Joyetech Unimax 25 atomiser and mod kit

Joyetech Unimax 25

This week I am taking a look at the Joyetech Unimax 25 atomiser and mod kit.

Joyetech Unimax 25

The Joyetech Unimax 25 comes in a standard Joyetech white box with the device clearly pictured on the cover.

Nested inside of a foam insert in the top of the box we find our new Joyetech Unimax 25

Below that we find a load of documentation including a warranty card, safety card, users manuals for the atomiser and the battery mod, some black stickers and some spare vinyl stickers.

The vinyl stickers are to replace the installed one on the battery mod, or to change the colour of the mod.
My mod was black with spare brown stickers, and another that was blue with spare black stickers.
The stickers are a very very nice leather effect vinyl and are made by 3M with their 300LSE (an extremely good) adhesive.

Below the documentation is a small box with some spares in it. These spares include the USB cable for charging the battery mod, a spare coil (a 2nd is pre-installed), a spare glass tank and a complete set of spare 0-rings.

Here we can see the Joyetech Unimax 25, shown in both the black or blue variants.
There are also a brown or a red (looks more like pink to me) versions with the stainless steel tube and a full black version with a black powder coat on the stainless steel and black vinyl.

Looking at the tube first, we can see the ‘front’ has some nice accents between the stainless and vinyl.
It is etched with the Unimax model name and has just a single power button at the top end of the tube.

On the ‘back’ we have a similar look, with the Joyetech brand etched at the bottom and the USB port at the top.

The base has some descriptive text, what appears to be a serial number, the usual CE and recycling icons and a reasonably sized vent hole.

The device arrives with the atomiser installed, it unscrews to reveal a standard 510 threaded connection.
The 510 is stainless steel threaded and has a brass, spring loaded positive pin.

Now let’s take a look at the new atomiser design that comes with the Joyetech Unimax 25.

The drip tip is an oversized plastic drip tip, that fits around the outside of the socket via a slot and notch design.
A standard sized hole is part of the socket, that allow the insertion of any standard drip tip.

The atomiser is a top fill, top air flow design. It has a down-pipe to separate the incoming air from the outgoing vapour.
The air flow can be adjusted by turning the upper part of the top cap, whilst turning the complete top cap allows for it to be removed.
Once the top cap is removed it will reveal a pair of large filling slots where you can add liquid.

The main atomiser coil assembly can also be unscrewed from the base of the atomiser, to allow for coil replacement or easier cleaning.

The atomiser coil itself screws into the base to secure it, but once removed you can even replace the glass tank (or just remove it temporarily for cleaning).

The coil head is also screw fitted to the tank top.

Once removed from the tank top we can get a better look at the Joyetech Unimax 25 coil heads.
They have 3 large liquid ports in the middle of their bases, 3 large air ports around the edge of their top and a moderate hole for the vapour to ‘escape’ from after passing by the vertical coil design.
Both the pre-installed and spare coil are 0.5ohm kanthal coils that are supposed to be direct lung inhale design but some might find them a little on the restricted side of lung hitting.

Here are a few specs.

Size: 25.0mm*134.5mm
Battery capacity: 3000 mAh
E-liquid capacity: 5ml
Weight: 156g (with coil head)
Output mode: direct output and constant voltage output
Resistance range: 0.15-3.5ohm

The atomiser can use both BFL and BFXL series heads and with an adaptor (sold separately) they can even use the older BF series heads.

The device also has protection from over current, over charging and over discharging.

So, opinions…

The Joyetech Unimax 25 is a nice looking device, the leather look vinyl panels really make it look good.
Whilst I didn’t try to remove the vinyl stickers I did pick at a corner of one to see if it came away easily, which it did not. The stickers should last a long long time with their 3M waterproof and oil resistant adhesive.

The single button design with constant voltage opinion is a good idea, not ever vaper wants to fuss with a multitude of settings and just wants to vape.
In direct mode the device will last longer before recharges but the user will notice a subtle drop off in vapour production. In constant voltage mode the vapour will be the same at the end of a charge as it was at the start, but the charge will not last as long.
Switching between them is just a long press when the device is off until the button surround flashes.
The surround also flashes after each use to indicate the remaining charge, the more it flashes the less charge you have remaining.

The atomiser is also rather good, the top airflow is easy to adjust and the top filling makes for fuss and mess free tank fills.
I found that the drip tip became somewhat loose after examining it, if you intend to use the installed drip tip I suggest you never remove it.
The airflow of the atomiser is really good, where it restricts most is in the supplied 0.5ohm kanthal coils. It’s not a tight draw, just on the low end of lung inhaling.

It is nice that the kit includes not only a new glass tnak section but also a complete set of o-rings and a spare coil.

Where I did run into problems was with refills of the tank. I found that the coil heads are somewhat prone to over wicking. With this in mind users should use some caution with refills to avoid this.

That said, overall the Joyetech Unimax 25 is a great little device, qquick and simple to use.

There is no word on the Joyetech site as to the suggested retail price, but I have seen these online at just $33. Good bargain at that price.
