Let’s face it, the iPhone’s battery sucks.  With 3G, apps and email running, it loses it charge very quickly. I’m charging my iPhone at least once a day, and there’s nothing more annoying than seeing that ‘10% Battery Left.’ message. If this sounds like you, then you need the Kensington Backup Battery!

The battery is about 1/4 of the size of the iPhone 3G and is very light. This means its great for just chucking in your messenger bag or backpack. The battery comes with a retractable mini usb charger, and a cap to protect the top of the battery. Charging the battery takes between 1-2 hours, and will charge your phone in less that 45 minutes. The battery itself has no on off button which is very nice feature. This means you never have to worry about leaving it on. It has 4 LED’s to let you no how much power you have and when your charging the battery its self. Unlike many other batteries on the market this is very sturdy, and will not come out of your phone or ipod if shaken. I would highly recommend buying this product. Even if, at the moment, you think you won’t use it, you will find yourself using it frequently
