Can i use a 220v power strip with usb ports on 110v?
Through the powers of searching the web, multiple sellers of this device list it as having a rated voltage of 100-250 VAC. The websites also show what is stamped on the boiler plate in your picture as being the max rated power. Here is a link to one of the many sellers I found for this device although there does not seem to be a manufacturer's website and no datasheet.

All that to say, it'll probably work but you only have marketing to go on for that.
