Vaporesso Coss Review: The First Self-Charging and Self-Filling Vape

Through most of the history of vaping, you could safely say that if you knew how to use one product, you essentially knew how to use all of them. There are differences between devices like vape mods, pod systems and disposable vapes, but the similarities outnumber the differences in most cases.

Once in a while, though, a product appears that’s truly unique – and you can certainly use that word to describe the Vaporesso Coss. This is a device that’s capable of recharging and refilling itself with the included battery-powered hub, which is something we can safely say we’ve never seen before.

The Vaporesso Coss is a completely different type of vaping device, and it warrants a completely different type of review. Rest assured that we’ll explain all of the details on this page.

As you’re about to learn, the Vaporesso Coss solves some unique pain points and definitely has specific use cases that make it a very compelling product.

At the same time, though, the Coss also has some drawbacks that will make it less than ideal for some people and situations. Because the Vaporesso Coss is a very unique device with brand-new technology, it’s much more expensive than all of the best vapes while offering somewhat sub-par performance. Also, the Coss isn’t an entirely self-filling device because you do still need to fill the main e-liquid reservoir periodically.

So, is the Vaporesso Coss worth buying? We’ll walk you through the most unique vaping device to hit the market in years. By the time you’re done reading, you’ll have a better idea of whether this is the right vape for you to buy.

The Charging and Filling Hub is the Defining Feature of the Vaporesso Coss

Instead of beginning this review with a standard bullet list of the product’s features, we’ll go straight to the main feature that makes the Vaporesso Coss what it is: the portable charging and filling hub. The hub has a 1,500 mAh battery and a 7.5 ml e-liquid reservoir, and it also stores the Coss device. The hub has the ability to recharge the Coss device up to six times, and the 7.5 ml reservoir can refill the device’s 0.6 ml pod about 12 times. Given the hub’s large battery and e-liquid capacity, many people will find that they can vape for several days at a time without worrying about the system’s battery or e-liquid level.

When you’re not using the Vaporesso Coss, the hub stores the device and feels a bit like a cigarette pack in your pocket, although it’s noticeably heavier.

If you’ve been vaping for a long time, you might remember how many of the early cigarette-shaped devices came with packs that provided portable battery charging and also stored extra cartridges. A portable charging pack was of limited usefulness, though, because you couldn’t just throw your e-cigarette into the pack to charge the battery. Instead, you’d have to remove the cartridge and connect the battery to the pack’s charging port and reverse those steps when you wanted to resume vaping.

The Vaporesso Coss solves that problem – just slide the device into the hub, and it begins charging immediately. When the device is fully charged, the hub turns off. You don’t need to do anything.

The portable charging packs of old also didn’t have any refilling features at all – that’s something completely new.

The hub has its own removable e-liquid reservoir, which functions a bit like a pod without a mouthpiece. When you press the button on the side of the hub, a vacuum pump automatically injects about .2 ml of vape juice into the device’s pod. The process takes around a minute.

Since you’ll be storing the Vaporesso Coss in the hub when you aren’t using it, the device doesn’t need to have a large enough battery for all-day vaping. The battery in the stick portion of the device is only 250 mAh, and the device is just 9 mm thick. It’s easily one of the smallest vaping devices on the market and is probably the most cigarette-like pod system in terms of size.

As fun and unique as it is, the Vaporesso Coss does have some drawbacks that you’ll need to consider as you make your purchasing decision. We’ll discuss those at the conclusion of this review.

The Vaporesso Coss Also Has a Very Unique Pod

Although the hub constitutes the majority of what makes the Vaporesso Coss unique, it’s also worth mentioning that the Coss comes with two different pods – and one of them is quite unique.

In addition to the standard pod, the Vaporesso Coss also comes with an alternate pod that accepts a cotton filter tip. The device includes six filter tips in all, and puffing on the soft tip makes using the device feel very much like smoking a cigarette.

Both Vaporesso Coss pods have built-in 1.2-ohm mesh coils. Although this device won’t compete with most other refillable pod systems in terms of vapour production, you should find it more than satisfying as long as you’re using a high-strength e-liquid.

