I once did that with a Samsung powerbank I have. Daisy chained the powerbank to charge itself and a phone in sequence.

The only thing that failed afterwards was one of the cables, but suffering a loss was definitely the reason I didn’t attempt to do that again.

It really hadn’t rolled out across the globe yet, so no, it wasn’t even really released before getting pulled.
