TIP BLACK 360 Lumen Keychain Flashlight

I bought one of these lights when they first came out. They are amazing. Like a hand held flamethrower. The only bad thing about them is the lack of a cover for the micro USB charging port. I fixed that with a .25 cent plug from Amazon.

Now if I’m asked if I have a flashlight I say “just the tip”.

What’s the runtime on this?

Per the features:

The built-in Li-ion battery provides up to 90 minutes at 150 lumens and the USB charging port offers convenient power access.
