I’m thinking of buying a PowerCore II 20000, though I would like to be able to charge my MacBook Pro 15" (early 2013) that has a MagSafe 2 socket, along with my other devices.
Would it charge the MacBook? Is it safe?
And, if so, how do I find a cable that is USB on one end, MagSafe 2 on the other? I know Apple doesn’t allow MagSafe products to be made by other brands, but perhaps I can attach different adapters together to achieve this, or find a product that is beyond the reach of Apple’s prohibition?
The charging performance doesn’t need to be spectacular. As long as it charges, and is safe to use that way, I’ll be fine with it. Also, a USB-MagSafe cable could also work, as I’ve got a MagSafe to MagSafe 2 adapter.
