For electronic cigarette enthusiasts, a simple and powerful output device is all they need. They don't require complex features like temperature control, curve output, or TCR. Instead, they prefer a compact size for daily use. Combining these factors, it seems that only mechanical mods or box mods fit the bill, but their safety often raises concerns.

The R-KISS is currently the smallest dual-battery box mod on the market, featuring an all-metal body and a large color display. Its size is nearly at the limit of dual-battery designs, being only slightly larger than two batteries "kissing" together, which is likely the origin of its name. At the same time, it still offers a large color display and a practical large fire button, which is quite impressive! SMOK R-KISS Dual-Battery Box Mod Review The introduction of the R-KISS breaks the previous record held by the slim dual-battery Alien for over two years, setting a new benchmark for the minimum size achievable in dual-battery devices. So, what new delights does the R-KISS bring to users? Let's dive into today's detailed review of the R-KISS.

【Packaging and Parameter Testing】

The packaging of the R-KISS comes in a square box, predominantly black, with a real-life image of the R-KISS kit on the front. The color of the main image matches the actual product, which is a hallmark of SMOK packaging. The box is covered with a disposable plastic seal to ensure the product is intact and brand new upon receipt. SMOK R-KISS Dual-Battery Box Mod Review After removing all the packaging, the product list includes: 1 R-KISS main device, 1 TFV8 Baby v2 atomizer (with 1 pre-installed coil), 1 spare coil, 1 pack of spare leak-proof silicone rings, 1 MicroUSB charging cable, and 1 user manual with warranty card.

The R-KISS is impressively compact, with actual measurements of 125.7mm in height, 43.9mm in width, and only 27.5mm in thickness. For an 18650 battery, which has a diameter of 18mm, the width of two batteries would be 36mm and a thickness of 18mm. Compared to these parameters, the R-KISS's width is only 7.9mm wider, and its thickness is only 9.5mm more, all while maintaining an all-metal body and a color display, which is quite remarkable.

When compared to the previous generation SMOK Alien, the R-KISS is noticeably smaller, while still maintaining the strong quality feel of an all-metal construction, which is quite stunning.

The actual weight of the R-KISS kit is 184 grams, and with two 18650 batteries, the working weight is 274 grams, setting a new lower limit for dual-battery kits, making it very convenient for daily carry.

【Comprehensive Analysis of Appearance and Function】

The R-KISS kit continues to use an all-metal body, featuring a classic black and red color scheme, matte paint finish, and engraved lines, giving it a very nice overall texture—solid and robust. The front face features a large color display that occupies a significant portion of the device, with enlarged fonts for better visibility, and rounded corners for a comfortable user experience.

The upper part of the front panel is printed with the SMOK logo using a translucent method, and the top frame has been sculpted for added detail, enhancing the overall aesthetic.
SMOK R-KISS Dual-Battery Box Mod Review The +/- adjustment buttons and MicroUSB charging port form a playful expression resembling a little fireman, adding a lively touch. The +/- buttons are finished with a glossy piano paint, spaced adequately apart, and are of a suitable size, preventing accidental touches during adjustments.

The front features a square color display, centrally positioned, giving it a visually large appearance. The R-KISS main device only has a wattage adjustment function, and it does not even have a menu function, so the screen only displays simple information such as wattage, resistance, firing duration, voltage, and battery level. However, for a device with only wattage adjustment, this is sufficient. Pressing the fire button three times allows you to change the color of the main screen parameters, corresponding to the four colored dots in the upper left corner, switching to the respective theme color. Other than that, the R-KISS has no additional functions, making it quite simple. However, even with its simplicity, the R-KISS still retains balanced charging capabilities and comprehensive safety protections against short circuits, low voltage, timeout, no load, and reverse connection. Therefore, it can be said that the R-KISS offers more than a single battery mechanical mod in terms of powerful output, with a compact size comparable to mechanical mods, yet with safety protections that mechanical mods cannot match, which is quite impressive!

The side details showcase the craftsmanship that maintains SMOK's high standards, with segmented engravings that, while not necessary, add a nice three-dimensional feel to the side lines, demonstrating excellent attention to detail.

The back is designed to be largely symmetrical with the front but has been simplified. The bottom features the R-KISS model identification.

The side retains SMOK's signature integrated large fire button, which provides good tactile feedback, making it easy to operate blindly while holding the device. The red glossy paint finish complements the main black paint, giving it a stylish appearance.

