  4. Verify Connection: Once connected, the vacuum's charging indicator (if present) should activate, signaling that charging has begun. Refer to your vacuum's manual for specific charging indicator behavior.

3. Operating Instructions (Charging)

Once the cable is properly connected as described in the "Setup Instructions" section, the charging process will begin automatically. The cable is designed to provide a stable power supply for charging the 2200mAh battery of your FUOAYOC ATJ-2166 vacuum.

  • Charging Time: Charging time will vary depending on the battery's current charge level and the output capacity of your USB power source.
  • Charging Indicators: Monitor the charging indicator on your FUOAYOC ATJ-2166 vacuum to determine the charging status. The indicator typically changes color or state when charging is complete.
