iJoy CAPO 100W Kit Preview | Because why use two batteries when one will do?

A single battery box mod kit that is capable of dual battery performance.


iJoy CAPO 100W Kit Intro

iJoy is not afraid to bend the rules when it comes to box mod designs. Their decision to create a device that is primarily operated by dual 20700 batteries is surely evidence of this and the success of the Captain PD270 seems to have reinforced this choice.

iJoy continues along this trend with their recent addition to the line, the CAPO 100W Box Mod Kit.

Battery size matters

Comprised of the iJoy CAPO 100W Box Mod and the Captain Mini Sub-Ohm Tank, this hip setup is the first of its kind and is designed to work with high-rate, 21700 cells. It is this design feature that allows iJoy to offer users a 100 W power maximum and an extended battery life that is “reportedly” equivalent to a comparable, dual 18650 battery device.

While “reported battery levels” is hardly concrete proof of this claim, it stands to reason that a 3750 mAh battery will generally perform much better than a standard 2200 mAh cell, so the statement does hold some validity. At the very least, you can be assured that your device won’t be depleted after only a few short puffs at maximum wattage levels.

Thankfully, by some pure stroke of marketing genius, iJoy has included the required 21700 battery with the kit. This means that you can now compare its performance against your standard 18650 cells prior to drawing your own conclusion. Plus, if you then decide to remain faithful to your 18650s, it comes with a nifty adapter that makes this 100% possible. A total win-win!

This powerful, single battery box mod is truly the first of its kind.

Visually speaking, the kit adopts a similar styling to the original Captain PD1865 and PD270 devices, with an oversized, rectangular firing button and front-facing OLED screen. It also has a compact, Pico-esque form factor with a screw top battery bay for easy access.

The paired Captain Mini Sub-Ohm tank has a notable visual tie in to the mod and offers an average-sized e-juice reservoir that holds either 2 mL or 3.3 mL as preferred. This capable platform incorporates a thread-less coil system for added simplicity. It utilizes pre-made coils rated for use in the 30-60 W and 80 W power range. Moreover, its unique, grooved tank chassis assists prevents overheating of the unit while in use.

If the CAPO 100W Kit performs as advertised, it could easily become the new standard for compact box mod setups within the market. But since it is unlikely that veteran vapers will willingly throw out their old 18650 cells in favor of this setup, it may still be a while before we see 21700 box mods become the new norm. Do YOU think they will catch on?

A marketing manager by day and an avid reader – and vaper – by night, I came into the vape scene almost by accident and have never looked back. You will find me in sunny South Africa where I am mostly always curled up on the couch with a good book and a fruity vape. At other times, I am known to indulge my unhealthy obsession with musical theatre and live comedy shows, in that order.

    Love my Capo 100.I can play around with it, set it for nice clouds or for flavor depending on my mood. At home I normally go for flavor around 50-60 high airflow (I’m a stay at home mom and rarely leave the house other then taking my kids back in forth to and from school). When I’m out ( rare) I go for clouds unless someone wants to try my flavor.
    Down fall, I’m a light user but still having to do a full charge around midday. I use the .3 coil, high airflow and I’m having to change the coil twice a week but I’m still having trouble with it staying flavorful. I use 70/30 zero nicotine, short hits 3-5 seconds. Why won’t it produce good flavor? It just taste bland even though I’m buying from highly recommend companies online.
    This is my very first vape ever. I absolutely love the convenience of it compared to my friends’ and family and it has helped me quit smoking those nasty cancer sticks. But I want to be able to have flavor instead of tasteless hits. Please, tell me what I need to do.
