USB to Deliver Up to 100W of Power to Your Devices
USB charging has become a necessity amongst the gadget-carrying folks of the 21st century, and even more so in the near future, now that the 100W Power Delivery spec has been approved for both USB 2.0 and 3.0. This upgrade should allow for future power-hungry devices (including a laptop) to be readily charged over USB. Unfortunately, only future hardware will be compatible with the new power spec, although the technology behind it promises to be flexible in terms of charging devices. To get the maximum 100W juice high-powered USB cables are a prerequisite, but older cables can still be used as voltages will be automatically checked and adjusted based on the capabilities of the wires and the plugged devices. Brilliant, as this should help reduce issues arising from USB charging, and give the added convenience of using lesser cables to bring while travelling.
