Geekvape Aegis Legend 5 200W: what to know before choosing this kit

The Geekvape Aegis Legend 5 200W kit with Z Sub-Ohm Tank 5 combines an electronic box mod powered by two 18650 batteries with a tank designed for direct-to-lung (DTL) vaping. Beyond its maximum output of 200 watts, this device stands out for its settings, A-Lock switch, IP68 construction and the sliding filling mechanism on its tank.

How does the Aegis Legend 5 work? Which batteries should you choose? Which Z XM Boost coil should you use, and at what wattage? What does the Z Sub-Ohm Tank 5 offer over earlier models? This RoyalCig guide covers the verified specifications and practical advice needed to understand the complete setup.

Key specifications of the Aegis Legend 5 kit

  • Manufacturer: Geekvape.
  • Box mod: Aegis Legend 5, adjustable output from 5 to 200 W.
  • Power supply: two removable 18650 batteries, not included.
  • Chipset: AS Chip 4.0, with a claimed response time of 0.01 seconds.
  • Modes: ECO, SMART, NORMAL, CUSTOM and TC.
  • Display: 1.08-inch colour TFT screen with dynamic lighting.
  • Protection: IP68 certification for the mod and physical A-Lock switch.

Remember: 200 W is the maximum output of the box mod, not a setting that should be used routinely. The selected wattage must always stay within the range stated on the fitted coil.

Aegis Legend 5 box mod: 200 W, AS Chip 4.0 and five modes

The Aegis Legend 5 box mod uses two 18650 batteries and provides adjustable power from 5 to 200 W. Its AS Chip 4.0 manages the settings and power delivery. Geekvape claims a firing time of 0.01 seconds: this is a manufacturer specification, not a measurement carried out by RoyalCig.

What do the SMART, NORMAL, ECO, CUSTOM and TC modes do?

  • SMART: helps select a power output suited to the detected coil, although its recommended wattage range must still be checked.
  • NORMAL: standard operating mode for adjusting power.
  • ECO: favours more economical energy use.
  • CUSTOM: provides access to more personalised settings.
  • TC: temperature-control mode, to be used only with compatible coils and materials.

The 1.08-inch colour TFT screen displays the operating parameters, while dynamic lighting completes the interface. The A-Lock switch on the mod allows it to be locked quickly to reduce accidental activation.

Which batteries should you choose for the Aegis Legend 5?

The Legend 5 uses two 18650 batteries. They are not built into the device and are generally not supplied with the kit. Do not confuse this dual-battery box mod with the Aegis Solo 5, which uses a single battery and has a different maximum output.

For safety and consistent operation, use a quality matched pair of batteries of the same model, capacity and age, in good condition, charged and used together. Choose a discharge current suitable for your use and check that the insulating wraps are intact. An external charger suitable for lithium-ion batteries is recommended for routine charging.

The USB-C port on the mod does not mean that batteries are included. Battery life depends on their actual capacity, the selected wattage and how frequently the device is used; quoting a universal number of hours would be misleading.

To explore the available formats, see the MXJO 18650 battery product page at RoyalCig, and check its electrical specifications before buying.

Z Sub-Ohm Tank 5: sliding top-fill mechanism and top airflow

The Geekvape Z Sub-Ohm Tank 5 is the tank supplied with this version of the Aegis Legend 5. With its 5.5 ml reservoir and adjustable top airflow, it is intended for direct-to-lung vaping with an open draw and substantial vapour production.

How do you fill the Z Sub-Ohm Tank 5?

The Top Push-to-Fill system lets you slide the top cap without removing it completely:

  1. Locate the opening point and slide the top cap using the intended mechanism.
  2. Insert the e-liquid bottle nozzle into the side filling port, without pouring liquid into the central chimney.
  3. Fill without exceeding the tank capacity and close the top cap securely.
  4. If the coil is new, allow the cotton to become saturated before first use.

Geekvape also offers a 7 ml glass for certain Z Sub-Ohm Tank 5 configurations. Capacity and included accessories depend on the version sold: check the actual contents of the retail package.

Why is the airflow positioned at the top?

Top airflow directs air into the upper part of the tank. This arrangement helps reduce the risk of leakage through air inlets located below the reservoir. It cannot eliminate all risks: an incorrectly seated coil, damaged seals or improper filling can still cause liquid to escape.

The Z Sub-Ohm Tank 5 takes compatible Z Series coils and features a replaceable 810 drip tip. You can also view the Z Sub-Ohm Tank 5 product page on RoyalCig.

Which Z XM Boost coils should you choose for the Aegis Legend 5?

Coil choice directly affects the operating wattage range, perceived warmth and amount of vapour. For the Z Sub-Ohm Tank 5, the Z XM Boost versions most often listed are:

  • Z0.2 XM Boost — 0.2 ohm: recommended range of 70–80 W.
  • Z0.4 XM Boost — 0.4 ohm: recommended range of 50–60 W.
  • Z0.15 XM Boost — 0.15 ohm: another Z Series option, generally rated at 70–85 W, to be used only if compatible with your chosen setup.

