Fumot ECO 2in1 50K Review: Flavor Switching Done Right

Getting Started

Most disposables require you to remove a few stickers and maybe even a rubber stopper from the mouthpiece before you can use them. This device is a bit different, but still easy enough to get started with.

When you first take the device out of the wrapper, you’ll see two plastic sticks near the mouthpiece. These are stoppers that, as far as I understand, keep the e-juice fresh and prevent leaks during transport.

All you have to do is pull the two plastic sticks out of the e-juice tanks and rotate the mouthpiece to sit flush with the top of the device. That’s it.

Design & Build Quality

Fumot clearly went in their own direction with the design of the ECO 2in1 50K. While it has a rectangular, boxy shape typical of disposables, the rest of the design is rather unique.

Front and center are the two transparent e-juice tanks, each of which holds 12ml of ejuice. These tanks have a diamond pattern that gives them a sort of ‘jewel’ look, which is neat. Although the tanks are tinted to match the device, they aren’t cloudy, so you can see into them at a glance.

To make viewing the e-juice level easier, there’s also RGB lighting that illuminates the tanks whenever you take a draw.

The mouthpiece is made of hard plastic but comfortable enough to use. It’s this mouthpiece, though, that is the star of the show. To switch flavors, you pull up on the mouthpiece and rotate it 180°, and that’s all there is to it. The process requires two hands, but it’s otherwise easy and takes little time or effort to switch between flavors.  Each side of the device has the flavor printed on it, and whichever side the mouthpiece is sitting on is the flavor you’ve selected.

A plastic shell wraps the device from the top and bottom. The top is silver, while the bottom is a gradient that matches the flavors in the device.

Size-wise, the ECO 2in1 50K is a bit tall, but it’s otherwise a typical size and weight for a high-puff count disposable in 2026. At 103mm tall, 52.8mm wide, and 25mm deep, you’ll remember that it’s in your pocket. It also weighs 110g, so carrying around more than one at a time is a burden. But since each device has two flavors, just one device served me well during the day, as even when I was bored of one flavor, I could just switch to another, all with the same device.

While this device has no pictures of ‘Bored Apes’ (unlike the Digital Box 12000 and other Fumot devices), Fumot couldn’t leave primates out entirely. Each device has a cartoon image of either a gorilla or a monkey, some wearing sunglasses, one in baseball attire, and even a gorilla as a DJ. As I’ve learned, monkeys and gorillas on devices are kind of Fumot’s thing, and although I don’t understand why, the graphics are at least well done.

The display on the device is small, but it gets the job done. Battery percentage is clearly and brightly displayed alongside a Fumot logo. It’s simple, but since the e-juice level is clearly visible and can be physically checked, there isn’t much more information to want.

As a whole, the 2in1 50K is built well, but the beauty will be subjective. The all-plastic construction also makes it feel a bit cheap, despite the good build quality, which is something to note. 

Features

While the name is a bit complicated, the device itself is not. The main feature of the ECO 2in1 50K, which I touched on in the Design & Build Quality section, is the ability to switch between two flavors with a single device. The way that Fumot has accomplished this is really simple, but it works. Just pull up on the mouthpiece, rotate it 180°, and you’ve switched to another flavor.

Aside from this flavor-switching feature, there’s really not a lot else going on with the 2in1 50K. There’s no adjustable airflow, which I would have liked to have, nor is there adjustable wattage. The draw is a medium-to-tight mouth-to-lung, which should suit most disposable vapers, but a little adjustability would have been nice.

Each device houses two 0.9Ω mesh coils; one in each e-juice tank.  Fumot says a single device can provide up to 50K puffs from the 24ml (12ml+12ml) of ejuice, but keep in mind this is 25K puffs per flavor. If you don’t like a flavor as much as the other, you might find yourself going through one tank faster than the other.

I mentioned the RGB tank lighting earlier, and while it’s helpful to check your e-juice level in low-light situations, it’s very bright. There’s also no way to turn it off, which makes it a bit obnoxious to use around people, as it’s like you’re vaping on a portable party. It’s not the end of the world, but people will notice you vaping.

Flavors

Fumot’s devices always offer a huge assortment of flavors, so it’s no surprise that the 2in1 50K offers 19 flavor combinations for a total of 38 different flavors. Looking at the flavor selection, it’s a good variety, with fruit flavors, some ice and mint options, and even some candy flavors.  

For this review, I’ve been using four ECO 2in1 50K devices: Juicy Peach & Sour Apple, Banana Ice & Black Dragon Ice, Grape Ice & Black Ice, Watermelon Ice & Cool Mint. That’s eight flavors in total from four devices, which is pretty neat!

I’m going to describe how these flavors taste to me and what I think of them. However, keep in mind that just because I like a flavor does not mean that you will like it. Similarly, if I don’t like a flavor, this does not mean that you will not like it. This is solely my subjective opinion.

