They state otherwise, but if you put it on when it's nearly dead, you can also start counting battery life from that moment.
In that case, their 800% increase can be true, 90 seconds instead of 10 seconds use.
Wytnucls:
The 800% extension is possible for a hypothetical device which cuts out near the 1.5V battery voltage.
I don't have such a device, but maybe there exists one in a dark corner of the world.

thanks for predicting this, it leaves me some time for thinking about:

-How to behave if I get this as a present from an illiterate.

Galenbo:
As many devices already have a boost converter inside, how do multiple stages of boost converters behave combined?

I have very bad expieriences with that (another tech field), especially when at least one isn't designed for it, and the load goes up and down.

Its still better than novelty socks - at least you can send it to Dave for a teardown.
