Charging with MagSafe cable/puck thingy but using ANY OTHER battery pack/bank! (Let's try again)
Oh my days! I've either lost the ability to do what should be a crazy simple web search or Apple's SEO is so freakin' Jedi even Google cant give me anywhere near the answer I need. I just want to know if I can plug my MagSafe cable/silver-puck-thingy into a 3rd Party battery bank and pull a charge? What spec's does the battery bank need to charge my phone that way? I'm assuming at least USB-C output but what about the wattage and electrical gubbins? Essentially I neeeeed to charge my phone via the MagSafe cable and a separate battery bank. I cant use the Apple MagSafe sticky-onto the phone itself battery pack so don't try to sell me. Literally. Don't send me a link to the: https://www.apple.com/shop/product/MJWY3AM/A/magsafe-battery-pack It will not work for my use case!
It's not hard. Your MagSafe cable/puck-thing (just to help ya: https://www.apple.com/shop/product/MHXH3AM/A/magsafe-charger) connected to iPhone 12 Pro requires X to charge? I go find a battery pack that can deliver X. Job done.
