So close to perfect

I know this is supposed to be a backup battery, but it's also a really cool very slim flashlight, or it could be. I just with they had thought a little more about the way the buttons work. As an astronomer and pilot, I want a light that will stay in red mode unless I take an explicit action to change it. With this light if you touch the button the wrong way you get white light again, wiping out your night vision. oops.

Good unless your phone has a case on it.

I like the light and what it is suppose to do. Charge your phone in an emergency. However, if your phone has a case on it there is a very good chance the type c connector will not plug in far enough to start charging. I have to take my case off to charge it. I would say 5 stars if you have no case on your phone and 3 stars if you do.

Irwin Feuerstein
Its too big

To keep it short, good amount of light, appears well build, but its just too big, at least in my opinion, to be called a keychain light.

David Crupi
Flat Flashlight

Great little, flat flashlight.

Robert LaPietro
