Got mine today so first impressions only, more updates once I've had a chance to experiment with it.
This my first ever squonker, I wanted a cheap device in case I didn't like it.
The RDA seems cheap and not too well designed. The deck and chamber is too large in relation to the posts and the practical power range. The coils were way below the AFC holes, but with a bit of wrangling I managed to raise them up in line. The plastic top-cap could be an issue once the coils are up closer to it. The stock build in there came out to 0.25 ohms. It actually vapes pretty well, ok vapor production and OK flavor. The vapor density isn't too great but this is probably due to the size of the chamber.
- Lightweight and well constructed for the price
- The battery cover looks a bit flimsy, but the rattle adjuster works well enough
- The juice bottle cover is going to get lost I'm sure
- No point of reference, but seems to squonk pretty well
The main problem with this device is going to be voltage drop which I measured with the above resistance at 0.92 volts which is pretty poor. This meant that with a fresh battery I was only getting about 46 watts which is a bit anemic for me.
I plan to rip out the stock coils and replace with some parallels down around 0.2 or possibly a touch lower.
I put a 0.2 ohm dual parallel in my Velocity atop this. Some improvement, but not enough as lowering the resistance also increases what is already a horrible voltage drop.
They should have dropped the protection electronics, gone fully mechanical and spent the savings on making it more usably electrically efficient.
It's a good little device, but no good for me. So it's off to the drawer of abandonment as I can't imagine finding a new vaper who would want/need it.
Definitely sounds like a possible build problem on the Derringer,it should be a huge improvement over the stock rda.Bfed a derringer clone and an old tobh clone for it, and bought a velocity v2 with sqounk pin. Derringer works ok(probably just a build problem), tobh isnt much better (same reason)and the velocity pin is too short to work right..... :'( stock atty is best of the 4 so i guess ill keep with it. Airflow and sqounk holes work fine, deck is a little small for my liking but i can build it no prob.
I'm a mtl vapor. Have cyclone on top and 1 ohm coil. Works well, so far.
It's kinda funny, but for the past month I've mostly been using Kangers Subdrips with me Subdrips.
Yeah, ain't the best airflow, but it doesn't leak as easily as say Tsunami24 and is way more easy to squonk right than say Velocity2.
Starting to think you simply can't get an good atty if it's a hybrid in nature, way too much wasted space with velocity-style posts and deep juicewells.
All Kanger needs is to make optional topcaps dedicated for mtl losing the velocity-deck.
Solid 17 mm mtl-atty wouldn't go a miss either.

That's what i sort of figured.The stock atty was pretty decent,but i have been using bf Derringers and a few bf stumpy's and the stock atty just doesn't come close to either of those.You and i was right, just a build problem. Changed from a 10wrap 3.5mm 26awg 304ss contact single to a 5 wrap 2.5mm spaced 304 single and this thing is vapin like a champ. Rayon is wicking like a champ. So much flavor. Mmmm.
