Hcigar Derringer from Canvape
This is the Hcigar Derringer tank as I received it (actually, it was in a zip lock style bag). The case is very plain, and included: 2 Kanthal pre-made coils, some rayon wicking material, spare O rings, spare screws, and a 1.1 mm allen key (the post screws are allen heads).
This is one of the smallest drippers available. Even with the drip tip on, it's only 25.3 mm in height. The word from users who have tried this tiny tank is really good. So, I had anticipation of a great vape when I got this. And, gheez I feel foolish with this test.
Most of you know my challenges with hand tremors. It's only been a few weeks since my first coil build after many months where I was unable to build. So, it takes me awhile to get a decent coil and get it all wicked properly. And, here's where I feel foolish. After all the time spent building the "perfect" coils (two of them, each around 0.6 ohms), I went ahead and mounted them. I tested fired, adjusted, and got the perfect burn. I then used some of the finest Japanese organic cotton and got a perfect wicking all in place. The coils are on an angle, plenty of space to the deck wall, the wicks are designed to saturate from the bottom, and do some light feeding from the top. And, then I recalled I hadn't cleaned the tank system before I started. This has to be a first for me, I am usually quite diligent super cleaning any rebuildable. I went ahead and saturated the wick anyhow, and did a vape. I half expected to get a machine oil taste and tolerate that for a few tankfuls – that would be my penalty for the foolish mistake. But, surprise, no off tastes. Thanks Hcigar for cleaning this properly ...
At the left are a series of photos that show all of the components that make up the Hcigar Derringer. The quality of these parts is very good. The only concern I had while working with this is that the negative posts do not have holes, they appear to be cut with a saw blade with a very narrow band of metal left. I was cautious in tightening the negative post screws ... I was that concerned about breaking those top parts off. The holes were large enough for my 26 gauge wire. Even the double legs in the center post had plenty of room and likely are large enough for twisted 26 gauge. By the way, you can click on these pictures, they will open up the larger version.
In the second and third picture, note that there are two parts that make up the "tank". One is an inner sleeve that has three holes on opposing sides that line up with a dual coil build. There is also a third set of three holes for a single coil build. You line up the inner sleeve with the coil(s) and then line up the inner sleeve holes to the outer tank slots. The inner sleeve sits on its own ledge on the base. The air holes in the sleeve line perfectly with the coils. The air holes are raised above the base liquid well ... it actually adds some measure of protection against leaks. The outer tank slips over the inner tank and sits on its own led also on the base. It's perfectly positioned that way, and you can adjust the air slots to match the inner sleeve air holes. You can have it wide open, or close off the air holes as you want. The inner sleeve stays put if you adjust the outer tank air flow. It's a nice system.
The 510 connector threading is very smooth and the 510 pin is adjustable with a flat screwdriver. The 510 pin is copper as is the center positive post – you'll get minimal power loss.
There is ample space to work on this deck too ... you'd think with a tiny body, there would be less space. It's actually the tank portion is makes this appear tiny. The base is about the same size as even as large tanks. The post holes are above the deck edge. The holes are not offset, though. You will end up having to bend the legs slightly if you want them perfectly horizontal (plus, you might actually have to raise the center post side a little to get it over the edge – the angle is bit extreme on a build with 6 or less wraps). That being said, it was a pleasure working on this base, even with some of my limitations. Even cutting the legs after tightening the coils down is not an issue.
I ended up leaving the coils on an angle. The side of the coil that has a leg insert into the positive post is facing downwards towards the base deck. So, I decided to make a wick that was long enough to insert into both coils, with the center portion wrapped around the positive post to capture the liquid when dripping in. The other side exists on the down facing portion of the coil, and is then reversed in direction, loosely, so that it tucks back under the coil body ... that should get plenty of juice exposed to the inner coil and the lower outer coil.
And, it works. The flavor production from this setup is just incredible. It's as pure a flavor and taste sensation as I've ever had on any tank. And clouds ... man, I created a small weather system in my house while vaping this tank. It's awesome. I don't really think of myself as a cloud chaser, I really chase for better flavor.
Before wrapping up this test and review, I want to talk about the drip tip included with the Hcigar Derringer. Not only is this tank tiny, the drip tip is actually a wide bore, but the shortest I have ever seen or used. I measured its total height above the tank insertion point to be 7.9 mm.
The coils I used on this ended up being close to 0.6 ohm resistance each. The only advanced personal vaporizer I could use with this is the Vaporshark rDNA. The Vaporshark shows this build with a finished resistance of 0.24 ohms. My dual coil setups are usually around 0.3 ohms, so this must have more to do with the shorter legs that I decided to use to avoid the deck edge. Regardless, it is a bit lower than I prefer, but it fires nicely, burns evenly, tastes awesome, and generates a nice cloud – even with the Vaporshark limitation of 40 watts. The IPV Mini 2 initially did not fire this coil reporting it as "low res". After vaping it for a few minutes with the Vaporshark, I tried it again on the IPV Mini 2 and it worked. Not sure why it didn't initially, but I was pleased to be able to try this at 70 watts. Wow, flavor is about the same, the vape is warmer, and the clouds shield me from watching the TV for minutes. LOL.
Despite the increased wattage and the tiny size of this tank, the vape did not get overly hot. I was actually surprised at how cool a vape this was, even at 70 watts.
So, what's the verdict? Is it worth it? This is definitely a keeper. I have two RDA's that I will not part with – that's just climbed to three. This is a really well constructed and well designed tank. I like the inner sleeve and outer tank combination, it actually helps prevent leaks. I even removed the inner sleeve and put the outer tank back on ... it works and dramatically increases air flow. The flavor is incresed very slightly, and cloud generation is nearly doubled. This quite a versatile tank and rather than call it tiny, from now on I'll call it stealthy. It stealthy, and powerful.
