🔦 DaFuRui 12pcs USB Light Keychain: Super Bright LED Mini Night Light for Laptop Keyboard - Portable USB Port Circuit Boards Review

These LEDs work with any USB stick and each one does exactly what it says on the tin. They are great for night lighting just about anywhere.

I have found uses for these flashlights anywhere there is a USB port. For example, I plugged one into my computer's front USB port and used it as a test light. I have several spare batteries for my phone and tablets and plugging one of these flashlights into the battery gives you a good flashlight.

Purchased just out of curiosity. These things are very bright because they are so small. They also use very little electricity. I've tried them with small USB power adapters, portable power banks, and even rechargeable AA batteries. Has worked every time. The only downside was that the plastic cases got very hot after about an hour of continuous use, so I wouldn't recommend leaving them unattended. Good to use as an emergency light if you have a portable USB power supply.

It's more like "let's buy a few and see what they do". kind of thing. There are different types of light, bright, dim, white and yellow. They work fine. I haven't kept them permanently attached to anything yet. If you're using them on a PC, they only glow in one direction. The bright ones that have a touch sensor turn them on/off. I think I can find a use for them somewhere. If they came out with different LED colors I would buy them. Can they be damaged on the keychain? You look strong enough.
