Juno Pod System Description The Juno is a creation by the Buffalo-based company Twelve Vapor. It’s a handy, draw-activated, closed system pod mod which lends comparison to the MyJet and Von Erl. It comes equipped with a 380 mAh internal battery, and is easily charged using the micro USB port that is located at its base. Juno uses a salt-based nicotine. This system takes only pre-filled 1.6 ml pods produced by this company and refilling the empty pods is NOT recommended. A tiny LED indicator located 10 mm from the bottom of the device fires green when the battery is between 100 – 16%, yellow between 15 – 6%, and red when you’re at 5% or less.
