Which portable battery chargers work with the iPhone 15 series? I am aware that previously compatible chargers e.g. the Anker 525 Powercore 20000mAh, are less effective chargers due to the reverse charging feature of the iPhone 15.
iPhone 15 Pro Max, iOS 17
Have a look at the Anker Prime. You can program one of the ports to only output a voltage so it won't drain your phone. I've got one and it's a great charger.

The new Anker Nanos work well with the iPhone 15 series. Both the 10K and the 20K versions.
