Why can't the electric straight screwdriver in the Mijia Tool Kit be charged?

If the electric straight screwdriver in the Mijia Tool Kit can not be charged, please refer to the following steps to troubleshoot:
1. The charging cable can not be properly connected, so please ensure that the cable is firmly inserted into both the screwdriver and the power source.
2. The charging cable or power adapter could be damaged, and replacing it with a compatible cable or adapter can resolve the issue.
3. Dust or debris in the charging port can affect electrical contact, so the charging port should be carefully cleaned before charging.
4. The power supply could be incompatible, and it is recommended to use a 5 V/1 A power adapter for charging.
5. Prolonged use can cause the screwdriver to overheat and activate high-temperature protection, so allow the product to cool down before charging again.
6. If the issue persists after troubleshooting, the product likely requires inspection or repair. Please contact the after-sales service center.
