Review on 🔦 10-Pack USB Powered LED Night Light Keychain Lamp for Camping - Portable & Bright (3-LED, Non-Dimming) by Kyle Miller

Much brighter than expected, more useful than expected. I just needed a simple power indicator so I could quickly and clearly see which of the gym treadmill's USB ports were actually getting power. I'd be happy with even a little light, but my goodness, these things are amazingly bright. I just held it over the LED with my thumb and it made my thumb glow like crazy. This worked great and then I started plugging them into other outlets around the house as little night lights.
