I needed to look for a new computer adapter as I am headed to Europe in a couple days and my current one is an older 3 prong grounded (the outlets out there only accept 2). While I was hunting around online, I found the Dell Slim Auto/Air Adapter. Not only does it have the 2 prong AC adapter I was looking for, but it can be converted to either a DC Car or a DC Airplane. This is super convenient for me since I’m going to be on the plane for at least 9 hours each way. Even with the extended battery I also purchased, I might need some additional power for my laptop. It also comes with a handy carrying case and an extension cord for the DCs as well. Since the adapter goes from 100-240 watts, I don’t need an extra converter. I only had to buy an additional European plug adapter that cost $4 at the travel store. The only bad thing I would have to say is that the AC cord is alot shorter than my original plug at only around 3 feet. (I’m not sure why they didn’t include an extension for both the AC and DC.)
I found the average price around $70-80, but luckily I was able to find a new one on eBay for only $40 (plus another $10 for shipping and handling).
