Introduction – The Maxo Zenith Mod by Ijoy

The iJoy Maxo Zenith Mod promises to be yet another innovative and seriously high powered device.

Coming from a vaping giant that’s been upping its game of late with a string of uniquely innovative and affordable devices that just leave absolutely no holes barred.

When I say innovative I’m not saying so lightly, iJoy have brought us the first dual 26650 mod, a result of their partnership with Limitless: the iJoy/Limitless Lux.

The iJoy/Limitless RDTA’s are a staple in the vaping community and let’s not even mention the magnificent iJoy RDTA Box.

More recently they brought us the first quad 18650 device and brother of the Maxo Zenith, the iJoy Maxo.

The innovation doesn’t end there.

In the iJoy Maxo Zenith we see the dawn of the ‘infinite’ adjust potentiometer!

The device is devoid of display or wattage adjustment controls, set to bring us a new understanding of our vape with a 2.7-6.2V dial that will see you vaping at anything up to, well…whatever 6.2 Volts of vaping power actually means: uh huh, around 300W of power!

Build Quality & Design

On sliding off the package sleeve and opening the simple white box, I was instantly pleased. The pictures I’d seen of this mod online had done it absolutely no justice.

We’d ordered the Silver Variety and the finish is beautiful, horizontal-brushed Zinc Alloy, which not only looks but also feels incredibly durable.

The ergonomic design, very very much akin to the Wismec RX200 shape, yet ever so slightly larger, has something of an old-school Sci-Fi edge to it which becomes a little bit more real when you pick it up and feel the 150g weight.

Below the massive top-firing button, which is so clicky you can dance to it, you’ll see the first set of battery vents in the shape of the iJoy logo.Maxo Zenith power button

With the slightest pull the battery cover comes off to reveal an impressive, solid looking battery chamber with gold-plated, spring-loaded connections for no less than 3 18650s.

Oh, bring the cover back to within a centimeter of those magnets and they’ll pull it back into place with a force that is no less than pleasing to the senses.

Adorning the other two side panels, those next to the battery cover, you’ll find the second set of massive battery vents, recessed and perforated panels that can only be described as ice-hockey stick shaped.

They add to the sci-fi appeal of the mod but hang on…it goes on.ijoy zenith power button and lights

Pop in those batteries or press the firing button 5 times and the Maxo Zenith comes alive with light-saber-bright green LEDs which blast out from within, shining through the vents and next to the firing button…to make you all warm and fuzzy inside.ijoy maxo zenith star wars mod

I’ve fitted the device with all manner of tanks, from RDTA’s and TFV8 Cloud Beasts to Mini Sub-Ohm tanks. Dare I say, you’ll be seriously hard pressed to find a tank that doesn’t fit flush on this device.

The surface area is ample yet the battery chamber is designed in such a way that this mod’s small enough for a mini vape tank.

It was, of course, made for no-holes-barred sub Ohm beasts like the iJoy V12 and the TFV12 Cloud Beast King from Smok and believe me, there can be no greater joy for a vape-master than owning a device that allows you to explore all the limits of your tanks and builds.

How Does The iJoy Maxo Zenith Perform?

So, many of you might find the prospect of a Potentiometer only device with no display and no wattage mentioned anywhere in the terribly vague and altogether useless manual and a little over 300W of raw power…somewhat, er, daunting.

Let me just say that, while I’ll admit that this is no beginners device, it won’t take you long to wrap your head around it: it is, in fact, far simpler to operate than the mods you’re used to.

Understanding the iJoy Maxo Zenith Potentiometer.

Okay, so this funky little lightning dial on the side might be slightly difficult to get a handle on with your big wigglers but trust me, it’s a good thing you can’t just touch it and boom because this thing is p..p..powerful!

Ohm’s law basics here, people. The max output current on this device is 50A and Wattage is determined by multiplying amperage by voltage so…

50A x a sort of mid range setting on your Potentiometer of 3.2V is gonna give you: 160W.

It’s not a lightweight’s device and it didn’t take me long to understand that. Unless you have a killer tank like the iJoy V12, take it easy on the dial there, son…or you will see some burned coils.

I must say, there’s something strangely cathartic about suddenly just being able to kick back and twist instead of clicking seven times then twice to the left then reading then clicking and so on.

Breath out, twist, inhale. Hell yeah!

It’s obviously recommended that you understand Ohms law but there’s also no reason why you can’t start with the potentiometer flat and slowly work your way up.

Just remember, especially on the higher settings, ramp is instant and before you know it…you can have your coils burned to a crisp.

How To Operate the Menu System

There is no menu system, as there is no screen…this is a five click power and then fire with the same button device and I’m not complaining.

How To Replace The batteries

  • Remove the super-magnetic battery cover.
  • Insert the two inner batteries negative up.
  • Insert the outer battery negative down.
  • Replace the cover.

Battery Life

Okay so, here I was pleasantly surprised once again by my new favorite.

When I removed the batteries to check their levels after about a 3 hour session of 0.15 Ohm coil vaping at 3.6V, I was delighted to find that they were still 80% full.

The absence of a display screen seriously extends battery life and I’m pretty sure this must be one of the most power efficient, high powered mods on the market.

A red LED will shine along with the green one to indicate time for a battery change.

Oh and, external charge only, vapers.

What I Liked

This system allows you to get on with enjoying yourself…you’re able to make all the necessary adjustments without even looking at the device.

I love working in different measurements, it’s a welcome break from wattage reading devices.

I love the power efficiency. I love the sci-fi fi look and fantastic light saber LED show.

Nothing compared for ease of use and the build quality is incredible. Especially the battery cover and chamber.

The instant ramp, incredible, tangible power is also a worthy addition to this section.

What I Dislike

There is nothing I don’t like about the Zenith Maxo, only, this is not for absent minded vapers who don’t know/or care what they’re doing.

You need to know the limits of your tank because you can burn the hell out of your coils in a heart beat on this thing. This is not a vape mod for beginners.

Final Review Verdict

I’m in love with the iJoy Maxo Zenith, I’ve been using it most of the time!

It’s the perfect device for testing out new tanks and builds as it can be smoothly adjusted in tiny increments using the voltage dial and it pretty much knows no limits with just over 300W of power.


If something were to happen to my beloved Maxo, I would buy it again in a heartbeat.

Greetings Vapers! I’m a 34 year old writer, editor and massive vaping enthusiast (since 2015) based in the beautiful Helderberg region in South Africa. My passion for vaping has steadily grown since I started vaping in earnest (as has my scorn for smoking). See, I tried vaping years before that but returned to cancer sticks after a bad experience (PG sensitivity). When I finally got back on the vaping train I decided to make it my business to educate beginners and vapers in general, so that they don’t jump to the conclusions that I did. I visualise a world without cigarettes…not just for health reasons: I’m tired of picking thousands of cigarette butts up off my lawn every morning, tossed over the wall by passers by. I can’t believe I used to be one of those people!


  1. Great Review and looking forward to trying this mod out. All specs and the over all look are very appealing, but I’m not a fan of these companies putting LEDs all over the mods, they aren’t after all kids toys. Also when I smoked I didn’t need a bunch of flashing lights saying look at me. There just needs to be a way to turn them off. But, I do like the mod and I am very interested in getting one. Thank you for the fantastic read.
