Now there are now a selection of battery chargers available - ones that carry
a charge (wireless) and are as tiny as a lipstick case, ones that need to be
connected into other energy and also chargers that are fairly large and power
entire networks.
Generally the bigger the charger the quicker the charge returns to the
accessory being charged. The small chargers do provide some emergency power but
many of them are not able to fully charge you mobile devices. The best choice
now is the medium-sized charger that plugs into AC or DC power.
The medium-sized chargers that must be plugged into a source of power has a
charge which varies from 3 volts - 5 volts depending on the location (less
amperage with the house or AC power). The house Output = DC 5.0V - 5.5V 500mA
and the car Output = DC 5.0V - 5.5gv 800mA. It must be kept in mind that these
chargers are designed to be used in the US, Canada or other countries that have
power of 110 watts or less (about 12 volts) Most mobile and electronic
applications require only 5 volts to charge. Your appliance will draw only the
amount of current it needs, so your appliances should be fine with these
chargers.They are not universal and cannot be used without an adapter in
countries like Thailand where the power sources are much higher.
However, there is a new charger yet ahead on the marketplace from an
18-year-old Indian-American science student who created a cellular phone charger
that charges in less than half a minute. In order to do this she customized a
supercapacitor "with increased energy density while maintaining power density
and long cycle life". Her name is Eesha Khare from Saratoga, California, and
she's headed to Harvard this autumn where she will continue her studies.
In the meantime prior to the time that Eesha's creation is available to
everyone for charging all mobile devices, it would be best to find a small
charger using AC or DC power. A brand-new type of cell phone battery charger is
now available that can be used in both the home or office but also the car when
travelling. This white, torpedo-shaped charger might not look like something as
helpful and sturdy as it is. Why would one want a charger for both the auto and
workplace? It's something that could always be carried with you to have ready
when needed.
There are a number of chargers that use USB plugs such as this one but few
that can be used in both the car and house. It's a good idea to try some of
these first before purchasing, but unfortunately, sometimes they will fail after
a period of use. It's best to find a reliable company that guarantees its
products and will replace any defective units.
