Snap-On Magnetic Charging for iPhone 12-17

The TORRAS PB4D MiniMag is a 5000mAh wireless power bank that attaches magnetically to compatible iPhone models from the 12 series through the 17 series. It delivers 7.5W wireless output and 18W wired output via its USB-C port. The 0.3in thin profile and 4oz weight make it barely noticeable when snapped to the back of a phone for all-day battery life on the go.

Passive Cooling With NTC Temperature Control

The lithium-cobalt cell operates at 9V DC and relies on an integrated NTC temperature control chip to manage heat during fast charging cycles. No fans or active cooling are present, so the unit runs silently in a pocket or bag. The supplier notes a full phone charge can complete in about two hours under normal conditions without thermal throttling concerns.

Ultra-Slim 0.3in Build With USB-C Cable Included

At 0.3in thick the power bank adds minimal bulk and uses a 13N magnetic array to stay firmly attached during movement. A USB-C to USB-C cable is included for wired 18W charging or recharging the bank itself. The Glacier White finish resists fingerprints. Not suited for users needing 25W+ wireless speeds, multi-device simultaneous charging, or capacities above 5000mAh.

Questions about this item

How do I attach the 0.3 in thick MiniMag to my iPhone 15 for MagSafe charging?

Align the built-in magnets with the phone's MagSafe ring; the 13 N magnetic force snaps it on and holds it without a cable.

When will the internal lithium-cobalt cell need replacement?

The sealed 5000 mAh cell is not user-serviceable; replace the entire power bank once run-time becomes unacceptably short.

What stops the 7.5 W wireless output from running continuously?

The NTC temperature-control chip throttles output when the unit gets hot, so sustained wireless charging slows down until it cools.
