Basically it's important to understand that this is not really a battery pack. It's a battery extender. I have an Apple iPhone 12 Pro Max and this extender will only charge the iPhone 30%. In other words if my iPhone's battery is 50% charged the extender will only charge it to 80%.
The magsafe battery pack keeps my battery a decent amount up, and isn't difficult to use. Definitely not as great for charging as a corded battery pack, but it's a lot more convenient to just slip into a bag without the wires. Nice that I can use it on my airpods too. I find the lightning charging convenient since I charge everything else I have with it too.
This product charges your phone when you are away from home and your regular chargers are not available. It gives me a feeling of security that I can always communicate with someone if I need to. It does help to go on the Apple support site to be sure you set it up, charge it, and use it correctly. I have given two as gifts.
