The Yocan UNI 4.0 510 Thread Battery brings a fresh look to the well-known UNI series while keeping the practical features that make this type of battery easy to use. With its futuristic Cyber-inspired design, transparent front and rear panels, and compact 28 × 40 × 75mm body, it feels modern without being difficult to carry. It is available in Black, Silver, Blue, Pink and Purple, giving users a few different looks to choose from.
One of the key features of the Yocan UNI 4.0 is its adjustable 510 cartridge system. The opening can accommodate cartridges from 8–14mm in diameter, while the adjustable height supports cartridges up to 42mm. Two magnetic 510 adapters, including short and long versions, are supplied, making it easier to switch between different cartridge sizes. A small viewing window also lets you check the remaining oil without removing the cartridge.
Inside, the 650mAh rechargeable battery provides up to 4.2V variable voltage, allowing users to adjust the output to suit their preferred vaping style. The USB-C charging port supports 5V/1A charging, while the 10-second preheat function can help warm thicker oil. Safety features include a 15-second cut-off and automatic shutdown after one hour.
The 1.26-inch full-colour TFT display keeps useful information easy to see, including battery level, voltage, puff count and resistance. For shoppers comparing options from a vape online store, the Yocan UNI 4.0 offers a practical combination of adjustable cartridge support, straightforward controls and a compact rechargeable design.
