2. Product Overview
2.1. Key Features
- Efficient Moisture Absorption: Contains 70 grams of non-toxic silica gel beads to effectively absorb humidity.
- Durable Construction: Features a robust Acrylonitrile Butadiene Styrene (ABS) exterior with strategically placed air vents for optimal airflow and moisture intake.
- Visual Status Indicator: A transparent display window allows for easy monitoring of the silica gel bead color. Dark blue indicates active absorption, while pink signifies saturation and the need for reactivation.
- Portable Design: Compact and lightweight, suitable for use in enclosed spaces up to 90 cubic feet, such as gun safes, camera bags, toolboxes, 3D printer filament storage boxes, and closets.
- USB-C Reactivation: Equipped with a built-in heater and a USB-C port for convenient and easy renewal of the silica gel's moisture-absorbing properties.
2.2. Included Components
- JJC Reusable Desiccant Dehumidifier (x1)
- USB-C Charging Cable (x1)

3. Setup
Before initial use, or whenever the silica gel beads indicate saturation, the dehumidifier must be reactivated.
- Connect Power: Plug the provided USB-C cable into the dehumidifier's USB-C port and connect the other end to a compatible USB power source (e.g., wall adapter, computer, power bank).
- Position for Reactivation: Place the dehumidifier vertically in an open, well-ventilated area with relative humidity below 90%. Do not place it in a sealed container while reactivating.
- Reactivation Cycle: Allow approximately 10 hours for the built-in heater to dry the silica gel beads. The beads will transition from pink (saturated) to dark blue (active).
- Disconnect: Once the beads are dark blue, disconnect the USB-C cable. The dehumidifier is now ready for use.

4. Operating Instructions
Follow these steps to effectively use your JJC Reusable Desiccant Dehumidifier:
- Placement: After reactivation, place the dehumidifier inside the enclosed space where moisture control is needed. Ensure it is positioned to allow air circulation around its vents.
- Moisture Absorption: The silica gel beads will begin absorbing moisture from the surrounding air.
- Monitor Status: Periodically check the transparent indicator window. The beads will gradually change color from dark blue to pink as they absorb moisture.
- Reactivation: When the beads turn pink, indicating saturation, remove the dehumidifier from the enclosed space and follow the reactivation steps outlined in Section 3. Setup.

5. Maintenance
Proper maintenance ensures the longevity and effectiveness of your dehumidifier.
- Cleaning: Wipe the exterior of the dehumidifier with a dry, soft cloth as needed. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the ABS casing.
- Silica Gel Integrity: The device is designed to securely contain the silica gel beads. If you notice any beads outside the unit, carefully collect and dispose of them. Do not attempt to open the unit to reinsert beads, as this may compromise its integrity and void any warranty.
- Storage: When not in use for extended periods, ensure the dehumidifier is fully reactivated (beads are dark blue) and store it in a dry, cool place.
