1. GENERAL IMPRESSION.
First impression: HANDY and quite SOLID.
Plastic frame covered with panels made of G10 (kind of fiberglass) or colorful resin - it doesn't sound very solid.
But IT IS! We absolutely do not have the impression of holding a plastic sucker in hand, but we also do not have to worry about soreness in the biceps after a day of vaping :-) The overall experience is just optimal (for me). IF ALL PRODUCERS USED SUCH MATERIALS, THE WORLD WOULD BE BEAUTIFUL. I dare to say that 2x18650 mod cannot be done significantly better than the Swell! It's definitely a mod that you want to pick up. For sure more comfortable than EOS II, probably even better than the WYE200. All the more the other elements do not spoil anything: Fire has a little soft but sure click and works 100/100, similarly up / down buttons, the screen is a razor sharp OLED (in addition colorful), even the side panels fit perfectly with no moving at all! Top and bottom:
Regular, with no comments.
Overall: WELL DONE Vandy Vape!
2. APPLICATION.
Sign of the times...
Software designed for Swell is ... hmm ... decent. Compared to applications of other manufacturers, it works and look quite good but it also has some issues.
PROS:
* decent general look,
* great responsivity, changes entered on the phone IMMEDIATELY appear on mod,
* quite functional interface,
* convenient firmware update method.
CONS:
* typical problems of BT application, especially when pairing: there are some "network error", during the first attempt to access to the mod (immediately after pairing), the application jumps to the desktop and you have to start it again (tested on Mate20),
* the application does not remember the mod - every time you use the app, you need to put the 4-digit code shown on the mod display.
3. FEATURES.
* power: 188 W
* resistance range: 0.05 - 3 ohm
* modes: VW, Volt, Temp, BYPASS
* battery: 2 x 18650
* weight (with batteries): 206 g
* dimensions: 82 x 55 x 26 mm.
4. VW mode.
Voltage shape at 30 W:
Voltage oscillates a bit at the top, but for us it does not matter, so that it is generally GOOD!
Swell offers power curves, but we can set them ONLY FROM THE APPLICATION LEVEL, not by use of mod. They are called "Set the flavor" option. We have 5 flavors (power curves) to set, but by default they are all flat (without any adjustment) and if we run them from the mod menu without prior setting in the application, we will not get any effect of variable power. This is definitely a disadvantage, but it is also a pros: the use of a large smartphone screen for this makes the Swell one of the most convenient mods.
The curves look like this:
The power regulation is very accurate, with one interval lasting ~ 0.3 s.
The performance:
PERFECT accuracy up to 140 W. A deviation of 2% is actually a measurement error - it's a DNA or Dicodes level. Nice.
The Swell also has Bypass and Volt mode:
WARNING: we get voltage from a SERIAL connection of cells, around 8 V.
5. TC mode (SS316).
Dry wick:
It takes about 0.5 s to voltage drop. So the wick stays white:
Quite good.
6. CONCLUSION.
I found only one disadvantage: no TCR mode. Thats it! Anyway the Swell stays on my shelf.
What I LIKE?
* BRILLIANT ergonomics,
* very accurate electric parameters,
* resin panels,
* color screen ;-)
What I DISLIKE?
* no TCR mode.
