It Betteridge! Jon Phillips reports on the Batteriser, a metal sleeve promising "up to" 8X more life from disposable batteries.
It’s essentially a voltage booster that sucks every last drop of useable energy from ostensibly spent batteries. So, instead of using just 20 percent of all the power hidden inside of your Duracells and Energizers, Batteriser makes effective use of the remaining 80 percent. Voltage boosters are nothing new, but Batteriser scales down the technology to the point where it can fit inside a stainless steel sleeve less than 0.1 mm thick. Roohparvar says the sleeves are thin enough to fit inside almost every battery compartment imaginable, and the combined package can extend battery life between 4.9x for devices like remote controls and 9.1x for various electronic toys.
Here's the published patent application, which is not a patent.
Red flag: Phillips writes that the creator proved he wasn't selling snake oil by demonstrating the gadget for him, but there's no description of independent testing. Did the guy just play with it in front of you? Who provided the batteries? What were the test controls? Boosting voltage at the expense of amperage and getting 800% more operational time, really? Turned down VC because the "money trail" led to battery companies, in favor of Indiegogo? Consumers with mountains of nearly-dead alkaline batteries want to know!
Batteries have always been a barrier in the evolution and adoption in soft, wearable devices. You wouldn’t want the chemicals inside batteries to leak out onto your skin and ideally there wouldn’t be a big risk of them bursting into flames either. Stanford engineers have developed a new kind of solid polymer battery that can […]
This PulseTech charger, and responsible behavior, has changed my life. I used to kill the batteries in my cars and motorcycles on an almost annual basis. I would intend to ride the bike more, but it’d be rainy. I would keep telling myself to take the Vanagon out but it was parked behind my daily […]
As a method of testing battery output, it seems a bit elaborate, but racing AAs down coiled copper tubes looks like a lot of fun. Mr. Michal: Duracell, Varta or Energizer, Which Will Be the Best? In this video you’ll see two races between aa batteries. Infinite loop and DRAG RACE. How to make the […]
For wine lovers around the world, it’s all about discovery. Once they get a taste for the grape, oenophiles are rarely satisfied with even the most carefully curated, go-to vintages. There’s always a hunt for the next great pairing, the thrill of uncorking a bold new Tempranillo or sublime Moscato. That feeling is a jones […]
These toys and games can keep the kids busy while you’re all trapped inside. As rough as all this time cooped up inside the house is on us adults, it’s even worse for kids. All that borderline maniacal energy along with an unquenchable thirst for stimulation and attention make home sequestration like a life sentence […]
Python is everywhere. Just look under the hood of virtually every major tech player of the 21st century and you’re likely to find a whole lot of Python-based coding language staring back at you. Case in point: Netflix. You may not know it, but from its security protocols to its much-hyped recommendations, it turns out […]