The bottom battery cover returns to a push-to-open design, minimizing the overall size. It can be opened by pressing down and pushing outward, requiring a bit of force.SMOK R-KISS Dual-Battery Box Mod Review Opening the cover reveals a very compact battery compartment design. From this angle, you can see that the overall body is just large enough to encase two batteries, with the mainboard and screen compressed into this slim profile, showcasing a high level of industrial design. The bottom of the battery compartment features contacts for balanced power management, providing better protection for the batteries.

The top 510 connector is centrally placed, allowing for aesthetically pleasing compatibility with various diameters of atomizers. The negative terminal is a slightly extended stainless steel disc, while the positive terminal is a spring-loaded electrode, providing better compatibility with atomizer electrodes.

This time, the matched atomizer is still the compact and powerful TFV8 Baby v2, which can be refilled by simply unscrewing the top and features a locking mechanism to prevent accidental opening of the top cap.SMOK R-KISS Dual-Battery Box Mod Review In daily use, simply unscrewing it allows for easy replacement of the coil and cleaning of the atomizer. When assembling, it is also recommended to first screw the coil onto the base, then attach the glass tube to the top cap, forming two pieces before assembling the entire atomizer to avoid confusion and prevent breaking the glass tube.

The TFV8 Baby v2 maintains the TF family’s consistent simple style, with only five components: the mouthpiece, top cap, glass tube, coil, and base, making it easy for even beginners to operate.

Additionally, the TFV8 Baby v2 atomizer introduces two new TFV8 coil cores, with resistances of 0.17Ω and 0.2Ω, both designed for large vapor production, allowing the 200W output of the R-KISS to be fully utilized.

In terms of power testing, I used a power meter to measure the output power at the atomizer electrodes, and uploaded the data to a computer using a TTL real-time communication module to create a curve chart.

Measuring the maximum output of 200W, I used a 0.11Ω resistance and two fully charged SONY VTC4 batteries for testing, successfully achieving a maximum output of 202W. Due to the effects of direct current discharge, the power tends to decline over time. In a 10-second test interval (10 seconds is the safety protection duration for this device), an average output of 194W was obtained, aligning with its 200W power rating.SMOK R-KISS Dual-Battery Box Mod Review At the 150W measurement, the power showed slight fluctuations, but the overall average was accurately 150W.

At the 100W power level, the output still showed some minor fluctuations, but the average power was also accurate at 100W.

Overall, the power measurements indicate that the R-KISS outputs very quickly and directly, with no delay, and the power output aligns with its rated values, making it quite reliable for daily use.

【User Experience】

The first experience of using the R-KISS is its compactness—it's truly small! Of course, it can't be compared to pod vapes, but when compared to dual-battery kits, it is remarkably compact, even smaller than single-battery box mods from a couple of years ago. Additionally, the smooth edge transitions and large integrated fire button provide a very pleasant user experience.

In terms of functionality, the R-KISS adopts an extremely simplified built-in scheme, focusing solely on wattage output. Besides pressing the fire button five times to turn it on, pressing +/- simultaneously to switch theme colors, and single-clicking +/- to adjust wattage, it has even omitted the typical three-click menu function found in most devices, achieving a minimalist design. Its operation is very close to that of a mechanical mod with no features, yet it offers safety protections that mechanical mods cannot match, providing a user experience that is excellent for both new electronic cigarette users and seasoned ones who prefer simplicity!

With a maximum output of 200W, paired with the powerful new TFV8 Baby v2 atomizer, it is suitable for both smokers looking to switch and vapor enthusiasts, making it a versatile configuration. With this device in hand, you can enjoy vaping without worries.

In terms of drawbacks, after a week of testing, this easy-to-use kit does not have any particularly outstanding downsides. If I had to nitpick, I would say the materials could be a bit lighter; using lightweight aluminum alloy could reduce the weight further. However, compared to previous dual-battery kits, the R-KISS has made significant progress, so this point isn't a major drawback.

【Conclusion】

Historically, the greatest value of mechanical mods, aside from nostalgia, has been their powerful and simple portability. Although mechanical mods carry significant safety risks, some users still find themselves conflicted when faced with the size and complexity of box mods. The emergence of the R-KISS can be said to completely overshadow mechanical mods; it is compact, offers stable dual-battery output, comprehensive safety features, and extremely simple operation, making mechanical mods seem lackluster in comparison. If you're looking for something compact, powerful, easy to use, and safe, the R-KISS has it all—it's the smallest dual-battery kit you deserve!
