Car charger cannot be fully charged in time

Troubleshooting steps:

① The best charging temperature is 20-25 ℃. Lithium iron phosphate batteries are sensitive to temperature. If the temperature is too low or too high, the charging time will be prolonged.

② The charging current limit for the 100Plus is 5A, and the vehicle charging voltage is 12V. The power is relatively low, resulting the longer charging time.
