The Knight AIO by Smoant represents their flagship All-in-One design in the well thought of Knight Series. This isn't your typical AIO device – it's a superbly built piece of kit that delivers 90 watts of power through the advanced ANT chipset, whilst maintaining the versatility of Boro tank compatibility and the convenience of a single 18650 battery.
What stands out is the 0.49" OLED screen that provides clear device information, paired with 8 different output modes for complete customisation. The Smoant Knight pairs with their K series coils with the inclusion of 0.15Ω and 0.4Ω mesh coils, but these can also be purchased separately if you prefer a more restricted draw. The Knight AIO allows for DTL through to a loose MTL vaping, adapting to your preferences with precision that cheaper devices simply can't match.


The well-tuned ANT chipset handles the heavy lifting, automatically identifying coil types and selecting optimal power output. The chip adapts to different resistances and provides stable, consistent power delivery. Temperature control works properly with support for various wire types.

Unlike many AIO devices with built-in batteries, the Knight AIO uses removable 18650 batteries. Smoant fans will appreciate this return to removable power - no waiting around for charging when you can just swap in a fresh battery. The magnetic battery cover makes changes quick and secure, whilst the 2A fast charging gets you back up to full power when needed.

The boro tank system opens up plenty of possibilities. You can stick with the included Knight AIO tank or swap in any compatible boro tank for different vaping styles. Refilling is straightforward thanks to the dual fill ports, and the PCTG construction provides good flavour purity and durability.

Smoant has developed two new coils specifically for the Knight AIO. The K-4 0.2Ω and K-5 0.15Ω coils offer different resistance options and airflow characteristics, allowing you to fine-tune your vaping experience. The full K Series compatibility means you've got plenty of coil choices for different styles (0.15/0.2/0.3/0.4/0.6Ω).

The 0.49" OLED screen provides detailed information about your device status without being overwhelming. Battery level, wattage, resistance, and mode selection are all displayed clearly. The interface is intuitive enough that you won't need to dig out the manual every time you want to change settings.

At 96.4 x 51 x 26.3mm, the Knight AIO strikes the right balance between capacity and portability. In use, the device feels reassuringly solid without being bulky, and the ergonomic design sits comfortably in your hand.

If you're looking for a proper AIO that doesn’t limit your options, the Knight stands out. It’s got serious power, full Boro compatibility, and great coil options, all in a solid, well-built device. Whether you're using bridges or stock coils, it’s a setup you’ll get the most out of every day.
