The biggest issue will be that it simply doesn't work as claimed.
Well it does, but you have to decode the marketing B.S. from their claims.
What they are saying is that the Batteriser can tap into the 80% of energy (or voltage using their parlance) still left in alkaline batteries that are thrown away. Sounds great until you read this paper that they threw at us:
http://www2.ife.ee.ethz.ch/~rolfz/batak/ICBR2003_Zinniker.pdfthat does actually claim that SOME batteries contain over 80% of usuable energy left (and actually using accepted scientific principles)
of course they fail to mention the conclusions reached in this paper about WHY practically new batteries are thrown out which have nothing to do with monkeys failing to clap or GPS units screens' dimming.So technically speaking, using the Batteriser can help you tap into this 80% of remaining energy. Hell, not sure why they said 80%, the Zinniker paper found that 10% of the batteries in the study had 103% of energy left in them, which by Batteriser standards comprises a "significant" number (you'll have to read the paper for an explanation of why it's >100%)
Of course not doing anything other than taking that recycled battery and sticking it into a TV remote or even a clapping monkey can also help you tap into this 80% of remaining energy. But that's not the point. Batteroo is not obligated to tell you that.
Forget the talk about miniaturization and boost converter efficiency and the size of their inductor and whether 0.1mm clearance is enough...they could build a simple battery sleeve and nothing more and it would still meet their claim on the Indiegogo page, about 20% of the time if you get your batteries out of recycle bins in Switzerland from the year 2002.
Hold the presses!I just went to Rolf Zinniker's site and while I don't speak German (so I have no idea what this is referring to), he's got this image on his site:
WTF is it with these battery guys and monkeys? Seriously! Dave, are you SURE that the proper way to test a battery is NOT with a clapping monkey?
