Pioneering Fast Charging Technology for E-Cigarettes

The development of e-cigarettes has led to a market trend where technology is increasingly leaning towards small smoke products, including nicotine salts, N-generation ceramic atomization technology, and multiple leak-proof packaging…

Nevertheless, the core technology of e-cigarettes remains unchanged; beyond “atomization” and “e-liquid”, the most critical component is the “battery”.

The battery not only determines the performance of e-cigarette products but is also the most significant factor affecting user experience. Regardless of how advanced the atomization technology or e-liquid is, without a stable power supply, achieving the desired effect is challenging.

Entering the year 9012, the proliferation of digital and electronic products has led consumers to suffer from “battery anxiety”. The battery capacity of phones, players, headphones, and power banks is not only increasing but “fast charging” has also become a standard feature. After all, no matter how large the battery, it will eventually run out; it is much more convenient to “charge for 5 minutes and use for a whole day”.

This is vividly reflected in smartphones. In the early days of replaceable batteries, most people would prepare more than one spare battery to ensure their phones were “always powered on” and could revive at any time.

With the development of technology and the increasing functionality, the integration of components within phones has grown, and battery capacity has increased. Due to safety and other considerations, replaceable batteries have exited the stage of smartphone history.

This change has been quite inconvenient for consumers suffering from “battery anxiety”. Previously, when the battery was dead, one could simply replace it with a new one; now, they must rely on power banks and wall sockets.

This is similar to e-cigarette users, especially those who enjoy large vapor production. Early e-cigarettes mostly used replaceable 18650 lithium batteries. When the battery ran out, users could seamlessly switch to a fully charged battery, and charging the battery separately would not affect normal use.

In those days, if you didn’t have a dozen lithium batteries, how could you claim to be using e-cigarettes?

However, as time has changed, the drawbacks of 18650 lithium batteries have become increasingly pronounced.

Firstly, these steel-cased lithium batteries are essentially industrial “semi-finished products”. They are not as reliable in insulation and safety as consumer products, posing significant safety risks.

Secondly, there are many differences in brand, capacity, and discharge parameters of 18650 lithium batteries, making it difficult for ordinary users to distinguish between them.

Moreover, sellers in the retail market vary in quality; expensive purchases may very likely lead to counterfeit or substandard batteries, creating larger safety risks for e-cigarette use.

Thirdly, from the consumer experience perspective, replaceable lithium batteries also have many issues. Besides requiring users to understand relevant battery knowledge, they must also purchase a separate charger.

Many novices, after buying their first e-cigarette set, find they are unable to use it because they do not realize that they need to install a lithium battery in the device.

As a result, e-cigarettes with built-in batteries are becoming increasingly common, especially for products like small vapor devices, which can be used immediately without worrying about what type of battery to install or whether the battery parameters and output are compatible. When the battery runs out, users can simply plug it into a USB for charging, which is very convenient.

Despite the many advantages of built-in batteries, the most “fatal” disadvantage is that when the battery is depleted, it can only be charged and cannot be replaced.

Even if we calculate based on a capacity of 5000mAh, if charged at 2A, it theoretically takes nearly 4 hours to fully charge. Although in actual use, it may only take 2-3 hours, it means users cannot use their device for several hours. If they discover the battery is dead just before going out, they face a tough choice: wait for the e-cigarette to charge or be punctual for an appointment.

Moreover, 5000mAh is not considered high for high-power devices.

For users who enjoy large vapor production, only “fast charging” is the way forward.

With a little effort to change the coil and cotton, the device can be fully charged, and this wish has now been realized!

The revolutionary fast charging chip IFV960 developed by Sigare has successfully been applied in the “SNOWWOLF” ZEPHYR 200W device, supporting 45W fast charging and increasing charging speed by at least 3 times!

The “Snow Wolf” system has greatly optimized charging speed, allowing the 5000mAh capacity to be fully charged in 35 minutes, which is more than 3 times the normal charging speed.

In Sigare’s product philosophy, there is no compromise on charging, a highly impactful aspect of user experience. They chose to tackle this pain point themselves rather than passing the problem onto users, providing convenience to them.

“Any new generation product from Sigare must have the charging time strictly limited to within 40 minutes!” This is a “mandatory requirement” set by Sigare for product development, ensuring that all types of e-cigarette products meet this standard.

The IFV960 chip equipped in the ZEPHYR 200W device not only increases charging speed by 3 times but also controls the output through an intelligent chip. It optimizes the flavor of e-liquid atomization, providing a rapid “ignition” in 0.0008 seconds, allowing for high explosiveness even on the first puff, improving the drop in vapor and flavor caused by cold starts.

The chip also features ten protections, enhancing user experience while providing greater safety assurance.

Unlike previous ordinary color screens, the Zephyr features a newly designed 2.0-inch large screen, allowing users to intuitively view detailed parameters and information. The touch area below the screen replaces traditional adjustment buttons, making the device more integrated.

The ZEPHYR retains the traditional style of Snow Wolf, with the logo on the back of the device. However, unlike before, the ZEPHYR features a breathing effect made of LEDs, making it visually more stunning.

Conclusion: The fast charging technology of ZEPHYR addresses the pain point of battery life for high-power output devices, balancing battery safety and performance at a new level, and laying the foundation for Sigare’s new generation of products. In the future, Sigare will launch various new products based on the IFV series chips, enhancing user experience while providing greater safety assurance.

Currently, ZEPHYR is only sold in overseas markets such as Europe and the United States. Domestic users cannot yet experience the powerful performance of IFV. Coupled with the “internet ban” on e-cigarettes, users can only experience Sigare’s new products in physical stores, and there are no plans for domestic market launch in the short term, which is a significant regret for domestic vapers.
