun Lite a couple of times, once because it wasn't wicking fast enough to keep up.
It's working well, with very consistent performance. The vapour is quite hot so I've been trying a few different drip tips (delrin, alu and steel) of various lengths.
I use the desk vaper all day. When I'm out and about I take a smaller clearo on a Spinner.

 I'm usually at my desk for much of the day. After months going round the constant cycle of charging batteries, I decided to eliminate them.
This is my second desk-vaper. Both of them work from the mains and I use them at 10 watts.
Hang on, I hear you say, you're going to electrocute yourself with one of those things. Well, I use 5V 2A switched-mode power supplies, like the sort supplied with Sony games consoles. These provide complete isolation from mains voltages, a claim which I have been careful to verify myself by testing each one.
The one in the pic is made from plumbing spares, a microswitch, a bi-colour LED and a resistor. There is a 510 connector at the top, constructed from the insides of an old cheap clearo. The threaded centre column in these clearos is the same as 510 threads. On top is my Kayfun Lite clone. There's a very small overhang with this RBA as it it maybe one mm wider than the mount. I coil it at 2.5 ohms to get 10W at 5V, this works very well. It's half a dozen turns of kanthal ribbon on a conventional doubled-up 2mm silica wick.
So the result is a safe, reasonably powerful, battery-free system. The only thing I had to buy was the Kayfun clone!Footnote to cover my butt: Mains voltages are dangerous. Please don't try to construct a mains-powered device unless you have the skills and knowledge to keep you safe from shocks, fire and any other hazards. |

doveman, the 1.8ohm would be my choice on a Spinner as it's good but it's still a bit of an Ego battery on steroids. 1.6ohm would work but you'd have shorter battery life.

If you think menthol is persistent, try LT Rose. It's a lovely fragrant flavour, really enjoyable and one of my faves. Trying to eliminate it from your equipment afterwards is quite another matter!

Very interesting thread.
It's true that almost every study has been examining nicotine from smoking, not vaping. Having said that, it is well established that nicotine is a vasoconstrictor. It causes the small blood vessels at your extremities to reduce the amount of blood flow, causing effects like cold fingers and toes. (It also raises BP.) This could be significant for diabetes sufferers because diabetes can also feature reduced peripheral blood flow. In severe cases, diabetics have the miserable experience of damage to body parts resulting in amputation. www.diabetes.co.uk goes as far as to claim that 50% of all amputations are in diabetic patients. The feet, particularly toes, are frequently affected.
So IMO combining diabetes with nicotine is probably not advisable for this reason. Of course diabetes + smoking is likely to be much more dangerous that diabetes + vaping.
Another poster rightly mentioned that vaping is probably more harmful than nothing at all and this is entirely reasonable. It does break down for people who use nicotine to ease the (very distressing) symptoms of mental illness (e.g. clinical depression and anxiety). For them, vaping is a much safer alternative to smoking and still gives a great deal of comfort and relief. The benefit of this should not be underestimated.
Best wishes
Jono

jonoclouds - so I presume I'm right in assuming from the OP's remarks and yours that a new charger might be the solution, rather than a new battery - sounds good to me 
It is always worth having a good charger anyway, whatever the outcome is!
Spinners are good batteries, I love mine. The 1300mAh ones last for many happy hours of vaping.
All the best - Jono

My 1300mAh Spinner takes several hours to charge from flat using a 500mA wall charger. This seems about right, too - theoretically it should be just under 3 hours but of course batteries are never as perfect as theory, there are losses and ageing to account for. Also, a good charge-control circuit (like that inside the Spinner) charges on constant-current to start with, then constant-voltage towards the end. The result is extended charging time but much improved battery life in terms of number of charge cycles.
Very long charge times (like the 7 hours that the OP mentioned) could simply be due to poor chargers - some of those imported from China are embarrassingly simple inside and are not capable of charging at the rate that they claim on their label.
DiscoDes posted earlier with doubts about the hypothesis that setting the dial to 4.2V speeds up charging. His doubts are well-founded, as the setting only affects the discharge rate, not the charge rate. The dial tells the buck/boost circuit what output voltage to maintain, that's all.
In my experience, Spinners are excellent devices and I would definitely recommend them.

Sounds 100% normal. I use iClear16s and vape much like cigar-smoking, into my mouth and out through my nose.
The first few draws after a break always produce an impressive tingling in the nasal cavity, this soon disappears when chain-vaping. After another break of 30mins to an hour, the next few draws tingle again. I noticed this effect from early on in my vaping career (over a year ago) and it is still exactly the same. I put it down to mucus lining (nasal) sensitivity to nicotine which fades as the receptors become saturated. Stronger nic eliquid does not seem to help me much. Instead, I mix my juices quite strong so that I get pleasure first from the nic hit and then from the juice flavour.

I favour the leafy flavour of LT Ecig's "Inawera Blend", not like ashtray at all!

This is a difficult one. UKIP are pro-ecig and anti-windturbine, so those policies gain my favour. Sadly, their (only thinly-disguised) xenophobia and their misguided employment policies count against them. Tory and LibDem performance over the last few years is laughable. Labour are just too far behind the curve. What to do? Probably UKIP because vaping is such an important part of my lifestyle now, but it's a grudging vote for them all the same.

Great thread - thanks Clivia and also Karma for labelling it. (People lookup isn't working just now for some reason.)
I was a light smoker for about 20 years before I started vaping. Now I smoke no more than once a month. That's as good as giving up smoking as far as I am concerned!

Thank you vigowomble for your link to this excellent article.
It is well-established that people with mental illness use nicotine to self-medicate.
Smoking and vaping help relieve the distressing sensations of depression, anxiety and other similar mental states.
I know this from personal experience, and I am well-informed through my association with mental health charities and a well-respected mental health research organisation (which I cannot name here).
Vaping is a marvellous alternative to smoking which still provides its benefits but without its dangers. Now that e-cig technology is maturing, there is no need for mental health sufferers to trade off the risks between an early smoking-induced death and the alternative probability of an early death "by their own hands." Yes, it really is that serious.
All the best - Jono
