Operating Instructions
Charging DeWalt Batteries
Once the battery charging adapter is securely attached to your DeWalt battery and connected to a power source (wall or car charger), the adapter will begin charging the battery. The adapter features an 8-pin pure copper connector for efficient power transfer and a multi-stage charge indicator.
- Stage 1 Charging: Indicates the initial phase of charging.
- Stage 2 Charging: Indicates the battery is in the secondary charging phase.
- Pack Charged: Indicates the battery is fully charged.
- Hot/Cold Delay: Indicates the battery temperature is outside the optimal charging range. Charging will resume automatically once the temperature normalizes.

Power Bank Functionality
The bidirectional USB-C port on the adapter allows your DeWalt battery to function as a high-capacity power bank. This enables you to charge other USB-C compatible devices such as laptops, phones, or tablets directly from your DeWalt battery.
- Ensure the USB-C battery charging adapter is attached to a charged DeWalt battery.
- Connect your device (e.g., smartphone, tablet, laptop) to the USB-C port on the adapter using the 100W braided USB-C cable or another compatible USB-C cable.
- The adapter will automatically begin supplying power to your connected device. The output can reach up to 65W, suitable for high-draw devices.

Troubleshooting
- Adapter Not Charging Battery:

- Device Not Charging from Power Bank:
- Ensure the DeWalt battery attached to the adapter has sufficient charge.
- Verify the USB-C cable connecting your device to the adapter is functional and securely connected.
- Confirm your device is compatible with USB-C charging.
- Slow Charging:
- Ensure you are using the provided 100W braided USB-C cable, as lower quality cables may limit charging speed.
