3 LED Solar Flashlight Whistle Keychain is a very suitable product for promotion and advertising.
At this stage, 3-LED solar flash light is popular and many customers buy it. So we added whistle function on the basis of 3 LED solar flash light. Maybe you think whistles are useful only in team training. But the strongest function of whistles is not in the area of regiment building training. Whistles are mainly used in special places. For example, if you're stuck somewhere and need to be discovered, then voice is an important choice. Moreover, the whistle sounds are more penetrating and less labor-intensive than our own cries, allowing us to reduce energy use.
3 LED Solar Flashlight Whistle Keychain can be charged by solar energy, as long as the sun can be charged, so this lamp can be used in many emergencies. And our 3 LED Solar Flashlight Whistle Keychain has a longer life than the general Keychain light. Ordinary Keychain light uses only button batteries. The battery runs out of electricity and the life of ordinary Keychain light is over. Our 3 LED Solar Flashlight Whistle Keychain can be charged with solar energy after the battery is used up, so the lifetime of our 3 LED Solar Flashlight Whistle Keychain can extend to the end of the real life of 3 LED Solar Flashlight Whistle Keychain.
