Magnetic Power Bank for iPhone 12 to 16

The COOAV MA100 is a 12000mAh lithium-polymer power bank with MagSafe-compatible magnetic alignment. It targets iPhone 12, 13, 14, 15 and 16 series users who want cable-free charging while moving. The unit measures 4.56 in by 3.66 in by 1.02 in and comes in black. It is sold new and airline-approved for carry-on travel.

Wireless, USB-C and USB-A Outputs

Three charging methods are built in: up to 15W wireless, up to 20W PD via USB-C and up to 22.5W PD via USB-A. All three ports can operate simultaneously, letting you power three devices at once. Magnetic attachment works only with MagSafe cases or bare iPhones; non-magnetic cases block the connection and cases thicker than 2.5 mm may prevent charging.

12000mAh Capacity Decides Suitability

The 12000mAh cell delivers roughly two full charges for an iPhone 16 Pro, making it suitable for day trips or long commutes. Buyers who need more stored energy for multi-day off-grid use should look elsewhere. iOS 17 thermal management may pause charging at 80 percent until the handset cools, which is normal behaviour.

Questions about this item

How often will the lithium-polymer cells need replacing?

The 12000mAh lithium-polymer pack is sealed and not user-replaceable; expect several hundred charge cycles before capacity drops noticeably.

What stops the 15W wireless output during long sessions?

iOS 17 thermal management pauses charging at 80% if the iPhone overheats; removing the case or moving to a cooler spot lets it resume.

How warm does the 22.5W USB-C port get under all-day load?

Heat is normal during fast charging; the slim 1.02in profile dissipates warmth, and output throttles back if internal temperature rises too high.
