I have a KR808-D one manual XL battery and one automatic. I have been using the regular cartomizers that I get from myvaporstore. Been off analogs for 6 weeks and love the vaping experience and my KR808 would be fine if it held more juice, but...im tired of filling so much and dont much like the burnt taste that comes out of nowhere like...suprise! its empty! Gross! Also I have to take long hits back to back to be satisfied. Is it time to upgrade or is there something I can buy that will fit what I have?
There are better KR808 cartomizers, but the one's I use are still "small" (Bloog MaxxFusion).
There are also larger KR808 cartos, but most of them tend to have mixed reviews on the quality (clearomizers, and such).
If you're not looking to carry a bunch of already filled cartos (which is my preference), then you're probably ready to move up to a larger device. KR808's are small by nature, and that's often one of the primary reasons KR808 users are drawn to them, so sticking an adapter on it, and then adding a massive carto would be a bit goofy (though it could be a cheaper temporary solution).
The Leo, the i-go, and the go-go, all have large carto options. In the 510 style there are moderately large "XL" cartos offered that are quite good, and even larger cartos than the "XL" size. A 510 "ego" setup would be the least expensive, and most versatile move.
