Product is very light in weight, but the LED lighting is great with different settings. Have not tried the USB outlet yet. It mentions battery back-up in the description, but not specifying anything else. I did find on the back of the unit a place to put two 'AAA' batteries. Should be clearer in the description. I like the different levels of light output, and LED being easy on the eyes. And also like having the time there as I can get working away on something and lose track of the time...so having it on display helps me not miss appointments. Overall excellent product and would recommend it to others.

Excellent LED desk lamp, very bright & good build, very good features, the usb outlet it charge my iphone6 plus with no issue.
