• Charging current: 4A
• Power output: 48W
• Compatible battery types: AGM, GEL, STD
• Cable length: 1.8 meters
• Integrated LED status indicator

How to use

To use the charger, first ensure that the battery is disconnected from the vehicle or device if necessary. Connect the charger clamps to the corresponding battery terminals, ensuring the positive clamp is attached to the positive terminal and the negative clamp to the negative terminal. Once the connections are secure, plug the charger into a standard wall outlet. The LED indicator will illuminate to show the charging status. Once the battery is fully charged, disconnect the charger from the power source before removing the clamps from the battery terminals.

What to consider before purchase

• Verify that your battery voltage is exactly 12V
• Confirm that your battery chemistry is AGM, GEL, or standard lead-acid
• Ensure the charging current is appropriate for your battery capacity
• Check the length of the cable to ensure it reaches your power outlet

Usage recommendations: Always perform charging in a well-ventilated area to prevent the accumulation of gases. Regularly inspect the cables and clamps for any signs of wear or damage before each use to ensure safe operation.
