Will it ever end? I doubt it. The high wattage wars are just getting ridiculous now
 
Look at the placement of the 510 connector. There will be a massive overhang with any atty and it will look crap.
 
I get half a day running 50w on my sigelei, they going to need to make a better plan for batteries on these high wattage mods.
 
Can anyone make sense of the Ohm's law calculation at 0.04 Ohm given the max amperage and minimum resistance?

The limiting factors are: 35Amax and/or 200Wmax, and/or 7Vmax - IMO misleading advertising as there is no way you can use a 0.04 Ohm resistance coil at 35A or 7V and be within the limiting factor of 200W;

To utilize the full 200W @ 35Amax, the coil resistance can't be lower than:
R = P/I squared
R = 200/ 35 squared
R = 0.16 Ohm [and voltage will be limited to 5.6V]

If we use a coil of 0.04 Ohm and take into account the limiting factor of 35Amax, then we only utilize:
P = I squared x R
P = 35 squared x 0.04
P = 49W

If we use the limiting factor of 7Vmax, and 200Wmax, then we are limited to a coil resistance of:
R = V squared / P
R = 7 squared /200
R = 0.25 Ohm

If we use the limiting factor of 7Vmax, and 35Amax, then we are limited to a coil resistance of (but we are also limited to 200W):
R = V / I
R = 7V / 35A
R = 0.2 Ohm
BUT, one of the factors (voltage or current) will be compromised to stay within 200Wmax limitation:
  • If voltage then:
V = square root P x R
V = square root 200 x 0.2
V = 6.3V
  • If current then:
I = square root P / R
I = square root 200 / 0.2
I = 31.6A
 
@JakesSA I was also worried when I saw all these new devices with the extra low claims.
Maybe @johan can shed some light if nickel plays a factor and the temperature control voltage delivery system.

On the SX Mini that uses a single battery these are there specs

Additional Product Notes
  • In Joule mode, supported resistance range: 0.05 Ohm to 3.0 Ohm
    • Recommended resistance for best performance: 0.065 Ohm
  • Atomizers with Ni200 wire must be paired with the M Class by pressing and holding the up & down adjustment buttons simultaneously
    • Must be performed while both the SXmini and atomizer are cold, and any time the atomizer is changed.

Ni-200 wire is purely for the temperature sensing of the internal circuitry. I will unfortunately not be able to comment without the full detailed data sheet of the SX mini.

PS: High accuracy temperature detectors/sensors (RTD's) function on the principal that a material’s electrical resistance changes with temperature. This positive resistance-temperature relationship holds true within extreme temperature ranges over extended periods of time and linearity. With knowledge of this relationship, an accurate measurement of temperature can be derived from the resistance value of an RTD which are made of inter alia nickel.

Typical RTD (nickel) temperature vs resistance curve

That is awesome!!! first mod I have seen that goes down to 0.04!!! that would be epic!! (if it is on normal kethal and not nickel Wire)
 
Product Description
2015 Snow Wolf 200W Temperature Control box mod.

Specification:

Size: 52mm (2.05 inch) x100mm (3.94 inch) x25mm (0.98 inch)

Weight: 250g (8.82oz)

Material: Stainless Steel

Compatible Battery: 18650×2

Thread Type: 510

Input voltage: 6.0~8.4V;

Output voltage: 0.6~7V;

Output wattage: 5~200W;

Temperature range: 100C~500C;

Atomizer resistance: 0.04~2.5 ohm;

Heating coil material: Common coil and pure nickel coil;

Quiescent current: Less than 200uA;

Maximum current: 35A

Protection function:

Voltage protection: when the battery current is lower than 6.0V, love voltage protection. It shows “Checking battery”;

High voltage protection: when the battery current is higher than 9.0V, high voltage protection. It shows” high voltage”;

High temperature protection: when the temperature of PCBA is too high, temperature protection. It shows” Temperature is too high”;

Short circuit protection: when the atomizer is short circuit, it shows” short circuit”;

Smoking time: when the smoking time is over 10 seconds, it turns off automatically, and stops working.;

Operating instructions:

1. On

When it is on, the system enters into sleeping mode directly, the OLED is off, the system can be wakened when you press any button, OLED shows the main bar, it shows battery capacity, atomizer resistance, output voltage, the temperature of nickel coil when working, and the setting output wattage. When the system which is newly wakened is locked, press any button at this time, the OLED shows LOCKED CLICK 5X, press main button five times within 3S to unlock. If you dont press any button, OLED is off after 30S, you can press any button to waken the system.

