portable USB electric mosquito repeller and heater.

• Power Source. Plugs directly into any standard 5V USB-A port, such as a power bank, laptop, car charger, or wall adapter. It does not contain an internal battery. • Heating System. Uses constant-temperature heating (listed on the box at 110°C) to rapidly activate the repellent mat within a few minutes. • Coverage Area. Designed to protect a small zone of roughly 10 to 20 square meters (about 100 to 215 sq. ft.), making it best suited for tents, bedrooms, or small workspaces. • Portability. Weighs roughly 33g to 49g (listed as 49g on this box) and measures around 6 cm × 4 cm, making it easy to carry for camping, fishing, or travel. • Refill Compatibility.
