Apple and Google are leading the push towards a standardised charger which could power any laptop, regardless of which brand name it carries.
Both companies have this week unveiled new notebooks which adopt the new USB Type-C connector in place of a conventional power socket which typically varies between laptop makers and even models.
Apple led the charge on Tuesday with its new super-slim MacBook while and Google followed overnight with the launch of the Chromebook Pixel 2, and also announced that future editions of its flagship Nexus smartphones and tablets would use the same plug.
While USB Type-C is saddled with a uninspiring name that begs to be replaced with something cooler and more mainstream-friendly, the technology itself will prove a Godsend to road warriors.
The single plug and cable is capable of charging a laptop, providing high-speed USB connectivity and also streaming HD video HD to an external monitor.
USB Type-C uses a compact connector roughly the same size as a micro-USB or Apple Lightning plug, but unlike previous USB connectors it's reversible, so there's no need to flip it over and over while trying to make it fit any particular device.
Replacing the riot of manufacturer-specific laptop chargers and power sockets with a single universal plug is something which Intel and several industry bodies have been championing for years.
Many business travellers can attest to the frustration of having to hunt around for expensive and sometimes hard to find chargers for their brand of laptop when the original charger and cable are either lost in transit or left at home.
Apple's adoption of USB Type-C (won't somebody please give this tech a sexier name, and soon?) is particularly significant because the company has previously relied on proprietary connectors such as the MacBook and MacBook Air's MagSafe.
However, Apple's decision to add just one USB Type-C port to its new MacBook has attracted plenty of criticism because it will force most customers to buy add-on expansion dongles if they want to connect a USB drive or devices such as 4G/3G modems while the laptop is charging.
Google has more wisely fitted two USB Type-C connectors to the Chromebook Pixel 2, along with a pair of regular USB 3 sockets.
We'll be watching the next wave of Windows-powered notebook and ultrabook releases with great interest, to see if the likes of Dell, HP, Lenovo, Toshiba and other leading laptop brands also make the switch from brand-unique power sockets to what we hope will become the new standard of USB Type-C.
Now, about that name...
