Why Vape with a 21700 Mod
A 21700 vape mod is powered by a single 21700 cell, a larger battery than the common 18650, so it carries more charge and lasts noticeably longer between top-ups. That headroom is why the 21700 has become the standard for sub-ohm box mods and higher-wattage builds. Stay on this page for every mod that takes a 21700, or browse the wider vape mods range.
Single vs Dual 21700 Mods
A single 21700 mod stays compact and pocket-friendly while still pushing plenty of wattage, which suits one-battery convenience. A dual 21700 mod doubles the capacity and the power ceiling, ready for longer sessions and lower-ohm coils. Choose single for portability, dual for stamina.
21700 Mod Types
The 21700 size covers every style of mod:
-
Box mods - regulated 21700 box mods with a screen, wattage control and built-in safety, the most popular pick.
-
Squonk mods - bottom-feed 21700 squonk mods made for RDA users.
-
Mech and tube mods - unregulated 21700 mech and tube mods for experienced builders.
-
Boro and AIO mods - 21700 boro and AIO builds that take a removable pod.

21700 Batteries and Chargers
Most 21700 mods are sold without a cell, so you will need a 21700 battery and a charger to suit. Browse vape batteries and battery chargers to finish the setup. Many 21700 mods also accept an 18650 with the included adapter.
