Superpower, compact size and comfortable to hold, you want it all? People always thought that strong power should match with large size, SMOK will say NO to that.
The 350W output is the maximum output power in the global with a so much compact size. It is just the GX350 Mod. And GX350 mod max output power can up to 350W when powered by 4 x 18650 batteries or up to 220W when powered by 2 x 18650 batteries. And the Micro-USB port supports firmware upgrade but not for charging.
Please note, batteries sold separately.
