What’s The Top 21700 Boro Mod Right Now?
When you’re running a single-battery mod, power is always a compromise. You’re balancing portability against runtime, and the moment you start pushing higher wattages, that compromise gets more noticeable.
Swapping to a 21700 cell is the most straightforward fix: it’s a larger capacity battery than an 18650, which means more performance and longer runtime before you’re reaching for a charger.
The catch? In the Boro world, 21700 options are genuinely harder to find.
Most popular Boro mods lean compact by design, and squeezing a 21700 cell into a compact frame takes more engineering than most manufacturers bother with.
The ones that do tend to charge a premium for it.
But they do exist, and a few of them are worth every penny.
The standout right now is the Tek Division Phobos 21700 DNA60 (pictured below), a boutique build that pairs Evolv’s DNA60 chip with a PA12 nylon shell and a full 21700 cell.

It’s not cheap and it’s not aimed at beginners, but if you want all-day battery life without compromising on chipset quality, it’s the benchmark everything else gets measured against.

In our detailed overview of the best boro mods you can buy right now, the Vandy Vape Pulse AIO.5 was listed very near the top. And the reason for this was simple: it’ll run either 18650 or 21700 batteries, it isn’t too expensive, and it looks and functions brilliantly.
Veepon TITA X AIO 60W
The Veepon TITA X AIO 60W is another great option if you’re in the market for a 21700 boro mod, although it is a lot more expensive than than Pulse AIO.5 – the Veepon TITA X AIO 60W retails for $129.99.
Veepon introduces the TITA X AIO, a 60W all-in-one vape mod system with Boro tank and integrated drip tip compatibility. The TITA X AIO features classic styling with a front mounted VP60 chipset, side firing button, and front mounted tank. The tank, screen, and adjustment buttons are hidden behind a removable face plate for a clean look. The TITA X AIO is constructed from stainless steel and aluminum, with a customizable face plate panel. Veepon includes a TITA X Tank with TITA Mesh Coils, which is also compatible with dotStick Coils and Nord Coils. The TITA AIO is powered by a single 21700/18650 battery (sold separately), which can be accessed via a threaded battery door with swing out tab.

Me? I’d keep it on budget and go with the Vandy Vape Pulse AIO.5; in our testing it performed brilliantly across the board. It looks great, either in blue or black, although the black variant, for some reason, seems to have better structural integrity – no idea why, though.

For the money, the Vandy Vape Pulse AIO.5 is a killer setup that is about as versatile as a boro mod can get. It costs better than half the price of the Veepon TITA X AIO 60W, and it’ll run either 18650 or 21700 batteries, giving you the best of both worlds.
