Ultra-Slim Magnetic Power Bank

The WOOJONG 0.3 Ultra Slim Alloy power bank delivers 5000mAh capacity in a 0.3-inch profile that attaches magnetically to compatible iPhone 15, 16 and 17 models. Weighing just 0.21 lb, it slips into a tight pocket without a noticeable bulge, making it practical for daily carry and travel.

Sustained Output Behaviour

The unit supplies up to 18W total output via USB-C and 10W wirelessly, maintaining consistent delivery rather than peaking briefly. Magnetic alignment holds firm under movement, rated for 3000-plus shake cycles while charging continues uninterrupted. The 12N attraction force keeps the pack fixed during active use.

Thermals, Noise and Power Draw

An industrial-grade temperature control system keeps surface temperature close to body temperature during extended sessions, reducing heat stress on both the power bank and the attached phone. No moving parts mean silent operation. The 5000mAh cell recharges through the USB-C port for the next cycle.

Questions about this item

Does the 0.3 ultra-slim alloy body stay cool during all-day wireless charging?

The built-in temperature control keeps the power bank close to body temperature, dropping heat output by 50 compared with typical packs so it remains comfortable even after long use in hot weather.

Must my phone have MagSafe or a magnetic ring for the 12 N attachment to work?

Yes, the 12 N magnetic force requires MagSafe-compatible phones such as the iPhone 15, 16 or 17 series; non-magnetic cases will prevent the firm snap-on connection.

Can I still use the 18 W USB-C port while the 10 W wireless pad charges an older iPhone 12?

The 18 W USB-C output and 10 W wireless output operate simultaneously, so you can fast-charge a second device through the cable while an iPhone 12 charges magnetically.
