Cuboid 200 TC Mod Review

A complete makeover of Joyetech’s Flagship Mod

• Joyetech
• Cuboid 200W
• Triple 18650
• TC System
• Firmware Upgradeable Mod

I have to candid here, within a couple of days of reviewing the original Joyetech Cuboid, I put the mod in the stockroom and never picked it up again. The reason was it was just too damned heavy for me, and that Cubis tank with its top down coil head turned out to be a nuisance to refill. Lifting the entire atomizer contraption out of the tank itself, and then getting the eliquid into the tank without going past the maximum fill line, all without making a mess, was too much for me. Although I’ve had nightmares of spit-back and gurgling with most of Joyetech’s top-down coil heads, I don’t remember that being a real issue with the Cubis, but refilling issues were enough to not bother with it. Today, with the newly designed Joyetech Cuboid 200 TC all that has changed. The new Cuboid is still on the heavy side, but understandably so, which I’ll get to later.

Joyetech Cuboid 200 TC Mod Design Refresh

The Joyetech Cuboid 200 TC Mod has increased the wattage power over the original, from 150W to 200W. The new Cuboid has added the new preheat functionality with the latest Joyetech firmware, and put it all in refreshed and redesigned slim shape body. The Joyetech Cuboid 200 TC requires (3) 18650 high-amp batteries (sold separately), one more than last year’s dual cell Cuboid, which negates the lighter body and makes the Cuboid 200 TC about as heavy as the original dual cell Cuboid.

In addition to the much more pleasing body design, the Joyetech Cuboid 200 TC includes the newest Variable Temperature Control system (firmware V6.04) which has increased the accuracy for Nickel, Titanium, and Stainless Steel 316 temperatures while in TC Mode and a new customized TCR mode. It even features the custom logo ability that many of the WISMEC/eLeaf/Joyetech mods now enjoy.

The new Cuboid 200 TC features a bright, large 0.96″ OLED display screen we’ve seen in other Joyetech high-end devices like the eVic line. Unlike the original Cuboid the OLED display is now on top of the mod, but it works for me, and will probably work with you as well. Worth noting is how Joyetech created an opaque semi-circle extension coming off the .96” square display, stuck the adjustment “bar” between the actual display and the opaque extension in order to create a larger looking display that extends three fourths of the total area of the top of the mod. See the photo here for what I mean.

The Cuboid 200 TC Display

What’s seen on the screen is worth mentioning in this review. The OLED display shows you all three cells individually so you’ll know and recognize the performance of each cell. It’s an excellent way to determine which batteries are getting old, how well they hold their charge, and help you see if any battery could become unstable due to excessive discharging. Remember to marry three identical cells with an amp rate of at least 25a. We’ve purchased a case of Sony VTC6 cells and they are highly recommended here. The rest of the display, starting at the top of the screen and working down toward the semi-circle area, begins with the mode the mod is in, then the largest type showing the wattage or temperature, depending on the mode. Under the wattage/temperature line is a small line showing both the ohms of the coil and real time readout of the amperage. Under that is the puff counter, under the puff counter is the actual wattage while in TC mode, or the actual, real-time voltage output while in Variable Wattage mode.

Cuboid 200 TC Feature Highlights

Exchanging batteries is pretty straightforward; pull the battery cover out, replace the batteries, and push the cover back into place. There is a slight lift to the cover and it can feel quite snug, but when the cover is properly in place you’ll know it.

Other feature highlights include a stainless steel 510 thread with a wide border that goes nicely with larger sized tanks. The micro USB port is used for firmware updates. Although the USB port can charge the batteries, when it comes to charging three cells, it’s just not worth it. Charge your batteries with an external charger.

Like other Joyetech, eLeaf and WISMEC devices, the Cuboid 200 TC offers the same reverse polarity protection and dual circuit protection, making devices from these three companies some of the safest on the market. Over-charging, over-current, and over-discharging are now a thing of the past with mods from these brands.

The Pre-Heat Function

The Cuboid 200 TC sports the new preheat function found in the latest devices from WISMEC and eLeaf, as well as Joyetech, and it allows your device to start out at a high wattage output for just a second or two, in order to warm up the coils. When using RDA’s, RTA’s or even ceramic coil heads, this can improve the vape quite a bit by giving it a sudden jolt of power.

Real World Usage Report

The Joyetech Cuboid 200 TC uses an ultra-premium, glossy zinc alloy that not only gives the mod an extraordinarily nice look and feel, it also serves to make the Cuboid 200 TC a durable mod that will look brand new for a long, long time. I chose the grey one, though it is also offered in black and silver. After seeing the black one that Julia chose, I just may have to pick another Cuboid 200 TC up from MyVaporStore. At $47.95 for all these features and the premium finish, it’s a great value.

The battery compartment is shaped so that slipping in the three cells is fast and easy, there is no rubbing batteries together or squeezing them in. I liked that a lot. The battery cover caused me a couple of minutes of minor frustration, but as soon as I realized how the battery cover “catch” worked it instantly became a non-issue.

Because the OLED display takes up a lot of room on top of the Cuboid 200 TC, it’s a cinch to catch a glance at the setting, or to work with the setting using the adjustment bar directly under the display. What remains on top of the Cuboid is used for the 510-battery connector.

All in all, the new Cuboid 200 TC is a much better effort by Joyetech when compared with last year’s overweight cube device. This new Cuboid is no light-weight though, but with an extra 18650 cell and the premium zinc alloy finish, I think Joyetech did their best to make it a comfortable mod, and a little lighter. It does feel better in my hand as well, which is something I didn’t expect.

What sold me on the Cuboid 200 TC is the extraordinary number of features, the gorgeous look and feel, but the price pushed it over the edge. When I consider how much other similarly equipped devices can cost, the price/value of the Cuboid 200 TC is easily a winner.

Grade: A+

“Not for newbies, but an awesome box mod for vapers that want it all, and don’t want to pay a premium for it. Buyers will get more value from the Cuboid 200 TC than most anything else on the market right now.”
