Eleaf iStick TC40W

Cheap solution for the start of TC adventure.

1. The FINISH.

Plastic fantastic :-) Typicall at this price (about 30$), however everything is well-fitted with no looses and mod lies well in the hand. And thanks to the plastic finish it is very light. The 510 head is quite decent:

with plus pin on the spring - so each tested atomizer worked with no any problems.
Next to the head we have attached necklace hole. On the bottom:

 

we have only microUSB socket.

The display:

is typicall DNA20-style, with the battery, resistance, voltage and power indication. In TC mode the themperture is shown instead of wattage.


2. FEATURES.

* Output Power: 40W
* Coil Resistance:
- 0.05 - 1.0 ohm in TC mode
- 0.15 - 3.5 ohm in VW mode
* Temperature control: 200 - 600F (100-315 *C)
* Built-in battery capacity: 2600 mAh
* pass-through feature,
* dimensions: 22x36x77 mm.

For the beginners is enough...
The menu is very simple, with additional middle button for mode selection.

NOTE - iStick40 has no wattage regulation in TC mode. Why? Because in this mode the temparature has the PRIORITY - independently of preset wattage mod primarily check the  temperature, and control the voltage so as to ensure that the temp. limit is not undershot. Between us most other TC mods work in a similar way - yes, we can set e.g. 140W in Snow Wolf but so what if mod after half second will have to drastically pull off the power to maintain the temperature?
So do not worry too much about it because generally it works, and the cloud is regulated by changing the temperature limit.


3. VOLTAGE SHAPE.

Measurements were done in my typical test set-up with 1 ohm microcoil on MutationX atomizer and Tektronix TPS2012 oscilloscope.

It is quite well. Although there are some oscillations it is unnoticeable during regular wape.


4. EFFICIENCY.

Having the setup with 1 ohm coil we can also check if we get what we set. Below I compared:
* theoretical voltage what should be on the coil for a given power (calculated according to the P=U^2/R formula),
* real voltage MEASURED on the atomizer pins by use of multimeter.

No comment... Everything is perfect, mod as usual adds a little more voltage than is needed ;-).


5. TEMPERATURE CONTROL

Is VERY WELL - described here. 


6. DRAWBACKS

1. The 510 head is designed so as to leave a gap below the atomizer. In my opinion it is less than half a millimeter and it is hard to see, however it is... One theory is that they did it to avoid scratching the beautifully chromed surface during mounting the atomizer.

2. "Lightness" of the mod. So, when using large and heavy atomizers center of gravity is very high and mod easily falls. 


7. SUMMARY
What can be in case of mod with reasonable power, sub-ohm handling and VERY GOOD temperature control for 30$?
For the start of adventure with TC buy without hesitation!

What I LIKED?
* VERY GOOD temperature control,
* ergonomics,
* 0.05 ohm.

What I DISLIKED?
* built-in battery,
* a bit too plastic.
