Best iPhone Backup battery charger pack?

I found some Duracell backup packs at COSTCO: Two in a package for under $20. They use two AA batteries (first set included) and have a cord for iPhone and another for a Motorola-type mini-usb unit. Electronics boost the voltage from the series batteries to give the right charge voltage for an Li-Ion battery.

Here's a link to a descripton:

Ditto here on the Duracell packs.

Here's a link to the Kensington model:

It looks like a good device. Plus is that it has a built-in Li-Ion-Poly battery with more capacity than two Alkaline AAs. Downside is you must recharge it between uses (with the Duracell model, just put in a new pair of AAs).

Looking further there are some reviews here

which are not encouraging.

The Duracells have leads for iPods, iPhones, and other phones like Blackberrys.

I'm happy with the Duracell chargers. I have a couple, my wife has a one (Motorola RAZR), my daughter has one and my grandson has one. Not that we've needed them yet, but good to have them along.

We have tested to make sure they work with the 3GS.

Just bought this for mine, sits in the palm of your hand and works a treat!

Thanks for the info! Looks like a nice unit, and similar in design concept to the Kensington model. Apparently there are a variety of these rechargers -- which I didn't know until this thread.
