Ultra-slim magnetic power bank

The Aobbow ST-338 is a 5000mAh lithium-ion power bank measuring .4 inch thin and weighing .35 lb. It snaps magnetically onto compatible iPhone 12 through 17 models and AirPods wireless charging cases for cable-free charging. A built-in LED display shows the exact remaining percentage. The unit is new and finished in Titanium Gray.

5000mAh capacity and everyday headroom

The 5000mAh cell can fully recharge an iPhone 17 once or provide up to 70% power for a Samsung Galaxy S26. Wireless output delivers convenient cable-free top-ups while you text, scroll or take photos. For a faster boost the USB-C port supplies up to 15W wired charging, taking an iPhone 15 from 0% to around 40% in 30 minutes. Heavy users needing multiple full phone cycles will find the capacity runs out after a single day.

USB-C and MagSafe interface limits

Both input and output run through a single USB-C connector rated at 5 V and 3 A, capping wired throughput at 15W. Wireless charging relies on MagSafe alignment, so it works only with iPhone 12, 13, 14, 15, 16 and 17 series plus AirPods wireless cases; Android devices without magnetic alignment cannot use the snap-on feature. The 5000mAh internal cell also limits total energy delivery before the bank itself needs recharging.

Questions about this item

Will the .4 inch thickness and 5000mAh capacity work with my iPhone 12 case?

The power bank snaps magnetically to MagSafe-compatible iPhone 12/13/14/15/16/17 models and is .4 inch thin, so it fits most standard MagSafe cases without blocking the camera.

How do I confirm the 15W fast charging is active after I attach it?

The LED digital display shows the exact remaining battery percentage and will reflect the charge rate; a rapid drop in the power bank's percentage while the phone rises confirms 15W output.

Does the box include a USB-C cable for the 3A input port or only the magnetic pad?

The package contains the ST-338 power bank itself; a USB-C to USB-C cable for 3A recharging is not included and must be purchased separately.
