I just wonder, if the video is part of a new, clever (or not) marketing strategy? At least at my computer (tried with two different browsers), the video stops after 17sec or so and is interrupted in midst of a sentence by a form to enter my email address. I just wanted to view the video to the end, but have to enter my email instead?? Either an error in the page (?) or a clever marketing strategy?? In my case, not so clever, because I will not adhere to such tactics. It could also be, that the whole thing is similar to that tactics? As jwf also pointed out, the claims are a little over the top. I don't think, that 800% are really achievable. Maybe 20-30% in real life applications. That of course could be still good, when the gadget will not be to costly and is unlimited reusable. Still the question remains, if simple rechargeable are not still better (for your economy and the environment) in cases where you have battery-intensive applications. I try to limit the usage of non-rechargeables to cases where the battery is swapped really seldom -- and in such cases, additional gadgets just make life more complicated.
