LIGHTORS HandGrip Battery Pack is a portable charger with multiple functions. The device has additional functions including hand-gripper for exercise, flashlight, insect repeller, and emergency alarm. We have completed performance tests and developed a prototype. There are a few improvements to be made including scratch-resistant and insect-repeller ultrasound effects.

When squeezing a hand gripper repeatedly, it can cause scratches on the surface of the bottom. Based on years of experience, we have the know-how of designing product and metal mold to overcome the challenge.

The second challenge is to increase the effects of the insect repeller. The kind of mosquitoes that bite human/animal for blood tends to flee from male mosquitoes or unfamiliar sounds. It’s also suggested that the sound of dragonfly’s, the mosquitoes natural predator, repels mosquitoes and other insects. The device is designed to reproduce such sounds.

Our team has successfully developed a system that reproduces changing frequencies to prevent the female mosquitoes from becoming immune to the same frequency. We are about to apply the upgraded technology to the device.
