I am a two month convert to vaping and have purchased the itaste mvp last week which has worked great.....until the third charge. Anyone know if there is something special i need to do as far as reseting or pushing a series of buttons a certain way to get it to charge? When i plug in the charger to the small port, the push button light quickly goes through all three colors then rests on the red light. It will stay on that red light and not charge. Left it alone twice for hours. I even tried it on my cell phone charger with no luck. The two times prior that it did charge, the light was green during charge if i remembrr correctly and the light was off when fully charged. Unfortunately there are no instruction included with this device from the manufacturer. Any help would be greatly appreciated.
