Last year September I purchased two of these power banks from Ebay
I gave one to my friend and took one for myself. Just last week I saw my friend and we both had our power banks and I put them side by side and realised I had the V1 and he had V2 even though we purchased from the same listing claiming it was V2, same order. I'll upload a picture soon.
Now it's been over 9 months since the order and I've probably since thrown the box out for my powerbank. Is it even worth raising this issue with SS?
no
tldr; no :)
