This little 350 lumen USB C plugin for Android phone. This little gadget is a 20 times brighter than your cellphone's LED lights. The light does not have battery itself which needs to be attached to your phone's USB C to provide power for illumination. You might carry it outdoor like an EDC just securely hook it to your hip bell for men hook it to your purse for ladies and attach it to the bottom of your cellphone if you need a real super bright flashlight or when it on the blackout. I tested out this little cellphone flashlight attachment and it's really bright like a daylight with a really beautiful event hotspot output like I attach it to my mobile phone and it can light up my whole basement stairs and the garage which normally only shed on a little dim light of the cellphone's LED just enough faint light illumination in the front to prevent me from stumble on objects. I also tested and compares it to my EDC Surefire P2X FURY TACTICAL flashlight 600 lumen and their illumination are pretty much similar but the Surefire's hotspot thrower a little bit farther.
