Compact Magnetic Power Bank

The Baseus E00303 is a 5000mAh lithium polymer power bank in Cosmic Black designed for iPhone users who want cable-free charging on the go. Its magnetic alignment works with MagSafe-compatible cases across the iPhone 12 through 17 series. The unit measures 3.4 by 2.3 by 0.5 inches and weighs 4.8 ounces.

20W USB-C Bidirectional Port

The single specification that determines fit is the USB Type C input and output rated at 20 volts. It delivers 20W wired fast charging and accepts the same rate to recharge the bank itself. Pass-through charging lets you power a connected device while the bank refills.

Braided Cable and Thermal Alloy

A USB-C braided cable is included for wired use and recharging. An NTC safety alloy manages heat dissipation during wireless and wired sessions. The bundle adds no extra adapters or proprietary software.
