Introducing the Sparrow - Early Bird’s debut into the world of rebuildable tank atomizers. Engineered from the ground up with years of design experience, the Sparrow delivers a fresh and highly functional take on the RDL/MTL experience, tailored for both newcomers and seasoned users alike.
The Sparrow RTA marks Early Bird’s official entry into the world of rebuildable tank atomizers — and it’s a debut that commands attention. While the brand name itself may be a newcomer to the vaping scene, the minds behind it are anything but inexperienced. The Sparrow RTA isn’t the product of trial and error from first-timers; it’s the culmination of years — even decades — of hands-on experience designing, testing, and refining atomizers. The team has been responsible for some of the most respected rebuildables in circulation, and with the Sparrow, they’re bringing that hard-earned knowledge into a new era under the Early Bird banner.
Rather than chasing trends or overcomplicating the design, the Sparrow RTA is a focused, purpose-built atomizer engineered for both restricted direct-lung (RDL) and mouth-to-lung (MTL) vapers. It’s a system crafted from the ground up to deliver genuine performance — not just impressive specs on paper. Every component, from the airflow dynamics to the internal chamber geometry, has been carefully balanced to produce a smooth, consistent, and flavour-rich experience that satisfies enthusiasts who value precision and practicality in equal measure.
Physically, the Sparrow RTA strikes a perfect balance between compactness and capability. Measuring 24mm in diameter and standing 36mm tall without the drip tip, it’s deceptively small but delivers exceptional flavour density and vapor production for its size. The atomizer utilizes a top-to-bottom diffused airflow system, an innovative setup designed to minimize leaking while maximizing flavour concentration. This system provides vapers with hundreds of potential airflow combinations, allowing full customization of the draw to suit personal preferences. Included in the box are eight bottom airflow pins, ranging from 1.0mm to 4.0mm, giving you precise control over the resistance and intensity of your vape. Pair your chosen pin with the adjustable top airflow, and you can dial in everything from a tight, cigarette-like MTL draw to a loose and open RDL inhale.
The build deck is straightforward yet highly efficient — a two-post configuration that comfortably accommodates 2.5mm and 3mm coils. Installation is simple and secure, making it accessible to both seasoned builders and newcomers to rebuildable tanks. The large wicking channels work in harmony with the top airflow design to effectively eliminate leaking and dry hits, even under heavy use. The barrel sections are thoughtfully knurled for grip, so you can easily disassemble or switch between standard and extended modes without the need for tools or frustration.
Every design decision behind the Sparrow RTA reflects a commitment to usability, consistency, and flavour. It’s not about flashy gimmicks or overdesigned parts — it’s about creating a rebuildable that vapers can trust day in and day out. From its leak-resistant engineering to its versatile airflow tuning, everything feels refined and deliberate.
In short, the Sparrow RTA isn’t just another entry into an overcrowded market — it’s a carefully considered piece of hardware built by veterans who understand what vapers actually want. Whether you’re chasing flavour precision, a reliable everyday tank, or simply an RTA that makes building a pleasure, the Sparrow delivers on all fronts. It’s a tank that earns its place in your rotation — not just for its performance, but for the thoughtful craftsmanship behind every detail.
AIRFLOW
At 24mm in diameter and 36mm tall (without included 510 tips), this compact flavour chaser features a Top-to-Bottom Diffused Airflow System, designed to eliminate leaks while offering hundreds of smooth airflow options. Start by choosing one of the nine included bottom airflow pins for your chamber airflow output while dialing in the top airflow intake to get the perfect draw - whether you're chasing a tight, flavorful MTL draw or a smoother RDL hit, the Sparrow adapts with precision.
USABILITY
The Sparrow was crafted with user experience at the forefront - effortlessly install your favourite 2.5mm and 3mm coils with its classic two post deck design. Forget about leaks with its large wicking ports and top airflow design. Effortlessly switch between the standard barrel and the included extended mode without tools or frustration with the hidden knurled barrel on each section. The Sparrow makes simple design choices to create user friendly flexibility.
Early Bird includes a full set of eight interchangeable airflow pins: 1.0mm, 1.2mm, 1.5mm, 1.8mm, 2.2mm, 2.8mm, 3.4mm, and 4.0mm. The smaller pins deliver a tight, cigarette-like MTL draw, while the larger options open up the airflow for a smooth DTL experience. Swapping pins takes just seconds, allowing you to transform the way the Sparrow RTA performs with minimal effort. Paired with the adjustable top airflow system, the setup offers hundreds of airflow combinations, giving you precise control to fine-tune your perfect draw every time.
Designed to impress, built to perform - the Sparrow isn’t just another RTA. It’s the one you'll keep reaching for.
