light turns red never blue also do I need your usb charger or can I use any usb charger


Answer:
Yocan UNI is an universal portable mod,world's first box mod for all kinds of oil atomizers.
The battery should blink and turn off completely after it is connected and reaches 100% charge.
When that time eventually comes it fully recharges in just 1 hour and supports pass through. So you can vape your Juice while the UNI is charging. At just 3 inches tall, 1.3 inches, wide and about an inch long, the Yocan UNI mod is easily small enough to fit in your palm or pocket for stealthy sessions on the move.
