Overview
A step-down converter circuit lowers European mains voltage to the lower level US devices expect, with a USB power delivery port and a set of plug adapters. Three outlets share the output.
One block gives US devices a lower voltage and a set of plug shapes for many regions. The limit is the output ceiling, because heating appliances may exceed it and the listing does not detail protection features.
Who it's for
Travelers charging phones, laptops and low-power gear abroad get a converter with a USB port and multiple plug styles. People running hair dryers, kettles or other heavy loads should check the wattage first.

Performance notes
