Hey all, I love my iTaste but I kill this thing in about half a day. I use it on passthrough too but I have a feeling I will rifle through this battery's life span pretty quickly. I work from home and I chain vape all day long. Is there a battery you would recommend that is VV/VW that would last me all day long? I really do like VW/VV. Should I just buy another iTaste, or maybe the SVD? Is there something else out there that is better (lasts longer)? Thanks all!
