Geek Vape Griffin 25mm RTA (Top Airflow version) - Rebuildable Tank Atomizer

Geek Vape is a trusted brand name, known to manufacture exceptionally high-quality vaping hardware. From their exceedingly innovative designs, to their meticulous attention to every detail, Geek Vape’s line of devices is truly second-to-none. On the heels of the wildly popular Griffin RTA, Geek Vape has now released the larger version of this sensational tank—the Griffin 25 Rebuildable Tank Atomizer. This marvelous device offers you everything you could ask for in a high-end RTA—style, performance, convenience, and unsurpassed delivery.

In line with all of Geek Vape’s phenomenal products, the Griffin 25 RTA is fabricated with only premium-grade materials, which have been masterfully precision-machined for optimal functionality. The device’s body is constructed with top-shelf 304-grade stainless steel. Consisting of a special blend of alloys, including nickel, chromium, and zinc, the Griffin 25 is exceptionally strong, durable, and corrosion resistant. The set screws are made with 316L stainless steel, while the tank’s insulators are fabricated with USA-made Polyether-Ether-Ketone (PEEK) for superior heat protection.

The Geek Vape Griffin 25 RTA is topped with a stylish 10mm Delrin wide-bore drip tip for competition-level performance, as well as unparalleled heat dissipation. The base of the device houses an adjustable stainless steel contact pin that is plated in pure 24k gold. This provides for unrivaled electrical conductivity, thereby greatly supporting overall performance.

The Geek Vape Griffin 25 RTA’s large 6.2ml tank component is made with high-grade fused silica glass. As one of the purest forms of glass, this amorphous material possesses exceptionally high melting and working temperatures. This enables the Griffin 25 to withstand the heat generated by any type of atomizer coil configuration you choose. The RTA’s fused silca glass is also completely impervious to the acidity found within e-juices, thereby providing for extraordinarily pure, clean, and “true” flavor from your liquids.

Geek Vape brilliantly designed the Griffin 25 RTA with a large, state-of-the-art velocity-style build deck. The roomy 17mm deck features a two-post, side-tension configuration, allowing for an array of complex build styles and coil arrangements. The deck not only allows for intricate dual-coil builds, but with the separate ceramic block, this phenomenal device can be used for single-coil builds as well. The Griffin 25 RTA’s build deck is equipped with large airflow tubes, providing for a direct channel through its core for consummate flavor intensity.

The Geek Vape Griffin 25 RTA has been judiciously furnished with two independent airflow control valves, each serving a specific purpose. The bottom-positioned airflow valve provides for precise air intake regulation, which can be utilized to control the airiness of your hits. The various airflow settings conveniently click into place, thereby affording you the ability to make your hits airier or tighter, based on your preferences. The top airflow adjustment ring helps you regulate the temperature of the vapor that is produced. You can open the valve for cooler hits, or tighten it for warmer ones. These two airflow control valves greatly assist in allowing you to customize your vaping experience to according to your needs.

Adding to the convenience and ease-of-use of the Geek Vape Griffin 25 RTA is its spectacular top-fill e-juice system. As opposed to many tanks that require you to detach it from the battery in order to unscrew the base to fill the tank with liquid, the Griffin 25 can be effortlessly filled from the top by simply unscrewing the device’s upper lid. Moreover, the oversized fill slots allow you the ability to either pour your e-juice in or use a dropper, accordingly making refills quicker than ever.  

In addition, Geek Vape perceptively engineered the Griffin 25 Rebuildable Tank Atomizer with a useful juice flow control valve located at its base. This superb component permits you to regulate the amount of e-liquid that flows to the coils. The ability to adjust the juice flow not only helps reduce flooding and leaking during refills, but is also handy when alternating between e-liquids of various VG-to-PG ratios.

Made with the very finest materials, which are masterfully precision-machined to immaculate perfection, the Geek Vape Griffin 25 RTA is a high-end device that is very affordably priced. It is designed and engineered to provide for easy builds, convenient use, and competition-level performance. Capable of providing truly mind-blowing vapor production and incomparable flavor robustness, the Griffin 25 RTA by Geek Vape is truly in a league of its own.

Rebuildable atomizers (RDAs, RBA, RTAs) and their use pose certain risks that you should familiarize yourself with. All rebuildable atomizers are intended for advanced/expert users only, and not meant for beginner or intermediate vapers. You should have a minimum of 6 months experience with rebuildable atomizers prior to purchasing one for yourself and attempting to use it without the supervision of an expert. You must have intimate knowledge with using multimeters; be well versed with Ohms Law and how it relates to wattage and voltage; be well trained in building atomizer coils and how to properly configure them; and have a solid understanding of electronics in general.

Prior to purchasing and using any rebuildable atomizer, you must make sure that you fully understand the following:

  1. All rebuildable atomizer coils must first be tested prudently with a proper meter prior to it being used, as untested atomizer coils can be extremely dangerous.
  2. Coils that have been improperly configured or are otherwise faulty can blow your electronic device, which can result in serious injury to you and/or your property.
  3. Atomizer coils that have been newly constructed must be tested on a meter, then first used on an advanced personal vaporizer (APV) that has all of the appropriate safety features, including short-circuit protection. Once the atomizer coil has been tested and used on such a device, you can then cautiously use the coil on a mechanical MOD.
  4. Faulty or otherwise improperly configured rebuildable atomizer coils can damage electronic devices, which can result in bodily injury or harm.

By purchasing and using this product, you hereby consent to wholly taking full responsibility and sole liability for the purchase and use of this item.

I've had this RTA for about 2 weeks now and I got the hang of how to build and wick it right from some Youtube videos. It works really well, great airflow, no leaking, great flavor and vapor. Got some of the vandy vape fused clapton wire and it chucks now! Used to have the Avocado and old Griffin, this one it totally improved and way easier to build on. I give it a thumbs up!
