This Is The World’s First Smart Charger That Automatically Turns Off When The Gadget Is Fully Charged

The Asmo Charger 5

We have all wondered this but never really seen anything happen in this regard until now; why can’t our smartphone chargers be smart as well? What we are trying to say is this; you put your cell phone on charging usually at night and it would be really nice if the charger would automatically switch off once the phone has been charged completely, no? Such a charger would prove to be environment friendly, energy efficient and hazard free. However, there has been no such charger, well until now. Say hello to the Asmo charger, which is basically the world’s first smart charger capable of cutting off electricity once the smartphone has been charged completely.The Asmo Charger 2

The gadget comes from a 33 year old I.T. engineer by the name of Asmo Saloranta who lives in Oulu, Finland. His inspiration for the gadget hit him when his fiancée, Johanna Papinaho, lost her childhood home to a fire that was started because a mobile charger was left plugged in. The Asmo charger takes care of this problem by automatically shutting down and isolating its connection from the electricity grid when the charging is complete or when you unplug the phone from it.The Asmo Charger 3 The Asmo Charger

In words of Saloranta; ‘I set myself a challenge to invent a charger that is much safer and consumes no standby power. Two years later, I came up with a solution. How it works is the power to the charger is limited and isolated from the grid – it’s a pulse of power that comes off the grid rather than a stream. The phone charger simply turns of the flow.’

The Asmo charger comes with a number of different connectors which also include the Apple 30-pin connector, the latest Lighting connector and even a micro USB. Users also have an option to either pledge for a US or EU two-prong plug on Kickstarter. A UK version of the gadget will be launched later this year.The Asmo Charger 4

Saloranta further said that; ‘It is really taking off now, I am now in talks with mobile phone manufacturers. ‘There have been so many tragic stories about phone chargers when they have been left on; I thought it was strange that nobody had done this. Johanna is definitely my driving force behind the project, her story helped me come up with the idea, and she is very passionate. Our mission is to make the world a better place. By leaving mobile phone chargers on, we use the equivalent of two nuclear power plants or 25,000 wind power mills.’

While this charger helps us become safer, it also works as an eye opener by helping us realize that how much of energy are we wasting by just keeping our chargers plugged in or keeping the switch turned on.

    i have an SM-T900 tablet that uses the USB type connection. Does your power cutoff unit have a USB type connection on it?

    Sadly, I just read that the company is no longer. This was, and still is a great idea.

    Hi, is there some way to go a step further and have the charger switch on and off at certain battery percentages? I heard that laptop battery life can be maximized if you only charge it between 30 and 80%.

      That is reasonably true, for Li batteries start to significantly lose ‘life-span’ if maintained at ‘full charge’ .. A chemical reaction occurs, ‘inspired’ by full charged voltage (and by heat!) that can drasticly decrease battery life : Eg, only charging to a max voltage of 90 percent can add a year or more to that bat’s lifespan ! …. if only to 80%, then the benefit can be 2 yrs or more!

    I think its a great invention. Where can I purchase one and at what price?

    Awesome.Actually I also got the same idea, while i use to stay in hostel it was very tough for me to switch off the charging of my mobile in night.This i took it as my mini project in my engineering course i also done a basic circuit for this however it has many limitations,but i am satisfied with this.
