Doing some testing today.............

Morning guys,

I was playing around this morning building some coils and wanted to do a comparison between single and dual coils and see if there is any benefit to dual. This is what I found:

MM USED	TVS DIABLO CLONE, BRASS W/ PATRIOT rda	TVS DIABLO CLONE, BRASS W/ PATRIOT RDA
COIL TYPE	TWISTED DUAL MICRO COIL	TWISTED SINGLE MICRO COIL
WIRE GAUGE	28 KANTHAL	28 KANTHAL
DIAMETER	5/64 DRILL BIT	5/64 DRILL BIT
WRAPS	10	6
WICK	ORGANIC COTTON BALLS	ORGANIC COTTON BALLS
OVERALL OHMS	0.5	0.5
LAG TIME	6**	9**
BATTERY	FRESHLY CHARGED 4.2 EFEST IMR 18650 1600mAH 30A	FRESHLY CHARGED 4.2 EFEST IMR 18650 1600mAH 30A
AMPS	8.4	8.4
WATTS	35.28	35.28
VAPOR	10**	8**
FLAVOR	10**	10**
** SCALE OF 1 TO 10

Basically, I found that the single had a little less vapor, and hardly any lag time. The dual coil setup had a bit more vapor but a significant lag time, about 3 seconds or so. I'll probably use the dual setup at home when relaxing, and the single in the car or at work. Do these seem pretty consistent with your builds?

Thx!!

That seems about right. I'd love to see some pics. I've yet to try twisted coils though...

 

[ConradM]

Pics of each? Was your dual coil 10 wraps total or 10 wraps each coil?

I'm using a dual micro atm and it's rocking my face off.



28g, 8 wraps each on a needle. .5 ohms. Using 18mg nic and it's just burning through juice and giving me a really intense nic hit.

Nice coil setup. I've tried RBAs like that and never can get them to wick that great haha. I'm more of a dripping kind of guy. Here's my dual coil setup for today on my Igo-W though it is only 0.8 Ohms, 9 wrap on a tiny screwdriver I got with my Fogger V3. It vapes great! Edit: 28g Kanthal A1

Here you go.

Nice! I'll have to give a go at twisted coils soon... it looks like a beast.

 

[ConradM]

Why twisted coils?

10 wraps each coil for the dual.

this sounds correct.
a few things to keep in mind.

the overall amount of wire will affect response time at a given resistance, and the fact that at the same resistance you now have each coil getting only half the wattage.

so in effect you now have twice the wire in the overall build to heat up with each coil only receiving half the wattage as the singe build.

as you have noticed slower response but more flavor - more wire = more surface area = more juice being vaporized per second = more nic and flavor.

I would raise the overall guage a little and cut the amount of wraps down some and the response time should improve if you can keep the resistance the same.

Something to try, wanted to try more surface area with reduced resistance.

,

For a dual coil setup, what would you suggest to get the max surface area, resistance around .5-.8, but no lag time? Is it possible with twisted wire and have no lag time? Should I go with a smaller diameter? Thx.

I've found with twisted coils they either give to hot of a vape or they take to long to heat.
