The popular Aegis One FC vape pen is the first vape pen with a fast charge allowing a full charge in only 15 minutes or less. The Geek Vape One replacement pod has a fixated coil with the available option of 0.8ohm and 1.2ohm, which both create a mouth to lung vape with a discreet amount of vapour. Final Thoughts. The Aegis One is the best MTL device I have tested from GeekVape. If you like the Aegis range, then you should be happy with this kit, the vape quality is superb and it feels really good to use. Score: 9/10 – The quality MTL vape from GeekVape I`ve been waiting Aegis for. There are three power output modes: green for high, blue for medium, and red for low. You can use any power output level regardless of the battery level. The vape kit offers dual activation modes, with both automatic draw activation—where you simply inhale on the mouthpiece to fire—and button-firing.
