One of the quality ergonomic TC box MOD with a highly compact appearance is the Eleaf Invoke. It uses two 18650 cellts and produces a maximum output of 220W. This is one of the plus points apart from the amazing appearance this MOD has. The display has a size of 1.3 inches and there is a centered 510 pin. The Invoke Mod pairs well with the Ellot T. The Ello t has an e liquid capacity of 2 to 4ml. For stronger flavor and larger vape clouds, the HW coils can be used.
