MagSafe 12000mAh power bank

This 12000mAh power bank uses MagSafe alignment to charge compatible iPhone 12 to 17 models wirelessly at 15W. A 20W USB-C port can power a second device at the same time. The aluminium alloy shell helps dissipate heat during use. It is designed for people who want cable-free charging with magnetic attachment.

Check device and case compatibility

Magnetic alignment and full wireless speed only work with iPhone 12 through 17 series that support MagSafe. Other phones will charge wirelessly but without magnetic hold or maximum speed. Non-magnetic cases prevent the magnets from connecting, so an Apple official or certified MagSafe case is required. The power bank should be charged once before first use.

Included USB-C cable and safety features

The box supplies a USB-C cable used for both recharging the power bank and for wired 20W output to a second device. Built-in protection guards against overcharging, overheating, over-voltage, over-current and short circuits. An intelligent cooling chip works with the alloy casing to maintain battery health during extended charging sessions.
