Eleaf iStick TC40W Battery Only

iStick TC40W

iStick series battery adopts a newly added temperature control. It brings out a unique vaping experience without dry hits by adjusting temperature setting. Despite the small size, it can reach 40W with one large, built-in 2600mAh battery. Moreover, all stainless steel threads and elastic spring connector endow it with strong wear resistance. With temperature control function, less power and e-liquid consumption will also be a plus.

iStick TC40W features:

The Eleaf iStick TC40W is a superior device that includes innovative temperature control technology delivering a unique vaping experience. The 2600mAh battery has two modes; TC (temperature control) mode and VW (variable wattage) mode. When in TC (temperature control) mode, the iStick TC40W supports a resistance of 0.05-1ohms and in VW (variable wattage) mode with resistance 0.15-3.5ohms.

The VW vape mode has a maximum output of 40W. Applying the TC mode ensures the iStick TC40W quickly reaches the maximum temperature selected and then automatically regulates itself to stop exceeding this temperature. The variable temperature function dramatically reduces the risk of prematurely burnt atomiser heads and dry hits. The TC 40W requires a Nickel coil fitted tank to exploit the temperature control functionality and has a temperature range of 100-315°C (200-600F). Utilising temperature control means you will benefit from reduced power, e-liquid consumption, enhanced vapour production at lower settings and reduced vulnerability to coil overheating resulting in longer atomiser life.

The iStick TC40W boasts a range of safety features including short circuit, low voltage and temperature protection. The five click on/off function prevents accidental activation, and the inclusion of an OLED screen allows you to quickly view all your vaping information including battery power remaining, resistance, wattage and temperature set. With high durability and outstanding performance, the TC40W e-cigarette battery is an impressive device.

  • Safety features: 5 clicks on/off function, short atomiser protection, low voltage protection, temperature protection and temperature alert.



  • 1. Temperature control function. By adjusting the temperature in TC mode(Nickel 200), you can enjoy a different vaping experience at different temperature settings
  • Less power and e-liquid consumption. With temperature control function, it will consume much less battery power and e-liquid in TC mode(Nickel 200) than in VW mode.
  • Clear OLED display.  In typical VW mode, the OLED screen displays battery power, resistance, voltage and wattage.  An accurate reading of resistance
  • In iStick 40W TC, coil resistance is more accurate with the number down to the second decimal point.
  • Large output and power capacity. Despite the small size, it can reach 40W output with 2600mAh power capacity.
  • Stainless steel threads and spring connector. It retains stainless steel threads for strong wear resistance and elastic spring connector for high adaptability.
