The Yocan Lux is a sleek and stylish vape pen. The open cartridge setting allows you to use a wide range of 510 carts since it will sit atop the battery and there's nothing to get in the way. Click the button 5 times to turn on/off, click twice to use the preheat feature and twist the tip to adjust the temperature. After 15 seconds of use, it will stop to preserve battery life. The alloy body has a lightweight feel, but it super durable. Equipped with a 400mAh battery, you can easily charge it with a USB-C. Change temperatures between 1.8-4.2 volts to customize your session.
