Leaks, durability, and real-world use
Community threads about dual-battery kits often blame “the mod” when the tank o-rings, overfill, thin juice, or sideways storage are the real issue. No tank is magic — fill correctly, seat coils, and wipe contacts. See Why DTL Tanks Leak (and What Actually Helps). OCTA’s TPU tank protector and sealed MOD design help daily abuse; they do not repeal physics. Protection ratings are lab conditions on the MOD — not a license to swim with a filled tank.

Q: Is ARMOUR OCTA the same as ARMOUR ULTRA?
A: No. ARMOUR OCTA is a dual-18650, 220W kit with iTank T and GTi Dual Mesh. It is not a 5500mAh built-in / 100W device. Use only OCTA specs on this page.
Q: What batteries does ARMOUR OCTA use?
A: Two flat-top 18650 high-drain cells (sold separately). It does not include batteries and does not use a built-in pack.
Q: Is ARMOUR OCTA waterproof?
A: The MOD is rated IP68 (1 m / 30+ min) and IP69K (100 bar / 85°C) under lab conditions. Keep the tank sealed, avoid charging when wet, and follow the manual — ratings are not an invitation to submerge a filled kit.
Q: ARMOUR OCTA vs Geekvape Legend 5 — which should I buy?
A: Choose OCTA for 220W, IP69K-class MOD protection, Battery Guard, and GTi Dual Mesh at from 64.90 USD. Choose Legend 5 if you specifically want its 1.08″ UI, A-Lock ecosystem, and Z-coil retail availability.
Q: Which coils fit the iTank T on ARMOUR OCTA?
A: GTi coils only (Dual Mesh and Mesh options such as 0.15Ω–0.5Ω). GTX coils are not compatible.
Q: Does ARMOUR OCTA support 21700 batteries?
A: No — OCTA is dual 18650. For dual 21700 / 18650 flexibility in the ARMOUR line, see ARMOUR Max.
Q: Will the tank never leak?
A: No honest brand can promise zero leaks. Correct fill level, o-ring condition, juice thickness, and storage orientation matter as much as hardware. Read our DTL leak guide for habits that actually help.
