The Aneng LT002 power input plug is a female USB micro-B, the “charging line” looks to be some cheap no data or bridged data lines USB A to USB micro-B cable.
This newer version seems to be a refinement of the iron which Dave reviewed, thus it uses the same tips with integrated heating element (tips which can be bought for less than $2 a pop in AliExpress, shipping included).
It will be interesting to see how does it manages to adjust the tip's temperature once some technically inclined fellow dissects it and takes a look. Maybe they managed to fit and use some thermistor inside close to the tip?

5 V and 1.6 A means the resistive element is 3.125 Ω. To crank up the tip's power some extra voltage is all it is required (P = V² / R), exactly 6.25 V to reach 12.5 W. But the practicity of this will depend on the way the iron adjusts the tip's temperature, and its resistance to oxidation. The tip reachs quite high temperature in the first version of this iron.
