Vaporesso’s Xros line has a new tiny pod mod – the Xros Cube. 

This pint-sized vape kit measures just 27.8 x 24.9 x 72mm, making it one of the smallest pod devices available.  

Despite its compact size, it still has a built-in 900mAh battery and uses the flavor-optimizing COREX heating tech in Vaporesso’s flagship devices. 

The Xros Cube is designed specifically for mouth-to-lung vaping with replaceable 2ml pods available in 0.8Ω and 1.2Ω resistances.

It features a top-fill pod design for easy refilling without leaks or messes. An LED battery life indicator and automatic draw activation round out the straightforward feature set.The XROS Cube is available in 8 colors: Black, Grey, Silver, Ocean Blue, Cyber Lime, Sakura Pink, Bondi Blue, and Forest Green.

The Bottom Line

The Xros Cube might be the smallest vape device I’ve ever tested, but it still delivers a fantastic vape experience. Thanks to the adjustable airflow, the Xros pods work as well in the Cube as any other Xros device. It delivers fantastic flavor and a consistent draw. It lacks adjustable power, but that’s a worthy omission for such a stealthy compact device – recommended.

Design & Build Quality

At first glance, the Xros Cube definitely lives up to its name – this thing is cubic! 

The body is a rounded rectangle, with dimensions of 27.8mm in width, 24.9mm in depth, and 72mm in height. It fits comfortably and ergonomically in the hand. 

The plastic body keeps it lightweight at just 46g, so you barely notice it in your pocket. 

It comes in a two-tone matte color finish. The review unit I tested was the Forest Green, a striking teal and deep green mix. The colors really pop, and it’s an attractive little device with subtle branding. 

The duckbill mouthpiece sits slightly off-center, an interesting visual choice. Since the side opposite has the lanyard attachment, it took some getting used to, which orientation felt natural when vaping. The metal lanyard connects solidly for securely wearing around your neck if preferred.

There is little wiggle room with the strong magnetic connection between the pod and the battery. It holds securely with no accidental detachments. The battery cap snaps in place tightly.

The pods themselves have transparent windows so you can monitor juice levels. The plastic does have a slight tint, but the juice level is still visible. Older Xros pods can get cloudy after multiple refills, but these stayed reasonably clear.

Charging utilizes a USB-C port. Due to the petite size and rounded shape, the device must lay flat while charging instead of standing upright. This helps keep the smooth lines vs having a port break up the side.

Rather than incorporating a screen that would impact size and battery life, there is an LED light indicator for battery level. A neat trick Vaporesso implemented reflects the light internally so you can readily see it from multiple angles, even when actively vaping.

Buttons or settings would also add unnecessary bulk, so the operation relies on automatic draw activation. This works flawlessly, triggering immediately with either a tight or loose MTL inhale. 

One feature the Xros Cube does have is adjustable airflow. This comes courtesy of a slider on the base beneath the USB-C port. The slider has a good restriction, so it stays in place and allows for all stages of MTL vaping.

The simplistic feature set allows impressive miniaturization without losing performance capabilities. 

Overall, the construction feels sturdy and durable. For a tiny pod vape meant for on-the-go use, the Xros Cube seems up to the rigors of daily pocket carry.

Features & Functions

Despite its small size, the Xros Cube still boasts an impressive 900mAh battery capacity. 

While the low-power mesh coils aid efficiency, a battery this size lasting a full day of heavy vaping is impressive. 

An internal LED indicates the remaining battery life via a color-coded system. 

• Green = 60-100% 
• Blue = 30-60% 
• Red = 0-30%

The light reflects internally to make it viewable from wider angles. However, at steep angles when actively vaping, it can still be tricky to catch a glimpse before it shuts off a few seconds later.

The Xros Cube uses the same COREX flavor-boosting technology found in all recent Xros devices. Flavor reproduction from the 0.8Ω and 1.2Ωmesh coils is genuinely impressive, especially for a mini pod system.  

Despite the lack of buttons, the draw activation provides consistent firing. The MTL inhale triggers instant vapor production thanks to the near-instant heat-up time. There is no delay or ramp up, even with successive puffs.

