Yep that or any 60w dc transformer that accepts usb c outputs. The MacBook Pro charger is that way. I use this

You also need 3A usb c to usb c cord

I’m not sure which iPhone you have, but if it’s new enough then it should have qi charging. The MagSafe duo (or a lookalike) would make an excellent alternative. Then you just need a 60-100W GAN charger with minimum 3 USB(-C) outputs. something like this

That would take it down to max 3 cables.

• 1 for the MagSafe Duo
• 1 for the power bank
• 1 for the iPad/MacBook
• or the first one you linked to
