How Long Does One Charge Last on the YOOZ Gen 2?
The YOOZ Gen 2 has several noticeable improvements compared to the YOOZ Gen 1, but the only way to distinguish them is through the color of the device and the Type-C charging port at the bottom.

Today, we will only discuss the optimizations and upgrades in terms of battery life and device lifespan.
In terms of cartridge slot, the YOOZ Gen 2 has optimized three structural aspects, significantly extending the lifespan of the device:
First, the liquid storage tank has been enlarged. The YOOZ Gen 1 had a relatively small liquid storage tank that was inconvenient to clean, which reduced the lifespan of the printed circuit board. The YOOZ Gen 2 has changed the sealing silicone structure to enlarge the liquid storage tank, extending the lifespan of the printed circuit board;
Second, the mouthpiece has a leak-proof structure. According to the YOOZ brand, during testing, the mouthpiece remained stationary for 24 hours after liquid was dripped, with no e-liquid leakage. Even under a 3Kpa negative pressure, there was no leakage;
Third, the sealing effect of the silicone has been improved. The battery tube slot of the YOOZ Gen 1 was sharp-edged, which could damage the sealing ring when inserting the battery holder, leading to condensation liquid entering the mainboard. The battery tube slot of the YOOZ Gen 2 has been changed to a 45°C angle, ensuring the integrity of the sealing ring when inserting the battery holder.
The air intake holes have also been optimized, changing from 1.15mm in the YOOZ Gen 1 to 0.7mm now, with the suction resistance adjusted to control between 600Pa-900Pa (flow rate 17.5 ML/S), providing a better puffing experience.
The YOOZ Gen 2 adopts the now popular Type-C charging port, solving the user’s frustration of never being able to plug it in correctly.
Additionally, YOOZ has stated that the USB connector housing is DIP-shaped, and the soldering method between the PCB board is plug-in soldering, which is sturdy and has a long lifespan.
The breathing light has also been upgraded. The breathing light of the YOOZ Gen 1 was monochrome, while the YOOZ Gen 2 has a three-color breathing light: when the battery is <30%, it shows red; when the battery is 30%-60%, it shows green; when the battery is >60%, it shows white. The light gradually brightens over 1.6 seconds during use and gradually dims over 2 seconds after stopping use.
This is very useful in actual use, as it effectively helps users grasp battery information and prepare for charging in advance.
Finally, how long does one charge last on the YOOZ Gen 2? The YOOZ Gen 2 is equipped with a 350mAh battery, the same as the YOOZ Gen 1, and in a fully charged state, it can generally ensure a day of use (I have tested it to last about 1.5-2 days); the official charging time is 40 minutes, and it generally takes about 30-40 minutes to fully charge from an empty state. (Note: The battery life of the device is more related to individual puffing frequency.)
I bought both the YOOZ device and cartridges here, with discounted prices and guaranteed authenticity, and I recommend it to everyone today.
