I plugged in my UNI S for about an hour, but it turns out that it wasn't charging. It won’t charge at all now.
The Yocan UNI S is the latest mod vape solution, it's an item of UNI series.
As we know, the Yocan UNI S feature type-c charge port, and built-in a 400mAh battery.
USB type-c battery charger included. Battery indicator will glow when
it is charging. In around one hour the battery will be fully charged. Once
fully charged, the indicator flashes 8 times and then shuts off.

So, I think your device is fully charged. Please try to 5 click the fire button to turn it on.
Any further question, please let me know.
