9th Aug 2021 | 20 | upends v

The Katana kit is a box mod manufactured and distributed by the IJOY vape company. The mod takes a vape pen design and features a 3000mAh internal battery with an 81W maximum power output. It is worth noting that the device has specialized modes that come in handy for different types of vaping.

For example, you can choose to vape with the Mouth-to-lung draw system, the variable voltage power mode that comes with the soft, regular, and hard pre-settings. Additionally, there is also a TC mode and many more.

The IJOY Katana is run using the IWEPAL chip and is available in seven varied colors. This device is quite remarkable, and with this review, we will try and find out how the device performs among the multitude of box mods available in the market. 

Specifications and features of the Katana kit

The external case of the design is a sturdy and ergonomic zinc alloy build. It stands at 94.5mm tall and with a width of 30mm. This outer casing conceals the high-power 3000mAh battery that is built-in. With such a strong battery, the IJOY Katana can give a maximum of 81W power output.

Moreover, there are various modes that you can operate the device on. These modes include power mode, TC mode, Bypass mode, and specialized mode.

The iconic IWEPAL chip from IJOY tops the performance by making the mod very responsive and quick to action. The best specification is the 0.91 inch OLED display screen that eases the operations.

Build and design of the IJOY Katana kit

The IJOY Katana operates more like a vape pen in place of a box mode. It has a long and slender shape that looks more like a box but has curvy edges and sides. The device is not extensively large going by its size, but it is somehow heavier than other vape mods.

The 120gram weight makes the device feel more solid in hand, and you would even feel scared if it happened to drop. The design quality is magnificent, and it is doubtful to get any mechanical defects on the device.

The curvy edges of the IJOY Katana kit make it easy to hold. It fits perfectly in hand and is very comfortable when pressed against the palms. The fire button is also strategically placed, so you do not have to struggle to use the box mod. The smooth and refined finish makes it look mechanically sound, but you must be careful it does not slip out of your hand.

The design looks very much industrial, and the stainless steel selection seemed to be more functionally viable. The other available colors are more fun for people who like colorful devices that are very noticeable. The colors make the mod look more sociable, and the colors can go a long way in adding to the attractiveness. 

Apart from the branding found on the bottom of the unit, the IJOY Katana has a rather plain design that does not have any branding. The mod and the OLED display buttons are found on one side of the kit, and the other sides do not bear any features. The top-fill design is assisted by a 510 connector that uses springs.

The buttons used for firing and adjustments are all rounded and look very nice. However, you would happen to feel a little rattling when you touch the controls, and the hollow spring-like sound they make would detract so much from the build design expectations. The buttons are nice to press and are equally click but need some pressure for them to respond.

Battery and charge of the IJOY Katana kit

The Katana kit utilizes an internal 3000mAh battery. Considering that it fires up to 81W, this is a good powerhouse. You could easily vape for a day and a half or even two days when heavily vaping on watts between 60 and 70.

The battery is favorable to use on the go because you can use the USB port to charge instead of the battery removal process that is common with the other IJOY devices. Charging the device does not take long, and it could take less than two hours to go from flat to full.

Performance of the Katana

The IJOY Katana is a very dependable device and can also be a well-performing box mod. The temperature control features make it a very easy-to-use device, especially with the variable wattage modes for vaping. When you press the firing button, it fires instantly, and it gives a very accurate wattage output. 

If you are a seasoned vape user, you will notice that 70W is the best wattage for this device and is the best option for many tanks and coils. The battery life is impressive, and the 3000mAh battery backs this.

It is okay to think that the Katana would be a good backup for your device when the main battery runs out. The battery is good on end. Unfortunately, there are scarce units with such performance. 

The mouth-to-lung mode has good compatibility with the MTL tanks. However, the mouth-to-lung feature should not ramp up more than 25w because this is the most suitable power range for the BSKR and could be a little low for another type of tank. With a proper firmware update, this issue can be resolved.