The Cube features an adjustable airflow slider. It allows the draw to range from a very tight MTL when closed off to a loose MTL fully open. 

The device has a USB-C port for charging and comes with a USB-C cable included in the kit. It charges at a 1A charge rate, and its 900mAh battery tops up in under an hour.

Pods/Coils

The Xros Cube comes with two pod options in the kit – a 0.8Ω mesh pod and a 1.2Ω pod. 

The pods have a 2ml juice capacity, refillable via the convenient top-fill method. Simply remove the mouthpiece to expose the fill port. 

Both the fill hole and opposite air vent are visibly marked with red seals, so you know where to fill without introducing leaks. 

The anti-leak system routes any overflow or displaced air through internal channels. After filling, pop the mouthpiece back on, let it sit for 5 minutes, then it’s good to vape.

The pods are made of transparent plastic, so the e-liquid level is easily visible. 

The 0.8Ω mesh pod caters more to flavor. The draw wavers between a medium to loose MTL. With the 1.2Ω pod, the draw is a slightly tighter MTL. Both deliver surprisingly dense, saturated vapor for mini pod coils.

I found both pods worked well across various juice types from 50VG to 70VG ratios. 

Flavor popped nicely, and I experienced no dry hits or seeping during testing. The pods lasted roughly 10 refills before the flavor started to decline.

Performance

Having tested many Vaporesso Xros pods in the past. I knew what to expect from the Cube, and it didn’t disappoint.

The Xros pods are some of the best pods on the market for flavor and consistency, and they perform just as well in the Cube as in any other Xros device.

Depending on pod choice and inhale strength, the draw can vary from a tight MTL to a loose MTL. At a push, you might be able to get a restricted DTL with the 0.8Ω – but I consider it a solely MTL device.

Both pods deliver extremely satisfying flavor for their size. The vapor is saturated and pushes through all the nuances in my favorite vape juices. 

The adjustable airflow works well with both the 0.8Ω and 1.2Ω pods. 

Out of the gate, the 1.2Ω pod has a similar draw to the Caliburn G. But adjusting the airflow can get you a true tight MTL or more loose draw.

The 0.8Ω pod has a notably looser draw, falling around the same as the Geekvape Wenax K1. It produces a slightly warmer vape with more dense vapor.

While both are excellent pods, I preferred the warmer and slightly punchier 0.8Ω pod. 

Having tested Xros pods before, I know they hold up well with thicker juices. Still, I tested some 70VG, and it wicked efficiently with no leaks or dry hits.

Also, chain vaping caused no flooding issues or noticeable heat buildup. 

The automatic draw is flawless, just like all other Xros devices. It triggers instantly when taking a pull – no delay whatsoever. 

I hate having to pull harder on some devices after the battery depletes a bit, but the Xros Cube fired consistently after a full day of heavy use.

As far as battery life, getting nearly a full day from a 900mAh battery definitely impresses. Obviously, at higher power with the 0.8Ω pod, it drains faster. But even pushing 14-15W lasted from morning til evening for my use. 

When I tapped out for the night, the 1.2Ω MTL pod was still going after 250+ puffs. 

Overall, whether used as a secondary device or exclusively for stealthy, portable use, the Xros Cube fires on all cylinders. The flavor production and vapor density stand alongside pod mods triple the size.

Verdict

The Xros Cube proves good things do come in small packages. 

Despite dimensions similar to a pack of gum, it delivers a vape experience as good as all other Xros devices – which is great. 

MTL vapers will appreciate that Vaporesso includes two different resistance pods. 

Those seeking a tighter draw and less battery consumption will love the 1.2Ω pod. While the 0.8Ω delivers a warmer vape with more pronounced flavor (at the cost of more battery drain). 

Either way, they are both excellent MTL pods, and the adjustable airflow will allow you to find the perfect sweet spot for your MTL draw.

While I’m a little disjointed, the Cube only has 1A charging. The 900mAh internal battery does an excellent job of lasting the day.

For those seeking a stealthy yet mighty pod vape for on-the-go, the Xros Cube is hard to beat. Its simplicity also makes it ideal for new vapers transitioning from disposables.
