24V is better. Because the ideal one charger input voltage can work between 12V-24V, but 24V input voltage can make the charger work more efficiently, charging faster, and charging time shorter.
In addition, if the input voltage of 12V is used to charge, the charger temperature may be too high, the equipment heating and other problems, affecting the life of the charger and the service life of the equipment.
Therefore, we recommend choosing an input voltage of 24V to charge the ideal one.
It should be noted that when selecting 24V input voltage, you need to use a power adapter that meets the specifications, otherwise it may cause adverse effects on the device.
At the same time, it is also necessary to ensure that the room temperature is appropriate when charging, if the ambient temperature is too high, it will affect the charging efficiency.
