10000mAh Magnetic Power Bank for iPhone 12 to 17

This INIU P731 power bank stores 10000mAh in a 1.4cm slim profile and attaches magnetically to iPhone 12 through 17 series handsets. Qi2-certified 15W wireless charging refills an iPhone 16 from 20 to 57 percent in 25 minutes. An attached 12cm USB-C cable delivers up to 45W wired power for broader device support.

Replaces 5000mAh packs and 7.5W MagSafe chargers

The 10000mAh cell yields roughly 1.9 full charges for an iPhone 16, nearly double the runtime of typical 5000mAh units. Qi2 15W wireless cuts the 20-to-57-percent top-up to 25 minutes versus 7.5W alternatives. The integrated USB-C cord removes the need to carry a separate cable for wired 45W PD charging.

Check iPhone model and wireless-case thickness

Magnetic alignment and 15W wireless speeds work only with iPhone 12, 13, 14, 15, 16 and 17 series; earlier iPhones and Android phones charge wirelessly at reduced rates without magnetic hold. Verify that any protective case supports MagSafe or Qi2 pass-through, as thick or metal-backed cases can block coupling. The unit measures 4.1 by 2.8 by 0.5 inches for pocket fit.

Questions about this item

How thick is the 10000mAh magnetic power bank and will it fit in a slim pocket?

The unit measures 1.4 cm thick, 4.1 in long and 2.8 in wide, making it the slimmest 10K magnetic bank on the market and easy to slide into a pocket.

What is the correct way to attach the USB-C GoCord for wired PD 45W charging?

Plug the attached 0.4 ft USB-C GoCord into one of the two USB-C ports and your iPhone 16; the bank negotiates 45 W automatically — users often forget to seat the short cord fully.

When should I expect the lithium-polymer cell to lose enough capacity to need replacing?

The 10000mAh lithium-polymer cell is built for long cycle life; under normal daily use it delivers 1.9 iPhone 16 charges per cycle for years before capacity falls to a level that warrants a new unit.
