It is a speaker. It's a flashlight as well. But that's not all the Outdoor Tech Buckshot Pro Speaker Flashlight does. Thanks to the rechargeable lithium-ion battery, it also serves as a power bank for your USB-charging devices, and doubles (or quadruples) as a speakerphone. It's water-resistant and impact resistant, with built-in playback control buttons, 10-hours of battery life, and an included bicycle handlebar mount for those times when two wheels and a horn just aren't enough.
