Honest review time: The Aspire Mulus AIO

Aspire recently released a new all in one pod system that appears to follow a popular design trend. The original concept can be credited to an American company named Billet Box with their popular though often unattainable namesake devices that for a long time were quite coveted by the vape community. Price and availability often put them out of the reach of most average vapers so other companies started to mimic the design producing similarly styled devices that were much more affordable, feature rich and readily available. Aspires latest is called the Aspire Mulus and after spending a few weeks with it this is what I think of it.

Packaging and contents:

The kit comes packed in a clean white cardboard box with an image of the kit on the front and a listing of the contents as well as bunch on information on the back. Inside the kit you get the Mulus mod, a pre-installed 4.2ml pod/tank, a USB Type-C cable for charging, a user manual, a warranty card and three spare coils with one already installed. The kit also includes a Nautilus coil adapter which also come pre-installed with a 0.7ohm Nautilus 2S Mesh Coil. The other coils included in the kit are a Tigon 1.2ohm coil, a Tigon 0.4ohm coil and a Nautilus 1.8ohm BVC coil. Though the kit itself is pretty void of any extras it’s not very often you get this many coils packed in to a single kit.

The mod:

The mod is considered an AIO(all in one) and essentially looks like a box. It’s mostly made of lightweight aluminum with one of the panels being finished with a three colour resin but it’s also available in a non-resin finish. I wouldn’t have minded if both panels had the resin finish but hopefully they are available separately later on. It also comes with a matching resin 510 drip tip meaning you can actually replace it yourself unlike so many other pod systems out there with their proprietary tips. It stands roughly 97.4mm tall, is 50mm wide and 24mm thick. It’s just a tiny bit thicker than an actual Billet Box but for some reason I really notice the extra few millimeters. It’s got one rounded corner and all of the edges have been nicely rounded with Aspire calling it an ergonomic design. Not sure I fully agree that it’s ergonomic but it is lightweight and comfortable enough to hold in the hand.

On the working face of the device there’s just a single round metal button located in the top left corner. It’s primarily a thumb fire device but you could sort of wrap your hands around it and use your index though for me it was kind of awkward. On the opposite side there are three slits cut in to the removable panel, two to let you see your liquid level and another to let you read the display screen. The panel is held in place by a series of magnets and is held very firm with pretty much no wiggle on the one that I received. A small notch at the bottom helps in removing it. On the side furthest away from the button is the USB Type-C port for charging the device which it does at a rate of 5V/2A so charging is pretty quick depending on the capacity of your battery.

Popping off the back panel we can see the inner workings of the device. In the top left is the 4.2ml pod, on the right is the spot for the 18650 battery and in the lower left is the display screen and +/- buttons. The pod in the top left is held in place with a spring loaded connection and doesn’t actually need to be removed to refill it. There’s a silicone plug that’s accessible without removing the pod which makes top ups really quick and convenient. Removing and replacing the pod is just as quick and with that spring loaded system you just push down a tiny bit and pop it out. The screen is fairly small but is easy to read and the device only really has three basic modes which include Voltage, Watts and Bypass with wattage mode having a max output of 80W. The way the buttons work is a bit different with five clicks locking the device, three clicks putting it in stealth mode, fire/+ locks the buttons and pressing both adjustment buttons gets you in to selection mode. It’s really easy to navigate and with the limited options it’s a very simple device to use.

The Coils:

Possibly one of the most versatile aspects of the Aspire Mulus is the fact that it can use two different types of coils thanks to a handy Nautilus coil adapter. The kit actually includes four different coils for you to chose from, two being Nautilus coils and the other two Tigon coils. The four coils provide a really good range of mouth to lung all the way up to direct lung so you can pretty much vape on this thing how ever you’d like. The Nautilus coil adapter also has adjustable airflow thanks to a spinning base that you can open or close to your liking.

The four coils it comes with are a Nautilus 2S 0.7om Mesh coil rated from 20-25W, a Nautilus BVC Coil 1.8ohm rated from 4.2-5V, a Tigon 0.4ohm rated from 23-28W and a Tigon 1.2ohm coil rated from 10-12W. Basically you get two mouth to lung coils and two direct lung coils with one of each being Nautilus and the other Tigon. All four have fairly low power requirements and work great paired with the Mulus. I don’t really want to turn this in to a four-way coil comparison as I’ve technically reviewed most of these coils individually with other tanks and devices but I will say that whether you are using the Nautilus or Tigon coils you can pretty much expect a good experience. The Nautilus coils are well known for their flavour and the Tigon coils which are plug and play are also some top performing coils from my experiences with them. What I really like about them including four different coils is you can try out the various draw styles but also get a feel for what the different Aspire coils can deliver. Now if they could only include an RBA in the kit…


Now I will admit that the Mulus doesn’t feel quite as premium as say the original Billet Box but with all of the easy to use features and functions included I’ve got to say it results in a device that is much easier to use and maintain and is all around just a pleasure to operate. It’s also much more affordable but still has a premium quality feel to it. I think this kit will be perfect for anyone who’s ever coveted a Billet Box but were on the fence about spending the money. It’ll work well for both mouth to lung and direct lung vapers and with all of the coil options available to it pretty much anyone could fine tune it to their liking. Great job on this one Aspire!
