Slim Magnetic Power Bank with Built-In Cable

The MOMAX IP157 is a 5000 mAh portable charger designed for smartphones and small USB-C devices. Its 0.3 inch profile and integrated 2.8 inch USB-C cable allow it to attach magnetically to the back of a compatible phone for cable-free carrying. The unit supports Power Delivery at up to 20 W for rapid wired charging.

For Daily Top-Ups, Not Extended Off-Grid Use

This capacity suits commuters and travellers who need a single full phone charge during the day. The magnetic grip and tucked-away cable keep pockets tidy. Users who require multiple device charges, laptop power, or wireless charging should consider higher-capacity or wireless-enabled alternatives.

5000 mAh Capacity Decides the Fit

The 5000 milliampere-hour cell determines how much power is available between wall outlets. It typically delivers one complete smartphone charge. Buyers needing more stored energy must select a larger power bank.

Questions about this item

How do I attach the IP157 power bank to my iPhone 15 for charging?

The 14N magnetic grip lets the 0.3" slim power bank snap onto the back of compatible iPhones; then plug the built-in 2.8-inch USB-C cable into the phone's port to start PD 20W wired charging.

When will the built-in USB-C cable need replacement on the IP157?

The integrated cable is rated for over 20,000 bends, giving it a lifespan 400% longer than standard cables, so replacement is unlikely during normal use.

What limits sustained fast charging on the IP157 power bank?

Dual graphene thermal control and 36,000 temperature AI monitors per hour manage heat, while the 5000mAh capacity determines total energy available before the power bank itself needs recharging.
