International travelers are facing a mix of power voltages and plugs standards around the world. Decades old standards were based on politics more than sound physics.

Modern portable devices such as computers, monitors, come with power adapters that work between 100V and 240V, 50Hz or 60Hz. However, special plugs are needed for practical use in different countries in Europe for example. Airports and hotels are the most noticeable locations of such problems.

Universal adapters take a significant space and weigh over 400gm in some cases. Some adapters cannot be plugged into power strips next to each other. Devices such as laptop computers and mobile phones connected to 220V outlets are subject to high inrush current which can destroy them very fast. Power outlets in central EU do not have clearly defined neutral power line pin which can be a problem in some electronic devices.

A unified voltage and power outlets worldwide standard is proposed in this document. Countries with 220V power standards would adopt 110V for use with low power devices such as TV, microwave ovens, computers, medical and bathroom devices, and lights.

To accomplish this a 10kW transformer would be sufficient to convert voltage from 220V to 110V. Such a transformer mounted at building power panels would take little space. Power outlets with clearly defined polarized pins and their sizes for 110V would be the same kind as used in the USA.

This conversion could be accomplished in just a few years. It would make manufacturing and warehousing power supplies for electronics devices significantly less expensive, and more convenient for travel.
