How Is the TESLACIGS INVADER 4 Vape Device?

In 2016, when high-power devices began to emerge, TESLACIGS released the INVADER III, a stable voltage high-power device that became a hit due to its industrial design, extremely simple operation, and explosive ignition experience. A year later, the INVADER series introduced the INVADER 2/3, which was not a continuation of the III. Today, we share the INVADER IV, which is two years apart from the previous generation III.

Under the halo of the popular INVADER III, the subsequent models naturally received more attention, and the packaging of the INVADER IV clearly reflects TESLACIGS's effort to create a new image for this model. The official website offers this device in black, blue, red, orange, and silver, all featuring an aluminum alloy body with an anodized surface finish.

Compared to the 18650 battery standard used in high-power devices in 2016, e-cigarette devices have evolved over the past two years to embrace the more powerful 21700 and 20700 batteries. A significant difference of the INVADER IV compared to its predecessor is that it supports three types of batteries: 18650, 20700, and 21700.

The package only includes the device, a manual, and a USB cable. However, other sources indicate that the INVADER IV is available in both single and kit retail versions, and this article refers to the single version. The device dimensions are: 92x60x28mm

Material: Aluminum alloy body / anodized surface

Battery support: 18650 / 20700 / 21700

Weight: 143g

Voltage levels: 1 / 2 / 3 / 4 / 5 (five levels available)

Output voltage: 3-8V

Maximum power: 280W

Minimum resistance: 0.08 ohms

Charging parameters: 5V / 1.5A

Information display: LED lights in blue / green / red

TESLACIGS has replaced the zinc alloy material used in the INVADER III with the currently popular aluminum alloy, resulting in a weight reduction to 143g and an outstanding surface texture. The USB interface provides a direct charging function of 5V / 1.5A, and during charging, the LED light bar will indicate the real-time battery level with blue (61-100%), green (31-60%), and red (0-30%).

The compatibility with 21700 batteries clearly means that this device is larger than the INVADER III, which used 18650 batteries. However, in the era of small pods in 2018, the positioning of high-output devices has shown indifference to the "size war." After all, users who use e-cigarettes purely to replace smoking do not consider how portable a dual 18650 device is compared to a small pod.

The white long LED is the only signal feedback part of the device, with blue, green, and red colors and flashing frequencies indicating various information (refer to the manual for details). The signature voltage adjustment dial of the INVADER series makes it convenient for users, who do not need to worry about the "W" value but can simply adjust the level according to their heating speed needs.

The device features linear grooves and heat dissipation holes as its main external embellishments, giving it a more refined feel compared to the INVADER III. Evaluating the device's seams, assembly, ignition button feel, and dial damping, the INVADER IV shows significant improvements in craftsmanship, and this gap is not small.
The manufacturer provides two 18650 battery conversion sleeves, allowing users without 21700 or 20700 batteries to use standard 18650 batteries in the INVADER IV. However, due to battery characteristics, this may affect the final performance of the device. The device has a single ignition button and supports the five-click on/off command.

For high-output vaping, the consumption rate of e-liquid and battery power is proportional to the amount of vapor produced. While greater power may not be the main highlight of the INVADER IV, the difference in battery life between the 21700 and 18650 batteries is the core of its evolution, and it is undeniable that it is more powerful.

Compared to the INVADER III, which required fingernails to adjust the dial, the INVADER IV has optimized it into a "protruding" form, allowing users to easily adjust the output power by rotating through five levels. This stable voltage output method is simpler and more intuitive than power adjustment. Although the output power varies depending on the matching atomizer resistance, the underlying output voltage remains the same.

So, what are the advantages of the INVADER IV compared to its predecessor?

1. Battery compatibility enhances battery life in 21700 mode;

2. Direct USB charging is more convenient than the previous model, which did not support direct charging;

3. Anodized aluminum material makes it lighter and more comfortable to hold;

4. The device thickness perfectly accommodates larger diameter atomizers (the previous model only perfectly matched 22MM);

5. Dial adjustment is easier, and LED feedback is clearer.

With the improvement of product research and development capabilities and changes in market demand, the development of devices needs to provide a more practical, better, and easier user experience while also meeting the demands of market development. In the 2018 explosion of nicotine salts and small pods, players following the big cloud trend no longer demand perfection from high-output devices. Under the premise of meeting performance requirements, compromising on size is the first step of sacrifice...

The INVADER IV is such a product. It retains all the advantages of the INVADER III, such as ignition style and simple operation, which have been inherited. In terms of performance, it achieves more convincing results through battery replacement and compatibility, and in craftsmanship, it shows real upgrades. These are the attitudes that a subsequent product should have, and all of these can be found in the INVADER IV...
