The advantage to iGo's Green Technology, as it calls its secret sauce, is that the iGo Green automatically shuts off - so laptops can be plugged in, but won't draw unnecessary energy once the laptop finishes charging or isn't on.
According to iGo, the iGo Green charger uses 80 percent less energy in stand-by mode. The charger comes with eight laptop tips for use with a variety of laptops from Asus, Dell, Fujitsu, HP, Lenovo, MSI, Sony, and others. These charger tips represent a new design for iGo; they're specially designed to measure out the energy allowed by the device that the tip is designed for.
Aesthetically, the iGo Green charger pleases as well. It measures just 16.5mm thick; this relatively flat and rectangular design makes it easy to stow alongside your laptop in your bag. It also has the USB charging port coming out of the same direction as the cable that goes to your laptop, a design that fixes the problem of the company's netbook charger (on that device, the USB cable awkwardly juts out of the side of the charger).
The charger works across worldwide voltages, but for now is strictly AC power. An AC/DC version that will include an auto /air adaptor is coming, according to iGo.
The iGo Green laptop charger delivers targeted power to almost any laptop from all over the world. With additional adaptors, it will charge mobile devices too. It's good looking and it should save money and resources by using power efficiently. It's clearly a very useful device, but at around £85, it's not cheap.
