Along the way, we’ll cover safety essentials, maintenance routines, and advanced tips like squonking. Whether you’re just switching from prebuilt coil tanks or starting your first RDA build, this blog will give you the confidence to use your Hellvape device effectively and safely.

Who makes Hellvape gear & which Hellvape RDAs are popular

Hellvape, founded in 2016, quickly established itself as a respected name in the vaping industry, particularly in the rebuildable atomizer market. The company is best known for its collaborations with designers and reviewers that produced user-friendly yet performance-driven RDAs. The Dead Rabbit RDA remains Hellvape’s flagship series, with successive versions like the Dead Rabbit V3 improving airflow, build deck space, and squonk capability.

Some of Hellvape’s most popular RDAs include:

• Dead Rabbit V3 — A 24mm dual-coil RDA featuring a raised “rabbit ear” post system, simplified coil installation, and excellent flavor from its adjustable top-side airflow.
  
  

• Drop Dead 2 RDA — A post-less dual-coil deck with honeycomb airflow for smoother inhalation and versatile tuning.
  
  

• Dead Rabbit Max — A larger 28mm RDA designed for high-powered builds, aimed at advanced users chasing big clouds.
  
  

What makes these RDAs so enduringly popular is their balance of beginner accessibility and customization. Wide build decks, strong flavor performance, and squonk compatibility make them an excellent entry point into rebuildables.

Tanks vs RDAs: which is right for a beginner?

Before choosing your first setup, it’s important to understand the difference between tanks and RDAs. A tank is a refillable atomizer that uses replaceable coil heads and has a built-in e-liquid reservoir. This means convenience: you fill once and vape for hours without having to drip liquid manually. Tanks like Hellvape’s Fat Rabbit and Hellbeast series often use mesh coils rated for wattage ranges (for example, 60–80 watts), making them reliable and easy for beginners.

By contrast, a Rebuildable Dripping Atomizer (RDA) is designed for users who want to build their own coils. RDAs do not have large juice reservoirs; instead, you drip e-liquid directly onto the cotton or use a squonk mod with a bottom-feed pin. RDAs excel in flavor clarity and cloud production but require more frequent attention and building knowledge.

For true beginners, tanks offer a smoother entry into vaping because they eliminate the trial-and-error of coil building. However, those who enjoy tinkering and want to save money in the long run often transition into RDAs. A practical approach: start with a tank, then pick up a beginner-friendly RDA like the Dead Rabbit once you’re comfortable.

Anatomy of a Hellvape RDA and of modern sub-ohm tanks

Understanding your device’s anatomy is the first step toward mastering it.

Hellvape RDAs are typically composed of:

• Drip Tip & Top Cap: Where you inhale vapor and adjust airflow.
  
  

• Airflow Control Ring: Slots or honeycomb holes that fine-tune flavor versus cloud production.
  
  

• Build Deck: Where coils are mounted. Decks vary — post systems like the Dead Rabbit’s “rabbit ear” posts make coil installation easier.
  
  

• Juice Well: Holds a small amount of e-liquid.
  
  

• 510 Pin: The connector to your mod, with many Hellvape RDAs shipping with both a standard and a squonk pin.
  
  

Sub-ohm tanks, on the other hand, usually include:

• Drip Tip: Mouthpiece, often removable.
  
  

• Top Cap/Fill Port: Modern tanks feature slide-to-fill or twist-open mechanisms.
  
  

• Glass Reservoir: Holds e-liquid, typically 2–5ml.
  
  

• Coil Head: Pre-built coil and wick that screws or presses into place.
  
  

• Airflow Base: Adjustable slots to tune draw tightness.
  
  

• 510 Connection: Standardized fitting for mods.
  
  

Each part impacts performance. For example, airflow placement directly affects flavor, while deck size determines how easy it is to install coils. A clear understanding of these parts helps troubleshoot issues later.

How to set up a Hellvape tank (filling, coil install, priming) — step by step

For beginners, starting with a Hellvape sub-ohm tank is the simplest way to begin vaping. Here’s a streamlined setup process:

1. Unbox and inspect: Check for cracks in the glass and make sure O-rings are seated properly.
   
   

2. Install the coil head: Screw or press the coil into the base of the tank until snug, but do not overtighten.
   
   

3. Prime the coil: Drip 4–6 drops of e-liquid onto the visible cotton ports and center of the coil. This prevents dry hits.
   
   

4. Fill the tank: Open the top cap or slide-fill port, pour e-liquid into the reservoir, then close securely.
   
   

5. Wait and saturate: Let the tank sit for 5–10 minutes to allow full wicking.
   
   

6. Start low: Set your mod to the lowest recommended wattage printed on the coil, then gradually increase until you find your preferred flavor and vapor balance.
   
   

Troubleshooting tip: If you notice leaking after setup, recheck that the coil is seated tightly and airflow is closed when filling. Dry or burnt taste? The coil may not have been primed enough.

Building safe, reliable coils for Hellvape RDAs

Building coils is where RDAs shine, but safety and precision are crucial.

Coil materials: Beginners often start with Kanthal A1 (durable and forgiving) or Ni80 (Nichrome 80), which heats faster and is common in Hellvape’s included coils. Stainless steel (SS316L) can be used in both wattage and temperature control modes.

