Ive had my kgo since july 30th and yesterday I went to charge it and noticed that the green light on my usb cord wasnt on so I payed it no mind and let it charge. So today I was able to vape up until 1am and the light on the kg started blinking rapidly and then it just shut down???? Okay so I put it back on the charger for another 2hrs and checked the port made sure it was clean put my clearomizer (2.1 LR) back on and stared to vape and I was able to get 4 pulls off of it and then it started to blink again and it shut back off??? Is it the battery did I do something wrong???
