### Installation & Setup

#### What's Included in the Bundle

- 1 x Weatherproof Magnetic Enclosure Box
- 1 x 24,000 mAh Extended Slim Lithium-Polymer Battery Pack
- 1 x USB Charging Cable & Wall Adapter

#### Step 1: Initial Battery Charging

1. Connect the included USB cable to the input port on the **24,000 mAh Extended Battery Pack**.
2. Plug the adapter into a standard wall outlet.
3. Allow the battery pack to charge continuously for **8 to 12 hours** to reach full cell saturation before its first deployment. *(Note: This battery features overcharge protection, making it safe to leave plugged in overnight).*

#### Step 2: Preparing Your GPS Tracker

1. Ensure your compatible portable mini GPS tracker (such as the GL320, GL320MA, or GL320MG) is powered **ON** and has an active cellular data connection.
2. Confirm the tracker is successfully updating its location on your mobile app or desktop mapping software before sealing it in the case.

#### Step 3: Assembling the Kit

1. Open the heavy-duty latches on the **Weatherproof Magnetic Case**.
2. Insert the fully charged **24,000 mAh Extended Battery Pack** flat into the designated bottom compartment of the case.
3. Place your portable GPS tracker into its fitted slot directly alongside or on top of the battery pack.
4. Plug the battery's integrated power output cable securely into the charging port of your GPS tracker.

#### Step 4: Weatherproof Sealing

1. Inspect the internal silicone rubber perimeter gasket to ensure it is clean, flat, and free of debris.
2. Firmly press the case lid down and snap the side latches shut until they click locked. This compresses the gasket to provide a water-resistant barrier against rain, snow, and road spray.

#### Step 5: Placement & Mounting

1. Identify a flat, clean, magnetic metal surface on your asset (such as the upper frame rail underneath a vehicle or a structural steel support beams on a container).
2. Clean the target surface with a cloth to remove excessive mud, oil, or rust.
3. Apply the base of the enclosure to the metal surface. The built-in **heavy-duty neodymium magnets** will instantly grip with industrial-grade pull force.
4. **Safety Check:** Gently tug the box to ensure a flush, secure bond that can withstand high-vibration driving and harsh road environments.
