I am looking for a power bank that is able to charge both my iPhone and my MacBook. How many watts would the power bank need to output to be able to charge the 14 inch MacBook Pro?
Any help is appreciated :)
It's not that simple. You don't just assert a voltage at a modern USB-C Mac and expect it to charge.
Macs use USB-C Power Delivery protocol to negotiate with the power adapter. The two negotiate a Voltage and current that will work, then the Mac commands the power adapter to supply it.
The MAC is in control of the entire charging process.
Ok, well what would a power bank need to have to be able to charge a MacBook.
USB Power Delivery Protocol -AND-
the ability to supply about 67Watts (over 2.5 Amps at 28 Volts DC) for regular charging.
.
What is the minimum wattage output required for a 14 inch MacBook Pro to charge from a power bank?
