The PowerCup kept my Kindle, phone and then laptop fully charged. Very Cool. Only disadvantage was that the cord is on the short side.

3.0 out of 5 stars Tight fit for plugs and lighter outlet May 10, 2011
By ShawnB
Size Name:200 Watt Cup|Amazon Verified Purchase
I was really excited about the concept and creativity of this device. It does what it says it will do and successfully charges whatever items you insert into it. Items plug into the USB port fine, however, you really have to apply pressure to put plugs in and pull them out, same for when you insert the device in your lighter outlet. I am worried that eventually something is going to get jammed or break off. So handle with care when using.

5.0 out of 5 stars Best $25 I've spent in awhile June 6, 2011
Size Name:200 Watt Cup
I was recently on a 10 hour road trip and used the Power Cup, it worked great. Both my wife and my laptops were connected to the Power Cup and we didn't have any issues. The fan does get a little loud, but not loud enough not return the Power Cup. I would strongly recommend this product.

I can use it to plug in anything that can be plugged into a wall outlet at home. No need for car chargers for phone, tablet, whatever. Just bring the regular cord.

1.0 out of 5 stars Terrible and Cheap
Bought this as a promotional item for $8 from another site. Fan ran and was somewhat noisy, but the stupid thing broke in less than 2 months. Very cheap. Read more
