If its allowed I'll link an example case.
Powerbank Output:DC 5V/2.4A, Type C 5V/3A.
Laptop is 2015 MBP 13". Someone told me it's MagSafe 2 power socket won’t charge with anything lower than about 14V.
This to connect powerbank to the MBP.
While charging, the laptop will be turned off.
Will this work?
Is it safe?
If that doesn't work, this seems to work according to seller. Would it be safe to use that?
