The 2-Outlet 1875W Converter Set with USB Port and 4 Adapter Plugs enables you to plug in three devices at once. It is designed for devices rated for 26-1875 watts and up to 10A. The unit has a bypass outlet for dual-voltage devices rated for 110/120-230VAC that do not require voltage conversion. There is an extra power outlet for single-voltage devices that converts 220/240VAC foreign electricity to the 110/120VAC used in North America. The converter is also equipped with a USB port. Four adapter plugs rated up to 250VAC, 10A are included, enabling you to use the converter all over the world. The first plug is for use in Great Britain, Ireland, Africa, Hong Kong and Singapore, while the second is for North America, South America, Japan and the Caribbean. The third plug can be used in Australia and New Zealand. The fourth and final plug is for use in Southern Europe, the Middle East, Africa, Asia and the Caribbean. Insulated pins, a safety shutter, and raised finger flanges offer added security. The flanges also make it easier to withdraw the adapter plugs from the outlets.
