Does it come with a charging cable?
The box typically includes a high-performance cable, but always check the specific retail packaging contents.

Troubleshooting
Device is not charging at maximum speed
Ensure you are using the correct USB-C port and a cable rated for high-wattage (at least 5A/100W or 140W) charging.
Power bank charges very slowly
Verify that your wall adapter supports high-wattage Power Delivery (PD) and is not a standard low-power phone charger.
Device disconnects intermittently
Check the USB cable for physical damage and ensure the connection to both the bank and your device is firm.

Setup, Compatibility & Care
To begin using the CUKTECH 15 Ultra, ensure you are using a high-quality, USB-IF certified USB-C cable capable of handling at least 100W or 140W. To recharge the power bank, use a dedicated PD wall charger with at least 65W or higher for the best performance; using a standard 5W or 10W wall block will lead to extremely long recharge times.
