Powerbank for MacBook pro
What specifications should I look out for when looking to purchase a powerbank to charge my MacBook pro during power outages? I need to keep my MacBook alive for 6-8 hours. Thank you.
MacBook Pro 15″, 12.2
Any device you select must support USB power delivery Protocol, and Watts (comparable to what your power adapter provides) at a high enough Voltage typically 20 Volts to charge your computer or keep it running.
An external power supply that provides "USB Power Delivery" (like certain displays) must negotiate over the USB cable using USB Power Delivery Protocol, and can not 'force itself' on your Mac. The Voltage and Current are delivered ONLY after your Mac requests and the charger agrees to supply power under certain controlled conditions. The computer is in control of the entire process.
