Coin based mobile phone charger for multiple phones
ABSTRACT:
The coin-based mobile battery charger developed in this paper
is
providing a unique service to the rural public where grid power
is not
available for partial/full daytime and a source of revenue for
site providers.
The coin-based mobile battery charger can be quickly and easily
installed
outside any business premises.
The mobile phone market is a vast industry, and has spread into
rural
areas as a essential means of communication. While the urban
population
use more sophisticated mobiles with good power batteries lasting
for
several days, the rural population buy the pre owned mobile
phones that
require charging frequently.
Many times battery becomes flat in the middle of
conversation
particularly at inconvenient times when access to a standard
charger isnt
possible. The coin-based mobile battery chargers are designed to
solve this
problem. The user has to plug the mobile phone into one of the
adapters and
insert a coin! the phone will then be given a micro-pulse for
charging. "t
does not bring a mobile from dead to fully charged state.
