Your SPC GRAVITY charges only through its USB-C port.
To charge your SPC GRAVITY, we recommend using the supplied cable. Charging time should not exceed 4 hours.
Please note that if the screen is on during charging or the tablet is being used heavily, this time may increase.
Sometimes, if the battery is very low, your tablet may need a few minutes to up to 2 hours to start charging after plugging it into a power source. Don't worry, after this time, the battery will reach the minimum level to power on.
You can find more information on how to charge your tablet in the section Powering on, charging and battery.
