All excellent pieces of advice right there!
Unfortunately, it doesn’t look like VIVA Pro is getting PD or PowerIQ 2.0, and while we can’t entirely rule out one or both of the ports being USB-C based on the information provided, it still seems unlikely.
As far as the inconvenient location of the ports, I know many other reviewers had the same complaint, but it doesn’t look like that’ll be changing anytime soon. I agree with you though, even just a right angle cable would be better than the current solution.
In terms of not being able to find your review, it’s quite possible @AnkerOfficial deleted it. That’s what happened to my post about the VIVA several months before its launch as I had been able to locate the Amazon link with information and pictures. Completely removed; gone. It’s a shame, I know.
Finally, just out of curiosity, were you using the VIVA with iOS or Android?