Resistance targets:

• Single coil round wire builds: 0.3–0.6 Ω (moderate wattage).
  
  

• Dual coil builds: 0.12–0.4 Ω (higher wattage, bigger clouds).
  
  

• Always match coil resistance to your device’s capabilities and ensure your batteries can handle the current draw.
  
  

Step-by-step build process:

1. Wrap wire around a 2.5–3mm rod to form 5–7 wraps.
   
   

2. Insert coil leads into the posts, trim excess wire, and tighten screws evenly.
   
   

3. Dry-fire at low wattage to remove hotspots (glow should start from the center outward).
   
   

4. Adjust with ceramic tweezers until the glow is even.
   
   

5. Recheck resistance with an ohm reader or regulated mod before wicking.
   
   

Example starter build: The Dead Rabbit V3 often ships with fused Clapton Ni80 coils, which land around 0.18–0.25Ω in dual configuration. Start around 55–60 watts, then adjust.

Wicking RDAs and tanks: step-by-step for reliable flavor and fewer leaks

Even the best coil won’t perform well without proper wicking.

For RDAs:

• Cut a strip of organic cotton and roll to fit snugly through the coil — not too tight, not too loose.
  
  

• Fluff and trim the ends so they just touch the juice well.
  
  

• Tuck the cotton neatly without stuffing, then fully saturate with e-liquid.
  
  

• Pulse the coil lightly to help juice absorb evenly.
  
  

For tanks (RBAs/RTAs):

• Cut cotton so that tails fit gently into the wicking channels.
  
  

• Too much cotton restricts flow and causes dry hits; too little leads to leaks.
  
  

• Always check airflow seals before refilling.
  
  

Signs of poor wicking include spitback, gurgling, and muted flavor. Adjust the amount of cotton or length of tails until performance improves. Cleaning and re-wicking every few days ensures consistent performance.

Airflow and wattage: tuning for flavor vs clouds

Vaping is highly customizable, and airflow paired with wattage settings determine your experience.

• Flavor-focused vaping: Reduce airflow to concentrate vapor and increase coil saturation. Pair this with moderate wattage within the coil’s recommended range.
  
  

• Cloud chasing: Open airflow fully for more vapor volume, and raise wattage toward the higher end of the coil’s limit.
  
  

For Hellvape RDAs like the Dead Rabbit V3, side/top airflow allows for precision adjustments. Pointing airflow directly at the coil maximizes flavor, while wider settings produce denser clouds. Start at the lower wattage recommendation, test with half-closed airflow, then fine-tune.

Keeping a simple log of wattage and airflow settings helps beginners replicate their best sessions.

Maintenance & troubleshooting: common problems and fixes

Regular care extends the life of your device and keeps performance consistent.

Routine maintenance:

• Rinse tanks with warm water weekly to remove residue.
  
  

• Clean threads and contacts to prevent connectivity issues.
  
  

• Replace coils or cotton when flavor diminishes or burns.
  
  

Common problems and fixes:

• Leaking: Check O-rings, ensure coil is tight, and don’t overfill.
  
  

• Dry hits: Re-prime coil, reduce wattage, or re-wick cotton.
  
  

• Harsh hits: Check for hotspots, lower wattage, or ensure cotton isn’t scorched.
  
  

• Wrong resistance reading: Make sure screws are tight and leads trimmed properly.
  
  

If issues persist, consult the Hellvape product manual or online forums. Replacement parts like glass, O-rings, and pins are widely available.

Safety first: batteries, Ohm’s law, and safe vaping practices

Safety is non-negotiable when working with RDAs and low-resistance builds.

Battery safety basics:

• Use high-amp 18650 or 21700 cells from trusted brands.
  
  

• Check wraps for damage — rewrap or retire damaged batteries immediately.
  
  

• Store spares in protective cases, never loose in pockets.
  
  

Ohm’s law simplified: Voltage ÷ Resistance = Current. For example, a dual coil build reading 0.2Ω at 4.2V will draw 21 amps. Your battery must safely exceed this rating. Always use an Ohm’s law calculator before firing a new build.

Safety checklist:

1. Measure coil resistance.
   
   

2. Verify current draw is within battery specs.
   
   

3. Confirm no shorts.
   
   

4. Fire on a regulated mod first.
   
   

Following these steps protects both you and your equipment, making coil building a rewarding and safe hobby.

Advanced tips, squonking & community resources

Once you’ve mastered the basics, there are ways to take your setup further.

Squonking: Many Hellvape RDAs, like the Dead Rabbit V3, ship with a bottom-feed (BF) pin. Paired with a squonk mod, this allows e-liquid to flow up from a bottle inside the mod directly into the juice well. This gives the convenience of a tank with the flavor of an RDA.

Experimentation: Advanced builders enjoy exploring exotic coils like alien or staggered fused Claptons, but these require experience and high-wattage devices. Beginners should only experiment once comfortable with safety calculations.

Community resources:

• Hellvape official manuals and downloads provide exact specifications and diagrams.
  
  

• Forums and YouTube channels offer step-by-step visual guides.
  
  

• Local vape shops can provide hands-on guidance.
  
  

Keeping a vape log — noting coil builds, resistance, wattage, and airflow — accelerates learning and helps troubleshoot future builds.
