Let’s start with the iJoy Diamond’s color options because there are a lot of colors to choose from. Whatever color you choose will match the Captain X3S tank’s color and the kit is available in matte white, matte black, mirror blue, matte pink, champagne gold, mirror purple, matte red, mirror rainbow, mirror gun metal, matte green, mirror silver and mirror gold.

The iJoy Diamond is primarily made of zinc alloy and has a glass-like material panel on the front and back that is designed like a multi-faceted diamond. The cool thing is I never thought that a diamond design would look so good on a mod and iJoy designed it so well.

On the front of the mod, you will see the large OLED screen that seamlessly blends with the front diamond shaped panel which gives the device a very unique and classy look. On the lower part of the front panel are the up and down buttons and a micro USB port for charging and firmware upgrade.

On the side of the device, you will see a large fire button that is shaped like a diamond as well which is nice since it makes the overall design consistent. On the back is the magnetic battery door that can house two 20700 batteries but you can also use two 18650 batteries using the battery sleeves included in the kit and on the bottom are battery venting holes.

The atomizer included in the kit is the Captain X3S tank that features dual adjustable airflow and a sliding top fill design. The tank is 25 mm in diameter and has an e liquid capacity of 4.2 ml. Overall, I like the design so much since it looks very classy and elegant which truly sets it apart from the design of most mods on the market right now.

The Captain X3S tank comes with two coil heads. Pre-installed is the X3-C1 coil head that has a resistance of 0.4 ohm and is rated to use between 60 watts to 90 watts. The other included coil head is the X3-C2 which has a dual coil build inside that has a resistance of 0.3 ohm and is rated to use between 60 watts to 100 watts.

These coil heads are pretty much similar in terms of giving an excellent flavor and vapor production but the X3-C2 dual coil 0.3 ohm can give a denser and bigger clouds at higher wattages. The iJoy Diamond has a maximum output of 234 watts and not only supports variable wattage but also temperature control so you can use coil builds made of nickel, stainless steel, and titanium.

It also supports TCR and power curves if you want more personalization to your vaping style. The Captain X3S tank has dual adjustable airflow so you can set your airflow to your liking. You can easily adjust it if you want a tight and restrictive drag or an open type for an airy drag to get that nice big clouds.

Multiple configurations can be made on the iJoy Diamond kit. Aside from its support for dual 20700 and dual 18650 batteries, the iJoy Diamond has all the features all the advanced vapers need and with its 234 watts max output, it will be able to fire any coil builds you want.

The iJoy has a centered 510 connection and can support any atomizers up to 34 mm without overhang so compatibility with other atomizers will not be an issue. The Captain X3S comes with a wide bore 810 drip tip so any other 810 drip tips can be used and the kit comes with a 510 drip tip adapter for the 510 drip tip fans out there.

The only thing I don’t like about this kit is it doesn’t include an extra glass tank so you have to be extra careful with how you handle your Captain X3S tank.



Since the iJoy Diamond natively uses dual 20700 batteries, it is not the sleekest device on the market but it is not overly huge either. With the Captain X3S tank on, it is 150.6 mm in height, 49 mm in width and 34.5 mm in thickness.

It is not the most portable device on the market but due to its style and classy design, it is a great device to bring in parties or social gatherings especially if you are wearing a suit. It is a good device for traveling as well since it supports battery charging through the micro USB port.
