Ultra-Slim Magnetic Power Bank
A pocket-thin MagSafe-compatible power bank that snaps onto your phone for wireless charging.
What it is
These ultra-slim magnetic power banks (like the UGREEN Magflow Air series) are only a few millimeters thick. They use strong magnets and Qi2 wireless charging so you can attach them directly to the back of a compatible iPhone and charge without a cable.
Most models offer 5,000–10,000 mAh capacity, 15W wireless charging, and a USB-C port for wired charging or recharging the bank itself.
How people use it
Snap it on when your battery is low and keep using your phone one-handed. Many people leave it attached during travel or long days out. The slim profile means it doesn’t add much bulk compared to traditional power banks.
Strengths and limitations
- Very thin and pocketable
- Convenient magnetic attachment
- No cable needed for iPhone users
- Best with MagSafe-compatible phones
- Wireless charging is slower than wired
- Capacity is lower than chunky power banks
