The iGo everywhere85 is a great option for people who have lost their notebook power adaptor and are looking to replace it as well as for people who travel frequently and need an adaptor that can be plugged into the wall, airplane seat power, and into a car outlet. The iGo is able to power a laptop and one other device that takes less power at the same time. You purchase the adaptor you need separately from the charger. It is also convenient since it comes with a carrying case that can hold the charger, cord, and adaptors. Helps to keep your laptop case just a little bit neater and helps you to have fewer power cords to carry around.
