Yeah, and if it was legit it would be so easy for them to prove it, just send out a device for testing. I would happily think it's a success if it gives only 25% extra battery-life (in most devices)! (But the typical scammer response to this is that they can't because then you will steal their trade secrets...)
They claim on their Facebook page they will release the data and prove their claims.
They claim they are still compiling the data. So they've spent several years developing this, patents applications, are rpactically on the verge of selling production ready parts, have had countless time and energy to produce slick marketign campaign, but they haven't been able to compile data that proves beyond doubt that their product actually works as well as claimed?
Skeptical engineers like us are very easy to shut up, just show us the data that proves it and we'll happily admit we were wrong and that this is the best thing since sliced bread.
Yes, they seem to be arguing the 1.4V cutoff voltage refers to unloaded battery voltage, but then the claim of 80% wasted energy makes no sense, just proves you were right.
That's the only conclusion any engineer can too, they are measuring the unloaded battery voltage. In whcih case they aren't taking into account the ESR during operation, and it's a fundamentally wrong way to measure battery voltage for remaining capacity calculations.
They are running out of legs to stand on.
