Emergency Multi-Functional Portable Charger

It's all black, made of plastic, and charges through a USB port. It has seven brightness levels: bright light, dim light, strobe, SOS, side white light, side white strobe, and blue-red strobe. Quite handy for close range, though it doesn't work as well from a distance. There's no adjustable distance, so it scatters a bit and is best for nearby use. The SOS strobe and the side light are useful. I think it's pretty practical, but it would be even better if there was a small magnet added behind the side light for easy attachment. Even though it has clips on both ends, sometimes a magnetic feature is really handy. I also wish there was a cover for the charging port to prevent water from getting in. I like to use it as a signal light while biking. Overall, it's a great product and worth buying.
