Macsense Just Mobile Gum Pro Mobile Battery Pack, 4400mAh High-Power, for iPhone/iPod

I use the Gum Pro as an outboard battery for my Zoom H4n and Zoom Q3. The Zoom Q3 without the Gum Pro uses up it's AA batteries in under an hour. Yesterday with the Gum Pro, I ran it continuously for three hours, and still had 33% charge left. The Gum Pro is so compact that I can slip it in a shirt pocket while I use the hand held Q3. Only problem, is it was a little difficult to find a USB to DC male plug adapter that fits the Q3, but luckily I had one tucked away. I hope the company will make one available as an option.

Bought this for an upcoming trip to NYC. Considering the power drain when using the iPhone, I determined that I'd need extra power for my trip. This is an excellent, essential accessory for the iPhone, considering that I get 2-3 charges for the phone per battery pack charge. I absolutely recommend this for your iPhone, and other gadgets that need extra power supply.
