Performed as promised for a great price

I thought this was one of the best new items to come along in a while -- I have used it with my laptop in rental cars and on international flights, and not had any problem. Even in international rental cars. It's great because the shape is compact and overall size is small, so it's easy to pack -- especially these days, I'm trying to downsize all the gear I carry with me. Definately a great purchase in my book!

Bring a book just in case

I purchased this item to power my MacBook on airplanes. I had four long haul flights this month. Two 7 hour flights, and two 10 hour flights on United Boeing 777s. I could only get the Kensington Ultra Portable Inverter to work on the first flight out. On the others, as soon as I plugged the Inverter into the Empower recepticle, the Empower light would go off. When I pulled the Inverter out, the Empower light came back on. For what I bought it for, this product did not do its job.