What Pain Points of Vaping Does the Vaporesso Coss Address?

The Vaporesso Coss is a very unique vaping device, and that means it addresses some specific needs and pain points that may or may not apply to you. These are the main use cases for this device.

• It offers some of the convenience of a pre-filled device along with the lower recurring costs of a refillable device.
• It partially eliminates the mess of refilling your vape since you only have to refill the hub’s reservoir occasionally.
• The Vaporesso Coss is one of the only pod systems that you can hold between two fingers like a cigarette. A cigalike looks and feels even more like a cigarette, but the Coss has better vapour production since it’s a bit bigger.
• The Coss eliminates the need to carry a bottle of e-liquid wherever you go, since the reservoir holds more than enough vape juice for a full day.
• The Coss also eliminates battery anxiety and the need to have a charging cable available. If the hub is fully charged, there’s virtually no chance of the battery dying while you’re out and about.

In all, the Vaporesso Coss eliminates or at least mitigates many of the inconveniences and pain points of the other types of vapes currently on the market. Some of these features do come with significant caveats, though, and we’ll discuss those in greater detail at the conclusion of the review.

How to Use the Vaporesso Coss

By now, it’s definitely very clear to you that there are no other vaping devices like the Vaporesso Coss – so regardless of your level of vaping experience, some aspects of this device will certainly be unfamiliar to you. We’ll provide a walkthrough here.

How to Charge the Vaporesso Coss Hub and Device

To charge the Vaporesso Coss hub, connect it to your computer using the included charging cable. The hub is fully charged when all four LEDs are solidly lit. The device charges automatically when it is inserted into the hub. While the device charges, the LEDs on the side of the hub will pulse. The lights change from pulsing to solid when the device is fully charged.

How to Fill the Vaporesso Coss Hub and Device

To fill the Vaporesso Coss, you need to start by filling the reservoir. Remove the reservoir from the hub and look for the red silicone cover on the bottom. Open the cover and add e-liquid until the reservoir is full. Make sure that the area around the filling port is completely dry and place the reservoir back into the hub.

Next, you’ll use the hub to fill the Vaporesso Coss device. Remove the sticker from the bottom of the pod and place the pod inside the device. Slide the device into the hub and push the tab on the side of the hub down to lower the device into the hub.

Push the button on the side of the hub to start the filling process. You’ll hear a quiet sound while the hub injects e-liquid into the pod. The filling process takes about a minute. You can remove the device from the hub when the lights on the hub turn off.

When you fill the Vaporesso Coss, remember these three important points.

• Don’t fill the pod past the “Max” line. You’ll need to go through the filling process about 2-3 times to fill an empty pod.
• While the Vaporesso Coss is refilling, the hub and device need to remain still and upright.
• Wait about five minutes before vaping after filling a new pod for the first time.

How to Vape with the Vaporesso Coss

Learning how to fill the Vaporesso Coss is certainly a different experience compared to other vaping devices, but using the device is extremely simple – just puff to vape. Otherwise, the only thing that you need to do is keep an eye on the pod and use the hub to refill the pod when the e-liquid level is low. You’ll have to remember to keep the hub charged and refill the hub’s reservoir with vape juice periodically. The device, however, charges itself every time you insert it into the pod.

How to Fix Problems with the Vaporesso Coss

A device as unique as the Vaporesso Coss will come with a bit of a learning curve, and that’s not just the case when you use the device. The Coss is a fairly complicated vaping system, which means it can potentially have some unique problems that you wouldn’t encounter with other types of vapes. If your Vaporesso Coss isn’t working, you’ll find some troubleshooting tips here that’ll help you fix it.

Vaporesso Coss Not Filling

If your Vaporesso Coss hub is unable to fill the device when you press the button, the hub should stop the filling process, and the light should flash five times. When this happens, you should follow these three steps.

• Remove the reservoir from the hub. Make sure that the bottom of the reservoir and the receptacle at the top of the hub are both clean and dry.
• Make sure that the reservoir isn’t empty.
• Check your e-liquid. For best performance, you should use the Vaporesso Coss with an e-liquid containing no more than 50 percent vegetable glycerine. Anything with a higher VG/PG ratio may be too viscous to work reliably.

