With the increasing variety of products in the e-cigarette market, many consumers easily fall into the misunderstanding of “prioritizing appearance” when purchasing, but ignore the key indicators that determine the user experience and safety. First, pay attention to the material of the atomizing core – high-quality products mostly use ceramic atomizing cores, which have strong high-temperature resistance, are not easy to produce harmful substances, and can better restore the flavor of e-liquid. Second, battery safety: lithium batteries with overcharge protection and short-circuit protection can greatly reduce the risk of use. Finally, the composition of e-liquid: choosing e-liquid with clearly marked nicotine content and no heavy metals or harmful additives is the basis for healthy use. Screening through these three indicators can effectively avoid inferior products and find the e-cigarette that really suits you.
