Google Inc has plunged into the smart phone market with a bang, this time heralding a new set of smart phone software apps. Apart from their hugely successful web email service, Gmail, Google has of late been developing its own phone operating system running on phones – Android. And, beginning late April 2011, Google introduced video and voice chat running on Android. What this means is that a user with a phone running on Android can now take advantage of the ubiquitous Wi-Fi, 4G and 3G networks and place calls via Google Talk. This extends to users on Gmail chat as active on their personal computers.

The devices that are currently supporting this video call service include the Samsung Nexus S range of smart phones. To successfully run video chat rooms on these smart phones, however, you will need at least Android Version 2.3.4, also called Gingerbread.

For you to be able to place a video call with your colleague or family you must be logged in into your Gmail account. The video calls are easy to locate as they are indicated on the smart phone screen next to the friend (contact) list. With video calls via Google Talk on an Android system, you could be chatting via instant messaging while at the same time having a face to face discussion with the guy at the end. All that will happen is that the instant message gets on the video screen to catch your attention. The video is automatically paused when the caller switches to another function on the smart phone, for instance opening another application or menu. This however does not put the voice on pause mode. This is advantageous because it lets you continue with the real time discussion.

Video calls require a relatively fast computer processor that will support the data as well as voice and video requirements. Android’s integration of audio, text and video chatting makes the platform a strong proposition among executives and other potential buyers who are looking at a differently styled and powered phone.

The integration of Google Talk technology on an easily updatable operating system that is Android brings you free phone and video calls wherever you are. It is thus an ingenious way of connecting you with the people who matter in your life, for a pittance. In addition, it is just a straightforward chat platform that will not only let you create an innovative way of communicating on the cheap but also makes it easy to do so. With just a few taps, you are good to go.

Since the software comes pre-installed there are really no hassles of extra downloading, sign up processes or hidden costs attached to the service. However, Google has not yet delimited the service from being an Android-only, exclusive affair much like Apple’s FaceTime and it still is not possible at the moment to place video calls on non-Android, usually iOS-run machines.

Google has a great idea and is catching up. It is worth a try.

If you are planning to buy a solar cell phone charger then it will be a good idea to look into the basics of this equipment. This will help you to find the right device for your cell phones and any other portable devices you may want to charge.

What You Want?

It’s important to first decide on the type of solar cell phone charger you want.Are you addicted to your phone? Does the battery last very long? How often does it normally have to be recharged? How well could you cope without it? Many solar chargers need direct sunlight to work. Others can cope with cloudy days or diffuse light. What you need depends on where you live.

The next step will be to find the charge required by your cell phone battery. It is usually only a few volts. You can use a solar cell phone charger of 12 volts or higher for this purpose. Some chargers come with up to 48 volts of power and you can use them for charging other devices such as laptops and media players as well as your cell phone.

Battery Power

Another way of dealing with the wattage is to look at the battery. Solar chargers usually use NimH or Li-ion batteries. These batteries have the potential of losing their power if voltage control tools are not put into place. Under this scenario, batteries can heat up and provide reduced voltage to the battery. It is therefore better to purchase equipment that comes with smarter controls where a steady voltage is maintained.

Working Temperature

It is equally important to find a charger that could harvest energy at lower temperature and sunlight levels if you live in the north. An ideal temperature range will be between 50F and 110F. This will allow you to use the device under different temperature zones without worrying about the lack of power generation.

Charging Time

It should not take more than a few hours to charge a phone on a solar-powered device. Some chargers can reduce the threshold to 3 hours while others may take 6 hours or longer. You can use this information to purchase a charger that offers exactly what you need.

Type of Solar Panels Used

The quality and durability of solar panels in a charger will determine its real worth. Monocrystalline and polycrystalline silicone crystals offer the best harvesting efficiency and seem to last longer. You can use these panels for up to 10 years if they are looked after, much longer than the phone is likely to last anyway. Amorphous panels don’t last that long but are available at lower prices.

Components

You will find these basic components along with a solar cell phone charger.

  • Batteries
  • USB cable
  • AC adapter
  • Connector

You can use the above pointers to purchase a solar cell phone charger with the best features and specifications for the money. It’s also useful to make sure you get the one you need, not just the one you want.
