^^^ Unless your wife chain vapes at 8+ watts or can't live with an 800 mAh battery with pass-through capability that allows simultaneous vaping and charging I think your wife will be delighted with the iTaste VV 3.0. Despite the name it does, indeed have VW as well as VV. I have three and all have performed perfectly all the time.
If you don't mind waiting a week or two fast tech has the full kit iTaste VV 3.0s with the iClear 16's for $39.54.

Should gave more info about her, she has a Ego 650 right now and shes never ran it down, Only time it was charged Aside from when first got it, in the 2 weeks shes owned it was from me vaping it cause I wanted to get the battery some usage . She doesn't vape very much at all, My 1000mah is blue right now cause its on 20% from today ha ha..
Not sure why she want's it I guess cause it is VV and I am about to have a Vamo so she wants one with VV also .
I think it be better then her Ego 650, bigger battery and a pass through, My 1000 is pass through and I love that. I Think I would have gotten the Itaste instead of the vamo if I had known about them, I see a guy in a video using one, and looked them up today.
Read a couple people saying they dropped there Itaste and now the buttons are messed up and or this or that, but you should try hard not to drop these, I mean they have battery's in them and No battery should be dropped.
like said we have a few CE4's she has a couple of Kanger T2's and now has my mini pro tank so shes good with tanks
