Before first use, fully charge the 20V lithium battery pack. The battery can be charged directly via the USB-C port on the battery itself using the provided USB-C fast charger, or by connecting the 12V car adapter to the inflator's 12V DC input port.

• Connect the USB-C cable to the battery pack and a suitable USB power source.
• Alternatively, plug the 12V car adapter into your vehicle's 12V outlet and then into the inflator's 12V DC input port.
• The battery level display on the battery pack will indicate charging status.

5.2. Attaching the Battery Pack

Align the battery pack with the base of the inflator handle and slide it in until it clicks securely into place.
