Introduction of RUBI KandyPen Review
The RUBI: a small gem. Meet the sleekest, tiniest, lightest vape we’ve ever reviewed: the RUBI, from KandyPens.
The RUBI KandyPen is a super compact and highly portable vaporizer with a refillable cartridge that handles thin oils, CBD liquid, distillates and e-liquids. At just 4 inches (10 cm) tall and weighing less than half an ounce (grams), the RUBI not only looks good it feels great in the hand too.
Out of the Box
Arriving nicely packaged, once removed from its box the RUBI charges fully via a Universal Micro-USB charging port in around 30 minutes. A tiny LED battery indicator lets you know when it’s ready for use.
The RUBI was specifically designed (patent pending) for Direct to Lung (DTL) inhalation in the USA, and hand-built in China. It’s sleek, and despite the insubstantial weight, feels well made.
Inside the Pod
The pod is a single unit mouthpiece and 1 ml. tank that slides out for filling. A tiny plug in the tank’s side pops out; it’s a little fiddly and whatever you’re filling it with, a needle-style nozzle will reduce spillage.
The OCELL ceramic coil heating element is wrapped in a Japanese cotton wick. The coil is 1.6 ohm and the battery gives you 8.5 watts of power, or 3.7 volts. This makes the RUBI actually pretty powerful for its size, and it kicks out a decent volume of vapor.
Filling it Up
I started with an e-liquid, since I had some on hand. I’m not a big juice user but it’s nice once in a while. With its fine nozzle, filling up from an e-juice bottle was mess-free.
The draw is air activated – so no power button – with dual airflow and air carb for instantaneous delivery. As long as the rubber plug is securely back in place the RUBI’s pods should not leak, and I experienced no spit back through the mouthpiece.
Small, Light Battery
The battery is 280mAh, so pretty small and light. I didn’t expect it to last forever but I’ve been getting between 30-50 draws per charge. Obviously, your mileage may vary depending on pull length and rip size.
Easy in the Hand and Pocket
I’ve dabbled with e-juice in the past, but I find the box mod style too bulky and am not a fan of tube-like pens. The ultra-light weight and flattened profile of the RUBI though, I’ve really taken to. It slips in a shirt pocket easily and easy to take a crafty puff on in situations where a regular vape might be too obtrusive. Importantly, I actually used it regularly!
Yes, it handles ‘noids
It you want to vape cannabinoid concentrates – and who doesn’t? – you have a number of options. You can mix a little wax with some liquid terpenes to achieve a useable fluid. Since terps are quite expensive not to mention hard to come by outside the USA, you could also mix a more sticky concentrate with some propylene glycol (PG) blend.
I got hold of some oil thin enough to use directly. If you can only get the more viscous stuff, you’ll need some PG – or dilute it with some e-juice. Since I only had one pod and that already contained e-juice, that’s what I did: made up an approximately 70-30 mix of oil and juice. It worked very nicely, thank you very much. Spare pods are available and recommended if you want to swap between vaping liquids
The RUBI looks quite similar to a more expensive system put out by a popular US herbal vape maker (our review is underway…) that uses pre- filled proprietary pods. All fine in the USA, but hard to get elsewhere. Plus more expensive and not as customizable to your own vape liquid wishes as the relatively inexpensive RUBI.
Low-cost Open System
With its low cost, great looks, simple operation and open system pods, the RUBI is a great addition to your vaping options. There’s also a lifetime warranty on the battery.
