I've had the Anker 622 for a while now. It's about the same size as the official apple magsafe pack but it has a stand and that's mainly why I use it. It's nice to be able to prop the phone up when I'm washing dishes or whatever. Bonus is it's charging as well. Not super big, will take the 13 and 14 pro max up about 58-65% maybe. Handy when you need it, stays on well, and half the price of others at the time.

Same boat I'm in right now. Says that they are outside of the case, with me in my house, and it's been that way since Dec 6. I've pretty much wrote them off at this point.
