--- Quote from: Grapsus on June 06, 2015, 04:13:01 pm ---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...

I get the feeling it's the electronics equivalent of ab-ductors, magnetic bracelets, cervical pillows, etc.

Get in there, sell the first few million as fast as possible, pocket the profit, close the company, start a new one with a different name...lather, rinse, repeat. Whoever does it first/most often gets the most money.

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.

Hello there,

That's the thing that bothers me the most.  Since the percentage is just the total energy divided by the used energy, all we have to do is choose the voltage cutout threshold we want and we can claim 800 percent, 8000 percent, you name it :-)

To the other poster:
I think that negative publicity only works for actors, not for electronic products.
Everything in this thread is well deserved negative publicity.

So my camera eats a new battery every eight minutes.

I put this on a dead battery get an hour of run time?

That's what they're saying right?

--- End quote ---

'selected' is a loaded word. I would say in 'some' cases.



--- Quote from: 0xdeadbeef on June 06, 2015, 01:05:16 pm ---Then again the nominal voltage of a fresh alkaline cell is 1.5 V and this is exactly the voltage that this batteriser is said to deliver over the whole lifetime.
So in  cases where the higher voltage means higher losses, this device extends the issue over the whole lifetime.

I don't know what exactly this product does but maintaining a let's say 1.2V level throughout the life of the battery may save energy also during the high voltage period.

'Consumed' is different that 'needed'. Ideally the device should spread the charge to provide the 'needed' power for as long as possible.  I don't think the video touched on that aspect.

Which would however help to participate in a discussion about this very product.

But this is quite the opposite of what it does. If you would have taken the time to either watch Dave's rant or visit their webpage, you would have found out that they argue that "most/all" devices don't work after a level of 1.3V. Therefore this things boosts up the voltage to 1.5V.

Why would it? It's a simple boost converter with a fixed 1.5V output. What you imply is that the thing magically knows what would be the best voltage level for the device you put it in. Even if this would be possible in theory, it's definitely nothing to expect from a $2.50 device that fits on top of an AA battery.
