I got that info by doing research. I said that the 3000mah rating is legit (around 0.4A-1.2A draw), not that it's the top notch battery for E-cigarette use. Keep in mind that 18650's are more commonly used to power LED flashlights, not E-cigarettes. If a battery isn't good enough for you, then don't buy it but don't rag on my recommendation, ******-bag.
