A new Kickstarter campaign wants to put
the power of charge in the palm of your hand.
The
Mipwr Dynamo is an iPhone case with two functions: It acts as both a protective
shield and a charger for your phone — with no plugging in required.
When your phone's battery begins to
drain, you can easily pop out the concealed hand crank from the side of the
case and begin to power it back up. As you crank the lever, a charge is
generated.
The
Mipwr Dynamo works through electromagnetic
induction, which is the process of harnessing electricity using a magnetic
field. A magnet inside the case spins as you crank the handle, creating energy
that is transferred into voltage to juice up your phone's battery.
Using
electromagnetic induction is not a new concept. In fact, it's widely used in
all kinds of products today, from rice cookers to electric toothbrushes.
The
team behind the case told: “The magnet is generally encapsulated with coils of
wires to transfer this [electricity] to a battery storage device.”
According
to the team, a minute of pumping
will generate about 30 seconds of talk time.
