Magnetic Power Bank for iPhone

The Wowuwoai W20 is a 10000mAh lithium-polymer power bank that attaches magnetically to compatible iPhone models. It delivers up to 15W of wireless power through MagSafe alignment and 20W via its USB-C port with PD and QC 3.0 support. A fold-out kickstand props the phone for hands-free viewing while charging. Five LEDs show remaining capacity at a glance.

11N Magnetic Grip

An 11N magnet array locks the bank to MagSafe cases on iPhone 12 through 17 and Air series in one second. The hold stays firm during movement so the coil stays aligned and wireless output remains steady. No cables are required for the magnetic connection, leaving the USB-C port free for a second device or for recharging the bank itself at 5V.

Best for MagSafe iPhone Owners

Travellers and commuters who want cable-free top-ups and a built-in stand for video calls will benefit most. Users with non-MagSafe phones or cases cannot use the magnetic feature and would need a different wireless charger. Anyone needing more than 10000mAh of capacity or wireless output above 15W should look at larger banks.

Questions about this item

How many full phone charges does the 10000mAh capacity actually deliver?

The 10000mAh lithium-polymer cell typically provides roughly two full charges for an iPhone 13 or 14, depending on the model's own battery size and wireless efficiency losses.

What charging speeds do the USB-C PD and wireless modes reach?

USB-C Power Delivery outputs up to 20W for fast wired charging, while MagSafe-compatible wireless charging delivers up to 15W when the phone snaps on.

Will the 4.06 x 2.61 x 0.85 inch brick fit in a shirt pocket with an iPhone attached?

At just over four inches tall and 0.85 inch thick, the power bank adds noticeable bulk; it fits most trouser pockets but will be tight in a standard shirt pocket when magnetically mounted.
