Batteries come with many voltage settings. So before you panic that it isn’t working fine, check the user manual carefully. You need to press the button 5 times if you want to turn it on or off. Furthermore, if you wish to change the device voltage settings, press it 3 times. If it still doesn’t work, try plugging in the USB Charger. If there are still issues with Vape Cart or Battery, you can contact our customer service team, and they will guide you correctly.
