First Impression Out Of The Box:

This mod is packaged in a clear type of jewel case. Rightfully so because this mod looks like a little jewel sitting in the box. From the second you open up the clear top of the box, this mod just exudes quality. Take it out of the box and put it in your hand and you are greeted with a very ergonomic mod. It will feel great in your hand from the first moment.

What’s In The Box:

  • Callisto Mod
  • Instruction manual
  • Battery safety card

I was a little surprised that a USB cable was not included in the packaging. While most of us do have a ton of these cables, not including one concerns me because this could very well be somebody’s first mod. If it is your first purchase, you would appreciate having a USB cable in the Box. I am also a little disappointed in the manual. It is not well done at all and it just seems to be all over the place.

From Top To Bottom:

I’m kind of at a loss when it comes to describing the shape of this single 18650 mod. It kind of reminds me of a 1 battery Reuleaux. I only say that because I can’t find the words to describe what it really looks like. The beautiful thing about the Callisto is no matter which way you hold it, it feels great in your hand. By that, I mean whether you thumb fire it or finger fire it, it just feels right. It is an absolutely fantastic shape and probably the most ergonomic single battery mod I own.

The 510 pin is done very well and it sits flush on the top of the mod. The stainless steel threading is buttery smooth and there are three air slots that I would guess are for people who run older style tanks. The pin itself is very firm and has a decent throw to it. The 510 pin looks to be gold plated.

This mod has a bunch of curves to it but it does have a short flat end as well. On that short flat end, you have the fire button, screen plus & minus buttons, and the update charge port.

The fire button is the same color as the rest of the mod. It seems to be stainless steel and it is circular and recessed. It has a short throw to it with a nice clicky feel.

The screen has a blue font to it. It is a simple yet elegant screen that provides all of the information that is pertinent to a vaper. On the bottom of the screen, there is a battery meter bar that runs along the whole bottom of the screen. The rest of the information shown would be the wattage, temperature, mode, ohms, and volts. The screen is very well done and can be seen in almost every lighting condition.

On the bottom of the mod, there is no venting. There is a place for you to put your thumb in order to remove the battery door. The battery door is not plastic and is made out of some type of metal with a really nice industrial looking black paint. The battery door has a grippy feel to it and there are cut out running along the battery door from side to side. On the inside of the battery door, there are four strong magnets on the edges as well as two type of rubber inserts in the middle of the inside. I am assuming these inserts protect against battery rattle. The battery door is nice and solid with an extremely slight wiggle. The Wiggle in it is nowhere near bothersome and it does not become an issue when using the mod.

The battery sled has battery orientation markings clearly identified. The battery goes in negative side up. The negative side battery contact is spring loaded and gold plated. It is nice and firm but not too firm that you’ll rip your apps. The bottom battery contact is for the positive side and it has a button style gold-plated contact. All in all, the sled is very clean and well done.

On the curvy sides of the mod, there is some Callisto branding but it looks to be like stainless steel on stainless steel. So it has the effect of being very subtle. On the side opposite of the branding, there is some COV branding with the same type of sticker or edging. The stainless steel on the Mod is absolutely beautiful and it does wear very well.

The plus minus buttons are made out of the same material as the fire button. They look exactly like the fire button, just smaller. They have a nice clicky tactile feel to them but I do wish they were a little bigger. Right below the plus minus buttons, we have the charge port. It is a horizontally mounted port. While most of the times I highly recommend that you charge your batteries externally on a single battery mod, I don’t mind charging internally. It’s a nice feature to have on a mod like this for when you are on the go. The Callisto is not firmware upgradeable.

The Look, Feel, and General Aesthetics Of The Mod:

Like I said earlier in this review, this is probably the most comfortable single 18650 mod I own. I think it looks great and feels great. The design on this is so ergonomic which makes this mod just a pleasure to hold. It is also extremely well-built and has a nice quality, heavy feel to it. Even when the battery is not in the mod, it still feels like a high-quality piece. This is definitely the best looking single battery mod I have in my vape arsenal. The Callisto is a very pocketable mod that borderlines on a stealthy mod.

The Board:

This is Council Of Vapor’s proprietary board. It has a full temperature control suite. It will do Ni, Ti, and SS. There is no TCR function. The COV board does a very respectable job in TC. I do wish it did have a TCR function. I understand COV not including a TCR function because after all, it is a one battery mod that maxes out at 80 watts. So you probably won’t be running a lot of exotic dual coil builds on it. However, it would have been nice. I like the way the mod vapes in power mode and so far I tested it out in Ni and SS mode with very good results. It’s no DNA or Yihi board but it does do a very good job in temperature control mode. I do wish there was more than one option under the SS menu but so far, every SS coil I’ve used on it has vaped pretty well. The board in this mod is one of those boards that do not allow you to control the wattage while in TC mode. Normally, I don’t like chipsets that don’t allow you to adjust the wattage in TC mode but this board does a very good job at coming in at the right wattage. I do wish I was able to dial in my own wattage though. That is really my only complaint when it comes to the TC on this mod.

The Menu System:

  • 5 clicks to turn the mod on
  • While the mod is on 5 clicks get you into the menu system once in the menu system One Click of the fire button will scroll you through the options
  • Use the plus minus buttons to select the desired option
  • 3 preheat functions standard, powerful, and soft
  • 3 clicks to lock and unlock the mod

All in all a pretty simple menu system, nothing too fancy or overly complicated.

How Does It Vape:

While in general, I am really not into single battery mods, I do have certain setups that I do like to vape on mods like this. I like using the Callisto for my MTL setups. I get really good battery life and a really good vape. It looks good with all my tanks up to about 24mm. After that, you do start to get some overhang. Power mode seems to be very accurate. TC mode is accurate as well, I just wish there were some more options. Don’t get me wrong though, this mod does vape very well in TC mode. I like what Council Of Vapor has done with this chipset and as far as I’m concerned, it has a lot of possibilities. I would love to see this chipset in a dual 18650 mod. I think it would do well in that type of mod.


If you are looking for a well-built high-quality single 18650 mod, the Callisto is going to be very tough to beat. This is one of the nicest single battery mods I have ever owned. The build quality is top notch and the ergonomics are just phenomenal. You would have a hard time finding a better mod in this subcategory. It really is that good.

This is the type of mod that is great for a new vapor that is moving up from a small internal battery mod or some type of pen device. The Callisto does everything you ask of it with no complaints. It will work with the most popular TC wires and it is a great performer in power mode as well. It will do all that and look great while doing it. So if you’re the type that’s looking for a small quality mod, you will definitely want to give the COV Callisto a very serious look. This mod is DeucesJack approved.
