The 4 Nine style mechanical mod is one of the smallest 18650 mechanical mods on the market.  The 510 connector uses a direct connection to the battery (your atomizer touches the battery directly, hybrid)  so voltage loss isn't an issue as it directly contacts the battery.  This Mechanical device is only recommended for advanced users - please do not store the device with a battery installed.  The battery tubes included can also be changed to fit other 18xxx sereis batteries.  We recommend the use of button top batteries versus flush top, and we ask that you do not attach 510 connections that are completely flush as they may short out.

Low price

Multiple sizes in one

What's included?

4 Nine Style tube mod and sizing rings
