The idea is cool...but having fast charger is better i think...if you'll charge for 5 hours, why not do it with regular 2500 mAh batteries using fast charger? besides, working with a laptop for five hours is a bit unbelievable coz no such laptop exist to last 5 hrs (except ultraportables).. Umm, if in case PC is used, why not use regular charger..a regular charger has more slots than your USB port..but nonetheless the idea is novel...
 
Those batteries do look pretty cool, it's a pity that they are not more economically priced.

They are a very good idea though and chances are more brands will begin selling similar typed batteries with faster charging times and even cheaper prices...
 
I never understood all these USB devices that work on USB instead of electricity, but they are COOOOOOOL :)
