Geekvape Eagle Hybrid Sub Ohm Tank and RTA Review

Bill has a vape on the GeekVape Eagle Hybrid which is a sub ohm tank and an RTA in one. Find out what he thought about it...

Geekvape Eagle

GeekVape Eagle Intro

2015 was the Year of the Sub-Ohm Clearomizer Tank. The Uwell Crown, SMOK TFV4, Freemax Starre, and Sense Herakles led that revolution. 2016, however, is the Year of the RTA. Sub-Ohm Clearo Tanks aren’t dead, by any means, but they are a little ho-hum now compared to RTAs.

The Eagle is GeekVape’s attempt to combine the best of both worlds — sub-ohm clearos and RTAs. How? By combining a tank that’s designed like an RTA with the convenience of a sub-ohm clearo.

Geekvape Eagle Taken Apart

The Eagle is essentially a Griffin RTA. The two tanks appear nearly identical — same design, same size, same top fill method, same dual airflow top and bottom (although the Simplified Standard version has only bottom airflow through cyclops slots). The main difference is that the Eagle uses “hybrid” heads. Rather than the typical sealed factory coil heads that sub-ohm clearo tanks use, Geek Vape has designed an entire line of “disposable” deck-based coil heads that come pre-built in many wire types, including some exotic Clapton wires. The heads are even pre-wicked.

GeekVape calls these disposable heads “HBC,” for Hand-Built Coils. The decks are encased and simply screw into the Eagle base, which makes them like sub-ohm clearo heads, but they’re built like RTA decks.

As good as they are, most sub-ohm clearo tanks are still a notch below the new generation of RTAs in the quality of vaping experience provided. RTAs tend to give slightly better flavor and vapor production.


Geekvape Eagle Versions

The GeekVape Eagle heads bridge that gap and provide the vaping experience of the best RTAs, but without the necessity for building coils on the deck.

Performance is as good as the Griffin, but with deck heads that can be swapped out easily, or dry-burned and re-wicked, or even rebuilt entirely (assuming that you have the proper hex driver for the grub screws).

Hybrid designs sometimes fall short, failing to achieve the quality of either design they’re trying to marry. With the Eagle, Geek Vape has produced a brilliant hybrid that really does combine the best of two worlds.

One Gripe

Geekvape Eagle Coils

My sole criticism is that the heads, which are called Hand-Built Coils (HBC) are inconsistent. They look hand-made, often with imperfect spacing or uneven alignment. They vape great, but they look a little funky.


If you like building your own coils and own a Griffin or any other superior RTA, you don’t need an Eagle. If you like the convenience of having a manufacturer do the work for you, however, the Eagle is brilliant.

Also, many vapers — even those who enjoy building coils — won’t own the range of wire types that GeekVape offers with their pre-built heads for the Eagle. That’s nice.

Highly Recommended.

Mine leaked like crazy when I tried it out! I couldn’t even get a good vape off of it! Its just sitting on my desk waiting for me to either rewick the HBC or buy some new ones and try it again. Do you have any idea what could be the cause of the leaking?


Bought one about 1 week ago. Have the same leakage problem. I have to make sure the tank airflow is closed or will leak like crazy. Also couldn’t get a good vape until the coil heated up. See this tank sitting in a drawer until a better something comes out. No need for the internal tank airflow so will definitely make sure that this option is not there on any future mods. Very disappointed given all the hype.


If you close the juice flow and airflow while refilling in stops this. It’s to do with pressure when you screw the cap back on.
Also you have to be really vigilant on how well everything’s screwed together, make sure the coils just right, no oil on the seals etc.
It’s good but it’s a lot of work.


I will give it a try. Appreciate the info.
