The charger has since leaked in full in a wireless power consortium (WPC) listing spotted by gizmochina.
The charger appears to have an oblong indentation for the echo buds’ wireless charging case to rest in. The case will have a much different shape than the original echo buds.
The charger also has different charging indicators for the case and the earbuds. There’s also a charging light labelled’- phone,’ which will possibly light up when you place a phone on the pad.
