As the number of electronic devices we carry around with us at any given moment has increased quite sharply over the past few years, the danger of any or every such product running out of batteries exactly when we need them most is ever more present. And this is exactly the reason why the Kensington company launched back in the second half of 2007 the Wall/Auto/Air Notebook Power Adapter with USB Power Port, a device that allows users to charge their portable devices wherever there's a power source at hand (regardless of the type of said power source).



Thus, the power adapter sports a built-in USB power port that can be used for charging cell phones, PDAs, the iPod and a whole range of other devices, due to the fact that it's compatible with all the USB power tips provided by Kensington. Moreover, the device works with several laptop models, including here those coming from Dell, HP, Compaq, IBM, Lenovo, Toshiba, Sony, Gateway and Acer, due to the fact that it comes packed with a series of color-coded tips, which make the setup operations a lot easier.



Another important selling point of the power adapter from Kensington is the fact that it works just about anywhere around the world, due to the fact that it's completely compatible with the Kensington Travel Plug Adapter (unfortunately, available separately). Moreover, the device assures an extra-level of protection for the devices it's connected to, as it provides over current protection, over voltage protection, over temperature protection and short-circuit protection features.



The device supports inputs of 100 – 240VAC, 50 – 60Hz, 1.5A Max and can output 14 – 17 VDC and 17 – 21VDC (Notebook Voltages) at 90 watts. Moreover, since it's supposed to be a portable device, it's quite small and lightweight, measuring around 155mm (6.1 inches) x 65mm (2.6 inches) x 30mm (1.2 inches), at a weight of around 550g (body) or 710g (ready to use).



The Kensington Wall/Auto/Air Notebook Power Adapter with USB Power Port retails for around 140 US dollars, which a pretty fair price to pay for such a device, taking into consideration the level of charging versatility it provides.
