MagSafe Power Bank for iPhone 12–17

The Wowuwoai W20 is a 10000mAh lithium-polymer power bank built for MagSafe-compatible iPhones from the 12 series through the 17 series. It attaches magnetically with an 11N hold so the phone stays in place while charging wirelessly. A fold-out kickstand props the phone up for hands-free viewing. The unit also supplies power to other devices through its USB-C port.

Snap-On Mounting and USB-C Fallback

Alignment is automatic: bring the phone near the bank and the magnets pull it into the correct coil position. Wireless output reaches 15W when the handset supports it. For non-MagSafe phones or thicker cases, plug a cable into the USB-C port for 20W PD or QC 3.0 charging. The bank itself recharges through the same USB-C input. A five-LED row shows remaining capacity at a glance.

6000–7500mAh Delivered Capacity

Because of conversion and wireless losses, the usable energy delivered to a phone falls between 6000mAh and 7500mAh, or roughly 60%–75% of the rated cell capacity. Buyers who need the full 10000mAh to reach a device should plan for this efficiency gap. The bank operates at 3.7V and measures 4.06in by 2.61in by 0.85in.

Questions about this item

How do I confirm the W20 is charging my iPhone correctly after snapping it on?

The five LED indicators light up to show remaining power, and the 11 N magnetic grip holds the iPhone 12–17 series firmly so wireless charging starts instantly.

What comes in the box with the W20 and what must I buy separately?

The unit includes the 10000 mAh power bank with built-in kickstand and USB-C port; a USB-C cable and any wall charger are not included and must be purchased separately.

Which capacity version of the W20 should I choose for my iPhone 15?

The W20 is offered only in a single 10000 mAh lithium-polymer version, delivering roughly 6000–7500 mAh usable energy after conversion losses.
