Heavy Duty Laptop Battery Chargers

The first portable computer was known as Osbone 1 which was developed in 1981.

This heavy and cumbersome machine used CP/M operating system which means Control program monitor who was commonly used in 1970s before the MS-DOS wiped it out after the introduction of the IBM PC in the year 1981.

Finally professionals were able to move around with their data and information on a portable computer. The only problem was that it had to be plugged on an electric socket since it could not use batteries.

Kypro 11 was developed as perfection rather than a competitor of Osbone 1. It had twice the size of Osbone 1 when it came to the screen features and when purchased new, it came with a software bundle and it had twice the storage capacity and double density floppy drives as opposed to that of Osbone 1.

Next in line came the Bondwell 2 which was not released until 1985 which came as a result of the operating system decline of CP/M. The Compaq was introduced in 1983 at a time when standard computer platform was looked upon IBM Personal Computer.

Other laptop models that followed Epson PX-4, the NEC PC 8401A,PX-8 and NEC PC-8500. None of these four units came with standard hard disk or floppy although they made use of the CP/M modified system in the Rom.

On November 2005 the then UN Secretary General together with Nicholas Negroponte unveiled a rough prototype of the laptop computer.

When it comes to the choice of a good laptop battery charger, culpability is a factor that should highly be considered when purchasing a laptop battery charger.

It is always advisable to check on the user manual to ensure the necessary specifications have been followed in order to avoid purchasing a charger that might damage the computer battery.

It is important to go for the best quality because the charger immediately becomes part and parcel of the laptop just the same as the battery.

There are several types of laptop battery chargers and one of them is the solar charger which basically converts the energy got from the sun into electric energy through a process known as the photovoltaic effect.

The solar chargers are preferable because they are environmental friendly because when they recharge the batteries then the batteries can not contribute to the land fills.

Therefore be sure to go for a quality laptop battery charger.

1) 1.5" thick- YA that's right it is about the same thickness as a deck of cards! The reason for this is because this new generation uses LED's instead of LCD or Plasma so there is no need for light bulbs in this one.

2) Super COOL- The samsung UN55B8000 55-Inch 1080p 240Hz LED HDTV not only looks cool but it actually STAYS cool. Because it doesn't use Cold Cathode Fluorescent Lamps (those are light bulbs for us simple folk) that means that it doesn't heat up at all.

3) 240 hz refresh rate- Most TV's refresh in the 60hz-120 hz range so the images get blurred more easily. With 240 hz fast motion images appear ridiculously clear.

4) Energy Efficient- The samsung UN55B8000 55-Inch 1080p 240Hz LED HDTV is almost 40% more energy efficient than standard LCD and Plasma HDTV's. This is again due to the revolutionary LED technology that does not use light bulbs.

LCD TVs Are Fast Becoming the TV Standard

If you look around, you can easily see LCD technology. From the digital clock that beeps away at you in the morning to the microwave that served up your last late night snack, you have been utilizing LCD technology for years, most likely without even being aware of it. The digital watch on your wrist, the laptop at your office, even the MP3 player in your gym bag makes use of LCD innovations.

These are only a couple of examples of everyday electronics that use LCD technology. The most trendy and frequent use of LCD technology nowadays is the ever popular LCD television.

Liquid Crystal Displays or LCD TVs are those that use flat, thin displays made up of a series of monochrome pixels that are in turn displayed in front of a reflector or other source of light. That is where the image display comes from. In most cases, the technology used is that of the Thin Film Transistor or TFT that is a specific type of field effect transistor made by layering thin films intended for metal contacts along with dielectric and semiconductor layers. As such, the LCD television is more different than other image producing technologies such as a plasma display or older cathode ray tubes.

At one time, the general consensus was that LCD technology was only good when used on televisions of smaller size and that it could not contend with plasma technology when it came to larger screen sizes. With the advent of seventh generation panels by such giants as samsung, Sony, Westinghouse Digital, Sharp and LG Philips, those beliefs have proven to be false.

In October of 2004, LCD screen sizes where as large as 45 inches and were readily accessible by several companies and the Sharp Corporation took center lead with the introduction of the first 65 inch panel TV in history. By 2006, LG Philips had introduced the largest display yet with their 100 inch LCD television.

Today's LCD TVs are universal, in that they include a multi system tuner that displays NTSC, SECAM and PAL standards. They also offer electronic transformers that automatically use 110/250 voltage without any issues, as well as universal grounded adapter plugs. Also, LCD televisions are not going to be limited to the living room and now serve as computer monitors across the world.

According to recent news, manufacturers continue with plans to invest obscene amounts of money on the production and development of LCD television technology for a long time. It is highly un-likely that LCD technology is going anywhere, in fact, if recent trends continue for LCD TVs, then better advancements are yet to come!

The Samsung UN55B8000 - Energy Saving Big Screen Television

This is the third in a series of reviews based on the new range of LED televisions recently released by samsung. Like I mentioned in the two previous reviews, LED technology allows flat screen televisions to save up to 40% on their electricity consumption. There has been a large backlash from environmental groups at the increased use of LCD and plasma televisions, because in many cases they use more electricity than the old cathode ray type televisions we used in the past. LED technology hopes to redress this balance and is likely to become the de facto screen technology for manufacturers in the years to come.

samsung UN55B8000 - 55 inches of Perfect Picture Quality?