Juicy Peach & Sour Apple

This flavor combination is really great because you can switch from sweet and juicy with the peach, to tart and less sweet with the sour apple. Both flavors are great, and I used them pretty evenly. The peach tastes like fuzzy peach candy, while the sour apple tastes a bit like a Jolly Rancher candy.

Banana Ice & Black Dragon Ice

Here we get another candied theme, with the banana tasting like a banana marshmallow candy along with the slightest bit of cooling. The Black Dragon Ice flavor is honestly a bit weird, with a kind of perfumey and milkshake/ice cream taste that I’m not too fond of.

Grape Ice & Black Ice

These are another two flavors that I think go really well with each other. Grape Ice is a wonderful candied grape with cooling. I expected Black Ice to be a pure mentholated blast, but it actually tastes like blue razz. I’m not sure if the flavors got mixed up or what, but having a blue razz and a grape ice flavor in one device is fine with me. The blue razz is even sweeter than the grape, and all around has a good flavor profile.

Watermelon Ice & Cool Mint

Like most of the other fruit flavors that I tried, Watermelon Ice has a nice candied taste but it isn’t overdone or too sweet. Alongside it in the same device is Cool Mint, which is very slightly sweet but mostly an icy draw with a typical mint flavor. I would get a couple of draws with the sweet watermelon ice, then refresh my palate with the mint, which was very enjoyable.

How long do they last?

The ECO 2in1 50K comes with a lot of e-juice (24ml), and a decently sized battery for a disposable too at 1100mAh. As such, both the amount of vaping that you get per charge and the amount of vaping that you can get out of a single device are both pretty good.

I got 2-3 days of vaping from a charge, and that’s with moderate to heavy use. If you don’t vape very often during the day, you can easily stretch this out to 4-5 days of use, whereas if you’re a heavy vaper, expect closer to the 2 day mark.

Thanks to the transparent e-juice tanks it’s easy to see how much e-juice is used per charge as well. I tried to use each flavor evenly so that the tanks drained at the same rate, and each charge used about ⅕ of the e-juice (around  ~5ml of e-juice). Expect to get about 5 full charges of use before the e-juice is completely finished, which is 4 charges.

Charging speed is an area that could use improvement. I timed a few charges, and they all took about 1 hour and 35 minutes, which is very slow. For a device with so many innovations, I would expect it to have fast charging, not snail charging. The silver lining is that it can be used while it charges, but that doesn’t change the fact that the charging speed is terribly slow.

How do they vape?

You might think that this device would vape differently because of the two different e-juice tanks; like a jack of all trades master of none situation. But in my experience, the ECO 2in1 50K delivers an experience that is just like any other disposable; there’s really no significant drawback to the vaping experience because of the flavor switching tech.

Using one flavor and switching to the other on the same device is just like using a single-flavor disposable and then switching to another device for a different flavor. The only problem that I had was that the mouthpiece wouldn’t fully seat sometimes, leading to a noticeable airier draw. This was easily fixed by pushing down on the mouthpiece, though, so it’s not an issue that would prevent me from using these disposables completely.

Adjustable airflow would be nice to have some more control, but the draw is pretty good as it is. It’s a medium-tight mouth to lung, which is about how I like to vape. The option to make it a tad bit tighter would be welcome, but I can enjoy the draw that it offers and most MTL vapers likely will too.

I’ve nearly completely used one of my devices (Juicy Peach & Sour Apple) and I didn’t have any sort of change in flavor or degradation in performance. The flavor has stayed solid the whole time, and I haven’t had any leaking, burning, or spitback either.

Since each flavor is only 12ml of e-juice and has its own coil, it makes sense that the coil wouldn’t burn out, compared to larger devices that use a single coil for 20ml+ of e-liquid. Either way, good performance from this device right up until it’s finished.

Verdict

Compared to the last Fumot device that we reviewed, the Fumot ECO 2in1 50K is leaps and bounds ahead. When you compare it to other disposables on the market, it can certainly hold its own. I can see people choosing it for the easy flavor switching to keep things interesting through the day, or for the consistent performance that doesn’t change over time.

The flavor switching is easy, but more than that, the flavor combinations make sense. The dual flavors mirror each other in some way or the other, such as the coolness of mint and the sweetness of the watermelon, or the sweetness of the peach and the tartness of the sour apple. This makes the experience of using a single device feel much more like you have two completely different ones in your hand, which is really awesome.

There are, of course, some things that could be improved, such as the option to turn off the bright RGB lighting and faster charging speed. An independent airflow slider would also be a nice addition. I’m not a big fan of the all-plastic construction either, as it looks and feels like plastic, but it’s something I can live with.

As a whole, the ECO 2in1 50K is a really interesting device, and although it has its faults, the flavor switching, excellent performance, and consistent vape mean that you shouldn’t count it out. If you like the idea of having a long-lasting disposable with two flavors in a single device, I would definitely give it a try.
