This Targus 90 Watt Laptop Charger is just what it says. It comes with multiple attachments so that it can charge many different brands of laptops. I thought that this is a great idea, I've been to many a meeting and/or class where the presenter ended up having forgotten the charger and there's not enough battery life to get through the presentation, sometimes that presenter has been me. I found that the seven supplied tips are the latest models, so if you have an older laptop, or an Apple, the supplied connectors won't work. Targus has thought of that as well and offers additional tips, just call their toll free number and they will get you the tip you need. Another nice feature is the ability to charge an additional USB device at the same time. This is not an exciting product, just one that makes sense.