The UN55B8000 shares a number of features with its smaller cousins - the UN46B6000 and UN46B8000, what sets it apart is its huge screen. LED technology already adds to the viewing experience, but to see this applied to a larger screen, really highlights how much better these LED screens appear.

The addition of samsung's picture technology - Auto Motion Plus 240Hz, also helps to enhance this experience by analyzing every frame and adjusting it if there is the appearance of blur. This makes sports programming come to life - not quite as good as actually being inside the stadium, but not far off!

The UN55B8000 is also great for gamers. Its huge, crisp, color enhanced LED screen brings gaming to life and enhances the experience. The addition of 4 HDMI ports means that there is no shortage of ways to connect your games console or other peripherals.

Samsung UN55B8000 worth the expense?

There is no doubting that the Samsung UN55B8000 is not the cheapest flat screen television out there. However, in terms of value for money it offers a number of advantages over cheaper rivals. Firstly, you get a fantastic cutting edge design - the screen is super sleek at only 1.5 inch wide. You get a picture quality that could be argued as amongst the best in the world.

The LED technology helps the environment as well as saving you money on your electricity bill, and it will also future proof your investment, as LED technology is likely to render LCD and plasma technology obsolete over the next few years. However, the main reason to buy this TV is you get 55 inches of near picture perfect quality that makes watching any film or television programme an awesome visual experience.

How to Save Money When Buying Brother Ink Cartridges

Brother printers are one of the most cost effective printers currently on the market due to a number of key factors. First and foremost all new Brother Inkjet Printers use a separate ink tank system which offers the following benefits:

•Cartridges are predominately un-chipped resulting in the printer using all of the ink in the cartridge rather than running out after a specified number of pages.

•Individual colours can be replaced as they run out rather than a tri-colour system which requires the entire cartridge to be changed whenever one colour runs out.

•The cartridges are relatively large compared with competitors' offerings; for example a LC1100 cartridge contains 20.5ml meaning a full set of four collectively contains a massive 82ml.

•As the print head is actually inside the printer itself, you only ever replace the ink tank rather than the entire printing mechanism every time. This results in lower buying costs for both original and compatible products.

Because of the simple nature of the printer cartridges it is possible for companies other than Brother to create compatible ink cartridges which are sufficiently different to the originals to remain legal while offering lower printing costs. Customers looking to save money may benefit from using these compatible cartridges to reduce their printing costs. A compatible cartridge is a brand new alternative to the original cartridge and should offer improved cost per page prints without sacrificing print quality.

Brother Laser Printers also remain one of the most cost effective options on the market, again due primarily to the reasonable cost of both original and remanufactured cartridges coupled with a relatively high page yield per unit. A Brother TN135 cartridge for example will produce 5,000 pages out of the black and 4,000 pages per colour which compares favourably with a HP CB540 series cartridge which will produce 2,200 pages out of the black and 1,400 pages per colour.

An alternative for those looking to save money on their printing costs is to start using remanufactured toner cartridges. These units are original Brother toner cartridges which have been fully used then taken back to a recycling facility where any worn parts are replaced then the cartridge is refilled and tested before being boxed up and sold as a remanufactured product. These cartridges offer significant cost and environmental savings without sacrificing print quality.

Canon Powershot SX10IS 10MP Digital Camera - Does it Measure Up?

If you are looking to buy a Canon Powershot SX10IS 10MP Digital Camera with 20x Wide Angle Optical Image Stabilized Zoom then you have arrived at the right place, you will not get all the fluff, that the normal review sites, will give you. You will get research based upon extensive user feedback from the people who have actually used and abused this product, that coupled with a genuine rating of whether we consider the product to be worthy of the purchase price. I will try and point out, what was considered to be whats good about this product and what was not so good, based upon real people with no axes to grind...

Pros

First off the camera felt very solidly built, if not a little heavy for a point and shoot model, but it did however feel well balanced throughout.

The SX10 IS stood up adequately to heavy usage, giving no issues, the controls are intuitively placed also. The 2.5" LCD screen is standard, but if I am honest, I would like to have seen a 3" screen for that little extra, and of course you would expect for the screen to pivot for easy viewing of subject (self portrait for example). What was very useful was the speed at which the unit booted up and was ready to shoot and it was also mentioned how useful the low battery warning was utilized, surprising how often , you can get caught out. As for the picture, well the 20x Optical zoom was considered more than acceptable. especially when used in conjunction with image stabilization function, that I know is available on less expensive Canon products, namely the Canon 1100 IS 8MP.

Cons

The feedback was less enthusiastic with the lack of grip on this unit, very slippery in damp conditions, which doesn't help if the subject is moving. Although the controls are intuitive the menu is far from that, proving a little messy, when it was un-familiar. The built in flash is pretty poor, but OK for day to day use, or in emergencies, this will often depend upon your own needs and wants. Pictures taken in low light, could be better, this is because of the densely packed pixels on the sensor, any ISO over 200/400 is un-usable.

Our Research on the Canon Powershot SX10 IS 10mp Digital Camera Suggests:

This product is proving to be a worthy successor to the S-series and G-series before that, it appears to have taken the minor concerns with those previous models and improved upon them, however as a result, it has a few concerns of its own, that you might find disappointing. If I were looking for a digital camera with excellent viewing Verdict: If you are looking for a digital camera, that is capable of giving you results that can hack it with the big boys (digital SLR), then you just might of found it.

Take a look at the information gathered and compiled, from my user feedback website, where you can review many electronic products based solely on USER FEEDBACK FORUMS to help you, in your research phase of this product.
