You never know when the electric will go out or you need a flashlight in a pinch. This flashlight takes 3 AAA batteries no need to wait for it to charge. This flashlight is a grab and go. I use it in my closets to search for things I need or in drawers and under the beds, etc. I have to search for my cat every now and again and this flashlight comes in handy. We have to search outside sometimes for her. This flashlight has great features, I like the anti-slip handle and that you can use it in light rain. It has 4 modes, high white light, low white light, SOS and high ultraviolet light. This flashlight is water resistant, drop resistance and small in size. Also great for any occasion like fishing, camping, and power outages. The UV can detect dog and cat urine. And you can check money to see if it's counterfeit. This little flashlight is very bright. Just keep extra AAA batteries around for when you need them.
