How does it power a laptop exactly? Can I plug the laptop charger into it somehow, or is there a special adapter I'd need to power my dell?

I would like clarification on the question regarding how long the device "holds" it charge and be available to charge my phone. If I am understanding correctly, if I charge the device and leave my house house at noon, it will be "out of juice" and unable to charge my phone by 2:00-3:00pm (depending on whether I am using a singular or dual USB), even if I havent used the device to charge anything during those 2-3 hours? If that is the case it doesnt seem to be very useful as my phone battery usually lasts longer than that with regular use (ie: phone calls, texts, photos, etc).

Once I plug the USB Charger into a dead cell phone or laptop computer how long does it take to transfer power or is it instantanious meaning I would be able to use the dead cell phone or laptop computer immediately? Also, how many times can the USB Charger be used before it needs to be re-charged and is there an indicator light (meter) on the USB Charger with lets me know how much power is remaining?

I see that you said the charger will only last 2 hours for the dual if it is fully charged and just sitting in a purse and not being used. So how is this product supposed to give us 30 hours of charge if it only lasts for 2 hours? I have an iPhone 4s, a Zune, and hp laptop and this product sounds great for traveling on a plane, but I need something that's going to last a long time for trips.
