Cannot use accessory - this accessory uses too much power
Trying to charge my iPhone 15 pro max on my anker portable charger and I get the error message “Cannot use accessory - this accessory uses too much power”.
Has anyone ever seen this? I find it hard to believe that the portable charger uses too much power on the brand new iPhone but not on the iPhone 12 Pro, does that mean my portable charger is worthless with the new iPhone? TIA
iPhone 15 Pro Max
