The Efest Lush Q8 Intelligent Battery Charger is able to charge up to 8 batteries simultaneously. Additionally, it can charge your batteries in speeds up to 2A. Depending on how many batteries you're charging at once will determine the speed since it features an automatic selective charging mode.
When you're using all 8 slots in the Efest Lush Q8, it'll charge your vape batteries at 0.5A.
