Thanks, very thorough and bottom line approach (explaining max. current flow of probably 1.5A versus 2.5A on two batches, when powered off)! Anyway, hoping that L5 can manage full load of up to 5A Type-C SuperCharge cable (just to be on safe side) is not in question here. For general orientation I think we might use following best values (phone related) for same charger USB-A output (to USB-C): 4.5V/5A, 5V/4.5A, 12V/2.5A, 20V=1.5A and for USB Type-C output: 5V/3A, 12V/2.5A, 15V/2A, 20V/1.5V Max., as both types of outputs are usually built within the very same modern charger, when 1+1 version. Question for myself is if we are comparing cheap 5V/1.5A charger (2?%/60min.) vs original Dogwood 12V/2.5A (6?%/60min.) charger (perhaps 12V only)? All I need are clear L5 charger specifications / recommended ones and not yet another charger.
I don’t know everything, but I do know that finding Type-C PD2.0 60W Flash Charge Data Cable that is capable of transmitting 20V/3A on his own is not a problem any more (even though not an accustomed purchase).
