Ultrasonic Insect Repeller USB Rechargeable Portable Electronic Mosquito Deterrent for Camping Travel (Black)

• ULTRASONIC FREQUENCY FOR PHYSICAL REPELLING: The device emits sound waves between 34 and 70 kilohertz which are inaudible to humans but uncomfortable for mosquitoes and flies. The frequencies change randomly so insects do not become accustomed to them. No chemicals or scents are released so it is safe for use around children and pets. A technology choice for people who prefer physical pest control over sprays or lotions.
• FORTY HOUR BATTERY FOR EXTENDED OUTDOOR USE: The built in battery runs for up to 40 hours on a full charge depending on the mode. This covers several nights of camping or a long weekend of fishing trips. The battery charges fully in about one hour via USB. A power capacity for people who spend multiple days away from mains electricity.
• COMPACT SIZE FOR POCKET OR TENT HANGING: The device measures 4cm by 4cm and weighs very little so it slips into a trouser pocket or clips onto a backpack. A loop lets you hang it inside a tent or from a gazebo frame. The small size does not take up valuable packing space. A portability design for people who travel light and need mosquito protection without bulky gear.
• NO CHEMICALS FOR SENSITIVE USERS: The repeller works without DEET or other insect repellent chemicals. People with skin conditions who cannot use sprays can wear this on a belt loop. The lack of scent means it does not interfere with food or drink at outdoor meals. A hypoallergenic design for people who react to common insect repellent ingredients.
• THREE SIXTY DEGREE COVERAGE FOR ROOM USE: The device projects sound in all directions so one unit can protect a small bedroom or a tent interior. For larger spaces you can use multiple units or position it near where you are sitting. The coverage does not require line of sight like some electronic repellents. A placement design for people who want protection without aiming the device at specific entry points.
