Is that a certified lightning connector? I'd be curious about that process or, if it isn't, the decision to forgo it and whether or not you did any user testing around it.
We have some info on the connector here: https://cobattery.com/connector
Apple doesn't actually let you buy a chip that will allow for the right angle connector that we have. So we decided to design our own. It was a pretty time intensive process and we had to search for a while for a good factory. But we are happy with the way it turned out.
