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.
Choosing the Best 21700 Vape Mod
The best 21700 vape mod comes down to output, build quality and how often you vape. Well-regarded 21700 ranges include the Geekvape Aegis, Lost Vape Centaurus, Lost Vape Thelema, Asmodus and Dotmod, each with regulated single and dual options. For the top tier, see the high end vape mods.
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.
