When to replace pre-built coils

[Bulldog]

Coils you just know when needing to replace, I have my atties not used as often that could go months and others after a month need replacing. You get to know when you not getting the best from the coil. As for rewicking every 2 days on my Kylin Mini or Intake whichever one is in daily use at the time which equates to 60 to 80 ml of juice so as a general rule I would say I rewick after 60ml of juice in any RTA,RDA or RDTA.

Rewick get to me depends on the juice very much. My '''heavier" juice like my Lemon Tart fouls the wicks really quick. The fruity stuff not nearly as quick.

I am still quite new at this but the Geek Vape nichrome claptons lasted about a month whereas the twisted Kanthals have been going for much longer. I had to replace the nichrome claptons this week as they just did not taste spot on anymore with some harshness. I suspect the Chinese wire had something to do with it.

I replace them with DIY twisted Nichrothal coils and will see how long they last.

So I'm still new to whole rebuilding thing.

How do I know when to replace the coil?
What I do now is just dry burn the coil clean before rewicking and I do a strip down of the tank when I see it starts looking dirty and use a tooth brush to clean everything.

Read somewhere one should change the coil when the resistance starts to change. Is this the sign?
Or is it once the coil starts showing hot spots that don't go away with some repositioning/ strumming?

Hi @franshorn

Coil life depends on several factors

• Power you vape at
• The juices you vape
• What the coil is made of and the quality of material

For my basic coils that I make myself (simple round wire, not exotics - mostly Kanthal and NI80) I find it lasts me at least 3 months, even as much as 6 months. I don't vape exclusively on one device though. I find the coil doesn't feel 100% right and gunk build up makes marks on the coil even when dry burning and cleaning etc. Sometimes hotspots too. Then its time to build a new coil. But this happens gradually and I don't really notice the drop off in the vape. I am often surprised how much better the vape is when I make a new coil. Fires with more vigour and "purrs". Perhaps if I got into the habit of building new coils more frequently I would notice it more, lol.

As for the exotic coils, obviously one wants them to last longer, especially the custom ones you buy from coil specialists. I havent got a lot of experience with that - I only have a few coils from Smiley and had one from The Coil Company. My Coil Company coil was in my Billet Box and it lasted very long. About six months. I only changed it because I thought I should but not really because I noticed any degradation in the vape.

I think juices and power also play a role. Dark juices and those that gunk up the coils and wicks tend to make my coils last less long. I generally vape at lowish power - but the higher the power the more stress on the coil so I would imagine that high power vaping reduces coil life a bit as well.

Oh BTW that Asvape Gabriel mod is R3200...

Anyway back to the original topic coils...

It all depends on the quality - some last longer, others are crap.