2. Battery detection

It works when the battery voltage is over 6.0V, or OLED shows LOW BATTERY, reminds the battery voltage is too low.

3. Resistance detection

The atomizer resistance has to be between 0.04ohm and 2.5ohm. Press the main button, without connecting the atomizer, OLED shows CHECK ATOMIZER, reminds to detect atomizer; when it shorted, OLED shows ATOMIZER SHORT, reminds the atomizer is short circuit; when lower than 0.04 ohm, OLED shows LOW ATOMIZER, reminds the atomizer resistance is too low; higher than 2.5ohm, OLED shows HIGH ATOMIZER, reminds atomizer resistance is too high.

4. Working mode of different atomizers

When it is not nickel coil, it works according to the setting output wattage, OLED shows battery capacity, atomizer resistance, output voltage, output wattage, without showing temperature, only shows temperature symbol. When it is nickel coil, the output is centered by setting temperature, the wattage is adjusted up and down automatically to keep the setting temperature.

5. Wattage and temperature adjustment

When it is unlocked, press the+ button and -button, it adjusts the wattage at first, wattage range is 5.0W~200W. Press the+ button and – button at the same time, it can switch adjusting wattage mode to adjusting temperature mode, after switching, the temperature symbol flicks 10 times, it shows entering into temperature adjustment mode, press the+ button and -button, and adjusts to the expected nickel coil temperature; it can switch to wattage adjustment mode with the same operation.

6. System protection

When smoking time is over 10S, it turns off automatically, OLED shows SMOKING OVERTIME, reminds smoking time is over; the atomizer is removed when smoking, it turns off automatically, OLED shows ATOMIZER REMOVE, reminds atomizer is removed; when the atomizer is short circuit when smoking, it turns off automatically, OLED shows ATOMIZER SHORT, reminds the atomizer is short circuit; when the temperature is over 72 it turns off automatically, OLED shows HIGH TEMP, reminds the temperature is too high; the working voltage is lower than 6.0V, it turns off automatically, OLED shows CHECK BATTERY, reminds the battery capacity is insufficient.

7. Locking down

Press main button for 5 times, it is locked and enters into sleeping mode.

Package Includes:

1x 200w Snow Wolf Mod
1x Gift Box

Awesome explanation @johan
Thanks - that is super informative!!

So what you are saying is that one needs to take into account all the limiting factors of a regulated mod TOGETHER and not in isolation...

Agree, do the calculations for yourself and see if it suits your personal requirements, and don't just fall for the marketing misinformation of power-, current- and voltage capabilities.

I don't think those specifications are misleading per say, just not complete (General problem with temp control mods). The operating ranges are stated, as is the max current. I don't see any claims stating that the device does 200w @ 0.04ohm with a 35A battery, simply that the wattage is adjustable between 5w and 200w and that it accepts coils between 0.04ohm and 2.5ohm.

What I feel is needed with temp regulated mods is different resistances for kanthal and nickel.

From what I understand about temp control... Nickel has low resistance at room temp (0.04ohm lower limit, check), but as it heats the resistance increases, which is how the whole temp regulation bit works, because the mod calculates what the heat of the nickel is based on its starting resistance. The mods don't actually measure the heat of the coil.

Please correct me if I'm wrong.

Lastly, why would people be excited about a mod that "can" run kantal at such low ohms when batteries can't safely handle those resistances? On a vw mod you don't need to super sub-ohm anyway as you can change the wattage...
