The iJoy Captain 25mm RTA is the rebuildable edition of the popular Captain series, deploying a high-quality machined structure with a user-friendly postless, four terminals with the utilization of the specially design grooved base section. The iJoy Captain RTA measures 25mm in diameter, creatively designed with a grooved section located below the juice reservoir and right above the build chamber. This result in a reduction in heat transmission route and helps prevent the entire structure from heating up during extended use. The tank capacity is 3.8 milliliter, exposed via a brand-new retractable sliding top-fill design. The build deck of the Captain RTA implements a quad terminal postless build deck, featuring a 2.5mm by 2.5mm diameter terminals set into the deck and tightened via side-tension Hex srews. Due to the lack of posts, the design also frees up build space and wicking area with the deep juice well to accommodating large coil structures and creative configurations. Airflow of the Captain RTA features two angled airtubes along with two bottom airtubes integrated within the build deck section, fed by two large slotted external airflow for a wicked vapor production when throttled at high-power. Included in each set is an ULTEM widebore drip tip, utilizing extremely heat resistant and impact resistant material that is perfect for cloud chasers.
