Do BenQ ScreenBars need a separate power adapter?
Reviewer consensus
No. Across the ScreenBar lineup the bars are USB-powered, drawing from your monitor's or laptop's USB port (the original uses USB-A, while the Pro uses USB-C). That keeps the desk free of extra plugs, a convenience verified-purchase reviewers frequently mention. The trade-off is that they rely on your computer being powered, so they aren't ideal as standalone room lighting.
