One of the trends we’ve seen lately has been USB charging: it’s everywhere. With microUSB now the standard for mobile phones (except the iPhone), it’s only a matter of time until USB charges your laptop computers.
The people behind the USB standard have come up with a change to the port that should bring with it more power, with an increase from the 5 watts most USB power packs send out to a maximum of 100 watts.
These days, laptops are packaged with a variety of power packs, with numbers ranging from 30W to 65W. Few tablets can be charged from the standard 5W USB power supply either, with the Apple iPad 2 requiring a 10W charger and the Asus Eee Pad Transformer bundling in a 15W.
The good news is that once this solution is in place, you won’t have to lug all of your adaptors with you from place to place, as it should create a “one size fits all” scenario and provide only the power the device needs. With a surplus of electricity in this update to the USB specification, laptops could well be charged from a USB port.
