Two inventors from Illinois have created a special case that slides onto an iPhone battery allowing it to be charged by squeezing the device in your hand.
Mipwr Dynamo attaches to the battery’s charging point and not only stores two hours of energy to be used when needed but also contains a lever that generates electricity when squeezed, Daily Mail reports.
Designers Bob Panos and Karl Lee say that each minute of squeezing gives the phone 30 extra seconds of power.
The two have set up a Kickstarter campaign to fund the production of their invention.
“After witnessing the aftermath of power outages from recent natural disasters, such as Hurricane Sandy and the cruise ship disasters, we thought about taking an existing technology (electromagnetic induction), and making it small enough to fit in the back of a cell phone case.”
“We thought, ‘how cool would it be to have an alternative energy source, besides a backup battery that could power a mobile device, so users could send out a message or phone call when they need to most?’“
According to Daily Mail, the top of the case comes off and the iPhone case then slides into the bottom, connecting to the charging point of the phone’s battery.
There’s also a battery inside the case that can be charged by plugging into an outlet. When connected, this battery charges the case and the phone battery at the same time.
If the phone is removed from charge, the case can be used as a backup battery by switching a lever on its side.
The phone then exchanges its own energy for the energy stored inside the case.
Once this energy is depleted, the lever can be switched from inside the case and squeezed to generate more power.
From the Kickstarter campaign:
“In the event you exhaust both the phone battery and Mipwr’s backup battery – that will give you two extra hours of talk time – you can pump the push lever to produce 30 seconds of talk or text time for 1 minute of pumping.”
“These efforts will create enough battery power to make a distress call or text at a moment’s notice.”
The first set of cases will be available for the iPhone 4, 4S and 5.
Panos and Lee are reportedly asking for $78,000 in funding to take their project to the next level.
If the funds are met, the cases will cost $25.
