Ultra-slim credit-card form factor

This Miady HQW021 power bank measures 3.54 by 2.36 by 0.55 inches and weighs 0.24 lbs. Its 5000mAh lithium-polymer cell delivers reliable backup power for iPhone 12 through 16 series. Magnetic alignment snaps the pack to the phone back for cable-free charging. Five white LEDs show remaining capacity in 25% steps while a blue LED confirms wireless charging is active.

Replaces bulky wired packs for daily top-ups

The 5W wireless output suits overnight or desk-side charging rather than rapid refills. Wired USB-C output reaches 12W for faster top-ups when a cable is acceptable. USB-C input recharges the bank in about four hours using a 5V 2.0A adapter. Buyers needing 15W wireless speeds or 22.5W wired output should consider higher-spec models.

Fits pocket or small bag without adding bulk

Credit-card footprint leaves room for other essentials in tight pockets or minimalist bags. Magnetic hold works through compatible MagSafe cases so the phone stays protected. USB-C port handles both input and output, reducing the number of cables carried. No pass-through charging is supported, so the bank must be recharged separately.
