Stopped working:
It sure looked promising, since I fly to Asia about five times a year. But after one successful use, it went totally dead.

Junk:
I really hoped this product worked despite the reviews. Well it doesn't. It will not charge any USB device and won't charge a 5th generation iPod. The only device it will sometimes work on is my iPod nano that doesn't need external power. I've never purchased anything that doesn't work.

Spare power made easy:
Kensington has thought this through - it is small, can be charged in several ways, has LEDs for checking status and supports the iPhone 3G. Not all similar products can support the iPhone - earlier this year I bought a similar (and larger) product from another maker but my new iPhone would not charge from it. I haven't yet used the Kensington Battery Pack enough to say how long it lasts or will last but it's great for cheap airline seats where there is no power available. The long cord seems awkward but makes it possible to keep the charger in a bag while you listen to music or watch videos.

Good product:
i like it because it is small, so it portable power. It also has an indicator so you know when you're running low on power and need to charge. I also like the product because it has an AC adaptor so if you don't have a computer or enough power to a computer you can charge is on a wall or AC adaptor.

Better, Not Best.:
Very useful & well made product but not as much reserve as the APC equivalent I ended up with. Tip: I velcro-ed the back of my power backup to my iPod Touch's leather case.