Important: some editions of the Aegis Legend 5 kit come with a Z Sub-Ohm 2021, while others include a Z Sub-Ohm Tank 5. The coils inside the box may therefore vary. Check the specifications on the actual retail package to establish which coils are supplied.

Never set the mod to 200 W when using a coil designed for 50–60 W. See the available options in the Geekvape Z Series coil pack.

How should you prime a new coil?

After fitting a new coil, fill the tank, let the cotton become fully saturated for approximately 10–15 minutes, then start at the lower end of the recommended wattage range. Increase the power gradually to suit your preference. A persistent burnt taste means you should check the e-liquid supply or replace the coil.

Which e-liquid should you use with the Z Sub-Ohm Tank 5?

The Z Sub-Ohm Tank 5 is mainly designed for sub-ohm coils and a DTL draw. E-liquids with a high vegetable glycerine content, such as a 30/70 PG/VG ratio, are often used with this kind of equipment. However, the best choice depends on the coil, its wicking capability and the manufacturer's recommendations.

Higher power levels generally increase e-liquid consumption. Before using nicotine-containing e-liquid, also check that its strength suits your device and habits. This guide does not replace the precautions set out in the product instructions.

Aegis Legend 5 vs Legend 3: what are the differences?

The two generations have several features in common: 200 W maximum output, two 18650 batteries, AS Chip 4.0 and IP68 certification. The Legend 5 is therefore not simply a power upgrade. The key differences concern ergonomics, settings and the display.

  • Locking: the Legend 3 is known for its touch-sensitive Smart Lock system, whereas the Legend 5 returns to a physical A-Lock switch.
  • Screen: 0.96 inches on the Legend 3 versus 1.08 inches with dynamic lighting on the Legend 5.
  • Modes: the Legend 5 offers ECO, SMART, NORMAL, CUSTOM and TC; their arrangement differs from that of the Legend 3.
  • Tank: the Legend 3 has notably been paired with the Z Fli, while this version of the Legend 5 comes with the Z Sub-Ohm Tank 5.

For someone who already owns a working Legend 3, the main question is therefore which features and tank they prefer, rather than a gain in maximum power. Compare the complete vape kits available from RoyalCig.

Who is the Geekvape Aegis Legend 5 kit for?

With its two removable batteries, extensive settings and airy tank, this kit is primarily intended for adult users already familiar with DTL vaping and handling external batteries. It may suit those seeking a durable device, a readable screen and coils designed for medium to high wattages.

It will be less convenient for someone looking for a compact, lightweight device with a built-in battery or a tight draw similar to mouth-to-lung (MTL) vaping. A maximum output of 200 W does not in itself guarantee a better experience: compatibility between the coil, power setting, airflow and e-liquid matters more.

FAQ: frequently asked questions about the Geekvape Aegis Legend 5

Does the Geekvape Aegis Legend 5 work with 21700 batteries?

No. The standard Aegis Legend 5 version shown here uses two 18650 batteries, which are not included. Do not confuse this model with other Geekvape box mods compatible with 21700 batteries.

Do you have to use the Legend 5 at 200 W?

No. 200 W is the mod's maximum output. The power setting must remain within the range printed on the coil; common Z XM Boost coils for the Tank 5 work at considerably lower wattages.

What is the capacity of the Z Sub-Ohm Tank 5?

The tank featured in the RoyalCig kit holds 5.5 ml. Depending on the package, some versions include a replacement glass that increases capacity to 7 ml.

What is the difference between the Z Sub-Ohm Tank 2021 and the Z Sub-Ohm Tank 5?

The Tank 5 is particularly notable for its attached sliding top cap, whereas earlier versions use different opening mechanisms. Always check the exact kit variant before comparing accessories.

Is the Legend 5 waterproof?

Geekvape states that the box mod has IP68 protection against water and dust under the manufacturer's specified conditions. This does not mean it can be submerged without precautions or that the tank has the same protection.

Which coils are compatible with the Z Sub-Ohm Tank 5?

This tank uses coils from the Geekvape Z Series family, including compatible Z XM Boost versions. Check the exact resistance, wattage range and compatibility listed on the packaging.

Is the Aegis Legend 5 kit suitable for MTL vaping?

The Z Sub-Ohm Tank 5 is primarily designed for direct-to-lung (DTL) vaping and an airy draw. It is not the most natural choice for a very tight MTL draw.

Are the batteries and USB-C cable included?

The two 18650 batteries are not included. Whether a USB-C cable is supplied may vary by kit edition and distributor: check the accessories list in your package.

How can you avoid a burnt taste with a Z XM Boost coil?

Prime the new coil, allow the cotton to saturate, keep enough e-liquid in the tank and follow the stated wattage range. If the taste persists, check or replace the coil.
