So you said that you are looking for more power than the Kanger 60W Squonkbox, so I am assuming that you want to go higher than 60W.
Based on this yes I think the Kanger 160w would be the way to go. If you are looking for something in a different shape, go with the Lost Vape Halycon.
The Kanger is cheaper and I have heard the RDA is not the best, but it is a dual replaceable battery mod.
The Lost Vape Halycon has a DNA Board, has more power (200w vs 160w) but you are stuck with a internal lipo battery.
