DJI Mini 4 Pro Charging Hub, Charger & Battery Charging Guide
Work out whether the fault is the hub, power adapter, USB-C cable, battery or aircraft charging path before ordering a replacement.
Charging routes
Aircraft or compatible hub
Power source
Suitable USB-C PD
Hub behaviour
Sequential, not simultaneous
Battery not charging in the hub
Charges in aircraft
Check the hub, cable and power adapter.
Charges in hub only
Check the aircraft port and charging path.
Charges nowhere
Test the battery, charger and cable; a deeper fault is less common.
Hub has no power
Confirm charger output and USB-C Power Delivery support.
Try a known-good cable and suitable charger.
Inspect the USB-C connection.
Test batteries individually.
Can I use a phone charger?
Possibly, if it provides suitable USB-C Power Delivery. A lower-output charger may work slowly; an older low-output adapter is a poor diagnostic baseline.
