1× Utility Fast Charge Case
Compatibility
X4 Air batteries (X4 Air camera)
How it works (quick start)
Insert batteries: Align the battery notch with the slot’s triangular mark and press down until the orange top indicators are no longer visible.
Charge the case batteries:
Use a USB-C power adapter (9V⎓2A or 9V⎓3A recommended; 5V supported) with the USB-C port or the built-in USB-C cable.
Charge the camera too (optional): With batteries in the case, use the built-in USB-C cable to connect the case to X4 Air, and a second USB-C cable from the case to wall power.
Power bank mode: With ≥30% charge in at least one inserted battery, connect your USB-C device to the built-in cable to top up on the go. (The case prioritizes the battery with the most charge.)
