Im looking for a good one that would work on my itaste svd.
Bigflyrodder's comments are well stated... to safely use an RDA, one must be aware of the parity between coil(s) resistance and the available amperage of a power supply. Only one of the "facets" in Ohm's Law formulas.
For example, your SVD has a 5 amp "safety" limiter built into it's microprocessor. Than means, following Ohm's Law, at the maximum power output of 15 watts, the lower limit of resistance before peak performance and parity go "upside-down" is 0.6Ω. You can happily vape at resistances at or above that... but to go below is to no advantage.
Another example... made practical and easy by using
"Steam Engine", the interweb coil modeling calculator.
A single 28 gauge Kanthal wire coil, with 10 "wraps", built on a 2mm mandrel will produce a resistance of 1.0Ω. Two of the same coil, because we must use 1/4th the gross resistance of the two coils combined... would have a resistance of 0.5Ω.
If the above scares the crap out of you... maybe rebuildables aren't your cup of tea. If on the other hand, you are utterly fascinated... welcome to the club, brother. ;-) The hyperlink found in my second sig line may be of interest to you.
