The KandyPens Rubi is a particularly compact pod system for thin oils and e-liquids — importantly: for oil, not for thick wax or shatter. Instead of loading a coil, you fill a refillable 1-milliliter pod that vaporizes via an OCELL ceramic coil with 1.6 ohms and a Japanese cotton wick, and is built leak-proof. The Rubi is draw-activated and works entirely without a button: you simply draw on the mouthpiece. There is no selectable temperature — the device works with a fixed, temperature-regulated output of around 8.5 watts at 3.7 volts. The small 280 mAh battery lasts around fifty draws and charges over Micro-USB in thirty to eighty minutes. The Rubi targets users looking for a tiny, uncomplicated pod device for oils.
The KandyPens Rubi is a pod system built specifically for thin oils and E-Liquids, not for thick wax or Shatter, which does not work well in an oil pod. Instead of loading an open coil, you fill a refillable 1-milliliter pod. Inside it is an OCELL ceramic coil with 1.6 Ohm and a wick made from Japanese cotton, which vaporizes the oil evenly. The pod is designed to be leak-resistant, making it suitable for everyday use. Because you refill the whole pod and do not handle a sticky coil, operation is clean and simple.
Draw-activated with no button
The Rubi is deliberately kept simple: it has no button, but is activated by drawing (draw-activated). You simply draw on the mouthpiece and the device vaporizes; nothing to adjust, nothing to press. There is no selectable temperature. Instead, the Rubi works with a fixed, temperature-regulated output of around 8.5 Watt at 3.7 Volt, tuned for thin oils. This makes operation as simple as possible, but also means the intensity cannot be adjusted; anyone looking for degree-precise control is in the wrong place with the basic Rubi.
Battery, distinction and target group
The 280-mAh battery is small and lasts for around fifty draws per charge; charging is via Micro-USB in thirty to eighty minutes. According to KandyPens, it offers a Lifetime warranty on the battery. When buying, you should pay attention to the exact model variant: the basic Rubi has no temperature control, while the Rubi Twist offers variable voltage; there is also the Rubi Slim and various editions. For users looking for a tiny, uncomplicated and discreet pod device for thin oils and who do not need temperature control, the Rubi is well suited.
