Voopoo Argus Pod Empty Cartridge 2ml Adopting VOOOPOO ITO technology, the ARGUS Pod provides exceptionally smooth flavor and long lifespan. A coil lasts for approximately 14ml of refill liquid. After thousands of tests, the appropriate air duct has been precisely designed. The 4-hole air inlet expands airflow, while the air storage space ensures smooth flavor. The multi-layer sealing works effectively in the ARGUS POD, and the four-hole structure locks the liquid inside. Additionally, the ARGUS G offers differentiated experiences from MTL to RDL, thanks to VOOPOO's intelligent ITO technology. The ARGUS POD tank is compatible with all ARGUS series devices.
