5.0 out of 5 stars Best Portable Battery for Iphone/ITouch/Classic There Is, April 5, 2009

I've lost track of the number of portable chargers I've purchased for my Iphone 3G/Itouch 1G/Ipod Classic 160Gb that have been worthless. I came across this unit and told myself "If this doesn't work, I just give up!" Got it home, let it fully charge off my my PC's USB port, then gave it a try. It WORKS!! I can get between 3-5 charges off of it before needing to recharge the unit. Best out there.

5.0 out of 5 stars Just Mobil Gum Pro - best iphone, ipod & mp3 battery back-up & charger, June 13, 2009

This has far more power (4400 mAh) of any charger - enough to fully recharge my iphone 3g more than three times. It is not large or heavy - easy to carry around - fits in the palm of my hand and has smooth rounded corners that make it comfortable to grasp. It is about 3/4 the length of a credit card and about the same thickness as the width of my index finger.

It can also charge any mini-usb mp3 player or device with the included cable (usb to mini-usb) that it comes with (same cable that it charges with.) It does not come with an iphone / ipod cable.

Since it is so small and light, I find this a much better solution than having a one piece battery pack always attached to the iphone, making the iphone uncomfortably bulky during use. I much prefer to keep the Gum Pro and a cable in my pocket to charge or use only when needed. Of course on a plane or in the car, just stow it on your lap or in the seat pocket.

Can't beat the $60 price for the power and convenience. For $7.60 expedited shipping, Amazon vendor Macsense had it from California to my mailbox in Connecticut 3 days after I ordered it.

I couldn't be happier with this.

I got my battery pack about a week ago, and have used it a couple of times. The first time was when I was laying in bed reading an eBook with Stanza, and got the 10% remaining iPod battery alert. I plugged in the Gum battery pack, and continued reading while the iPod battery recharged. The iPod battery charged to full bars, and there was still 3 bars left on the Gum Pro battery pack.

The only negative comment I have is that the detents for the on/off switch are weak/nonexistent, so the battery pack can turn itself on/off by accident. I suspect the switch on mine is defective in terms of the 'clicking' on and off, but the actual switching of electricity works fine. Not worth sending it off to get it replaced unless the electrical switch itself fails.

Overall, I've been very pleased with the Gum Pro. It's super-high capacity, and yet compact.
