Just saw the ChargeTech battery pack (that the company is touting in their own reply in this thread as "highest crowdfunded battery pack of all time") on a "cool products" site.
They are charging $270 for this battery pack that seems to only be effective for mobile devices, for which a similar product is only $25.
What the f am I missing here, why is anyone actually buying from these people? You could buy a stack of extra laptop batteries for the same price.
