Night Scope Classic Rechargeable LED Warm Knit Beanie Head Light Hat Headlamp for Outdoor Activities

How do you charge it nothing came with it to change it !

Anyone else’s light just won’t charge? am i missing something? i tried putting it into a usb every way i could and no red charging light comes on...

How do you know when the rechargeable LED light is fully charged?

I have one of your beanie hats. it is fully charged but it won’t light up. it’s brand new and never used. what can i try to make it work?
