A Mumbai-based company has developed a
hand-powered charger for the electricity-deprived rural India.
The Roto Charger helps users tap power by either cranking or rolling the device any time they need to top up charge on their phone. A decade ago, India had less than 10 million telephones and the growth rate was meager. The country was heading towards a billion people, but had amongst the lowest tele-densities in the world. Now, India is the second largest telecom market in the world, thanks to the entry of
wireless communication devices such as cell phones with chargers.Even the villages of India are witnessing the urge to get connected to the rest of the world by possessing mobile phones
The Roto Charger helps users tap power by either
cranking or rolling the device any time they need
to top up charge on their phone or to survive it the next
hour or to make that last call. What differentiates the
Roto Charger from other similar charger is that the
user can charge the mobile phone in two ways, by
rolling the handle or by rolling the device on any
surface. “Not only in villages, our charger is
well-received in urban areas also. The small,
light-weight roto deviece is definitely a resource of power
for those who travel a lot. this is called rolling deviece or
roto charger because it is used through rolling it by fingers.
the roto charger costs at Rs 450, roto charger's environment-friendly
energy solution can be used even while talking by the
single hand rolling mode. The charger takes just one
minute of rolling to provide three minutes of talk
time and about 30 minutes of stand-by time. Also, it
is safe to use for the cell phone batteries. In fact, the
lower charging currents can lead to a better battery
life.
