What makes a good car inverter? Car Charger Brand


Car inverter on the market there are two types of cigarette lighter-type universal car charger is 5V/12A current output, can be provided to mobile phones, digital products charge. Another is the car inverter charger, which is transferred 220v 12v car  wind inverter .

Therefore car charger is in great demand, and the production threshold is not high, so the market appeared a large number of low-quality car charger brand. These car charger variety, the price gap large, if buy counterfeits products, then it is likely to burn automotive fuse and digital products, they may even endanger personal safety.

Interpretation: Car inverter which features?

Inverter voltage DC into 220 volts AC electronic devices. Typically, car inverter is 12V turn 220V electronic products. Market, many car inverter product also integrates the "car charger" function.

Such as the above-mentioned MIG car inverter, 12V switch 5V also has the function, so you can use as a car charger. (Note: The phone voltage is 5V).

Analysis: How much car  dc ac converter  prices

For universal car charger, rechargeable lithium batteries are mostly used in the field of portable, this car charger Price only need three to four yuan. This common type car charger for mobile phones, ipad and other products charge.

Car inverter price is higher than ordinary car charger prices. Proposed purchase price of 200 yuan -300 yuan car inverter products. Car inverter is relatively higher than wide scope, can provide power to the TV, laptop computers, game consoles, etc. Almost all use electrical appliances.

Recommended that owners Reference (http://nanjingwanglei.com/?p=383) This article describes car inverter within the price. Articles within the recommended three car inverter Taobao most popular car inverter owners, reliable, and affordable.

Share: car charger (car inverter) choose Notes

1, buy car charger, pay attention to the voltage and current equipment size, generally portable, handheld terminal products of standard input voltage is 5V/700MA, while the iphone is 5V/1A.

2, know their car cigarette lighter output voltage, car output voltage of 12V, truck 24V. So universal style car charger (12v) most suitable for 12V cars, generally on the market are car inverter 12v 220v in turn.

3, note that the conversion efficiency of power inverter on the market now flowing car inverter power is virtual standard was very high, the conversion rate will probably only 70% to 80%, and relatively good quality .

4, select the car power inverter, choose the relatively common power has 100W, 200W, 300W, 500W and other specifications. Recommended that owners best choice 200w or 300w car inverter.

Ordos Desert Argonaut


This city is located in the hinterland of the plateau, once said that "proud" (cashmere, coal, rare earth, natural gas) is known. 2011, the total GDP beyond Erdos, Xi'an, Northwest became the first; per capita GDP exceeded Hong Kong, becoming the first in the country. Local people in every 228 have a billionaire, every 16 people will have a multi-millionaire.

Reporter purpose of this trip is a radius of 1.

860,000 square kilometers of China's seventh largest desert - Kubuqi desert.

In Inner Mongolia, has been circulating a jingle: 50s wind inverter pastures of cows and sheep, 60s deforesting chaos wasteland, 70 years into the back without hiding the sand, sand confrontation 80s who do not give 90s desert resources treasure.

Twenty years ago, Kubuqi barren desert, sand filled Kazamaki dance, year after year after year in the sand into the back, and even the birds stop looking, known as the "sea of ​​death."

Today Kubuqi blue sky, lush vegetation, Ouniao Xiangji, wearing sand roads criss-cross, ecology and livelihoods into account, both sand and rich, vibrant sand industry have brought the film "Sea of ​​Death" has become a veritable gold mine.

Salix: From Shaohuo to the "cash cow"

Fu source Salix base from Erdos Dalateqi 40 kilometers east Damon, Wang Group building. Group plans to build Salix base size 300 acres, a total investment of 290 million yuan.

Mongolia east, deputy director Feng Junqi Wang told reporters: "In the past, the management and protection of Salix cultivation and the enthusiasm is not high, farmers and herdsmen in the stubble after Salix firewood due to the coal-rich Ordos region, many farmers Salix pastoralists would not even cut firewood, causing 60% of Salix because they can not stumping, and finally turned into a desert deadwood. "

Reporters learned at the local, Salix species as one of the major anti-desertification, not only has a strong anti-erosion, anti-sand damage the sand-fixing function, or a good paper material, biomass raw materials and animal feed ingredients .

Salix is ​​an excellent paper and cardboard materials, Salix total fiber content of 75.83%. Mongolia east, Wang has worked with national and Paper Research Institute Group, to develop the Salix paper pulp as a raw material technology, manufacturing high-strength corrugated paper and testliner. Salix as raw material with cartons that environmental protection, strength and good, especially for the food packaging industry.

Pingjun Qi told reporters: "Salix addition to paper, you can also make furniture using particleboard."

Left Salix base, reporter and his party went to the East Dalin Sha industrial particleboard plant, raw particleboard is Salix. Pingjun Qi told reporters: "This particleboard plant is under construction in 2010, plans to invest nearly 400 million yuan, designed annual production capacity of 100,000 cubic meters, is expected to be able to put into operation later this year."

Reporters saw the equipment has been installed within the plant is ready, the plant also has completed construction. Also, a place not far from the factory, Liang Feng Shui 8000 kilowatts of  SUNGOLDPOWER photovoltaic power plants are under construction. This reporter saw rows of solar panels have been installed, the construction of solar power plants in the desert, coming around the plant will supply electricity.

In addition, accounting for about 15% by weight of Salix, rich in vegetable protein twig twigs and grass seed mix between Salix, you can also be processed into cattle, sheep, rabbits quality feed.

Salix is ​​an excellent biomass feedstock. In the desert plants, Salix premier heat, electricity and heat fairly common, but harmful gases produced by combustion with very little residue. In addition to using Salix generation companies, and then sell electricity directly to obtain economic benefits, its "green electricity" attribute can also be carried out in the international carbon trading. Reporters learned at the local, in the Mu Us Desert, there is a sand Liuzuo Sheng enterprises to use biomass project has become the world's first use of desert shrubs biomass direct combustion power generation projects.

In Kubuqi desert, east Damon ancient kings Salix processing enterprises represented the rise, led by local farmers and herdsmen massive planting of Salix, not only the local desertification hazard has been effectively controlled, the ecological environment has improved significantly, but also as "second smallest fuelwood" found a way out of Salix, Salix local farmers and herdsmen to increase due to a growing revenue, the original Shaohuo now become a "cash cow."

African solar booming referred to or into the secret weapon of economic development

The United States "fortune" magazine web site reported on June 25, according to African areas not covered by the grid land, this is for new renewable energy - solar ground provides a good opportunity in Africa.

Due to the imperfect state grid, despite traditional kerosene used widely, but the construction of concentrated solar power now has become more and more African countries.

Africa solar energy is very abundant, entrepreneurs called the paradise of the renewable energy.

The value of renewable energy in Africa from $2004 in 750 million, soared to $2011 in 3.6 billion, broad prospects abnormality.

Some companies to use high-tech will resources into good.

The phoenix international is one of them. The company developed a portable solar power stations can not charging the mobile phone service grid coverage area.
