Customer Reviews

Best accessory for my iPhone!
This has been the best accessory that I've bought for my iPhone so far.

I took it on a short business trip to Europe. Not only was I able to use it to recharge my iPhone from ZERO to FULL on the plane and train (ie. Eurostar), but my husband discovered the included mini usb cable can recharge his BlackBerry as well. So we are able to share this one device for several of ours.

On top of that, the package included an iPhone sync cable. You can never have enough of these!

Good power backup for an iPhone or iPod
I have an iPhone 3G which needs to be recharged just about every day that it's used. That can be a challenge when I'm traveling, although if I have a laptop it's possible to recharge the iPhone via the laptop's USB port -- as long as the laptop has enough power to spare. The Kensington set is a good backup. It will fully charge a nearly exhausted iPhone battery in an hour or less. You can use the phone while you're charging it (although that means you'll use some of the stored power). The battery has a button that lights up a set of LEDs to show you how fully charged it is. It comes with both a wall plug and a USB cable. It's small enough to carry in a pants pocket. You also have to carry the included cable to connect it to the iPhoe or iPod. You could carry the whole set - battery, wall adapter and two cables -- in a jacket pocket.

The only thing that's missing is a case or bag with a drawstring. One or the other would be very helpful for storing the two cables, the wall adapter and the battery itself.

You may not get exactly what you ordered, but don't blame Amazon
The Kensington battery Amazon is selling is model K33396US. Amazon just shipped me the K38021/K33396, but the packaging still has K33396US printed on it. Why is this important? The K33396US has a battery charger designed for travel abroad. It has two European style plug adaptors that slip into the battery charger. The K38021/K33396 has a fixed battery charger with a US only plug.

I think Kensington decided to save a few pennies by reducing the product's capabilities and then saved even more money by not changing the packaging or UPC. But not telling Amazon to update the model number on their product page? Not nice!
