The battery is charged only a small amount when you purchase the pen. Be sure to fully charge the battery for the first time.
Full battery charging time | About 2 hours 20 minutes | Stop charging after the battery is full (the indicator light goes from red to green) | |
Time to use | Speaker | About 7 hours of use | Battery life depends on usage, temerature, usage time, etc. |

As the battery is consumable, the charging time and usage time will be reduced.
The pen contains an integrated Li-Po battery. Ensure that the battery is charged or stored at room temperature between 5 ° C and 35 ° C. Stop charging when the pen LED turns from red to green when fully charged. Charging for too long (over 3 hours) can lead to reduced battery life. Pens which are not used for a long time can also cause battery drain and error. To avoid battery exhaustion, charge even when the pen is not in use.
As the battery is consumable, the usage time will be reduced. Replace the battery if the battery longevity drops below 50% or leaks. When the pen is not working or the battery has been consumed by the time when you buy the pen, please contact Sun Edu’s customer service: 1800-8064 or our website.
