The latest eVic from Joyetech is the eVic Primo, a powerful 200W dual-18650 mod with all the latest and modern features developed by Joyetech. How successful this eVic model will be is something only time can tell, and with the 2017 Chinese Holiday just ending, the eVic Primo will be showing up on vendor shelves any minute. We received our shipment almost a month ago, and they have seen heavy usage since then. This review is based on my own personal experience with it, as well as feedback from Tom, Julia and Kiera.

It could be said that the eVic is Joyetech’s ‘flagship’ box mod, and through its many iterations has taken various forms, including built-in LiPo battery models and single and dual 18650 models. This eVic Primo might do better in the marketplace than the last model, the eVic VTC Dual we reviewed last September, or it might not. One of the biggest selling points of the eVic VTC Dual was its versatility. The battery pack is removable, and the user could choose to operate the eVic with a single 18650, which in essence means that it became the eVic VTC Mini, or with two 18650’s using the larger battery pack. This time around the eVic Primo is strictly a dual 18650 mod.

eVic Primo Aesthetics

While the last eVic model was decidedly boxy, the eVic Primo is wedge-shaped, narrower at the front, getting wider going back. This wedge serves more than one function, from aiding the comfort level of holding one in the palm of the hand, to providing a wider than normal (25.5mm in diameter than the usual 22mm) top area for 25mm tanks

The eVic Primo comes with an extra ‘replaceable sticker’, which is a decently thick piece of material the user can use to swap out the accent color. My model is a black on black eVic Primo, and inside the box there was a brown ‘patch-like’ material so if I was inclined to remove the black one and replace it with the brown, I could… I wouldn’t, but I could. I mean, brown on black? No thanks.

eVic Primo Tech

The maximum wattage output of the eVic Primo has increased to 200W from 150W of the last eVic model. It supports 50-Amps of output for no-lag firing, and it can recharge at  1.5-Amps. Additionally, the latest bit of innovation from the Joyetech/eLeaf/WISMEC umbrella, the eVic Primo features the Powerbank technology.

Powerbank – Whenever a user of the eVic Primo needs some quick power for a smartphone, tablet, or some other compatible electronics, the user can siphon off power from the eVic Primo using a Joyetech dongle called the Avatar Reverse Charging adapter. This adapter screws into the mod’s 510-connector and features a USB port on the other end. It is a clever feature, and one some users may benefit from, but having it as an optional purchase will hinder the adoption of this tech.

At the end of this review is our list of features and specifications for the eVic Primo. You might want to take a closer look before making any buying decision. We don’t have firm pricing yet, but we doubt the Starter Kit version, which includes the Joyetech UNIMAX 25 Sub-Ohm tank, won’t be much more than $65.

UNIMAX 25

The Joyetech UNIMAX 25 is a 25mm Sub-Ohm tank and is Joyetech’s best sub-ohm tank in a long time. For years the Joyetech Delta 2 held a special place in my vape collection, and until the UNIMAX 25 I believed the Delta 2 was the pinnacle of Joyetech’s reach. Turns out Joyetech can still make a good tank.

I’m sure that part of my positive feelings for the UNIMAX 25 is the use of Kanthal A1 heating elements in by the BFL Kth-o.5ohm coil head and the BFXL Kth-o.5ohm coil head. In addition, both coil heads have a short wattage range, 20W-40W and 30W-50W. This allows the UNIMAX 25 to create excellent flavor and large clouds of vapor without a lot of wattage. Users will go through less eliquid, and extend the length of vape time with charged batteries.

The UNIMAX 25 has an easy to use  top fill method, while its airflow slot is also at the top of the tank. Joyetech calls this their TFTA system for top fill top airflow. And, as much as I’ve complained these past couple of years with Joyetech’s top-down coil heads (coil heads that screw into the top part of the tank, not the base), as huge spitters, I am thrilled to be able to say that the UNIMAX 25 does not spit, or gurgle… and this is after almost a month of use. Coil heads last about a week with High-VG, sweet eliquids, about the same as SMOK TFV8 coil heads.

The UNIMAX 25 is both a Direct Lung and Mouth to Lung tank. To use it as a mouth to lung you’ll need to close the airflow to leave a very small opening. For Direct Lung, the widest opening allows a huge amount of air to mix with the coils and ejuice.

Lastly, the wide-bore Delrin drip tip is different than most. The UNIMAX 25 tank’s top cap protrudes upward and the drip tip is more like a built-up ‘cap’ over this protrusion. To attach the Drip Tip, the user slips the cap over the protrusion and gives it a slight turn to keep it from coming off. It would have been nice to have had the cap ‘snap’ into place, but so far the cap has only come off a couple of times, without issue.

UNIMAX 25 Usage Report

When I was reviewing the UNIMAX 25 as a part of the tube-mod sub-ohm tank starter kit it was apparent that the UNIMAX 25 Battery was underpowered for the job, unless the user turned the airflow down to a strict Mouth to Lung size. While the battery portion has two modes, direct output and constant voltage, neither was enough to get the optimal vape from the sub-ohm tank. I was pleased to see this tank become a part of the eVic Primo Starter Kit.

After an hour or so of breaking in the 30-50W coil head I jumped the wattage to the supposed maximum of 50 watts. Flavor was every bit as good as the SMOK TFV8 line, and vapor was about 90% as good as the Cloud Beast with the quad-core coils, and considerably cooler.

With the airflow port wide open the UNIMAX 25 told me there was more to be had. I then took the Vaporshark Hedron to 55W with very similar, or marginally better, results. At 60W the tank truly shined; massively thick clouds of vapor and rich, sweet flavor (using Ethos Strawberry Crispy Treats).

While I will probably continue to use the SMOK TFV8 or the new TFV12 more often than not, I’ll keep the UNIMAX 25 in play and most certainly keep one on an eVic Primo.

eVic Primo Feature Highlights

Dual circuit protection

The eVic Primo uses two sets of battery protection circuit systems, providing true battery protection against over-charging, over-current and over-discharging. This dual circuit protection is now used in all eLeaf, WISMEC and Joyetech devices.

The eVic Primo is equipped with a solid 510 spring loaded connector, allowing for secure connections for any Tanks or RDA’s up to 25mm.

The eVic Primo is Firmware Upgradeable with both Mac and PC computers. The version that came preinstalled with our eVic Primo’s was Version 4.05, which includes the real-time clock, a preheat function, the custom logo feature, and the reverse charging (with adapter).

The eVic Primo equalizing charge system supports a quick charge capability with a maximum charging current of up to 1.5A.

Final Word

If you’re a fan of the eVic line you’ll find the eVic Primo a nice bump in wattage, features, and aesthetics. If you’re happy with your current eVic, then pick up the UNIMAX 25 or UNIMAX 22 Sub-Ohm tank to give your older eVic a nice shot in the arm. If you’re looking to upgrade, or add another mod to your collection, the eVic Primo is a worthy mod. The eVic Primo Starter Kit is the best buy, the UNIMAX 25 tank is, I like to think, a worthy victory for Joyetech.
