Nice little gadget.tried today took not muck to charge the power bank. And no problem with my mvp or Vv itaste. Not tried with the big boy charger yet ( 18650 efest luc 2 ) .
Has usb output, 6 v or 12 v . 7 w max output. Powerbank can be charge by usb as well . Not really vape related but i think is cool .
