As mentioned before, an increase by 800% would mean that only about 11% of the capacity would be used under normal conditions. Not taking into account efficiency etc. I guess it will be extremely difficult to find one case where this is the case.

And that's the kicker. No matter what battery you are talking about, or what product you are talking about, it all comes down to simple energy used vs energy stored in the battery.
That 800% must also include the efficiency of the converter!

Would such a converter achieve any significant gain for the user ? Simple technical considerations show that no, unless we talk about some very rare badly designed products. Therefore their claims are false and the end-users will never get what is advertised to them. This is the definition of a scam.

It is not a scam. It just the usual BS marketing numbers making the headlines, seen it countless times before in every industry, nothing new here.
Companies are free to use words like "up to" etc, and have no real requirement to tell you what average figures you might expect in practice. Welcome to the free market. Of course, if they can't show at least one case of x8 improvement, then they might have some explaining to do.

Grapsus:
Ok, let's call it BS marketing. But who are they trying to fool here ? The first disappointed customers will tell it everywhere and nobody will buy the thing ever again. Since their strategy cannot lead to a happy growing customer base, I wonder if the real goal is not about impressing investors in order to get a big founding round...

Typical ad hominem statement. Come up with real physics instead. All my posts are backed up by Duracell graphs and application notes. You obviously didn't bother to read or grasp any of it.

Ok, sorry, I might have  been carried away.

If that would be true, then there would not be any "snake oil" around.

How to profit from a silicon snake-oil gadget:

* Get it prominent in the media.
* Get it on the market in November.
* Get it in all the pre-Christmas gadget magazines and catalogs.
* Sell hundreds of thousands of units to non-techies looking for Christmas presents.
* Discount it heavily in the January sales to clear remaining stock.
* Fold the company 1st February before most dissatisfied customers have got round to returning it.
