What are some reasons why my mech and RDA aren't really performing as expected?

Hey everyone, not sure if it's rda related or mech mod related but I figured I'd check here and see if anyone can help me.

So I got my first mech mod yesterday, the smok Magneto V2 and it's awesome and everything so far, but I feel like it should be performing better. When I tested a freshly charged vtc4 on my multimeter it read that there was very little voltage drop (. 08 I think, which seems small to me) so I thought it would be making some steam. But it hasn't really been which has me a bit confused.

It could be my build, which is dual 25awg kanthal in my Hobo V2.1 reading at .5 ohms. This build used to take too long imo to heat up on my ipv but I thought the mech might be able to handle it. It definitely heats up a little quicker, but I feel like there is something else wrong with the mech and I might be losing voltage or something...

I cleaned the positive and negative contacts with an alcohol pad before assembling, and made sure it was a tight fit on the battery as it's a telescoping mod but maybe I'm missing something?

I'm gonna put a freshly charged vtc4 in and try to break in the coils/wick a little more in the meantime, but if anyone has some tips or advice I would appreciate it!

Check to be sure all your screws in the atty are tight.
Also check the positive pin on the mod to be sure it's making good contact.

These are first two things I check when I feel something isn't right with my vape.

Clean all the the threads really good especially if its a telescop.

, 25g? Bet there is a lot of wire in those coils, in dual mode thats only 16w per side and its going to take a lot to heat up a slab of low resistance wire.

Cut the amount of wire in half, using 28, 29g for same resistance. And it will work much better.

Yeah you got about 1/2 the available wattage/voltage you will need to power that coil you built. Way too much metal for a 3.7 volt battery to heat-up without a boost.

I have a dual 3.0mm coil setup on my Mut X V3 with 24 gauge wire, coming out to about 0.3 ohms...and it fires up nice and fast and chucks the clouds big time.

You're going to want more like 6 amps going through 25 gauge

Kanthal A1
gauge ----- watt per ohm (per coil) for 200mW/mm2
34 ----- 1.4
32 ----- 3
30 ----- 6
28 ----- 10
26 ----- 23
24 ----- 45
22 ----- 91
20 ----- 182

Current might be a more intuitive way of thinking about it.

gauge ----- current (Amps) for 200mW/mm2
34 ----- 1.2
32 ----- 1.7
30 ----- 2.4
28 ----- 3
26 ----- 5
24 ----- 7
22 ----- 10
20 ----- 13

18W per 1-ohm coil.... that's pretty lukewarm for my tastes. You'll see a substantial difference getting each coil closer to 0.7-0.8 ohm (22-25W per coil), for an overall build resistance of 0.35-0.40 ohm.

Your definition of slow is way different than mine.. I don't use thicker than 28awg because of the slow heating times.

I wrap similar to javyn, and the added flavor/density I get with 24 ga over 28 ga and thinner is well worth the ever so slightly slower ramp up/down time. Every atty I've compared the two gauges says the same thing.
