In case of an emergency, I'd like to use my solar powerbank to charge my Macbook 2015 13". It outputs 2.1A 5V, and I learned that the MBP can be charged with that, but I don't know if that's actually true (is it?). It would take about 12 hours to fully charge it I think, which is okay
Now next problem is finding a USB to MagSafe 2 Adapter. Any ideas?
What if I use USB to USB-C, and USB-C to Magsafe 2 adapters? :) Those are readily available on the market.
Edit. I've found this which simplifies things.
Do you think this is safe? (charging mbp with 11W)
