Well, if there’s a word to describe iJoy right now it must be “prolific”. As well as delivering the Limitless tanks and devices their own product line is rapidly growing too, their latest arrival on my doormat being the iJoy Maxo.
Stepping up their “power game” the iJoy Maxo hits at up to 315W (all the way down to 0.06 Ohm) and is billed as being usable with either 4 or 2 cells (in a lower power mode). So definitely one of the highest powered vape mods we have seen to date.
It’s available in red, blue, black yellow and (if you can find it) a limited edition marbled blue finish.
The mod is a solid, business-like matte black with gloss black and silver printing. On the front, the iJoy logo and product name, the sides and ends showing the same.
On the rear, we have an authenticity scratch panel, logos and contact details.
Inside The Box
Removing the lid, we find:
- The Maxo (in my case red) laid in a black flocked foam tray.
- Micro USB cable
- Warranty card
- User manual
- Selection of side grips in different finishes
Design and Build Quality
The Maxo is, unsurprisingly, an imposing mod given it holds four 18650 cells. It stands 89mm tall, 64mm across and 41mm deep, with an unusual rounded heptagonal (7 sided) shape.
The body of the Maxo is constructed from powder coated alloy, secured with stainless steel Torx bolts.
On top, we find a stainless steel 510 connector with sprung centre post and air slots. The top plate carries the Maxo title and logo.
The sides are smooth, with rounded corners. On either side, we have vent holes and recesses to fit the self-adhesive grips, with one also housing the Micro USB connector.
On the front the fire & up/down buttons sit slightly proud of the black OLED panel.
On the base, we see the iJoy logo, battery polarity indications, regulatory marks and a slot to aid in opening the battery cover.
Sliding the battery cover open reveals the battery slots, well labelled both inside the lid and on the body. The inner terminals are sprung.
How Does The iJoy Maxo Perform?
That imposing appearance is incredibly deceptive. The shaping and rounding make the iJoy Maxo quite comfortable to hold and use, whether finger or thumb firing.
Even fully loaded with four 18650s the device doesn’t really feel that heavy. The grip panels are a nice touch and do alter the appearance/feel of the Maxo quite nicely.
The battery compartment holds the cells snugly, with no rattle even if only two cells are used. 
The cover can be a little tricky to snap back into place but gets there with practice. The 510 connector springing works well and the threads are nicely smooth.
The current version is v1.2 and it makes a massive improvement to the battery consumption of the Maxo as well as adding TCR mode which was missing from the original version. Head on over to their website to download latest firmware.
Maxo Functionality
Five clicks turn on the device, giving us a splash screen before taking us to power mode.
The OLED display is clear and bright, with resistance, voltage, puff counter, power and battery charge levels shown.
- When the fire button is pressed the voltage display changes to a fire time counter.
- The up/down buttons scroll smoothly through the power range, steadily accelerating you up to 315W.
- Three clicks then take you to the options menu, with options for power, temperature control (submenu), screen reverse, firing profile (submenu), TCR(submenu) and puff count reset.
Temperature control mode supports Ni200, Ti, SS316 and two user defined TCR values allowing a choice of other wire types.
When using temperature control you’ll need to set the base resistance by holding down the up/down buttons until you see the resistance displayed.
The firing profile allows the user to adjust how power ramps/tails when fired to suit their taste, with a user defined profile available.
This is like the one seen on the iJoy Limitless Lux and does make a difference with lighter/heavier coil builds.
The temperature control modes worked consistently well and TCR values seemed to translate quite accurately from the wire ratings.
Updating the firmware via the Micro USB port is quirky, you need to install the software, remove the cells, hold down the fire button and then (and only then) connect the USB cable.
That said once you’ve got past that step it’s rapid. A real shame however that iJoy didn’t include on board charging, which although sometimes slow is appearing on devices like the Wismec RX300.
Final Review Verdict
I really like the Maxo, it’s uncomplicated in the way it allows you to use two or four cells without needing to change panels etc.
The menus are clear and quick to access with good temperature control. The build quality is good except possibly for the paint.
It’s a little thin/soft and in places has scraped away with use. That said, it’s nothing a good wrap or silicone skin wouldn’t fix.
It’s a little disappointing that the USB connector only does firmware updates, but it’s just as well it’s there.
The initial firmware saw the device draining four cells almost as quickly as two in the Cuboid, with the same tank and same coils. Version 1.2 has fixed this and adds the very useful TCR mode.
iJoy have a great mod here, the Maxo should do well. However, they need to be mindful of pre-release testing and quality control.
Pros:
- Heavy hitter at 315W
- Option of using two or four cells
- Comfortable feel
- Consistent TCR
Cons:
- No on-board charging
- Paint finish a little thin
