iPhone 12 to 17 users wanting cable-free top-ups

This charger suits owners of iPhone 12, 13, 14, 15, 16 or 17 models who want a slim battery that snaps on and stays put while the phone is used. It also works with AirPods wireless cases and Android phones that support magnetic wireless charging or MagSafe cases. Buyers who need more than roughly .7 to .9 of a full phone charge per cycle, or who must charge multiple devices at once, should look at a higher-capacity bank.

5000mAh capacity

The 5000mAh rating determines how much backup power is available. In practice this provides about .7 to .9 of a full charge for many iPhone models after conversion losses. If your daily routine demands a full recharge or more, this capacity will fall short.
