USB 3.0 to ramp up the power to 100 watts

We could soon be powering laptops and printers via the humble USB port

In data transfer tech, the "superspeed" USB 3.0's 4.8Gbps can't match Thunderbolt's 10Gbps transfer speeds. What it does have is an impressive cheerleading squad including HP, Microsoft and Intel and big plans to power your gadgets.

By early 2012, USB 3.0 could be delivering up to 100 watts, more than enough to charge your netbook or laptop battery – Thunderbolt's limit is a whimper by comparison at just 10 watts. There has been no announcement as yet on faster speeds for USB 3.0 but if our gadgets are getting much needed juice at the same time, we might not be in such a hurry.
