GeekVape’s Aegis line includes a range of devices designed with rugged construction and variable output capabilities. The Aegis Mini 5 Mod Kit and Aegis Legend 5 Mod Kit represent two distinct tiers within that lineup — one more compact and the other offering greater power and flexibility. Below is a side-by-side look at how they differ in key technical areas.
Power & Output Range
Aegis Mini 5 Mod Kit
-
Adjustable output from 5 W to 75 W.
-
Built-in 3200 mAh rechargeable battery.
-
Designed for moderate power use within a compact form factor.
Aegis Legend 5 Mod Kit
-
Wider output range from 5 W to 200 W.
-
Powered by dual external 18650 batteries (not included), enabling higher power levels and extended runtime with replaceable cells.
Difference: The Legend 5 supports a much broader power range, suitable for higher-wattage configurations, while the Mini 5 is suited to lower-to-mid-range output within its integrated battery limitations.
Chipset & Modes
Both devices use variants of GeekVape’s AS chipset for regulated power delivery, but they differ in flexibility:
-
Aegis Mini 5: Offers basic modes including VW (Variable Wattage), Power, and Bypass.
-
Aegis Legend 5: Equipped with the AS 4.0 chipset and multiple operating modes such as Smart, Eco, Normal, Boost, TC (Temperature Control), and Custom/Memory.
Difference: The Legend’s chipset provides more advanced power and control options for a wider variety of coils and settings.
Display & Interface
-
Aegis Mini 5: Features a smaller 0.86-inch OLED display showing essential vaping data such as wattage, battery status, and resistance.
-
Aegis Legend 5: Includes a larger 1.08-inch TFT color screen, offering a more detailed readout of settings and status.
Difference: The Legend 5’s larger, color display may make navigating advanced modes and viewing statistics easier.

Tank & Atomizer Compatibility
Aegis Mini 5 Mod Kit
-
Paired with the Z Nano 3 Tank.
-
Tank capacity around 5 mL, with top-fill and top-airflow design.
-
Uses GeekVape B-Coil Series (e.g., 0.2 Ω and 0.4 Ω coils).
Aegis Legend 5 Mod Kit
-
Paired with the Z Sub-Ohm Tank 2021.
-
Larger 5.5 mL capacity and top-to-bottom leak-resistant airflow.
-
Compatible with GeekVape Z Series mesh coils (e.g., 0.15 Ω and 0.4 Ω).
Difference: The Legend 5 includes a larger tank and support for a wider range of high-performance mesh coils.
Durability & Build Quality
Both kits carry forward GeekVape’s characteristic robust Aegis design:
-
Aegis Mini 5: Engineered for everyday durability with water, dust, and shock resistance typical of the Aegis line.
-
Aegis Legend 5: Features IP68 rating for water, dust, and impact resistance — often cited as industry-standard ruggedness for outdoor use.
Difference: While both are durable, the Legend 5’s construction and larger size emphasize rugged capability.
Form Factor & Intended Use
| Feature | Aegis Mini 5 Mod Kit | Aegis Legend 5 Mod Kit |
|---|---|---|
| Output Range | 5–75 W | 5–200 W |
| Battery | Built-in 3200 mAh | Dual external 18650 cells |
| Display | 0.86″ OLED | 1.08″ TFT Color |
| Tank | Z Nano 3 (5 mL) | Z Sub-Ohm (5.5 mL) |
| Chipset Modes | VW / Power / Bypass | Smart / Eco / Normal / Boost / TC / Custom |
| Durability | Rugged design | IP68 tri-proof rating |
Summary: The Aegis Mini 5 Mod Kit is a more compact, moderate-power configuration suitable for everyday use within its wattage range, while the Aegis Legend 5 Mod Kit is designed for higher power, extended battery life, and broader customization with replaceable cells and advanced control modes.
Final Notes
This comparison illustrates how GeekVape’s two kits differ in power capability, control options, display interface, and tank features. The Mini 5 leans toward a portable single-battery integrated design with basic output modes and a smaller display, while Legend 5 expands flexibility with dual batteries, advanced modes, and a larger tank and screen.
