Ultra-Thin 5000 mAh Power Bank

The MOMAX IP157L is a 0.3 inch slim power bank with a 5000 mAh capacity and a built-in USB-C cable. It delivers PD 20W wired fast charging for iPhone 15, 16 and 17 models as well as Samsung, Google and Android devices. A 14N magnetic grip attaches securely to the phone back for hands-free use without wireless charging.

Sustained Charging with Thermal Guard

Dual graphene thermal control and an NTC thermistor chip perform 36000 AI temperature checks per hour during operation. The high-density lithium battery cell maintains stable output under continuous load rather than throttling after a short burst. The integrated 2.8 inch USB-C cable is rated for over 20000 bends, ensuring the connection stays reliable through repeated daily plugging and unplugging.

Check Compatibility Before Buying

This unit has no wireless charging function, so buyers who want cable-free magnetic charging should look elsewhere. It provides a single USB-C output with a short integrated cable, so users needing multiple simultaneous ports or longer reach will need a different solution. The 5000 mAh capacity suits one phone top-up but will not fully charge larger tablets or laptops.

Questions about this item

Does the dual graphene thermal control and 36000 AI temperature checks per hour keep the IP157L cool and quiet during all-day use?

The dual graphene thermal control and NTC thermistor chip perform 36000 AI temperature checks per hour, actively managing heat so the slim power bank stays cool and silent during extended wired fast charging sessions.

What device port and cable length does the built-in 2.8 USB-C cable require on my phone or tablet?

The integrated 2.8-inch USB-C cable plugs directly into any USB-C port on iPhone 15/16/17, Samsung, Google Pixel, iPad or Android devices — no extra cable or adapter is needed.

Will the 14N magnetic grip hold the 4.16 oz power bank securely to a non-MagSafe Android phone or older iPhone?

The 14N magnetic suction is designed for MagSafe-compatible models; on phones without MagSafe rings the magnetic hold will be weak or absent, so a MagSafe case or adhesive ring is recommended for hands-free use.
