i've just realized that a zna 30 (i guess wotofo one, although not specified in the description) has been already in china warehouse since some weeks ago.
i didn't pay attention because was a bit busy these weeks.
it's sku 20352 (
$73.59 ZNA 30 Style VV/VW mod - Silver), and i guess that it's the wotofo one, as it was the only kind of zna sold in fc till today; so it has the sxa300 chip probably, but you can read a review of this item saying it has the hana chip (dna30) instead of the yihi one.
can anybody ensure it has the yihi sxa300 chip?
edit: also, when i add it to the basket, discount coupons doesn't affect it. maybe discount is not possible with this item, or it might be a bug.
Nikki, have you tested the output voltage step down in the zna robbot? too low wattage message?
