The Spinfuel Review – Modefined Prism 250W Box Mod – Available at Element Vape

Change is good. For years, I’ve avoided three-battery mods. They always seemed unnecessarily bulky, awkward and even silly, considering I never saw much battery life improvement as the result of using them. Earlier this year, the Wismec RX Gen 3 started swaying my opinion, but didn’t truly convert me.

Well, I’ve finally seen the light. Because, of all the mods I’ve reviewed these past few weeks, only one never leaves my side – the Modefined Prism 250W mod. It might be large, but for the first time, I feel like the extra size and battery capacity is fully justified. Let’s see why…

I love the Prism’s packaging. Probably because I also love Pink Floyd. (“it’s the only music I’ve been playing since July” – ed) In a pretty obvious nod to the iconic “Dark Side of the Moon” rainbow graphic, the box is more appealing than most in the vape world, and invites buyers to explore a little further. (Copyright infringement, notwithstanding.)

Opening up the “gift box” (as Modefined amusingly terms it on the packaging) reveals the elongated, but hexagonal Prism mod, a USB cable, and not much else. But most users will be too busy salivating over the Prism’s streamlined design and rugged construction. In short, this mod looks about as durable as anything we’ve seen short of the old welded boxes of yesteryear.

My gunmetal/carbon fiber test model has enough contrast – mostly through the stainless steel buttons and carbon backing – to feel distinct, but it also has an air of maturity so uncommon on larger devices. While there’s no doubt this is a formidable, powerful mod, I feel as if Modefined also took into account that not all vapers want to have their vape mods draw unnecessary attention. Subtle, strong, and altogether beautiful.

Looking a little closer, the Prism is extremely well-machined, with seamless construction, powerful battery door magnets, and strong, screwed-in plates that just drip with durability. And, speaking of the battery door, my test model has a phenomenal textured grip that never digs into the palm, but has a reassuring grip – an important feature on such a large device.

Finally, the Prism’s large, 0.96-inch, monochrome OLED display is bright, though the slightly tinted screen made it a little difficult to read in direct sunlight. It’s not a deal breaker, but something worth noting for vapers who regularly adjust their mods.

As mentioned in the Prism preview, the onboard chipset and operating system isn’t exactly a name entity, like the popular DNA or VO boards. But Modefined did a hell of a job emulating the industry’s best, since this is a seamless, familiar experience that most vapers should adapt to quickly. While I wouldn’t call the Prism a “beginner device,” it certainly makes things easy enough for newcomers to learn.

Using the clear navigation, vapers will easily adjust wattage, temperature, coil type, bypass and more. All standard TC settings are included, but more-advanced users should note that the Prism mod does not have TCR settings, custom setting save slots, or any of the more granular customization they’ve come to enjoy on their devices.

The front-positioned buttons are firm, but do have a noticeable rattle when shaken. It’s not distracting, but is nonetheless a rare black mark for the Prism. That said, Modefined answered my pleas and included a center-positioned “action” button, eliminating the awkward and inaccurate method of using the fire key for desired inputs. All in all, the system works as intended; it’s not going to redefine how vape devices operate, but it gets the job done right, every time.

The Prism’s rock-solid 510 connection handled every tank and RDA in my collection with ease. There was no overhang, even with my 30mm Modfather tank, as the near-centered connection can accommodate all of today’s most popular atomizers. In turn, thanks to a springy but firm steel 510 pin, there were no gaps to be had.

One note – the low-positioned USB connection can be used for both firmware upgrades and onboard charging, but it’s not recommended. Though I never felt it was dangerous, per se, the Prism became VERY warm when charging three batteries in series. My suggestion? Only use this as an emergency option, and have extra batteries handy.

Power. Power is what the Modefined Prism is all about. But that’s not to say it isn’t graceful in delivering its three-battery, 250-watt assault. In the past few weeks, I’ve reviewed countless mods from all price points. And each of them had upsides and downfalls. Only the Prism delivered consistently without any hiccups, which is why it has rarely been out of arm’s reach since arriving at my office.

Starting out using the Uwell Valyrian sub-ohm tank, with a 0.15-ohm coil, I set the Prism to a conservative 65 watts and vaped. The resulting cloud could have been featured in an ‘80s Winger video, and might still be lingering in my attic. And this was well below the coil’s stated range of 120W.

What was impressive wasn’t that the Prism could hit 65 watts – this is a 250-watt device, after all. Instead, I was floored by how smooth it ramped up and maintained long drags. As I’ve mentioned in other reviews, I sometimes wonder if vapers have become accustomed to underpowered devices, which is why they choose to aim for higher wattage with each new mod they buy.

Here, 65 watts was more than enough for warm, flavorful vapor. It felt powerful. It felt controlled. And it felt ACCURATE. Of course, I wasn’t going to stop there, so I pushed the device to 90 watts, and continued to fog my office like a Seattle morning.

At 120 watts, the Prism remained cool to the touch, and continued to deliver pulse-free, butter-smooth draws. At 160, things were still comfortable, even if the coil was beginning to struggle. Switching coils solved this issue, and before long, my testing resumed.

At 200 watts – a level I NEVER reach in my everyday travels – I was amazed at how the Prism just kept going, with nary a slip or misfire to be had. Granted, the battery door began to warm a bit when vaping consistently here, but it was still never hot to the touch.

This being a test, I built a special low-resistance coil and pushed the Prism to 250 watts. I didn’t WANT to, but journalism is journalism, and it had to be done. Using a Kanthal coil on my trusty Goon 25mm RDA, I made peace with the almighty and fired off a succession of quick draws. And the Prism delivered again.

After 10 short draws at max wattage, I no longer wanted to vape this way, but the decision was made by user preference, NOT device limitations. Indeed, the Modefined Prism is a true 250-watt device, for those brave enough to venture that high. Battery life began to drop precipitously at this level, but that’s to be expected at such wattages.

I let the Prism cool off for a few minutes, then switched to an 0.2-ohm Ni200 coil for temp control testing. I was happy to report that the device never once stopped, or threw out a heat warning because of high ambient temps.

Instead, I simply navigated to the preset Ni200 mode, adjusted my settings, and continued vaping. Did the TC mode have the level of customization of a higher-end device? No. But I’m not sure it needed it. Carbon fiber aside, the Prism is a no-frills, pure performance device.

Finally, I should note that battery life on the Modefined Prism is outstanding. Even when vaping consistently north of 200 watts, batteries drained evenly and steadily, with the only sharp drops coming from my max wattage vaping.

At more conservative levels, the Prism should give users a full day of moderate vaping, when using three matched, charged 18650s. As always, be sure to use only matched, evenly charged batteries when using mods, kids.

The Modefined Prism is an absolute gem, especially at such a friendly price point. Though the cost screams “discount,” the feel, appearance and unwavering performance position the Prism as a true high-end vape mod. Only some minor button rattle, and questionable onboard charging lowered the score for this otherwise pristine device.

I may never once take the Prism past 200 watts. But I know I can without every worrying about failures or faulty performance. I highly recommend the Prism for any vaper looking for pure power, and performance to match.
