My mod keeps turning off when I screw in the tank


I got a KangerTech subox mini kit (doesn’t come with the battery) so I plugged it with the charger and it turned on, then when I screwed the tank in it turned off, is it because I need the battery? Plz help I’m new to this


Yes, a battery (18650) is required to power and operate the device. A USB cord is unable to provide 75Ws of power to the mod.


Thank you so much
