Frequently Asked Questions

Q: How is the SHINEKNOT USB COB Key Light charged?

A: The light features a built-in 3.7V rechargeable battery that charges via a standard USB connection. Simply plug it into any USB power source — a laptop, wall adapter, or power bank — and it's ready to go. Batteries are included so no extra purchases are needed.

Q: Can this key light be used as a bicycle warning lamp and a work light at the same time?

A: Yes! Its versatile pen-clip design allows you to attach it to a bicycle frame, backpack strap, hat brim, or pocket — making it equally effective as a bicycle visibility warning lamp, a hands-free outdoor running light, or a compact portable work light. The 360° beam angle ensures you're seen from all sides.

Q: How bright is the USB COB Key Light?

A: This light outputs 500 lumens from its 5W COB LED, making it significantly brighter than most keychain or pen-clip lights on the market. The wide 360° beam angle spreads that brightness evenly for maximum visibility and utility.
