I got this 5000mAh wireless, MagSafe-compatible battery when the iPhone 12 mini was (briefly) my primary phone. The battery life on the phone was horrendous so I used this quite often to get by. It served its purpose; it's very small and light. Even with my iPhone 15 Pro I always bring this battery on trips and don't need to worry about having a cable with me. Anker has since made some newer versions, I'm linking to the latest one below.
