iStick TC40W Key Features

Compact Size, Powerful 40W Output

Despite its compact dimensions of just 36.2 × 22.3 × 77.3mm, the iStick TC40W delivers up to 40W of output power. Its built-in 2600mAh battery provides substantial power capacity while keeping the device portable and easy to carry. The compact body makes it suitable for users who want a capable vape device without the bulk of a larger box mod.

Temperature Control for a More Consistent Experience

Temperature control is the defining feature of the iStick TC40W. In TC mode with Nickel 200 coils, users can adjust the temperature between 100–315°C / 200–600°F to customize their vaping experience. By controlling the heating temperature rather than relying solely on wattage, the device helps prevent dry hits and provides greater control over the overall vape experience.

Less Power and E-Liquid Consumption

The temperature control function is designed not only for temperature adjustment but also for improved efficiency. In TC mode with Nickel 200 coils, the iStick TC40W consumes less battery power and e-liquid compared with VW mode. This makes the temperature control system a practical option for users looking to make more efficient use of both battery capacity and e-liquid.

Clear OLED Display

The built-in OLED screen provides clear access to important vaping information. In VW mode, the display shows battery power, resistance, voltage, and wattage. When using TC mode with Nickel 200 coils, the screen displays battery power, resistance, wattage, and temperature, allowing users to monitor their settings at a glance.

Accurate Resistance Reading

A Modular Design Made to Stand Out

The iStick TC40W provides resistance readings down to two decimal places, allowing for more precise monitoring of the connected atomizer.
With resistance ranges of 0.05–1Ω in TC mode and 0.15–3.5Ω in VW mode, the device supports a range of compatible atomizer configurations.

Durable Stainless Steel Threads

Built for long-term everyday use, it retains stainless steel threads for strong wear resistance. The elastic spring connector also provides high adaptability, helping maintain a secure connection with compatible atomizers. Its standard 510 thread makes the device compatible with a wide range of 510-thread atomizers.

Attached Necklace Hole for Easy Carrying

A specially designed necklace hole is integrated into the top cover of the iStick TC40W, providing an additional carrying option. This small but practical detail makes the compact device easier to carry and access throughout the day.

How to Charge the iStick TC40W

When the remaining battery power falls below 10%, the battery power indicator on the OLED screen will continue flashing to indicate that the device needs to be charged.
Connect it to a power source using the USB cable through the USB port located at the bottom of the device.
Using a 1A wall adapter, a full charge takes approximately 3.5 hours. During charging, the battery indicator continues to flash. Once the battery is fully charged, the screen will turn off.

Recommended Match: iStick TC40W & GS-Tank Atomizer

The GS-Tank Atomizer is the recommended match for the iStick TC40W, particularly for mouth-to-lung users. vCombining the compact 40W iStick TC40W with the GS-Tank Atomizer creates a straightforward setup designed around the temperature control capabilities and 510-thread connection of the device. The combination offers users a practical way to experience the features of this classic iStick vape setup.
