I have an Anker MagGo with a flap that makes it double as a stand. I really highly recommend it as a "battery extender" to have in your purse/pocket for convenience. I make sure it's always charged and with me. No cables, and it's still very comfortable to hold your phone when you have it on the phone. That's the only reason I'd go for magsafe on a battery pack, to get that convenience and compactness. I love it for on the go, fast commuting etc.

For larger capacity I have an Anker powerbank with 20,000mAh without MagSafe, with usbc power delivery. It fast charges my iPhone 13 pro max and my M1 iPad Pro and can trickle charge my airpods and other headphones etc. I can fully charge my phone with it multiple times at great speed, and it allows me to comfortably work anywhere with my iPad without worrying about finding an outlet to charge. When choosing this one I prioritized capacity, fast charging and multi device charging.
