If you've been reading my blog you'll know that I got into vaping in April, and bought a load of EGO's
I tried LR carto's and was impressed with those then LR 510-T atties which I liked too
Next on the scene were dual coil carto's that gave more vapour, with 2x 3 ohm coils they were effectivley 1.5ohm resistance, there was lots of speculation that these would cause my EGO batteries to fail but this turned out not to be the case.
The next thing I tried was 1.5ohm atomisers from Cisco and the HH.357 atomiser.
Just 1 coil on these, so burning much hotter these gave a wicked vape but needed constant feeding with juice, it's very easy to get a dry hit off these and the coil wire can melt so not that reliable.
From there I got my first boxmod using an 18650 battery. It's a bottom juice feeder and paired with an HH.357 attie, dry hits were now much fewer and further between and I could refill the attie while driving by just squeezing the bottle.
The 18650 proved to be the only problem with this setup because unlike my 3.4v regulated EGO batteries this battery would supply 4.2v fresh off the charger. This would make a .357 attie spit and burn the juice when the battery was fresh right down to a bit of a lame vape at the end of the charge.
That's the problem. You can only give an atomiser coil so much power before it overheats, burns the juice before burning out itself.
Then at Vapefest last weekend I think it was Psycho (I forget, so many people were kind enough to let me have a go of their expensive mods) anyway I had a go of a Darwin.
I put a dual coil atomiser (from UK Eliquid) on there and started upping the power in stages to see what happened.
The 2 coils of the atomiser were able to handle a serious amount of power without burning the juice but as the power went over 10 watts they were getting hot enough to produce as much vapour as a 1.5 ohm atomiser....... but doubled!
Stonking performance, the biggest lungful of vapour I've had.
So with 11.7 watts of power on a 1.5 ohm dual coil atomiser the Darwin was pumping out 4.2v
This was the setup I wanted but a fully charged 18650 is only going to give you this much power for about 30 seconds off the charger (actually under load the voltage would probably drop straight away)
The Darwin is both very expensive and won't take a Mega Dual Coil carto without unscrewing it every time, plus tube mods like the silver bullet or the Provari look much nicer. and have swappable batteries.
The silver bullet is just 3.7 or 7 volts so that's missing the sweet spot by a long way on the current release of dual coil atties and carto's so it would have to be a Provari.
The Provari can't do the business either though, as we established from using the Darwin, the sweet spot on the dual coil is 4.2volts all good so far but because of the dual coils using twice as much power the load on the Provari would be 2.8 amps at this voltage, and the Provari has a cutoff at 2.5amps. Firing the device at any more than 3.9volts just results in an overload error code and the attie won't fire. This was a restriction set before the emergence of dual coil atomisers and Provape are going to need to get this sorted if they're going to keep selling devices.
So I bought a Trio Boxmod, a device that uses 2x 14500 batteries and gives 3 regulated output voltages 3.7v 4.2v and 5v. Perfect
And it was, the mod just hit the sweet spot on a Mega DCC and it could handle the power. Until I broke it.
And for me that's the problem. The Provari the Darwin and the Trio all have a lot of shortcomings because of the expensive circuitry, delicate components, amperage limit, or fixed or stacked batteries
Now I'm no genius, but let me run this theory by you and I'd welcome your comments.
All you need is a basic tube mod with 1x high drain 18650 battery and a switch that can handle a good load like the silver bullet or maybe even the 510n or E-Power tube mod.
So lets say a cheap tube mod like that £30 tops
And some Mega DCC's at £3.00 each. Not the regular ones like we get now with 2x 3ohm coils in them but with 2.5 ohm or 2.0ohm coils instead
Here are the numbers;
2x 2.5ohm coils
1.25ohm resistance at 3.7v
2.96 amps
10.95 watts
or 2x 2.0ohm coils
1ohm resistance at 3.7v
3.7 amps
13.7 watts
All 18650's are capable of handling at least a 4amp continuous load, the AW's can handle 5 or 6 amps. You couldn't run these babies on an EGO but there would be no problem using these on a cheap tube mod with 1 cheap replaceable battery. Or a nice bottom feeder boxmod with 1 battery and 1x 6ml juice bottle that you could easily hold in your hand.
What do you guys think?
