Snap-On Charging Without Fumbles - Thanks to Ultra-Strong Magnets

Ultra-strong magnets align the battery precisely with compatible iPhone models, reducing the common misalignment that interrupts wireless charging. Alignment is designed so the battery sits flush, keeping contact steady during calls and selfies.

Secure attachment allows single-handed use while charging, so taking photos and handling calls remains straightforward. Reliable alignment reduces failed charge attempts and mid-charge disconnections.

MiniCell technology achieves identical charging performance with fewer internal components, producing a smaller and lighter power bank. Component miniaturisation reduces bulk while retaining effective energy storage and delivery.

Slim dimensions make it easy to carry in a pocket or small bag, ideal for commuters and day trippers who need an emergency top-up. The compact size keeps everyday carry simple and unobtrusive.
