Ultra-Slim 5000mAh Magnetic Power Bank

The Miady HQW021 is a credit-card-sized 5000mAh lithium-polymer power bank that attaches magnetically to iPhone 12 through 16 series models. At 3.54 by 2.36 by 0.55 inches and 0.24 lbs, it fits in a pocket and serves as a lightweight backup for daily top-ups rather than full recharges.

5W Wireless Plus 12W USB-C Output

The built-in MagSafe-compatible pad delivers 5W wireless charging that starts automatically on contact, while the USB-C port supplies up to 12W wired output and accepts 5V 2.0A input for a four-hour recharge. Five white LEDs show battery level in 25% steps and a blue LED confirms wireless charging is active.

Snap-On Convenience With Simple Controls

Magnets hold the pack in place during use; if attraction feels weak, wiping both surfaces restores grip. A single press of the side button wakes the pack when it appears unresponsive. No cables are included, so users must supply their own USB-C lead for wired charging or recharging the bank itself.

Questions about this item

Will the lithium-polymer cell need replacement after many charge cycles?

The 5000mAh lithium-polymer cell is built into the unit and is not user-replaceable; when its capacity fades the whole power bank is replaced.

What limits output during long wireless charging sessions?

Wireless output is capped at 5W, so that is the first limit reached under sustained use.

How warm does the pack get when it runs all day?

The supplier notes it is normal for the power bank to heat up during wireless charging.
