Hi BustedBanjo, I believe the charger attached to the side of the phone is a Toprig NP-F Battery Charger which is available from AliExpress, however I believe the MagSafe item on the back of the phone is not a charger, but is in fact a cooling fan being powered by the usb-c output on the Toprig charger and an NP-F battery. There are several MagSafe phone fans available on Amazon.
With everything the phone is doing, it is likely to be generating quite a bit of heat, hence the necessity of using a fan.
