Why You'll Love It

• High-Efficiency Moisture Absorption: Porous silica gel particles rapidly capture excess moisture in spaces up to 0.5–2 cubic metres, shielding gear from mildew, rust, and humidity erosion.
• Rechargeable & Reusable: Built-in low-voltage heating module with a standard Type-C port — simply plug in any USB source for 2–3 hours to fully restore absorption capacity. Save money and reduce waste versus disposable packs.
• Color-Change Saturation Indicator: Silica gel particles visibly change colour when fully saturated, so you always know exactly when it's time to recharge — no guesswork needed.
• Durable Leak-Proof Shell: BPA-free, food-grade transparent PP plastic housing with evenly spaced ventilation slots keeps particles safely contained while allowing full air circulation. Check desiccant status at a glance without opening the case.
• Universal USB Compatibility: Works with power banks, laptop ports, wall chargers, and car USB ports — recharge at home, in the office, or on the go.
• Safe & Non-Toxic: Non-corrosive, non-toxic silica gel and BPA-free shell — safe for food storage, baby product storage, and any environment with strict safety requirements.

Frequently Asked Questions

Q: How do I know when the dehumidifier card needs to be recharged?

A: The food-grade silica gel particles inside the card change colour noticeably when they reach maximum absorption capacity. Simply watch the dedicated dry-wet display window — when the colour shifts, it's time to plug the card into any USB Type-C power source for 2–3 hours to fully regenerate it.

Q: What USB power sources can I use to recharge the dehumidifier card?

A: The card features a universal Type-C interface compatible with virtually any standard USB power source — including wall chargers, power banks, laptop USB ports, and car USB adapters. No proprietary charger is required, making it easy to regenerate at home, in the office, or while travelling.

Q: Is this dehumidifier card safe to use around food or baby products?

A: Yes. The card uses food-grade silica gel desiccant particles and a BPA-free transparent PP plastic shell. No harmful substances are released during normal moisture absorption or the USB regeneration process, making it suitable for food storage containers, baby product storage areas, and other environments with high safety requirements.

Q: What size enclosed space does this card cover?

A: This card is designed to effectively manage humidity in enclosed spaces ranging from approximately 0.5 to 2 cubic metres — ideal for camera bags, lens cases, jewelry boxes, small drawers, file cabinets, and collectible display cases.
