content: Does this exist? I want one for some Sony noise canceling headphones. They use one AAA battery. The cut off voltage is quite high at about 1-1.2 volts. The 800% claim is hard to believe but it might help use more of the battery capacity.

content: Just a note that the battery indicator also won't work as the voltage will be fixed at 1.5V until the battery just dies suddenly. That is, if Batteriser ships...

content: Quote from: grifftech on March 23, 2016, 11:09:57 pmTo the best of my knowledge, the owner of the IGG campaign, Bob Roohparvar, has only shown prototypes of an AA sized unit. The AA sized unit is believed to work for low power devices, up to around 100mA, but is not practical for higher current drain devices.There was talk on the IGG campaign, of a custom IC, to increase the available current. There has been no evidence that this exists.The IGG campaign announced that the 'Perks' would be delivered in November 2015. It is now nearing the end of March with no firm commitment on a delivery date.I have built, what I believe to be a faithful representation, a clone of the Batterizer. My original prototypes were larger than the official Batteriser:See this message:https://www.eevblog.com/forum/projects/new-project-a-batterruser/msg739648/#msg739648These were featured in a video:AA sized BatteriserI later built an AA size Batteriser:https://www.eevblog.com/forum/blog/eevblog-751-how-to-debunk-a-product-(the-batteriser)/msg850492/#msg850492AAA size Batteriser CloneI have designed an AAA size Batteriser, but I have not built it. These are some of the pictures of the design:Link to the message:https://www.eevblog.com/forum/blog/eevblog-751-how-to-debunk-a-product-(the-batteriser)/msg879979/#msg879979I believe that it is possible to build an AAA Batteriser, but it will be limited to around a 150mA.Maximum Power TheoremThere is a fundamental limit on how much power that can be extracted from an alkaline cell.This is documented in this message:https://www.eevblog.com/forum/blog/eevblog-751-how-to-debunk-a-product-(the-batteriser)/msg809012/#msg809012So the short answer is that some from of boost converter is possible. It will not be as powerful as the Batteriser team claim. As time goes on there is increasing doubt that the Batteriser team will deliver anything.The aim of the Batteriser team is to sell the Batteriser company and or IP. As soon as they ship their claims, and hence the value of the company, will be destroyed.I hope this helps.Regards,Jay_Diddy_B
