Is the Yubo charging treasure 10000 mAh broken after charging for more than 20 hours?

This is not normal. It may be broken, or there may be something wrong with the charger or data cable. The real 10000 should be full in about 6 hours. It is recommended to check whether there is any problem with the charging head and charging cable. If it still doesn't work, you can consult the after-sales service. It is recommended to use the original charging head to charge.
