12 000 mAh MagSafe Power Bank

This 12 000 mAh MagSafe power bank delivers wireless and wired charging in a slim ink-black aluminium shell. It snaps magnetically to iPhone 12 through 17 series handsets for 15 W wireless charging and adds a 20 W USB-C port for a second device. Airline-approved capacity makes it a reliable travel companion for daily commutes or longer trips.

Who it suits and who it does not

iPhone 12 to 17 users who want cable-free magnetic attachment and fast wired backup will benefit most. Buyers with non-magnetic cases or Android phones lacking MagSafe alignment lose the magnetic hold and 15 W wireless speed. Anyone needing more than 12 000 mAh capacity or multiple simultaneous wired ports should look elsewhere.

20 W USB-C output and 15 W wireless

The single specification that decides fit is the combined 20 W USB-C Power Delivery output and 15 W MagSafe wireless output. If your device charges at 15 W wirelessly and 20 W via USB-C this bank matches those rates; higher-speed wired or wireless standards are not supported.

Questions about this item

Does the 20 W USB-C output or the 15 W wireless coil make the aluminium casing warm after hours of use?

The aluminium shell is designed for heat dissipation and an intelligent cooling chip manages temperature during both 20 W wired and 15 W wireless charging, keeping the casing comfortable to hold.

What cable do I need to recharge the power bank itself?

A USB-C cable is required for the input port; one is included in the box so you can recharge the 12000 mAh unit straight away.

Will my iPhone 13 snap securely to the magnetic surface without a MagSafe case?

Upgraded magnets align and hold the iPhone 13 firmly, but a non-magnetic case will prevent magnetic attachment and reduce wireless charging speed.