Vaporesso Coss Leaking

The Vaporesso Coss is a complicated vaping system with a lot of moving parts. If you find leaked e-liquid anywhere on the device or the hub, you should remove it right away and ensure that the problem doesn’t happen again in the future. Here’s what you should do.

• Make sure that the e-liquid in the pod is below the “Max” line before filling the pod.
• Don’t overfill the reservoir. After filling the reservoir, make sure that the silicone plug is fully closed.
• When you puff on the Coss device, don’t use more air pressure than what’s necessary to make the device turn on.

Vaporesso Coss Not Hitting

If your Vaporesso Coss doesn’t generate vapour when you puff on it, the solution is probably very simple. Follow these steps to troubleshoot the issue.

• If you’re using the pod that came with the device, make sure that you’ve removed the sticker from the bottom of the pod.
• Make sure that the Coss device is fully charged. If nothing happens when you insert the device into the hub, charge the hub.
• Remove the pod and check for a leak. If you find e-liquid under the pod, dry the pod and the Coss device thoroughly and try vaping again.
• If the Coss device still isn’t hitting, try installing a new pod.

Vaporesso Coss Not Charging

When you insert the Coss device into the hub, the hub should vibrate, and the indicator lights should begin pulsing. If the Coss doesn’t charge, follow these steps.

• Make sure that the hub is charged.
• Check for a leak inside the hub, where the connectors on the bottom of the device touch the hub. If you find e-liquid, remove it completely.
• Also confirm that the bottom of the Coss device is clean and dry.

Vaporesso Coss Hub Not Charging

When you connect the Vaporesso Coss hub to a power source, the hub should light up. If the lights don’t turn on, follow these steps.

• Remove the device and reservoir from the hub and check for a leak. If you find e-liquid, remove it completely.
• Try connecting the hub to a different power source such as your computer. Don’t try charging the Coss hub with a high-speed charger for a smartphone or tablet.
• Try charging the Coss hub with a different USB cable.
• Make sure that the hub’s charging port is clean, dry and free of debris.

Vaporesso Coss Review: Final Thoughts

We can guarantee that the members of the vaping community will have a wide range of opinions about the Vaporesso Coss. For some people, it’ll be a complete game changer that eliminates or at least mitigates some of the common annoyances of using most vaping devices.

Other people will almost certainly call it an overpriced novelty – undeniably fun but not worth the high price.

Where you fall on this spectrum will depend on how you feel about the Coss’s limitations, which are fairly significant.

• The hub is a very complex device with many moving parts. This is a first-generation device with completely new technology, so it’s difficult to guess how long the hub will last. Vaporesso’s factory warranty is only 90 days.
• If the hub stops working, you’ll have no way to charge or fill the device.
• The Coss is significantly more expensive than other pod systems and doesn’t offer the same level of vapour production. The higher cost will only be worth paying if the system addresses some of your pain points or if you’re a vaping enthusiast who wants to try something unique.
• The automatic filling process eliminates the mess of filling your own device, but it also takes much longer.
• Since the Coss doesn’t detect the level of e-liquid in the pod automatically, it’s possible to overfill the pod.
• The Coss device is extremely small, but the hub isn’t – and unless you’re not leaving the house for long, you’ll always want to carry the device in the hub. Combined, the device and hub are larger and heavier than most traditional pod systems that offer better battery life.
• The Coss feels more like a cigarette than other pod systems, but it can’t compare to the even smaller size and weight of a cigalike.

Pros

• It’s fun and extremely unique.
• It’s perhaps the first pod system that you can comfortably hold between two fingers, although it’s probably a bit too heavy for dangling from the mouth.
• You can potentially vape for days without charging the hub or adding e-liquid to the reservoir.

Cons

• It’s more expensive than devices that offer superior performance.
• The hub is a single point of failure with unknown durability.
• The device and hub have no mechanism to prevent overfilling.
• The automatic filling process is very slow compared to filling a pod manually.
• The novelty may wear off quickly.
