Not really. It’s a phone and watch charger. Neither of them use USB-C connectors. Only one of the devices typically need a charge “boost”, which is the phone. The same cable to charge the phone by itself should be the same one that powers the Duo.
Of course we want the phone to be USB-C as well, but I think we’re close to finding out.
The 30-pin connector stayed for 9 years before the introduction of Lightning.
Lightning started in 2012.... conveniently 9 years after 2012 would be any phone released in 2021.
The only unknown is whether they pivot to USB-C or go portless.
