Vaporesso Armour OCTA

This listing is the Armour OCTA mod only. No tank and no coils are included, and batteries are not in the box either. Before you get going, there are a few things worth sorting first.

Batteries

The Armour OCTA takes two 18650 cells, sold separately. Use a matched pair, meaning same brand, same model, same age, purchased and cycled together. Never mix old and new cells, and avoid mixing brands. The mod features voltage surge protection that cuts output if the difference between the two cells exceeds 0.9V, which is a useful safety net, but proper battery matching is still your first line of defence.

Slide the battery door open, insert both cells observing the polarity markings inside the tray, and click the door closed until it seats firmly.

First Power-On and Controls

Once batteries are in, the Armour OCTA powers on with three quick presses of the fire button. The same three-press action cycles through the main menu where you can select your mode (wattage, eco, temperature control for various wire types, boost, and pulse), adjust brightness, set a puff counter limit, and choose a display theme.

The physical lock slider on the side of the mod is worth using whenever the device goes in a bag or pocket. Sliding it to the locked position prevents accidental firing entirely, which matters on a 220W device. The V2.0 Overtime Protection also cuts output after a 10-second continuous press (Level 1) and powers the device off if that happens twice within two minutes (Level 2).

Pairing a Tank

The Armour OCTA uses a standard 510 connector, so it will accept most 510-compatible sub-ohm tanks. It is designed to pair with the Vaporesso iTank T, though that tank is not included with the mod alone. If you are running your own tank, check the coil resistance is within the mod's operating range and set wattage to match your coil's recommended window.

Charging

Charge via the Type-C port at DC 5V/2.5A. The port has a silicone plug to maintain the mod's weatherproofing, so keep that seated when charging is not in progress. The mod includes overheat charging protection that stops charging if the temperature exceeds 75°C, which keeps long sessions safer. External battery chargers are an alternative if you prefer to charge your 18650 cells separately, which is common practice among regular external battery users.

E-Liquid Recommendation

Because this is a mod only, liquid choice depends entirely on the tank and coils you pair with it. If you are using the GTi 0.2ohm or 0.4ohm dual mesh coils that accompany the iTank T, those are sub-ohm, high-power coils suited to direct-to-lung vaping. Use a high-VG e-liquid, 70VG or above, ideally a 50ml or 100ml shortfill. Freebase nicotine at 3mg or 6mg is the standard call at this power level. Nicotine salts are not recommended with sub-ohm, high-wattage setups.
