Bought this because I didn't want to phone dell support when my Dell Mini 10 charger broke (didn't want to spend ages on the phone to then wait a week for delivery).
Does exactly what it says on the tin - works fine, almost identical to the one it replaced except that general build quality seems better, and it even has an LED at the end you plug into the laptop to show if it is plugged into the mains or not. Simple idea but a damn good one.
As with my original charger and in the product image, it does not have a bulky power-pack thing - it is simply a mains plug with a single wire that connects to the laptop/netbook.
Thank you seller for saving me valuable time :)
I can't say whether or not this works with the other laptop models specified but it worked on my Mini 10.
Hope my review helped :) if so then rep it!
