Got my KR8 … Uhm?

[AlexTM]

Hello there!

I got the KR8 I ordered because I wanted to see what the fuss is about. Otherwise, I am very happy with my 510 and the occasional 901, thank you very much.

As I had never tried a KR8 before, I have a question: The vape out of that thing is so hot, it nearly burns my lips and tongue. In fact, if I vape it for more than a minute, it does burn them. I am fairly certain that is not exactly how it is supposed to be, but I thought I'd better ask.

Also, is there a youtube vid that shows how to refill the cartomizer with a syringe? I believe there are three methods, opening it, syringe, and dripping into the lower hole. I saw the first and last method, but no syringe. Did I miss any?

Thanks,
Alex

Are you doing the slow drag? These work a little different than the 510.
You sure can fill with a syringe. Pop the cap and o ring, push syringe down into batting, slowly releasing juice.
Or you can try the Taryn method, which is very easy, and is on the sub-forum for V4L.

Here's a video on the basic syringe refill technique: YouTube - How to refill a Cartomizer

I use 0.5mL when topping off this way, but Leaford at V4L posted recently that he uses 1mL.

It got too hot for me also, I took off the round end cap and o-ring inside and use a 901 tip.
Makes re-filling easy too.

Are you using prefilled carts? I've only experienced hot nasty vapor when I was vaping a dry cart. As for the cart being too hot, is the sticker on it or is it just metal? The stickers on the carts make a huge difference in how hot the outside of the cart gets.

Can't chain vape the same cartomizer either. Take a few puffs off one and rotate. I was keeping about 7 on rotation at a time. Do not let them get hot and keep filled. I personally don't like the battery-end dripping method...This will kill auto batts if you are using them.

Weird experience your having. My wife and I pretty much chain vape our carts till they dry out. Then we drip in the battery end until the atty dies. And the only thing that has killed our auto batteries is time.
I will concede that way back when we first started using the cartomizers, some did seem to get hot, but thats an issue that we havent delt with in a long time. I would consider where you're getting your carts from. Maybe they're just poor quality??

Randyrtx, thanks for the link, had not found that one, and I wanted to try various methods of refilling.

The cartomizer was an empty one, always safer in Germany to order no liquid whatoever with hardware. Also, that way it is easier to compare tastes. I filled the cartomizer by removing the top, and dripped (slowly, evenly spread) 21 (fairly smallish) drops of liquid into the filling, and put the top back in. Instructions usually say 18-20 drops, or about 1ml capacity, which should be around 20 drops. (It's 21 because it is 2/3 KML and 1/3 Cappuchino.)

It's also not so much the cartomizer itself that gets hot - my 510ers get considerably hotter. It's the vape itself, after the first or first two drags, that is so exceptionally hot that I cannot vape on. I also always vape rather slowly, at least when I am at home. And the battery is a manual, so even if I'd overfill (which I don't think I did) it could not damage the battery. I've right now tried three puffs which were exactly 5 seconds, with +10 seconds between puffs, and even the first one was quite warm, and the third one definitely too hot.

And carts are from heaven gifts, so quality should definitely not be an issue.

Yeah, refill them through the battery end. You'll learn to know how many drops you need to avoid flooding.

 

[AlexTM]

Actually, I don't think I will do much refilling if I can't vape them because they burn my mouth. So, my most important question again: Is it in any way normal that the vapour itself is that hot? Or is it a known problem, preferably with a solution?

 

[YKruss]

I've heard that you can use modified 901 wistle tip cartridge on cartomizers, try to search it.

Also if you have them, 901 wistle tip, on hand - experiment.

 

[Randyrtx]

I don't think it's normal for the vapor to be that hot. I've noticed that the carto itself will get uncomfortably hot if the coil isn't properly centered, it's concievable that the vapor could also overheat if the coil isn't fully surrounded by sufficient batting.

 

[Scottbee]

You don't want the cartomizer to get hot at all. And frankly, once it does get hot.. it's probably shot. The coil will melt/burn the poly wrap and filler.. and then they just don't work right anymore.

DISCARD.

Recently got one too; don't notice 'hot vapor'. In fact, I'm not getting much of anything at 18mg in the stock flavor except vapor.

Where did you get your kr808 from? You seem to be the very rare one with a problem of this sort. My cart gets warm, not hot. And I don't think it is a common problem.

Is it hard to draw from the cartomizer?

One thing a lot of new users overlook is where the tape is on the cartomizer. If you don't see the metal ridges on the bottom of it then the tape is covering the air holes causing the cartomizers to overheat. A few of my first cartomizers were like that and I thought they were duds before I realized it.

 

[AlexTM]

This is where I have the cartomizers from. I have never had a quality problem with anything from them, and nobody else I know had one, either. (Lots of people in the German forum order there.) That does of course not rule out a bad cartomizer, but it makes a general problem somewhat unlikely.

I tried the 901 whistle tip, have some of those, although I prefer the normal flat ones. Funny result: I did not expect any improvement, since really hot vapour would hardly cool on another half inch. But not only is the vape very cool now (and I mean "very" as in "probably too cool"), the cartomizer starts to gurgle!?! Put the original top back on, scalding hot vape. Whistle tip again, lots of cold vape, gurgling noises, and very hard to draw. I sincerely hope this is not standard KR8. Tried the same again, same result. At least that rules out a problem with the battery.

I guess I'll have try a second one. Another ml of perfectly good juice

The coil, btw, was properly centered. Checked that because one of the Youtube vids I did find mentioned it. I also do not get even a slightly burned taste, and the filling looks OK.

Edit (no need for another comment that quickly): Just filled a 2nd cartomizer. Well, it does not get scaldingly hot like the first one, but still quite warm. (Tried more 5s dar + 10s pause.) Will check more tomorrow, somehow, I don't taste things properly tonight.

Sol-Blackguy: By "metal ridges" you mean the 4 air holes at the bottom of the cartomizer? Those were indeed partially covered, I pushed the paper down with my thumb, and there may have been a slight improvement. Was not checking too thoroughly, because the vape was still pretty hot.

 

[Randyrtx]

"Scalding" hot is definitely not normal, but I have found the vapor to be far warmer than on a 510. That was in fact one of the first things that struck me about cartomizers when I first started using them.

yep, I like the hot vapor.
I had one that did get to hot and it was because the holes were partially covered.

 

[AlexTM]

Well, I partially removed the paper around the cart, for maybe 2mm. And I blew through that cart, because somebody told me it might be liquid in the middle. Did both help a little bit, so I can only suppose there are several small things wrong with that one.

The second cartomizer also gets very warm, but nowhere near that hot. Vaping that is not a problem, but I'll postpone testing taste till tomorrow.
