Stacy from Commerce township, MI

Stacy's hard drive is filling up after scanning a ton of photos. Her computer only has two USB ports. Does she need a hub in order to connect a USB thumb drive with an external hard drive?

It can be powered by your smartphone, an external battery charger, or even plugged into a computer. Once plugged into a power source it lights up to the rhythm of your music or even your voice! As you'll see in the video it does give off quite a bit of light for something that small. On Amazon, they are only $12.00 for three of them!
