Your GRAVITY 5 Pro only charges through its USB-C port.
To charge your GRAVITY 5 Pro, we recommend using the supplied cable. Charging time should not exceed 2-3 hours using a USB-PD charger of at least 18W.
Remember that, if during charging, the screen is on or you are using it intensively, this time could increase.
Sometimes, if the battery is very low, it may take from several minutes to 2 hours after connecting the charger to the power outlet for your tablet to start charging. Don't worry, as after this time, the battery will reach the minimum battery level for booting.
You can get more information on how to charge your tablet in the section Power, charging, and battery.
