Compatibility: The KandyPens Rubi is compatible with e-liquids, nicotine salts, and oil extracts.
At four inches tall, the Rubi is a little taller than most e-cigs but still small enough to be easily carried around. It is similar in design to most e-cigs in that it looks a little like a USB stick. However, the Rubi has a smoother, more rounded design that’s quite attractive, plus there is a nice range of color options to choose from. The Rubi feels comfortable in the hand, and inhaling from it feels good as well because of its rounded mouthpiece.
When it’s time for a refill, removing that mouthpiece is simple and refilling the pod is relatively easy as well. One design shortcoming is that there is no viewing portal, or similar feature, that allows you to monitor the level of e-liquid left in the pod. You either need to remove the pod from the battery to check, or you have to wait until the flavor goes off. Neither of those options is ideal, but in the long run, the inability to check the oil level while the pod is connected to the battery is a relatively minor problem.
Since the Rubi is an open pod system vaporizer, it can be used with a variety of different vape liquids. It can be used with e-juice of course, but you can also use nicotine salts and even liquid oil extracts with the Rubi. So if you want to use a different kind of oil than what you can get in a pre-filled CBD cartridge, then you can do so with the Rubi.
It’s important to prime the Rubi pod before step 4, this is a very short, quick process. Simply inhale from the mouthpiece 3-5 times before moving on to step 4. Skipping this step will result in dry hits and you definitely don’t want that. You only need to do this once per Rubi pod.
The Rubi is draw activated and has a low draw resistance so it is pretty easy to use.
Needless to say, the flavor of the vapor depends on what type of e-liquid or oil you use with the Rubi. But regardless of what you use, the Rubi will do a good job of vaping it, particularly with e-liquids and nicotine salts. When it comes to oil extracts, the performance of the Rubi is very good, but it can’t match a good oil vaporizer like the PCKT One Plus because it lacks voltage control, and therefore doesn’t have any customization options.
If you love big clouds, then you will definitely love the Rubi because it produces some huge clouds, not as much as a vape mod, but certainly more than any other e-cigarette.
The Rubi has a 280 mAh battery, which is one of the more powerful e-cigarette batteries available. It is good for about 250 puffs before it needs to be recharged. When it does need to be recharged, it only takes about eighty minutes. The Rubi uses a standard micro USB cable rather than a proprietary charger, so replacing it or buying a spare is easy.
