Oil-and-coil separated structure: ESUN pod vape experience

In China, smokers account for a significant proportion of the global population. Whether in social settings or business etiquette, offering a cigarette is often the first step to starting a conversation. Giving cigarettes as gifts is also a common way to establish relationships among smokers in China. However, since the rise of pod vapes in 2018, many have opted to gift electronic cigarettes instead.

Today, I would like to share a pod vape called ESUN (益爽). Unlike many popular pod vapes on the market, it promotes itself with the slogan of "0 nicotine content cartridges" and the gimmick of "edible capsules"... Regardless of the various marketing strategies employed by different brands, each is merely trying to find a breakthrough during this oversaturated product period. One of ESUN's breakthroughs is its "oil-and-coil separated technology"...

The device measures 94.2X10.5X8.5MM and uses a built-in 350mAh battery, which takes 30-45 minutes to charge via a standard mini USB port. Although it promotes "0 nicotine content cartridges," the actual packaging still includes two cartridges with a 5% nicotine concentration (menthol/tobacco), while the "0 nicotine" cartridge has a slightly cool loquat flavor.

The body features a skin-like surface treatment, providing a good grip. This pen-shaped portable vape design has become mainstream among electronic cigarettes. The cartridge shown above is in an unopened state, revealing a milky white silicone sealing valve at the mouthpiece. Next, let’s take a look at this "oil-and-coil separated cartridge"...

Before use, the milky white silicone column must be removed from the cartridge, and it should be left to sit for a few minutes before use. Although many manufacturers have already adopted silicone sleeves for cartridges, they do not completely isolate the atomization core from the e-liquid. ESUN's method effectively prevents oil leakage during transport due to pressure changes.

The connection between the cartridge and the body uses a "male/female" combination link, sealing through the protruding silicone and the recessed part of the cartridge. This combination creates a more reliable airtightness, activating the pneumatic switch, making the ignition process more sensitive and concentrating the condensation for easier cleaning.

The connection between the cartridge and the body is not the common magnetic type; instead, they are secured through a protruding and recessed design, ensuring a stable connection. The lines at the cartridge's mouthpiece are clearly designed for mouth-to-lung users, targeting those looking to quit smoking or switch from traditional cigarettes.

The two nicotine-containing cartridges do not stand out much, featuring familiar tobacco (cured tobacco) and menthol flavors. The loquat-flavored "0 nicotine" cartridge tastes like loquat throat lozenges. In actual use, the difference between 0% and 5% nicotine is quite significant; indeed, "0 nicotine" does not provide any sensation of relief from cravings.

The "edible capsules" indicated by the manufacturer are not included in this experience kit. The tight draw of the cartridges fits well with the habits of users looking to quit smoking, while the honeycomb ceramic core structure provides a clean and pure e-liquid flavor and taste. ESUN is similar to various other pod vapes on the market, with the only highlight being its factory-sealed cartridges, which is a reliable design for frequent travelers who need to fly...
